There are lots of ads out there for toothpastes that claim to repair damaged tooth enamel.

Can you treat cavities and tooth decay at home? Well, mostly, no, you can’t.

Can you strengthen your enamel at home? Very possibly—in some circumstances. Let us explain!

Cavities and tooth decay start forming when the enamel on the tooth’s surface breaks down. To discover what causes this breakdown, we need to see how chemistry works with our biology.

Tooth enamel is mainly made from calcium and phosphate ions. These minerals combine to form hydroxyapatite, crystals which make up around 95% of our enamel. Hydroxyapatite crystals are so strong that tooth enamel is the hardest part of our bodies. What can weaken a substance this strong?

Acids. Acidic foods and drinks, as well as acids created by the bacteria in plaque, strip away calcium and phosphate ions in enamel, weakening the surface of the tooth. This is a process called demineralization, and it’s the first stage of tooth decay. Left alone, weak spots will become bigger and deeper until they form cavities.

And tooth enamel, unlike the rest of your body, isn’t living tissue. It can’t regenerate. Once bacteria and acids have created a deep enough cavity, only Drs. Rottschalk, Acker, and Froidcoeur can repair it by removing decay and filling the tooth.

Wait, this sounds a lot more like “No, you can’t repair your enamel” and much less like “It’s possible to strengthen your enamel.” But we’re not through!

Demineralization doesn’t equal cavities—yet. Careful attention to your habits and your diet can make a difference in whether your enamel continues to weaken or becomes stronger.

Our body’s first defense against demineralization is saliva. Calcium and phosphate ions in saliva bathe the teeth throughout the day, restoring the minerals which have been lost. This is called remineralization. Saliva also helps neutralize acids from the foods we eat. But with a diet heavy in acids, or a lot of plaque buildup, saliva just can’t keep up with the damage.

That’s where “enamel-repair” toothpastes come in. Toothpastes are available that contain hydroxyapatite to restore calcium and phosphates to weakened enamel. But for many of the most common enamel-repair toothpastes, the not-so-secret secret to their effectiveness is fluoride.

Dentists recommend fluoride toothpastes for several very good reasons. Fluoride is attracted to the minerals in tooth enamel and bonds with them. Once bonded, fluoride attracts the calcium and phosphate ions in saliva, helping restore lost minerals to the enamel. Even better, when fluoride bonds with the calcium and phosphate in our enamel, fluorapatite is created. This is a crystal even stronger and more acid-resistant than hydroxyapatite.

If you’re concerned about the strength of your enamel, and especially if you notice any signs of acidic erosion, talk to our Fairview Heights, IL dental team right away. Drs. Rottschalk, Acker, and Froidcoeur can:

• Recommend over-the-counter toothpastes or professional fluoride applications to help reverse early demineralization
• Provide dental bonding, a crown, or a veneer to protect a tooth with serious erosion
• Treat a cavity caused by more advanced tooth decay.

Keeping your enamel healthy at home can take many forms. By careful brushing and flossing to remove plaque, by watching the acids in your diet, by making sure you’re properly hydrated, and by using fluoride toothpaste, you can both reduce the risk of demineralization and help restore weak spots in your tooth enamel.

So, can enamel-repair toothpastes effectively repair your teeth? Yes, they can be effective—if demineralization is in its early stages and if you make them a regular part of your daily dental routine.

Fluoride is a mineral that plays an essential role in oral health. In fact, the significant reduction in American tooth decay in recent decades can be attributed to a greater availability of fluoride in public water supplies, toothpaste, and other resources. When it comes in contact with the teeth, fluoride helps protect the enamel from acid and plaque bacteria. In some cases, it can even reverse tooth decay in its earliest stages.

Despite the benefits of fluoride, tooth decay is still common, especially among teenagers. The Centers for Disease Control reports that cavities can be found in more than half of young teens and two-thirds of older teens over age 16. Many of those teens are deficient in fluoride, either due to a lack of public water fluoridation or the use of bottled water. So how can parents ensure their teens are getting the fluoride they need to facilitate strong, healthy teeth?

Monitor Fluoride Exposure

Drs. Rottschalk, Acker, and Froidcoeur and our team at Dr. John Rottschalk Dental Group recommend you start by measuring your teen’s fluoride exposure. Make sure you purchase fluoridated toothpaste for your household, and find out if your tap water is fluoridated. If your teen primarily consumes bottled water, examine the bottle to determine whether fluoride has been added. The majority of bottled waters are not supplemented with fluoride, but those that are will be clearly labeled.

Fluoride Supplementation

Drs. Rottschalk, Acker, and Froidcoeur may recommend topical fluoride treatments at routine dental exams. These treatments are painless for your teen and may help establish stronger enamel that is more resistant to plaque and tooth decay. If you have a public water supply that is non-fluoridated, we may recommend fluoride supplementation between visits. These can be administered as drops, tablets, or vitamins.

Keep in mind that fluoride is most important for children and teens under the age of 16. Be proactive about your teen’s oral health by speaking with us about your family’s fluoride needs at your next dental visit.

We want our children to have every advantage, including oral health. That’s why you encourage your child to brush twice a day. You keep the sugary treats to a minimum. You schedule dental exams and cleanings at our Fairview Heights, IL office.

So, how did your child get a cavity? What to do to prevent more tooth decay?

First, don’t feel guilty. Some people are more prone to cavities, even with diligent brushing and flossing. But to make sure children have all the advantages when it comes to preventing cavities, we have some tips which might improve their dental habits.

• Better Brushing

Even for adults, brushing technique can be haphazard! Brushing’s not as effective without covering all the tooth surfaces (inside, outside, and molar tops), holding the brush at a 45° angle, gently brushing the teeth with small strokes, brushing for at least two minutes, and flossing between the teeth at least once a day.

