Why Do Molars Seem to Get More Cavities?

April 24th, 2023

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. Kelly Peterson 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. Kelly Peterson, though! Through regular checkups and cleanings at our Marysville, WA 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 Sealants for Baby Teeth?

April 24th, 2023

Perhaps you’ve heard your friends talking about dental sealants, and how well they prevent cavities. And as soon as your child’s permanent molars come in, you absolutely plan to make an appointment at our Marysville, WA office for this treatment. But should you also be concerned with your child’s baby teeth? Could they benefit from sealants too?

Even though those beautiful baby teeth are going to be replaced with permanent teeth, they should still be protected. Primary teeth help with speech development, enable your child to develop proper chewing and eating habits, and serve as place holders so that permanent teeth can erupt in the correct place. That’s why you’ve been so careful to help your child brush and floss twice daily, and make regular visits to our office for exams and cleanings.

But some teeth are just harder to keep clean with regular brushing than others. Primary molars, just like permanent ones, have depressions and grooves on the chewing surfaces. These grooves collect bacteria and food particles that are hard for bristles to reach, providing a perfect opportunity for cavities to develop in those little molars.

Cavities are not the only problem which can affect primary teeth. Because baby teeth have thinner layers of protective enamel, a cavity can actually reach the pulp (the center of the tooth) more quickly, leading to pain and potential infection.

While baby teeth can be treated, with fillings, restorations, and even stainless steel crowns, preventing tooth decay is always our first, best choice. And dental sealants are recommended by the American Academy of Pediatric Dentistry and the American Dental Association as one of the most effective ways to prevent cavities in both baby teeth and adult teeth.

Dental sealants are safe and effective.  Sealants are thin coatings (usually a plastic resin or other dental material) that cover a molar’s grooves and depressions, making it impossible for bacteria and food particles to collect there. Applying them is a simple, pain-free process.

Each tooth will be examined first. If we find any signs of decay starting, we will gently treat that area before applying the sealant. After the tooth is cleaned and dried, an etching solution will be brushed on to the surface area being sealed. This etching roughens the surface so that the sealant will hold to the tooth more effectively. A thin coat of the sealant is then painted on and hardened under a curing light.

That’s all there is to it! Sealants typically last from three to five years, and some last even longer. Keep up your regular careful brushing and flossing, and we will monitor the condition of the sealants at each exam.

Talk to Dr. Kelly Peterson about dental sealants. We’ll let you know if your child can benefit from the procedure even before those baby teeth give way to permanent ones. It’s never too early to prevent tooth decay!

I have fluoride toothpaste and fluoridated water; do I need a fluoride treatment?

April 5th, 2023

Fluoride is a naturally found ion with a history of greatly reducing the incidence of tooth decay in children. However, over the past decade, people have increasingly consumed bottled water, most of which does not contain fluoride, and children are no longer getting the recommended dosage of fluoride. In addition, many areas do not add the optimum amount of fluoride to the town drinking water.

Everyone’s dental needs are different. The amount of fluoride a person needs is determined by age (children), tooth sensitivity, risk for cavities, and medical conditions. When a patient needs additional fluoride it can be applied in a foam or varnish.

Children receive additional topical fluoride because teeth in the early development stages have a higher mineral uptake. The future strength of the enamel depends on this. When a tooth absorbs the fluoride ion, it creates hydroxyapatite, a harder mineral compound than enamel alone.

Those who have a dry mouth from medication also need extra fluoride. A daily fluoride rinse and a semi-annual fluoride varnish treatment are standard. If you are on medicine for high blood pressure, anxiety, diabetes, depression, or cholesterol, you may fit in this category.

Cancer treatments can also greatly impact your oral health. Fluoride varnish treatments prior to, during, and after radiation and chemotherapy can be beneficial. There are other mouth conditions which coincide with cancer treatments which make it difficult to brush and floss daily, and can contribute to an increased risk for decay. An infection during cancer treatment can be especially harmful, which is why preventive measures are important.

Fluoride treatments, administered topically, are highly beneficial in preventing decay. Feel free to call Northwest Smile Design to schedule an appointment or if you have any questions.

Most Valuable Dental Treatments

April 5th, 2023

At Northwest Smile Design, we work to find a dental plan that will work best and most effectively for you. But we’ve found that three treatments tend to be the most common and useful. If you ever find yourself in any of the following situations, we suggest you look at these options.

If you’ve lost teeth due to trauma, fracture, or decay, dental implants are a great choice. With all the technology available to us now, dental implants look and function exactly the way a natural tooth would. They blend in perfectly and are custom made to fit you. They’re a great investment that will restore the balance to your smile.

If you struggle with stress and catch yourself clenching or grinding your jaw, you may want to consider a bite guard. Constant grinding of teeth is dangerous for fillings and crowns, as well as natural teeth. It can cause serious joint inflammation as well as headaches. Luckily, bite guards can be worn night or day (depending on what you need), and are a great way to prevent further grinding.

Finally, there’s teeth whitening. It’s not uncommon for patients to want to brighten their smile, and the best way to do it by far is with in-office tooth whitening. There are many DIY options out there, of course, but in-office whitening has greater benefits.

When the whitening gel is applied to your teeth, we make sure your gums are protected. The results are generally faster and last longer with this approach, as well. Other methods may work, but they typically don’t last as long; sometimes they may not fully whiten all areas of your teeth.

No treatment is as easy and free of challenges as it seems. You still have to care for implants like regular teeth, which means no skimping on brushing and flossing just because they’re fake. Bite guards must be worn regularly to be effective. They also must be customized for your teeth; otherwise, they can be uncomfortable.

Whitening may cause temporary sensitivity in some mouths. For others, genetics may prevent you from achieving the precise shade you want.

If you have additional questions, feel free to call our Marysville, WA office. Our team is here to help you achieve your best possible smile!
