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. Kerry Olszewski 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. Kerry Olszewski, though! Through regular checkups and cleanings at our Mill Creek 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!

Dr. Kerry Olszewski and our team at Mill Creek General Dentistry frequently get questions about cavity causes and prevention. You brush twice a day and floss regularly. You rinse with mouthwash, just like the dentist recommended. In fact, you can’t remember the last time you had a cavity, but you think it was when you were a little kid. In all seriousness, you thought only kids got cavities.

The Signs and Symptoms of a Cavity

It’s believed that roughly 90% of North Americans will get at least one cavity in their lifetime. Those other ten percent, it seems, can eat as much pie, cake, and sugary cereals and sweets as they want. That’s not really true; just a stab at dental humor, and it was as bad as the pain your cavity is probably giving you.

When a cavity is in its initial stages, you will often be symptom-free and experience no discomfort at all. It’s not until the tooth decay has reached a certain level that you will begin to notice the signs and symptoms. While a toothache and sensitivity to hot and cold foods and liquids are surefire signs that you have a cavity, there are lesser-known symptoms as well. If you’re experiencing any of these warning signs, you may want to consider making an appointment with our office as soon as possible:

• Persistent bad breath or a bad taste in the mouth
• When you bite down, there is a sticky, tarry feeling
• Puss or discharge around a tooth
• A visible discoloring, usually black or brown
• Small pits or holes in the tooth

Routine dental care is important. While good oral hygiene, a healthy diet, and regular cleanings will deter the formation of cavities, they do not constitute a foolproof practice. A cavity can occur at any time, no matter what your age. Bacteria causes tooth decay, and no amount of brushing, flossing, and rinsing will eradicate all the bacteria from your mouth. If you think you may have a cavity, please contact our office immediately.

Many adults wonder if they should continue to receive fluoride treatments. Our team at Mill Creek General Dentistry wants to set the record straight about the usefulness of fluoride treatment for adults.

There are several reasons fluoride treatments could be beneficial to you as a grownup. If you have a high risk for cavities, topical fluoride applications can cut down on that risk.

If you’re experiencing gum recession that’s softening your enamel, fluoride treatments can slow down that process. Fluoride treatments may also protect expensive restorative work on crowns or bridges that may be adversely affected by plaque.

In addition, fluoride can also protect teeth in adults who have orthodontic braces or who sometimes neglect to keep up with daily oral hygiene regimens such as flossing and using mouthwash.

Do you have sensitive teeth? Consuming foods that are highly acidic or using teeth-whitening products can lead to irritated gums. Fluoride treatments remineralize your enamel and reduce sensitivity.

If you’ve undergone radiation treatment for cancer, fluoride can help restore any dry-mouth damage that may have developed during that time. Saliva acts as a buffer against the foods we eat, and without enough of it you may be more likely to get cavities.

In general, fluoride treatments are not always necessary for adults, but they can be beneficial to your overall oral hygiene depending on your situation. If you fall into one of the general areas listed above, ask about a fluoride treatment during your next visit at our Mill Creek office.

We can also go over your options to treat other issues you may experience in terms of your oral health. Until then, make sure to take care of your teeth properly and use toothpaste or mouthwash that contains fluoride on a regular basis.

When it comes to dental hygiene, “going green” is not the first phrase that comes to mind. But if you are brushing properly, you are also replacing your toothbrush every three to four months as the bristles become frayed and wear down. Sure, that’s a tiny amount of plastic from each of us going to our landfills, yet it adds up to millions of brushes a year nationally. If you are concerned about reducing your carbon footprint while reducing your risk of cavities, there are several new toothbrushes designed to make brushing more eco-friendly.

Biodegradable Toothbrushes

Some brushes claim to be completely compostable. These models generally have heads fitted with boar bristles and handles manufactured from sustainable woods or bamboo. Boar bristles aren’t for everyone. Some users complain of the taste of the bristles, and boar bristles might be harsher than the soft bristles we recommend to protect both enamel and gums. There is also some concern about bacteria growth on organic bristles.

Earth-friendly Handles and Bristles

If you prefer the consistency and texture of regular synthetic bristles, you can still opt for a brush with a handle of sustainable wood or bamboo. You can also select PBA-free bristles, bristles made primarily of castor oil, or bristles that use natural ingredients in combination with synthetics.

Reduce, Reuse, Recycle

If these exotic brushes aren’t for you, there are more conventional choices that will save energy and cut down on waste.

• Reduce the amount of electricity you use for your electric toothbrush with a model that requires less charging time.
• Reuse your toothbrush by buying one with a handle made of metal, natural materials or plastic and replace the detachable head every three months.
• Recycled plastics can be found in the handles of some toothbrushes, and many brushes come in recyclable packaging. Every bit helps!

If you decide to use one of these green products, remember that your dental health is still the primary goal. Be sure the bristles of your brush are soft enough to protect your gums and enamel and can reach all the places you need to brush. The handle should be easy to grip and the head should be a comfortable fit for your mouth. It’s always best to choose products with a seal of acceptance from your local dental association, or talk to us about greener alternatives during your next visit to our Mill Creek office. Luckily, there are several workable options to protect the health of your family's teeth while still being mindful of the health of our planet.
