What is fluoride gel tray therapy

Not long ago,  a friend told me she has visited a dental clinic near her place. She was given ‘fluoride treatment’ on the chair by the dentist. As it was covered by her insurance, she did not asked too much questions about it. She then rang me up the next day and asked about this ‘fluoride’ thing. What is ‘fluoride treatment’?

The goal of a fluoride tray treatment is to help prevent new decay. The fluoride strengthen the teeth and harden them.  It is particularly useful for patient with dry mouth or have difficulty brushing regularly.

You see, fluoride is obtained in two forms: topical and systemic. Topical fluorides strengthen teeth already present in the mouth. In this method of delivery, fluoride is incorporated into the surface of teeth making them more decay-resistant. Topically applied fluoride provides local protection on the tooth surface. Topical fluorides include toothpaste, mouth rinses and professionally applied fluoride gels and rinses.

Systemic fluorides are those that are ingested into the body and become incorporated into forming tooth structures. Systemic fluorides can also give topical protection because ingested fluoride is present in saliva, which continually bathes the teeth providing a reservoir of fluoride that can be incorporated into the tooth surface to prevent decay. Fluoride also becomes incorporated into dental plaque and facilitates further remineralization. Sources of systemic fluorides include water, dietary fluoride supplements in the forms of tablets, drops or lozenges, and fluoride present in food and beverages.

Do Clean Teeth Protect Against Heart Disease?

(Reuters Health) – Older adults who get thorough dental cleanings may be somewhat less likely to have a heart attack or stroke than their peers who are less careful about oral hygiene, a new study suggests.

The study, of nearly 22,000 Taiwanese adults age 50 and up, found that those who’d had a professional tooth “scaling” in the past year were less likely to suffer a heart attack or stroke over the next seven years.

Tooth scaling, sometimes called a deep cleaning, involves removing the “plaques” that can build up on the teeth and deep in tooth pockets within the gum line. Those plaques harbor bacteria that can lead to gum disease.

The new findings, reported in the American Journal of Medicine, do not prove that a good dental cleaning will cut your risk of heart problems.

But the study is in line with past research that has linked gum disease to an increased risk of heart disease, said lead researcher Dr. Zu-Yin Chen, a cardiology fellow at Taipei Veterans General Hospital in Taiwan.

Since gum disease is caused by bacterial infection, researchers suspect that it may contribute to heart attacks or stroke by causing a chronic state of inflammation in blood vessels.

And studies have shown that treating gum disease can cut the levels of inflammatory substances in the blood, Chen told Reuters Health in an email.

Still, no one knows for sure whether a regular visit to your dentist can prevent a future heart attack.

For the study, Chen’s team looked at insurance records for 21,876 adults age 50 and older. Taiwan’s national healthcare program pays for tooth scaling, whether a person has severe gum disease or not.

About half of the people in the study had had a tooth scaling in the past year, while the rest had not.

Over the next seven years, 1.6 percent of the tooth-scaling group suffered a heart attack and 8.9 percent had a stroke.

In the comparison group, 2.2 percent had a heart attack and 10 percent had a stroke.

The researchers then weighed some other factors, like whether people had chronic health conditions such as diabetes, high blood pressure or kidney disease. It turned out that a deep tooth cleaning was linked to a 31 percent reduction in the risk of a future heart attack, and a 15 percent dip in the odds of a stroke.

People who got deep cleanings more than once every two years during the follow-up period had even lower risks of cardiovascular “events.”

But the study also had a number of limitations. An important one, Chen said, was that the researchers had no information on people’s smoking habits, weight, diet habits or family history — all prime factors influencing the risks of heart attack and stroke.

It’s also impossible for the study to determine whether people who get regular dental cleanings might also have a healthier lifestyle in other ways.

For now, the researchers recommended taking care of your oral health for the sake of your oral health — with the possibility of benefiting your heart health as well.

“Bad dental hygiene is detrimental to our health, so it’s very important to take care of your teeth,” said Chen, who presented some of his team’s results last November at the American Heart Association meeting.

What is Abrasion Cavity?

 

 

Abrasion Cavity is what causes tooth sensitivity in most people. It occur at the gum margin and is commonly caused by heavy tooth brushing, among other factors. The exposed underlying dentine or cementum layer is softer than the outer enamel layer, so it mean the cavity quickly deepen if you continue to leave it alone and brush hard.

A simple tooth coloured filling is all it take to relieve your tooth sensitivity. This restoration protect the root surface from being damaged again.

For long term maintenance, you should use a soft toothbrush so that you do not need to replace your filling too often.

Why do scaling and polishing?

