When Is a “Cavity” Not a Cavity?

November 8th, 2023

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.

Dr. Goodall might discover an unexpected cavity at a regularly scheduled dental exam at our Frisco 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 Dr. Goodall 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 Dr. Goodall 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 Frisco 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.

Fluoride Use in Adolescents

November 1st, 2023

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

Dr. Goodall and our team at More Than Smiles 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

Dr. Goodall 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.

Halloween: Candy, costumes, and more!

October 26th, 2023

All Hallows' Eve, more commonly known as Halloween, is a yearly event celebrated on October 31, and one that is anticipated by the young and young at heart all over the world. Some scholars claim that Halloween originated from Celtic festivals that honored the dead or that celebrated the harvest, while others doubt that there's any connection at all to Samhain (a Gaelic harvest festival.) Regardless of its origin, our team at the Pediatric Dentistry office of Dr. Goodall hopes that Halloween is fun and enjoyed by all of our awesome patients!

Trick or treat?

In North America, Halloween is predominantly celebrated by children who dress up in costumes, which range from scary to cute, who then go around the neighborhood knocking on doors asking "trick or treat", and they are given candy in return. Trick-or-treating is a time honored tradition, and though many parents groan at the pounds and pounds of candy collected by youngsters and fear for the health of their teeth, there are a few things you can do to help their teeth stay in great shape until the candy is gone:

  • Limit the amount of candy they can consume each day
  • Have them brush their teeth after eating candy
  • Avoid hard, chewy candies as they can stick in hard to brush places
  • Keep candy out of sight to reduce temptation
  • Don't buy candy too far in advance to limit pre-Halloween consumption
  • Help or encourage your children to floss

Halloween Fun

Halloween isn't just about gorging on candy; there are other events associated with this festive day including carving jack-o'-lanterns, painting pumpkins, decorating sugar cookies, bobbing for apples, going to haunted houses, or just curling up on the couch with a bowl full of popcorn and watching some classic, scary movies.

Halloween Around the World

Some countries, like Australia, frown upon Halloween, claiming it is an American event and not based in Australian culture, while others like Italy have embraced the fun and celebrate much as Canadians and Americans do. Mexicans have been celebrating this fun day since around 1960, and it marks the beginning of the Day of the Dead festival. Some countries in Europe have come late to the party, but since the 1990s, countries like Sweden, Norway, and Germany have started celebrating Halloween as well, and finding children in costumes or having ghosts hanging in windows has become commonplace.

Halloween is about fun; stepping outside our normal lives and donning a costume or gathering with friends to knock on doors and ask for candy is as much a part of our culture as hot dogs and barbecue on Labor Day. Have a safe and happy Halloween from the team at More Than Smiles!

How can I protect my child's teeth during sports?

October 18th, 2023

Sports are great for children for a variety of reasons. Children can develop their motor skills, learn how to solve conflicts and work together, and develop their work ethics. As a parent, you may recognize the benefits of sports, but also naturally worry about your child’s health and safety. Your job goes beyond providing a water bottle and making sure your child follows the rules of the game.

Although you may not think of your child’s teeth first when you think about sports, accidents can happen that affect your children’s teeth. A stray hockey stick, an errant basketball, or a misguided dive after a volleyball are examples of ways a child could lose a tooth. In fact, studies show that young athletes lose more than three million teeth each year.

Becoming a Better Athlete to Protect Teeth

Becoming a better athlete involves refining skills, learning the rules of the game, and being a good sport. These components are not just about winning. They are also about safety. Young athletes who are better ball-handlers and who are careful to avoid fouls and penalties are less likely to have harmful contact with the ball, teammates, or opponents. Children who are better roller-bladers are less likely to take a face plant into the blacktop, and more likely to save their teeth. Being a good sport and avoiding unnecessary contact is one way to protect teeth.

Proper Protective Equipment for Teeth

If your child is in a sport that poses a high threat to teeth, it is essential for your child to wear a mouthguard. Mouthguards fit your child’s mouth and consist of soft plastic. Dr. Goodall can custom fit a mouthguard if generic ones are uncomfortable. While children may resist wearing a mouthguard initially, your persistence in insisting that they wear it should be enough to convince them. A helmet or face mask provides additional protection.

While prevention is best, rapid treatment can improve the situation if your child does happen to lose a tooth during sports. Rapid implantation can work in about ten percent of cases. To learn about ways to save a lost tooth, contact our Frisco office.
