Is this a trick question? After all, you and your family probably already know quite a lot about cavities:

• It all begins when bacteria-filled plaque sticks to teeth and starts to attack enamel. How?
• Because the bacteria in plaque use the sugars and other foods we eat to produce acids.
• These acids gradually weaken teeth by dissolving minerals that help make up our enamel (a process called demineralization).
• Over time, a hole, or cavity, develops in the tooth surface.
• Left untreated, bacterial decay can spread to the inside of the tooth, creating a more serious cavity.

Drs. Hutcheson, Train, Goodall, Lewis might discover an unexpected cavity at a regularly scheduled dental exam at our Richardson or Carrollton office, but there are also some symptoms that should have you calling for an appointment. A cavity can cause sensitivity when eating something hot or cold, or it can be painful, or you might even notice visible discoloration or damage to the tooth surface.

So, if your child has any of these symptoms, it’s a cavity, right? It might be—but it might not. Sometimes, because the symptoms are similar, what we suspect is a cavity is really enamel erosion.

The bacteria-created acids weaken enamel. But it’s not just bacteria that subject our teeth to acids. Acidic foods are one of the leading causes of tooth erosion.

And while we expect damage from a lifetime of acidic foods and beverages to catch up with us as we age, the fact is that erosion is becoming a problem even for young children. How is this possible? Let’s look at some food chemistry.

Our normal saliva pH level is around a 7, which is neutral. Any number lower is acidic; any number higher is alkaline. Acidic foods have a low pH (the pH of lemon juice, for example, measures between 2 and 3), and can reduce our normal, neutral pH level. When saliva pH levels drop to 5.5 or lower, tooth enamel starts to demineralize, just as it does when exposed to the acids from oral bacteria.

Regularly snacking on citrus and other acidic fruits, fruit juices, flavored drinks, sour candies, and other acidic foods can cause enamel erosion. Especially erosive are sports drinks, energy drinks, and colas, because they contain some combination of citric acid, phosphoric acid and/or carbonation.

So, when might you suspect enamel erosion? Your child might be sensitive to hot or cold foods, or feel pain, or even have noticeable enamel loss or pitting. Even though these symptoms may not have been caused by plaque and bacteria, acidic erosion from our diets leaves weakened enamel just as vulnerable to cavities and decay.

How to avoid erosion?

• Serve acidic foods sparingly, or as part of a meal. This helps our saliva pH stay in the neutral zone.
• Balance acidic foods with low-acid choices to neutralize acids and restore a normal pH balance. For example, mix those acidic berries with a banana.
• Use a straw! These are not only fun, but this simple solution keeps erosive drinks from bathing young teeth in acids.
• Encourage your child to drink water instead of an acidic beverage, or drink it afterward to rinse acids away. The pH of pure water? A perfect, neutral 7. And by using tap water instead of bottled water, you’ll be providing fluoride, which helps strengthen enamel.
• What about brushing right after eating or drinking something acidic? Ask Drs. Hutcheson, Train, Goodall, Lewis if your child should rush for the brush. We may recommend waiting 30 minutes or so after an acidic treat to give the teeth time to remineralize. Otherwise, brushing might cause more wear and tear on enamel.
• Finally, while foods are often the source of acid erosion, medical conditions can cause erosion as well. Talk to us about ways to minimize erosion while addressing these medical needs.

Be proactive. Ask your Drs. Hutcheson, Train, Goodall, Lewis about healthy drinks and snacks for healthy teeth. Make sure to keep on top of brushing and flossing, and stick with fluoride toothpastes. And visit our Richardson or Carrollton office regularly for exams and cleanings.

There’s really no trick to it—preventing enamel erosion helps keep your child’s teeth structurally strong and cavity-free for a lifetime of beautiful and healthy adult smiles.

As a parent, you want the best for your children, and that includes doing their best in school. You can support them by taking an interest in their activities, being enthusiastic about attendance, and helping them with homework. There may also be one more way you can help your children succeed at school. Surprisingly, research suggests that children with better oral health are likely to do better in school.

