Protecting your children is one of your most important roles as a parent or caregiver. Dental sealants are one way you can protect your children's teeth from the ravages of tooth decay, drilling and fillings — and they can be applied simply, comfortably and quickly right here in our office.

What is a dental sealant?

A dental sealant is a thin, plastic film that is painted onto the tiny grooves on the chewing surfaces of the back teeth (usually the premolars and molars) to prevent caries (cavities) and tooth decay. And by allowing us to use sealants to seal these little nooks and crannies where your child's toothbrush can't reach, you will dramatically reduce their chances for developing tooth decay. This one, simple and quick office visit could save you both money and time with fewer dental visits and healthier, cavity-free teeth.

So will sealants guarantee no (or no more) cavities?

No, just like life, there are few guarantees. Your child's oral hygiene, regular dental visits, fluoride, sugar consumption and genetics are the other important factors that will determine to what degree your child experiences tooth decay. However, research shows that pit and fissure (chewing surface) decay accounts for approximately 43% of all decayed surfaces in children aged 6 to 7, even though the chewing surfaces (of the back or posterior teeth) constitute only 14% of the tooth surfaces at risk. This demonstrates the vulnerability of the chewing surfaces of the posterior teeth to decay. By placing a protective seal over the areas of teeth at risk, you can effectively and proactively protect your children's teeth.

How long do sealants last?

Research has shown that some sealants can last up to 10 years. However, if you opt for sealants for your children's teeth, we will closely monitor them with each office visit to ensure that they are still doing their job. As needed, we can apply more sealant.

Dental decay is an infectious and very common disease, but it's also very preventable. Today's dentistry has many tools at its disposal to accurately determine your risk for tooth decay, lower it, turn it around, and completely prevent it. What's more, we can even reverse early decay. You might never have to see or hear the drill again.

Striking the right balance between factors that promote oral health and those that cause disease is of the utmost importance. And knowing whether or not you have indicators of disease or risk for tooth decay is a great place to start.

We will scientifically calculate your risk for tooth decay by:

1. Recording and monitoring your oral and dental health: Our risk assessment/evaluation form allows us to gather information about critical dental health habits. Oral hygiene habits, use of fluoride toothpaste, tobacco smoking, frequent snacking on sugary foods and beverages, and past experience of decay are all examples of disease indicators that will help gauge your level of risk. For example, using fluoride toothpaste decreases your risk, but smoking and between-meal snacking increases it.
2. Testing for decay producing bacteria: You've probably heard of dental bacterial plaque, the biofilm that sticks to your teeth, forming in the tiny little grooves on the biting surfaces of the teeth where decay starts (and along the gum line). Today, acid-producing bacteria responsible for causing decay can be tested by simply sampling your biofilm on a swab, and placing it in a meter to accurately determine acid-producing activity. A high number indicates high risk. You can see it for yourself in less than a minute.
3. Saliva testing: A simple history will tell us whether your mouth is dry or moist most of the time. A saliva test will tell us if your saliva is acidic or neutral. A dry acidic mouth promotes decay, while a moist neutral mouth with healthy saliva promotes health. Measuring salivary “pH,” the measure of acidity, is another factor for determining your risk for decay and reversing it. Special rinses can help reduce decay-producing bacteria and reduce acidity.
4. Very early decay detection: Modern ultra-low-dosage x-ray equipment allows us to determine the very earliest signs of decay. Decay that is detectable with the naked eye (or feel with a dentist's instrument, an explorer) is already at an advanced stage. Catching the disease very early with the help of this sophisticated equipment can allow us to reverse early decay before it has even turned into cavities. It can actually be reversed with remineralizing fluids, rinses that put calcium back into the tooth surfaces reforming and hardening them.

This is a new and exciting era in the fight against tooth decay and we have all the tools to determine your decay risk and reverse it.

If you like soft drinks and carbonated colas, beware. Acids in these drinks may be dissolving the minerals in your teeth — a process called chemical erosion. And don't think that natural fruit juices or sports and high energy drinks are any better than sodas. They also contain acids that dissolve the surface enamel of your teeth. Once your enamel is lost, it is gone forever. It cannot naturally recover.

Sadly, teeth in children and teenagers — an age group most likely to drink large quantities of soda and juices — may be more easily eroded by acids. These youngsters have not had long-term exposure to fluorides which harden tooth enamel and protects them from acid erosion.