Until children develop the motor skills to brush by themselves (around age six or seven), you can help by monitoring their brushing and flossing. If you like, you can use these four minutes a day for fun as well as dental care by playing music, awarding stickers, using an app with entertaining timers, or having your child mirror your brushing habits as you brush together.

And do make your child’s life easier with the right tools. Brush heads should be small enough to fit in little mouths comfortably, and bristles should always be soft. Floss, too, should be soft and flexible. Don’t forget to retire your child’s brush after three or four months—bristles start to fray and won’t clean effectively.

• Sealing the Deal

Ask about dental sealants. This treatment provides a protective coating for your child’s molars. Cavities are so common in molars because the tops of these teeth are quite uneven. Food particles and plaque are trapped in grooves where brushes have a hard time reaching.

The sealant process is a simple and safe one. Healthy teeth are cleaned and dried, an etching solution prepares the tooth surface, a thin coat of sealant is applied, and the coating is hardened under a curing light.

Drs. Rottschalk, Acker, and Froidcoeur might recommend sealants when your child’s first adult molars erupt. Enamel takes a while to develop its full strength, so new molars are especially vulnerable to cavities. Sealants typically last from three to five years, and studies have shown a dramatic reduction in cavities when teeth are treated with sealants.

• Fluoride Helps Prevent Cavities—in Two Ways!

Fluoride helps strengthen enamel in developing teeth. Because many communities have fluoride available in their water systems, your child gets the benefit of this natural mineral.

If you’re providing your child with fluoride toothpaste, you’re helping prevent cavities in the teeth, which have already erupted. The acids from oral bacteria weaken the mineral structure of enamel, which is the first step in forming a cavity. Fluoride helps repair weakened enamel in a process known as “remineralization.”

Drs. Rottschalk, Acker, and Froidcoeur can let you know the amount of fluoride that is right for your child, including how much or how little fluoride toothpaste to use, a prescription supplement if your water doesn’t contain fluoride, or the application of a fluoride treatment directly to your child’s teeth.

• Avoid Tricky Treats

Some treats are much better than others. We’re not talking taste, though. When it comes to dental health, texture and time are more important.

When your child enjoys a plain chocolate bar, saliva helps wash away sugary food particles. Sticky candies and starches, like caramels and potato chips, are a “stickier” problem. They cling to enamel, providing lots of sugar as fuel for cavity-creating bacteria. Similarly, drinking a soda with lunch (not every day, of course!) provides a short exposure to sugars. Sipping sodas throughout the day is like bathing teeth in sugar for hours at a time.

To eliminate some of the treats bacteria love, choose snacks with an eye to how they affect teeth throughout the day, and teach your child to brush or rinse with water after eating.

• Schedule Regular Dental Exams and Cleanings

Most children should be visiting Dr. John Rottschalk Dental Group twice a year, even during the baby teeth years. Drs. Rottschalk, Acker, and Froidcoeur will monitor your child’s primary teeth and developing teeth and bite. And a professional cleaning removes built up plaque that even the most dedicated brusher might miss.

If you have any concerns about cavities and their prevention, Drs. Rottschalk, Acker, and Froidcoeur will have suggestions tailored to your child’s individual needs. Us working together to make sure your child has a healthy, confident smile? That’s a partnership that will provide lifelong advantages!

Quick trivia question: define “mamelon.” Some kind of warm blooded animal? No, not a member of the mammal clan, but good guess. A fruit of the gourd family? Nope! There are watermelons, and honeydew melons, and even canary melons, but no ma-melons. Those little rounded bumps you notice on the edge of your child’s permanent incisors when they first emerge? We have a winning answer!

• Why Do We Have Mamelons?

We have eight incisors, or biting teeth, in the front of our mouths—four on top and four on bottom. Mamelons are actually a clue as to how these incisors were formed. Even before a baby is born, the permanent teeth begin to take shape. Three different groups of cells develop to form the incisal edge of these front teeth. As they fuse together, they create three lobes of enamel on the erupting edge of the tooth. It’s these lobes, or bumps, that give the teeth a serrated appearance.

Whether your child’s mamelons are quite prominent or barely noticeable, if you are worried about them, relax! They are almost always a temporary part of your child’s smile, and disappear over time with chewing and normal wear. But what if the mamelons overstay their welcome?

• Cosmetic Concerns

Because mamelons are composed of enamel, without the underlying dentin layer found in the body of the tooth, they can appear translucent or a bit different in color. They might wear away unevenly, leaving the tooth edges looking misaligned. Or, they might not wear away at all if your child’s tooth eruption is delayed. Talk to Drs. Rottschalk, Acker, and Froidcoeur if mamelons are a cosmetic concern for you or your child. You might discover that they are wearing away naturally, or we can discuss ways to polish or smooth them down if needed. This is a painless procedure that doesn’t require an anesthetic. Generally, however, this is a matter where time will resolve the issue for you.

• Orthodontic Implications

Occasionally, mamelons might become a topic of discussion for orthodontic reasons. Sometimes, mamelons do not wear away over time because of a malocclusion (misaligned bite). Your orthodontist will let you know your child has a bite problem and can explain treatment options. Your orthodontist might also suggest smoothing away the mamelons to ensure that the edges of the incisors align correctly and symmetrically while the teeth are in the process of straightening. Again, this is not always considered a necessity, so weigh your options with your dental care provider.

So, if you notice that your child’s beautiful new teeth are bumpy or serrated as they erupt, don’t be concerned! If you have any questions about mamelons, talk to Drs. Rottschalk, Acker, and Froidcoeur at your next visit to our Fairview Heights, IL office. This is a natural occurrence and most likely just a temporary “bump” in the road. Soon enough, mamelons will be a memory—and the answer to a pretty difficult trivia question.