The above picture was taken from a lady whom i have just completed scaling and polishing. Decided to post this picture together with the question: “Why do scaling and polishing? “. The answer seem obvious enough. Everyone want their mouth clean and smelling good! That is why you visit your dentist every six months, right?

A survey was carried out in Singapore last time and it showed only about half of people in Singapore visit their dentist every six months. Why? The answer is really simple. NO PAIN, so no need to visit dentist.

Calculus or tartar do not cause pain. They accumulate on on your teeth over time and your toothbrush cannot get rid of them. They harbour bacteria and cause your gums to bleed or appear red.  The right side of the above picture showed what you should have after scaling and you should maintain that as well as you can. If you can’t, please do yourself a favour.  Let your dentist clean your teeth for you. :)

Porcelain Veneers: Instant Braces.

Hi, how is your 2012 so far? Mine is great! I am pleased to share with you my 2012 first article that has just been published. The magazine is available in bookstores since 17 feb. Please feel free to email me your feedback and questions.

Some called it “Instant Braces”. Are you suitable?

Recently, one of my clients showed me a photo of herself in her twenties (she is now in her forties), and requested for porcelain veneers. Indeed, she is one of many patients today who know the benefits of cosmetic dentistry and how it can rejuvenate your smile.
Over the years, porcelain veneers have become increasingly popular and are a great durable option for changing the size, shape, position and colour of your teeth.

What are dental veneers?

There are two types of veneers: Porcelain (laminates) and composite (resin) veneers.

Porcelain veneers are ultra-thin, custom-made laminates that are permanently fixed directly to the front of your teeth. They are used to close gaps, straighten teeth, replace worn edges, or mask discoloured teeth that for some reasons did not get white enough with whitening treatment. You need at least two visits before your veneers can be fitted.

Composite veneers, on the other hand, are made of resin that are placed on your teeth in one session. They are more susceptible to staining and are not as strong as porcelain veneers. But they are less expensive than porcelain veneers.

For both veneer types, a very thin layer of tooth structure ( thickness of your fingernail) usually need to be removed by your dentist before the veneers can be fitted. Veneers can be placed on a single tooth or multiple teeth.

Porcelain veneers are usually preferred over composite veneers by patients because of their closeness to natural teeth.

Why porcelain veneers?

You may consider veneers if you have the following conditions:

-Chips or cracks on your front teeth that can no longer be repaired by tooth coloured fillings.

-Gaps between your front teeth.

-Severely discoloured teeth or stains that cannot be improved with whitening procedures.
( eg amelogenesis imperfecta, tetracycline staining)

-Crowded teeth that you want to straighten or mask

-Teeth that you want alter, be it position, length or width.

Please consult your dentist to have a proper assessment before you commit to this cosmetic treatment. The best candidates for all veneers are people whose teeth are healthy and free from decay and gum disease.

Advantages of porcelain veneers
-Fast results. You can usually have your new smile in just two visits. That is the reason why some dentists call them ‘instant braces’ as traditional braces typically take one to two years. But do remember that not everyone is suitable for such quick fix, especially if your teeth are very crowded.

-Durable. Porcelain veneers are nearly as strong as healthy natural teeth.

-Natually looking and aesthetically pleasing.

Disadvantages:
-More expensive than composite veneers or other tooth coloured fillings (bonding)

-Irreversible. A small part of your teeth are removed in the process.

-Though beautiful, they are not indestructible. Just like your natural teeth, porcelain veneers can chip or break. Do not use your veneers to bite on your nails, ice, pencil or open bottle caps. If you grind your teeth at night, please invest in a nightguard.

What are new in porcelain veneers?
Some of you may have heard “no prep’ veneers or “ snap-on veneers”. These are veneers that you can ‘wear’ whenever you need. According to the manufacturers, no part of your teeth need to be removed. From my personal viewpoint, in order to maintain natural shape and size, you almost always have to remove some tooth structure and replace it with porcelain. Unless you have many gaps or teeth that slant in towards your tongue, you may end up with bulky, fake-looking teeth. Hence, be cautious if you are considering this new procedure.

Conclusion

A dazzling smile can boost your self-confidence, increase your chances of career success or even ignite romance. With proper care and maintenance, porcelain veneers can last you a long time while keeping your smile healthy and sparkling forever.

What is Invisible Braces?

Lately, “Invisible Braces” seem like the in-thing nowadays. You can probably spot them on advertisements, magazines and even your children are talking about it!

So, what exactly are “Invisible Braces” and what can they do for you and your children?

What are “Invisible Braces”

Since time immemorial, braces are often associated with pain and ugly metallic wires  in the mouth. Today, just like how Iphone have changed people’s lifestyle, the space age CAD-CAM technology have revolutionized the way human teeth are straightened.