The Difference between Erosion and Decay
Chemical erosion is not the same as tooth decay (cavities). In chemical erosion, acids in your mouth react directly with minerals in the outer enamel of your teeth. In the case of tooth decay, bacteria in dental plaque (a bacterial film that forms on your teeth) utilize the sugars in the drinks and produce acids that attack your teeth.

After Acidic Exposure, Wait 30 Minutes to an Hour before Brushing
You may think that the solution to chemical erosion is to brush the acidic solution from your teeth as soon after drinking them as possible. But tooth brushing immediately after can actually accelerate chemical erosion and make it worse. After they are bathed in an acidic solution, minerals in the tooth surface become partially dissolved. Brushing at this time may brush away the affected layer. If you wait a half hour to an hour, your saliva will have time to neutralize the acids and harden the tooth surface by adding minerals back into it.

Drinks Less Likely to Cause Dental Erosion
Instead of drinking colas and sports drinks, stick to water and/or milk, which have the added benefit of supplying calcium to help add minerals back to the tooth surface.

If you must sip on juices or soft drinks, try to do so only at mealtimes. This is preferable to drinking them all day long, which leaves your teeth constantly bathed in an acid solution. Avoid swishing the drinks in your mouth, and sip them with a straw to reduce contact between acidic drinks and your teeth.

Tooth decay is not trivial. It's a worldwide epidemic, one of the most common of all diseases — second only to the common cold. It affects more than one fourth of U.S. children of ages 2 to 5 and half of those 12 to 15. Among adults, tooth decay affects more than ninety percent of those over age 40.

Prevention of cavities starts with a healthy diet and effective brushing and flossing, but it is much more complex than that. Three strategies for reducing dental caries (tooth decay) include:

Protect with Fluoride and Sealants
This works best when fluoride is applied to the crystalline coating of your child's teeth just after they push through the gums (erupt). The fluoride becomes incorporated into the tooth's surface and acts as a barrier to decay. Studies have shown that low doses of fluoride are safe and effective.

Dental sealants are used as a companion to fluoride because they seal tiny pits and fissures in the tooth's structure, creating an even stronger barrier.

Modify Oral Bacteria
Every mouth contains bacteria, no matter how well you clean your teeth. Not all bacteria cause tooth decay. The problem bacteria are those that produce acid as a byproduct of their life processes. We can identify acid-producing bacteria in your mouth, you can reduce their concentrations using antibacterial mouthrinses such as chlorhexidine, and pH neutralizing agents (substances that reduce the amount of acid).

Reduce Sugars in Your Diet
Bacteria in your mouth ferment sugars and other carbohydrates, producing acids that eat into the mineralized outside structure of your teeth, the enamel. So eating fewer sugars — particularly added sugars such as those in juices, sodas, candy and other sweets — will help prevent decay. Your total sugar intake should be less than fifty grams, or about ten teaspoons, per day. If you begin to read labels showing sugar content of common foods, you may be surprised at the amount you consume without knowing it.

If you must snack between meals, non-sugary snacks like raw vegetables and fresh fruits create a better environment for your teeth.

Xylitol, an “alcohol sugar” used in some chewing gums and dental products, has been shown to reduce decay-producing bacteria.

Try these easy strategies to keep your teeth healthy and functional throughout your lifetime.

   True or False
9. The only side effect of too much xylitol ingestion is a possible mild laxative effect.
   True or False
10. The target dose of xylitol is one to two teaspoons spread throughout the day.
    True or False

1. True. Xylitol is a kind of sugar that does not contribute to tooth decay.
2. All of the above. It is also found naturally in some fruits and vegetables.
3. True. The others, mannitol and sorbitol, are used as sugarless sweeteners.
4. False. Unlike sucrose (table sugar), xylitol is NOT broken down by bacteria to produce acid. Xylitol also stops saliva from becoming acidic so your mouth becomes an unfriendly environment to acid-producing bacteria.
5. True. However, xylitol inhibits growth and attachment of the bacteria to your teeth, so it also inhibits transmission to your children.
6. False. Systematic use of xylitol chewing gum significantly reduces the relative risk of caries (tooth decay) when compared to chewing gums containing sorbitol/xylitol and sucrose. Xylitol gum also appears to halt the development of tiny cavities when compared to other types of chewing gum.
7. True. Use of these products seems to stop the progression of active decay.
8. True. Xylitol and your saliva combine to re-mineralize (harden) your teeth after an acid attack.
9. True.
10. True. This means two pieces of xylitol gum or two pieces of xylitol candy or mints should be consumed for five minutes four times a day after eating meals or snacks.
