Why Do Molars Seem to Get More Cavities?

February 17th, 2021

Probably because, for many kids, molars do get more cavities. So let’s answer two better questions: Why do molars get more cavities? And, how can we help prevent them?

It’s the Pits. (And Fissures.)

The reason molars are so useful—and more likely to develop cavities—is because of their shape. Unlike our front teeth, which are used to bite through foods, molars are used to grind and chew. That’s why they are so much larger, with a flat surface on top. Well, not exactly flat.

When you look at a molar, you’ll notice that the top isn’t really smooth at all. It’s covered with little indentations known as pits and longer grooves called fissures. These irregular features both trap food particles and make it more difficult for bristles to clean them away. Cavities in molar surfaces are so common that they even have a specific name: “pit and fissure cavities.”

But molar biology does not mean tooth decay is inevitable! There are steps you can take to protect your children’s molars as they grow, while you’re providing them with dental strategies that will keep their adult molars healthy and cavity-free.

Preventing Pit and Fissure Cavities

  • Don’t Just Brush—Brush Effectively

The first step in preventing any kind of cavity is brushing properly. Your child should be brushing at least two minutes, at least twice each day. And while the time we spend brushing is important, technique is also key.

When you’re showing your child how to brush, be sure that the tops of molars, upper and lower, get brushed thoroughly, with special emphasis on cleaning pits and fissures. Make sure the toothbrush is small enough to fit your child’s mouth comfortably and reach all the tooth surfaces. Replace worn-down brushes or electric toothbrush heads after three to four months when they no longer clean as effectively.

Your child will probably need adult supervision from toddler years through the early years of grade school to learn how to brush properly. This is time well spent, as your child learns cavity-preventing brushing techniques which will last a lifetime.

  • Eat a Tooth-Healthy Diet

Plaque bacteria use the sugars in our food to make acids. These acids break down the mineral strength of tooth enamel and eventually lead to cavities. And because pits and fissures are great hiding places for bacteria and food particles (especially sticky ones), molars are even more at risk for cavities. Limiting sugary, sticky foods like sweet treats and simple carbs helps reduce that risk.

Acidic foods like flavored juices, sour candies, sodas, and power drinks also weaken enamel and can leave teeth more vulnerable to decay. Help your child avoid cavities by limiting acidic foods and drinks, making them part of a balanced meal, and/or rinsing with water after eating.

  • Use Fluoride Toothpaste

Fluoride toothpaste not only reduces the risk of cavities, it also helps strengthen enamel that has been weakened by bacterial and dietary acids. Win-win!

  • Ask About Sealants

Sealants are invisible, safe coatings which protect molars by preventing food and bacteria from getting trapped in their uneven surfaces. The top of the molar is first treated with an etching solution to allow the sealant to bond tightly to the tooth, a thin coat of sealant is painted on, and then it’s hardened under a curing light. That’s all there is to it.

Sealants are often recommended when children’s permanent molars first erupt, when they are especially at risk for cavities. Sealants can last from three to five years (or even longer), and studies have shown a dramatic reduction in cavities for patients who use sealants compared to patients with untreated teeth. Depending on your child’s individual needs, Dr. DeCasperis might recommend a sealant for baby molars as well.

  • Regular Exams and Cleanings

It might be hard for you to tell if your child’s molars have been affected by sticky plaque, or sugary foods, or acidic drinks, or inadequate brushing, or any other potential cavity-causers. It’s not a difficult job for Dr. DeCasperis, though! Through regular checkups and cleanings at our Lebanon, NJ office, we will discover any conditions that might lead to cavities, and, if necessary, treat small cavities before they lead to more serious decay.

Statistically, childhood molars have a greater chance of developing cavities than incisors and canines. Help your child beat the odds by understanding why these teeth are at risk and by working with your dental team to give your child years of healthy teeth now and a future filled with beautiful smiles!

Dental Veneers

February 10th, 2021

Are you looking to improve the appearance of your front teeth? Dental veneers are widely used to improve the appearance of front teeth and are a much more conservative option than a full dental crown. Veneers can be used to improve the appearance of staining, large gaps, large fillings, chipped teeth, or overall shape. Veneers are a thin covering over the front and biting end of the tooth used to restore the beauty of a smile. Over the years we have helped many patients who opted for veneers and now have the confidence to smile again.

Dental veneers are made in a lab from long-lasting porcelain materials. The shade can be chosen to a desirable color to whiten the appearance of your smile. Dental veneers are usually placed on the anterior, or front teeth, where the chewing forces are not as hard as the back teeth. The process of placing veneers is relatively easy requiring only two dental appointments. In some cases, only one appointment is needed. It depends on the fabrication process.

The first appointment is to “prep” the teeth and take an impression to be sent to a lab to fabricate the veneers. Veneers are fairly conservative in the preparation as it requires a small amount of space to be created on the face (front), bottom, and sides of each tooth to allow space for the veneer to be placed and look natural. You will leave the office with temporary veneers for the next week or two while the permanent veneers are being made.