The term “ Invisible Braces” used here refer to clear and removable acrylic appliances known as aligners. These are worn over the teeth and are changed every two weeks, for a period of a few months to a year or more.  They are convenient and easy to use.

To understand this new concept, you need to first know the different types of traditional braces.

-          Metal braces.

School children love this! They get to choose different colour for the elastic module every month. With metal brackets, treatment is simple and efficient.

 

-          Ceramic braces.

This is highly popular among the GenX and GenY ,  and most of them prefer a combination of ceramic ( upper teeth) and metal ( lower teeth) brackets. Treatment time is generally slightly longer than metal ones.

 

-          Lingual braces.

This is the  “invisible” braces of the last decade, and is the top choice for those in the entertainment and mass media industry, despite longer treatment time and much discomfort.

With today’s clear and removable aligners, there is a great paradigm shift in the way crowded teeth are treated. Despite higher cost and longer treatment time, it has gained extremely wide patient acceptance worldwide.

Why do invisible braces?

 

Just like traditional braces, you ought to ask yourself why do you want to straighten your teeth? Two common reasons for doing braces is Aesthetic and Health, the former being the more common motivator for people to seek orthodontic treatment.

 

The advantage of invisible braces is obvious -  aesthetic. The clear aligners are virtually undetectable and they go unnoticed when speaking in social situations. They can give you that beautiful smile by straightening your teeth without anyone knowing. For children, you can still play your favourite sport or musical instruments!

 

As you can remove them anytime, it is easy to brush and floss. Hence, oral hygiene is well maintained. This kind of “wire-less” treatment also take away the discomfort and ulcers associated with metal wires used in traditional braces.

Are you or your child suitable for invisible braces?

As a father of two, I can understand most parent’s concerns. For treatment to be successful, aligners need to be worn for at least twenty hours per day. Hence, it may be more suitable for older teenagers and even then, the parent, the child and the dentist need to work together as a team and with proper communication, invisible braces may be a viable option for your child.

Visit your dentist for a consultation to ascertain if invisible braces is suitable for you or your child. Factors such as extraction, jaw size discrepancy, poor patient compliance, can influence the prognosis. Sometimes, you may even require a combination of both traditional braces and the aligners, if your dental bite is severe. Remember: there is no perfect system and every cosmetic treatment has its pros and cons.

So, if you are deemed suitable, you can then say good bye to metal brackets and wires, and hello to removable aligners ( such as Invisalign, ClearCorrect, ClearAligner ) , the “contact lenses”  for your teeth.

When can my child start braces?

As requested by readers, this is the FULL text of the latest dental article released this month. I have put it up here for your reading pleasure. Please read on:

When can my child start braces?

Seeing a smile on your child’s face is one of the most gratifying things about being a parent. But keeping that smile healthy and beautiful require good dental care and awareness that starts early in life.

All children should have an orthodontic screening no later than age 8.

When most parents think of braces, they think of teenagers. This is normal, as most children start to wear braces between age of 10 to 14 when most adult teeth are grown. However, by age 8, your dentist can spot subtle problems with jaw growth and emerging teeth although some baby teeth are still present. That is important, because some orthodontic problems are easier to correct if they are diagnosed early.

For these reasons, it is recommended that your child should get an orthodontic screening as early as 7 to 8 years old. While your child’s teeth may appear to be straight, there could be problems that only dentist can detect. Of course, the check-up may reveal that your child’s bite is fine, and that can be comforting news.

For each patient who needs treatment, there is an ideal time for treatment to begin in order to achieve the best results. In some cases, your dentist might find a problem that can benefit from early treatment. Early treatment may prevent more serious problems from developing, and may make treatment at a later age less costly and painful.

What is orthodontic early treatment

Typically, early treatment involves the use of orthodontic appliances, which may be removable, to guide the growth of young bones to create a better environment for adult teeth as they grow. In some cases, results that would not be possible once the face and jaws have completed its growth can be achieved. Early treatment is known as Phase One in orthodontic treatment. It give us the chance to do the following:

  • lower the risk of trauma to upper protruded front teeth
  • guide the jaw bone
  • correct harmful oral habits
  • improve appearance and self-esteem
  • guide permanent teeth into a more favorable position
  • improve the way lips meet

In other cases, your dentist may adopt a “wait-and-see” approach, checking on your child periodically as the permanent teeth come in and the face and jaws continue to grow.

 

Signs that your child need braces

It is not always easy to tell if your child has an orthodontic problem. Even teeth that look straight may have a hidden bite problem. As such, it is important to take your child for that first orthodontic screening no later than age 8.

