If you love ice cream, then you'll get a kick out of this: Your favorite treat has its own month. That's right, July is National Ice Cream Month, when we celebrate—and indulge in—one of the most delicious concoctions ever known. Just don't overdo it, among other reasons, for the sake of your teeth.
In a way, it's a bit of a love-hate relationship between this frozen wonderfulness and your dental health. Like any dairy, ice cream is full of nutrients like calcium, phosphorous and vitamin D that together strengthen tooth enamel and help prevent decay. But this nutritional benefit is tempered in most ice cream by its other major ingredient: sugar.
Sugar can be a problem for your teeth because disease-causing oral bacteria love it just as much as you do. It's a prime food source for them, and when there's a lot available (like right after you finish that dipped cone) bacteria go crazy multiplying and producing acid. This could lead to tooth decay or gum disease.
Sugar's effect on dental health is an issue not only with ice cream but with other desserts and sweetened snacks as well. What can you do, then, to have your ice cream (or cake) and your dental health too?
Moderate your consumption. We're not saying you have to give up sweet desserts like ice cream—just keep your portions small and infrequent. Partake of them mainly as an occasional treat rather than as standard everyday fare.
Brush after eating. The biggest threat to dental health is the sugar that lingers in the mouth after we eat something sweet like ice cream. So, wash your mouth out with water and then brush your teeth after eating to remove any residual sugar. But not right away—give your saliva a chance to neutralize any mouth acid first by waiting about thirty minutes.
Choose healthier options. Instead of diving into a bowl of butter pecan or rocky road when you get the urge to snack, try a little non-fat Greek yogurt or cheese with some fresh fruit. Choosing alternatives like these can still give you the benefit of dairy without the excess sugar.
Ice cream is one of those indulgent little pleasures that make life sweet. Just be sure you're enjoying it within healthy limits to protect your dental health.

What and how you eat and drink has a significant impact on the health of your teeth and gums. Therefore, an effective oral hygiene regime must take your diet into account.
Acid is your teeth's enemy; it can erode their protective enamel coating (a process called demineralization). Certain foods and beverages (such as citrus drinks and coffee) contain it, and it's produced by bacteria in your mouth that feed on dietary sugar and release acid as a byproduct (a process called fermentation). Your allies are foods and beverages that neutralize acids, provide minerals and vitamins to repair tooth enamel, and stimulate saliva.
Sugar & Decay
Sugars, the leading promoter of dental decay, exist in many forms in our diet. Some occur naturally, while others — referred to as “free sugars” — are added by the manufacturer, cook or consumer. The latter are most often linked with decay. Soft drinks are the primary source of dietary free-sugars in the U.S.
Sugars in fruit, vegetables, milk and unprocessed, starch-rich foods such as rice, potatoes and whole grains, do not appear to be harmful to teeth. Note, however, that dried fruits contain a highly concentrated sugar level and can stick to tooth surfaces. The sugar substitutes xylitol and sorbitol appear not to promote decay. In fact, there's evidence that chewing xylitol-sweetened gum three to five times daily for at least five minutes (after meals) stimulates saliva flow, which helps protect against decay.
Acids & Erosion
In addition to eroding tooth enamel, acidic foods and beverages create an environment where it's easier for decay-promoting bacteria to flourish. Saliva can reduce acidity but it must have time to work, at least 30–60 minutes. That's why behaviors that maintain acid levels, such as sipping coffee throughout the day, can be harmful.
Saliva is a front-line defense against erosion and decay. It helps remove food particles and contains minerals that help neutralize acid and promote remineralization of the tooth surface. Foods that stimulate saliva and/or contribute essential minerals include:
- Cheese — stimulates saliva and is rich in calcium, contributing to the re-calcification of teeth and protecting against the loss of calcium,
- Cow's milk — contains decay-counteracting calcium, phosphorous and casein,
- Plant foods — are fibrous and require chewing, which mechanically stimulates saliva,
- Water — keeps you hydrated, which is important for saliva production and preventing dry mouth (a condition that promotes acid-producing bacteria), and helps wash away food particles; fluorinated water bestows the protective properties of fluoride (a compound that makes tooth enamel more resistant to acid erosion and promotes re-calcification).
As you can see, brushing and flossing effectively is just part of the oral hygiene equation.

You probably know that tooth decay results when the bacteria in your mouth release acids after consuming sugars. After you eat sugars, particularly the type of sugar known as sucrose, increased acid in your mouth begins to dissolve the enamel and dentin in your teeth, and you end up with cavities.
What are the Types of Sugars?
Modern diets include several types of sugars. Most of these are fermented by oral bacteria, producing acids that are harmful to teeth.
- Sucrose (commonly known as sugar)
- Glucose (released from starch consumption)
- Lactose (milk sugar) — Less acid is produced from this type of sugar
- Fructose (found naturally in fruit and also added to many processed foods)
Recommended intake of “free sugars” is no more than 10 teaspoons per day. Note that a can of soda contains over 6 teaspoons! Soft drinks are the largest source of sugar consumption in the U.S. In 2003, for example, Americans drank an average of 52 gallons of soft drinks. Average per capita consumption of all sugars in the U.S. was 141.5 pounds (64.3 kg) one of the highest levels in the world.
Sugar substitute xylitol (which is chemically similar to sugar but does not cause decay) can be part of a preventive program to reduce or control tooth decay. Chewing gum sweetened with xylitol stimulates saliva flow and helps protect against decay.
Sugars Released from Starches
Starches are foods like rice, potatoes, or bread. When you eat refined starches, such as white bread and rice, enzymes in your saliva release glucose. However, these foods have a lower potential to produce decay than foods with added sugars. When sugars are added to starchy foods, as in baked products and breakfast cereals, the potential for decay increases.
Less refined starches such as whole grains require more chewing and stimulate secretion of saliva, which protects from harmful acids.
The Case for Fruit
Fresh fruit has not been shown to produce cavities, so it makes sense to eat them instead of sugary desserts and snacks. Dried fruit is more of a problem because the drying process releases free sugars.