What the Research Says

One study in North Carolina looked at risk factors for poor school performance among school-aged children. As expected, the study found poor school performance linked to low socioeconomic status, low levels of parental education, and poor overall health. However, it also found a strong link between poor oral health and poor school performance, with children classified as having poor oral health 40 percent more likely struggle in school.

These findings are generalizable to the rest of the country. For example, attendance is an important factor in academic achievement, but dental conditions are responsible for a loss 51 million school hours among schoolchildren each year. Dental pain and infection are linked to poorer performance.

School-Based Programs to Promote Oral Health

In light of the apparent benefits of good oral health for school performance, some schools are taking steps to promote better oral care and health. In Maine, for instance, schools in need can apply for grants through School Oral Health Program (SOHP). The SOHP consists of four components:

1. Oral health education for all children to support healthy behaviors
2. A weekly fluoride mouth rinse to strengthen teeth
3. Dental screenings to identify children who may need dental care
4. Dental sealants, or plastic coatings, on back teeth to guard against decay

The State of Maine also supports an “Annual Sugar Out Day” to raise awareness of the effects of sugar on dental health and to help students choose low-sugar alternatives.

Oral Health Habits to Adopt

You can help your child improve oral health and do better in school by encouraging good oral hygiene. This includes brushing at least twice a day with a fluoride-containing toothpaste, and reminding your child to drink water after eating. Also, regular trips to our Richardson or Carrollton office can help prevent serious tooth problems.

It seems like sharks are everywhere these days—on land, sea, and air(waves). A halftime show meme gone viral. A week of summer TV devoted to our favorite apex predators. And who doesn’t have “Baby Shark” playing in their heads all day once they’ve heard it? But are we jumping the shark to discuss this topic in a dental blog?

Not at all! Because today, we’re going to talk about shark teeth—just not the ones you might be expecting.

One of the expected sights when a shark opens its mouth are those rows and rows of shiny shark teeth. Sharks can grow from two to 15 rows of teeth at any one time (and some sharks have even more). This means sharp new teeth are always ready to replace any shark tooth which is lost, broken, or worn out.

An unexpected sight? When children point to their new adult tooth or teeth coming in—right behind their still-firmly rooted baby teeth! This double set of teeth is called “shark teeth,” and, while it certainly might come as a surprise, it’s not all that uncommon. But why do children develop shark teeth at all?

After all, baby, or primary, teeth have small roots, and are designed to come out easily when the adult teeth start arriving. When a permanent tooth starts to erupt, it pushes against the root of the baby tooth above it. This pressure gradually dissolves the root of the primary tooth, and with nothing to anchor it, it’s now loose, wiggly, and ready to fall out. That’s why baby teeth often look like they have no roots at all when they eventually wiggle free.

Sometimes, though, the roots of a primary tooth don’t break down, which means baby teeth stay right where they are. It also means that the permanent teeth have to erupt somewhere else—usually behind those stubborn little baby teeth.

Shark teeth can first appear around the ages of five to seven when the permanent front teeth start arriving, or several years later, when the adult molars begin to come in. Any extra teeth in one small jaw naturally cause concerns about crowding and misalignment, especially when those extra teeth are molars. Fortunately, treatment is generally uncomplicated.

If the baby tooth is loose, time (and wiggling) might take care of the problem. But if the primary tooth or teeth just won’t budge, even after several weeks, it’s a good idea to schedule a visit with Drs. Hutcheson, Train, Goodall, Lewis—especially if your child is experiencing pain or discomfort.

An extraction is often suggested when a baby tooth has overstayed its welcome. Because of its smaller root, extracting a primary tooth is usually a straightforward procedure. Drs. Hutcheson, Train, Goodall, Lewis can let you know all the details, and can discuss sedation options if they’re appropriate for your child.

Whether baby teeth are left to fall out on their own, or given some assistance, most often your child’s permanent tooth will start moving to its proper position as soon as the space is available.

Unlike sharks, we don’t have an endless supply of replacement teeth, so it’s understandable to worry when you see anything unexpected. If you want to know more about shark teeth, or if you have any concerns, don’t hesitate to call our Richardson or Carrollton office for expert advice.