The second appointment is to place the veneers and make minor adjustments if needed. What a difference it makes in the appearance of the teeth! If you’re interested in learning more, give Dr. DeCasperis a call today!

When to Replace Fillings

February 3rd, 2021

A dental filling replaces and restores the health of a tooth that has been damaged. Often, the need for a filling results from a cavity due to a large amount of decay in a tooth.

Teeth may also require repairs after cracking from chewing on hard objects, trauma to the mouth, grinding or clenching of your teeth, uneven chewing pressure, or exposure to extreme hot and cold temperatures.

Over time, a filling may have to be replaced after normal wear and tear has occurred. There are signs and symptoms to watch out for if your tooth may need a replacement filling, or a new filling. Dr. Steven DeCasperis, DMD performs various types of filling treatments, depending on the damage to the tooth.

Common signs and symptoms to watch out for if you have a cracked tooth can include sharp pain when you bite down, pain that comes and goes, discomfort when eating or drinking, or a constant feeling that something is stuck in your teeth. The crack may not be visible to the eye, which makes it hard to tell whether a tooth is actually cracked.

Pain may come and go quickly when you bite down because you’re expanding the crack with the combined pressure of your teeth. If you notice this happening, contact Dr. DeCasperis right away so we can get X-rays of your mouth and quickly fix the problem.

If you’ve had a filling in your mouth in the past, you could be due for a replacement. The seal between the tooth and the filling may break down over time, after which bacteria can build up underneath the filling and cause more decay.

It’s vital to catch this early so a filing can fix the problem. If you wait too long, a crown or a root canal may be the only option. You may not notice that a long-time filing is cracked or worn down, because it can take a long time to feel any discomfort. This is one of the reasons we recommend a dental checkup every six months.

If you need a tooth filling or a replacement filling, different filling choices vary in price. Gold fillings and porcelain fillings are more expensive options that last longer -- typically around 20 years. Porcelain fillings match the color of the rest of your teeth, however, which makes them less visible.

Another option is amalgam, or silver fillings, that less expensive but may be more noticeable in visible areas of your mouth. Composite, or plastic fillings, are another affordable option that can be matched to the color of your teeth. Composites are more likely to wear out over time and not last as long: usually around three to ten years.

If you think a past filling might be due for replacement, schedule an appointment at our Lebanon, NJ office. Make sure to stay on top of your routine dental appointments in order to prevent decay from breaking down problem teeth.

If we catch the problem early, we can save you both money and time. Fillings can be a great way to resolve any existing teeth issues, and prevent extensive dental care practices from becoming necessary in the future.

 

What is Remineralization?

January 27th, 2021

“What is the strongest substance in the body?” If this question comes up on trivia night, be prepared to impress your team when you confidently answer, “Tooth enamel!”

Tooth enamel? The reason for this surprising answer lies in the biology of our teeth. Minerals make up well over 90% of our enamel, a much higher percentage than is found anywhere else in the body, including our bones. But unlike bone tissue, which can heal and regenerate, tooth enamel cannot. Even though it is extremely strong, enamel can be damaged by a process called demineralization.

Demineralization

Demineralization is a result of acids at work in our mouths. Acids actually break down the minerals in our enamel, making the enamel softer. Over time, bacteria attack deeper into the tooth, eventually leading to decay. Acidic foods like sodas, citrus, pickles, and coffee are obvious culprits in providing an acidic environment, but there are other problem foods as well. We all have bacteria in our mouths, which can be helpful or harmful. The bacteria in plaque use the sugars and starches we eat to produce even more acids.

This process is something that takes place very quickly. In fact, even brushing too soon after eating something acidic can damage the demineralized surface of a tooth. Waiting at least 20 to 30 minutes to brush gives our bodies a chance to restore the enamel surface in a process called remineralization.

Remineralization

Our bodies are actually designed to help protect our enamel, and the most important part of this process is saliva production. Saliva cleanses our teeth and reduces levels of acidity. And our saliva constantly washes important minerals over our teeth. Calcium and phosphate ions rebuild and strengthen molecules where demineralization has taken place. This process is called remineralization.

We have other ways to help the remineralization process along. Fluoride toothpastes and fluoridated water speed up the movement of mineral building blocks back to the surface of the tooth. Fluoride also strengthens our teeth so that they resist acids and demineralization better than teeth without fluoride, making them less vulnerable to cavities.

New products are available for home and professional use that are designed to increase remineralization—talk to Dr. DeCasperis at our Lebanon, NJ office if you would like the latest recommendations. In fact, talk to us about tooth-friendly menus, the best toothpastes, brushing techniques, and all the ways to keep your enamel its healthiest. You’ll be answering all those trivia questions with a strong, confident smile!