Below are some clues that may indicate the need for orthodontic intervention:

  • Protruding teeth
  • Early or late loss of baby teeth
  • Thumb sucking
  • Difficulty in chewing or biting
  • Mouth breathing
  • Crowded and misplaced teeth
  • Jaws that are too far forward or backward.
  • Biting the cheek or biting onto the roof of the mouth
  • Upper and lower teeth that do not meet, or meet in an abnormal way
  • An unbalanced facial appearance
  • Grinding or clenching of the teeth

Beautiful Smiles in Beautiful Faces

Every patient is unique and your child may or may not benefit from early treatment. The ideal time for braces depends on the growth progress of your child’s jaws and face.

Through early check-ups, your dentist can monitor the development progress of your child’s teeth and jaw, and alert you to changes that may occur as your child grow. In addition to improving oral health, orthodontic treatment can provide the confidence that comes with a healthy and attractive smile for years to come.

I just had a upper premolar extracted. Can i leave the gap alone?

If you have had a back tooth extracted, do you know that the opposing tooth actually become useless? In other words, the rest of the teeth in your mouth has to work harder to make up for the loss of these 2 teeth. The chewing teeth are our molars and premolars. That is , everything behind the canines ( the pointed teeth at the corner of your mouth).

If your dental bite is not stable, the opposing tooth may ‘grow” longer and enter into the missing gap. This process is called ” supra-eruption”, meaning that the tooth has super erupted due to a lack of opposing tooth for it to work with.

Some people lose all their back teeth and forced by economic circumstances to chew on their incisors and canines. This is not the way nature plan it. As a result, the wear rate of their front teeth can be alarming, especially once they wear through the harder layer of enamel.

Another problem that arises when you lose a back tooth is that the surrounding teeth tend to fall into the gap. They tilt sideways often ending up at 45 degress or more over a period of about 5 to 10 years. As a result, the flat surface on top of the tooth, which used to meet so nicely with the opposing tooth, now meets with a 45 degree gap. This reduce the crushing and grinding power of the molar by about 80 %.

While you may not die of malnutrition, you will definitely notice a significant loss of chewing power. Hence, you may find less satisfaction with your eating because you are not grinding your food as finely and releasing the flavours.

You will also be swallowing food that has not been sufficiently ground up and mixed with the enzymes in the saliva, hence adding extra load to your digestive system. If your digestive enzymes cannot cope with the load, you may have some intestinal tract discomfort such as excess gas.

See your dentist to discuss the options of tooth replacement and remember to plan it early.

My kid has black stubborn stains on her teeth. Can it be cured?

Relax! You can set your mind at rest knowing that this is not an infectious disease. Neither will the stains cause any cavity or other health problems. This kind of dark stains that are sometimes found in young pre-school kids’ teeth are termed as ” chromogenic stains”.

First time parents, especially mothers, are usually very worried when they discovered that their children have dark black stains on the baby teeth. No matter how hard and often they brush, the stains do not go away, right? Furthermore, the stains quickly return after your kids’ dentist has polished them away. Sound familiar?

Chromogenic stains usually pose a cosmetic issue when the child laugh or smile, and can be teased by classmates. You just need to bring your child for more frequent visits to the dentist for scaling and polishing. They are not cavity or any hereditary discolouration of teeth. The stains are caused by a certain type of harmeless bacteria group in the mouth. Most of the times, the stains are usually seen on baby teeth and do not carry on into adulthood.

Teeth Whitening in a 70 year old patient

This picture is taken 14 days after at-home teeth whitening. Only the upper teeth are treated, while leaving the lower ones alone for the time being. My elderly patient is extremely pleased when her friends notice the change in her smile. She quirked ” Starting afresh at a ripe old age of 70 ! ”

Ironically, she started the treatment with no intention of having a set of whitened teeth, but to have cleaner teeth after she was told by me that carbamide peroxide ( the gel used in teeth whitening) can kill germs. She has receding gums and many exposed root surfaces. This treatment serve as a form of decay control, especially she likes to eat sweets and chocolates often.

Nowadays, she says ” My teeth are squeaky clean!”  and who would imagine she actually have phobia of seeing dentist last time?

I keep having bleeding gums every month during my periods.Why is this so? .

During puberty, increased level of hormones such as progesterone and oestrogen can cause your gum to be more sensitive, leading to a greater reaction to food particles and the presence of plaque. The gums become swollen, turn red and may feel painful to touch.

Some women experience menstruation gingivitis which is characterized by bleeding gums, bright red swelling of the gums between the teeth and sores or ulcers in the mouth. The symptoms usually clear up once period starts.

It is important to maintain good oral hygiene during these hormonal changes so that your bone and gums surrounding the teeth remain healthy.
