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. Coombs, Holmes, and Johnson might discover an unexpected cavity at a regularly scheduled dental exam at our Spokane, WA 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. Coombs, Holmes, and Johnson 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. Coombs, Holmes, and Johnson 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 Spokane, WA 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.

Millions of people, around Spokane, WA and beyond, wear green on St. Patrick’s Day so they can show their spirit for the holiday and avoid getting pinched. While it may be easy for you to throw on a green shirt, sport a St. Patrick’s Day button, or wear a pair of emerald-hued shoes, if you’re an avid St. Patty’s Day enthusiast you may want to try something different this year. Drs. Coombs, Holmes, and Johnson thought of a few ideas that will help you take your holiday spirit to the next level:

Visit Chicago’s Green River

If you happen to be near the Windy City during St. Patrick’s Day or you’re thinking of planning a trip, don’t miss out on going downtown to watch the large-scale celebration that kicks off when the city dyes the river bright green. According to the Chicago Sun-Times, Chicago has been celebrating the holiday with this tradition for more than 50 years, with tens of thousands of people gathering annually to witness the mysterious dying process and the stunning result.

Don Green Face Paint

Just like an avid sports fan on game day, you can use green face paints to showcase your enthusiasm for this holiday. Avoid breakouts or allergic reactions by only using paints that are specifically meant to be applied to the skin. A little bit of face paint can cover a large area, so feel free to get creative and decorate the whole family on St. Patrick’s Day.

Eat Green All Day

Not a fan of green eggs and ham? With the increasing popularity of green smoothies, there’s no better time to get in on this health craze. To create a green smoothie without the aid of food coloring, you can simply blend a generous amount of a leafy green vegetable, such as spinach or kale, with the ingredients that you would typically use to make a smoothie, like fruit, ice, milk, or juice. Keep the trend going throughout the day by using those same vegetables to create a green soup, egg salad, or a batch of bright green pastries. As an added bonus, you’ll get a healthy dose of vitamins without changing the taste of most of these foods.

If your old holiday routine has gotten stale, leave your green T-shirt in the drawer and try one or all of these tips. Don’t be surprised if you have so much fun that you decide to start a new, annual St. Patrick’s Day tradition! Have a happy St. Paddy’s day from South Hill Pediatric Dentistry!

While you don’t have to wait to start eating right, March is the month the Academy of Nutrition and Dietetics asks everyone to pay special attention to what goes into our bodies. The Academy has designated the month of March for focusing the public’s awareness on what they eat.

What Not to Eat

The academy points out that the foods you eat have a direct effect on the health of your teeth and specifically on tooth decay. Bacteria rely on carbohydrates to thrive. That is why Drs. Coombs, Holmes, and Johnson and our team at South Hill Pediatric Dentistry tell our patients to cut back on both candy and sweets. They consist of simple sugars that feed the bacteria in your mouth and enhance tooth decay.

It’s the hidden sugars that will cost you, though. Get in the habit of reading labels on food and looking for products with added sugar. This includes ingredients that end with the suffix “ose.” When it comes to nutrition, these foods offer little value beyond satisfying that sweet tooth.

What You Should Eat

Turn to foods that not only taste good but are good for your teeth too. Dairy products, for example, provide the body with nutritional items that support tooth enamel. Foods high in protein feature phosphorus, a nutrient critical to oral health.

You can’t really go wrong by adding color to your diet, either. Fruits and vegetables make for a colorful plate and a healthy meal. Use some caution with acidic fruits like oranges or even tomatoes, because the acid can erode tooth enamel. It is better to include these foods in a meal instead of eating them by themselves.

Remember, good nutrition is something you should worry about all year long, not just when celebrating National Nutrition Month. March just serves as a fun reminder that eating right is a proactive step in managing your dental health.

Scientists have discovered tooth decay in specimens that are more than 15,000 years old. The ancients once thought that cavities were caused by something called “tooth worms” … Eew! They didn’t exist, of course, but how else could humans explain the holes that cavities make in teeth?

The appearance of cavities on a widespread basis is often traced to the rise of farming. The new diet filled with grains and carbs made our mouths a haven for cavity-causing bacteria. As we added more sugar to our diets, our teeth got worse.

The “tooth worm” idea didn’t completely disappear until the 1700s when scientists finally began to understand the process of dental caries. Once that part of the puzzle was solved, they began focusing on filling existing cavities and preventing new ones.

Dental Fillings Come of Age

Many different materials, including beeswax, cork, aluminum, tin, and even asbestos, have been used to fill the holes caused by dental decay. Sometime in the mid-1800s, however, dentists began to use metal fillings such as gold, platinum, silver and lead amalgams.

The amalgam we use today is mixed from liquid mercury, silver, tin, copper, zinc, and other metals, but some patients still like the look of a gold filling. Newer options include composite-resin fillings, which are made from a tooth-colored mixture of plastic resin and finely ground glass-like or quartz particles that form a durable and discreet filling. Porcelain or ceramic fillings are natural in color, but more resistant to staining.

Drs. Coombs, Holmes, and Johnson can help decide which filling is best for you, based on cost as well as your dental and lifestyle needs. You may not have “tooth worms,” but if you have cavities, contact our Spokane, WA office so we can take the proper action to protect the health of your mouth.
