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. Melissa Dennison Newman 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. Melissa Dennison Newman, though! Through regular checkups and cleanings at our Plaistow, New Hampshire 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!

Hand-foot-and-mouth disease, or HFMD, is a type of contagious viral illness that causes a rash in the mouth and on the hands and feet of infants and young children, and, while rare, adults. Characterized by sores in the mouth and a rash on the hands and feet, hand-foot-and-mouth disease is most commonly caused by a coxsackievirus, a bacterium that lives in the human digestive tract. HFMD can spread from person to person, typically via unwashed hands.

What are the symptoms of HFMD?

Symptoms of HFMD usually begin with a fever, sore throat, poor appetite, or general malaise. A couple of days after the fever starts, kids may develop painful sores in the mouth. A skin rash characterized by red spots may also develop, usually on the palms of your child’s hands and soles of their feet. It’s important to note some children may only experience a rash while others may only have mouth sores.

Is HFMD serious? Should we be concerned?

Usually not. Nearly all children infected recover anywhere between seven to ten days without medical treatment. Rarely, however, a child can develop viral meningitis and may need to be hospitalized. Other rare complications of HFMD can include encephalitis (brain inflammation), which can be fatal.

How can my child prevent HFMD?

There is no known vaccine to defend your child against HFMD. However, the risk of your child contracting the disease can be reduced by:

• Making sure your child washes his or her hands often
• Thoroughly cleaning objects and surfaces (these include doorknobs and toys)
• Making sure your child avoids close contact with those who are infected

Tooth decay affects everyone, with studies reporting that 92% of adults have had a cavity at one point in their lifetime. In more serious instances of tooth decay, however, the nerve of the tooth may become infected. This type of infection requires a root canal, in which the affected nerve is removed, and the interior of the tooth is cleaned and filled.

Tooth Anatomy

Although each tooth is covered by a hard outer shell, the interior of a tooth consists of dental pulp. This pulp is soft, containing blood vessels that bring nutrients to the tooth. Each tooth also has an associated nerve, which resides within a root canal passing from the tooth’s root into the dental pulp. This nerve provides information about temperature, allowing teeth to sense heat or cold.

Symptoms of Nerve Infection

Damage to the dental pulp or nerve tissue leads to a rapid multiplication of bacteria within the interior of the tooth. The result may be an abscess, a small pocket near the root of the tooth that becomes full of pus. This infected area commonly causes the following symptoms:

• Intense pain or sensitivity when pressure is applied to the tooth
• Sensitivity to hot or cold temperatures, even after the heat or cold has been removed
• Darkening or discoloration of the affected tooth
• A small, persistent pimple that forms on the gums
• Swollen or tender gums
• Swelling in other areas of the face, neck, or head

Nerve infection may occur due to deep decay, although repeated dental procedures, facial trauma, chipping or cracking of a tooth, or large fillings may also contribute to an abscessed tooth.

What to Do if You Think You Need a Root Canal

Only a visit to Dr. Melissa Dennison Newman can confirm whether a tooth’s nerve has become infected. We will perform an oral examination and X-rays to confirm whether the tooth is abscessed. If a root canal procedure is needed, a small hole will be placed in the tooth. The pulp and nerve tissue are removed from the tooth, which is thoroughly cleaned and filled. Then, the hole is sealed with a special compound to prevent bacteria from entering the tooth’s interior. The entire procedure is performed under local anesthesia to numb pain.

If you think you may have tooth or nerve decay, call our Plaistow, New Hampshire office today to schedule a diagnostic appointment.

Toothpastes come in many forms and boast different flavors, benefits, and endorsements. All are designed to remove surface bacteria and prevent the buildup of plaque that can cause tooth decay. With so many choices, Dr. Melissa Dennison Newman and our team at Highland Family Dental know that selecting the right toothpaste can be intimidating. After all, some benefits are welcome bonuses, while others are absolutely essential. So how can you know which toothpaste is best for you?

ADA Seal of Approval

While all toothpastes must first be approved by the Food and Drug Administration for sale to consumers, the American Dental Association puts these products through further rigorous tests for safety and effectiveness. Toothpaste that boasts the ADA Seal of Approval can be trusted to do exactly what it claims.

Fluoridated

Fluoride is an essential ingredient in a daily toothpaste. It helps to protect the tooth from decay by removing plaque and strengthening the enamel. Although fluoride is found in many public water supplies, many people are deficient in it due to the consumption of bottled water instead of tap water. All toothpastes with the ADA Seal of Approval contain fluoride.

Other benefits

If a toothpaste meets the ADA’s standards and contains fluoride, the next step is to clear it with your dentist. This is especially true if you decide to use a whitening toothpaste, which often contains abrasives to remove surface stains. Though abrasives are an effective aid in tooth whitening, they may not be recommended if you have weak tooth enamel.

Specialty toothpastes

In certain situations, Dr. Melissa Dennison Newman may suggest or prescribe specialty toothpaste, depending on your oral health needs. For example, patients who are prone to tooth decay and cavities despite frequent brushing and flossing may benefit from prescription-strength fluoridated toothpaste to help prevent the weakening of tooth enamel. Others who suffer from tooth sensitivity may benefit from the use of desensitizing toothpaste. Talk with Dr. Melissa Dennison Newman if you think a specialty toothpaste could be right for you by scheduling an appointment at our Plaistow, New Hampshire office.
