While they may sound refreshing, especially after participating in sports activities or after a jog, recent studies suggest that energy and sports drinks can damage tooth enamel, thus elevating your cavity risk. These drinks are especially popular among our younger patients.

In the study, researchers analyzed the fluoride content and pH levels of 13 sports and nine energy drinks by soaking tooth enamel samples in the aforementioned drinks. The samples were soaked for 15 minutes in each drink, and then were soaked for two hours in artificial saliva four times a day for five days.

As much as sports drinks are harmful to your teeth, researchers found that exposure to energy drinks such as Rockstar, Monster®, and Red Bull® resulted in twice as much enamel loss as exposure to sports drinks such as Powerade®, Gatorade®, and Propel® (3.1 percent to 1.5 percent).

Yes, there are health benefits to consuming orange juice, fruit juices, sports drinks, and flavored waters, which can contain valuable ingredients such as vitamin C and other antioxidants; these drinks can also replenish nutrients lost during a sporting event and lower the chance of heart disease and cancer. But, if not consumed carefully, these beverages can harm your teeth. They are full of sugar, which converts to acid and wears away at your teeth, causing cavities, sensitivity, and eventually tooth loss.

Even one drink a day is potentially harmful, but if you are absolutely unable to give up that sports or energy drink habit, we encourage you to minimize their use and rinse with water afterward or chew a sugar-free piece of gum. Do not brush immediately after drinking them; softened enamel due to acid is easier to damage, even when brushing. Remember, it takes your mouth approximately 30 minutes to bring its pH level back to normal. The best thing to do is to wait an hour, then brush to remove sugar that lingers on your teeth and gums.

There are many sports drinks, energy drinks, and flavored waters out there today. Dr. Daniel Ma and our team recommend you take the time to read the labels. Check for sugar content and citric acid in the ingredients. If you have any questions, or would like suggestions on the best sports drink options, please give us a call at our Vancouver, BC office or ask us during your next visit!

Many people who are careful about brushing and flossing their teeth wonder how they still end up with cavities or tooth decay. Several factors affect wear and tear on tooth enamel. Diet is a major factor, with certain foods increasing the likelihood that your enamel will become discolored or decayed. Pay close attention to the foods you eat to keep your pearly whites looking healthy and clean.

What causes enamel damage?

Tooth enamel refers to the hard, semi-translucent, whitish part of the tooth that shows above your gums. The enamel is primarily composed of minerals that are strong but susceptible to highly acidic foods. When acid reacts with the minerals in enamel, it results in tooth decay. Strongly pigmented foods can also damage enamel by discoloring the surface of the tooth.

Foods that harm enamel

Acidic foods are the greatest source of enamel damage. To determine whether a food is acidic, look up its pH. Scientists use pH, on a one-to-seven scale, to define the relative acidity or alkalinity of a substance. Foods with low pH levels, between a one and three, are high in acidity and may damage your enamel. Foods with high pH levels, such as a six or seven, are far less likely to cause enamel harm.

So which foods should you avoid? Many fruits are high in acidity, including lemons, grapefruit, strawberries, grapes, and apples. The high sugar and acid content in soda makes it another huge contributor to enamel decay. Moderately acidic foods include pineapple, oranges, tomatoes, cottage cheese, maple syrup, yogurt, raisins, pickles, and honey. The foods that are least likely to cause enamel damage include milk, most cheeses, eggs, and water.

Beverages such as red wine and coffee also damage the enamel by discoloring it. Although stains do not necessarily undermine the integrity of your teeth, they can be unsightly.

What can I do to prevent enamel damage?

Fortunately, there are several measures you can take to prevent your enamel from discoloring or decaying. The easiest way to avoid decay is to steer clear of high-acidity foods. This may not always be possible, but eliminating sugary fruit juices and soda from your diet is a good start. Brushing your teeth after each meal and flossing frequently also preserves your enamel. Another good idea is to rinse your mouth with water or mouthwash after eating to wash away high-acidity particles.

Although enamel damage is common, it does not have to be an inevitable occurrence. Knowing the foods that harm your teeth gives you the tools to prevent discoloration and decay. With some easy preventive measures, your teeth will stay strong and white for years to come! Give us a call at our office to learn more!

It's almost game day and you're wondering what to put on the menu for your guests. Most snacks are typically highly processed and unhealthy. Why not mix it up this year and opt for some snacks that promote good oral health? Here are some of Dr. Daniel Ma favorites!

• Apples, carrots, celery, and cucumbers: These foods and other crispy, fibrous, fruits and vegetables are an excellent choice for the big game. Not only are they rich in vitamins and minerals which your body and mouth need, they are also known as detergent foods because of the cleaning effect they have on the teeth and gums. Try apples wedges spread with peanut butter and sprinkled with cinnamon.
• Beans: Beans are filling because they are packed with fiber and that keeps you from opting for sugary or fatty snacks. Along with fruits and vegetables, beans should be one of the stars of your game-day snack lineup. How about some hearty chickpea hummus with cucumber chips?
• Nuts like almonds, walnuts, pistachios, and cashews: Nuts abound in the minerals that help keep your teeth and gums strong like calcium, magnesium, and potassium. Put out a bowl of raw or roasted nuts for your guests as a crunchy, satisfying alternative to chips or crackers. Recent research even shows that the polyunsaturated fatty acids in nuts may help prevent gum disease. But remember not to eat the whole bowl! Nuts are very high in calories and a little goes a long way. Enjoy and handful or two along with your other healthy snacks.
• Dark chocolate: This one may be hard to believe at first, but research shows chocolate can be great for your teeth and help prevent decay! Now don't run off and start stocking your pantry with a bunch of that super sweet stuff, because these benefits come mainly from the tannins, polyphenols, and flavonoids present in the cacao bean. Dark chocolate is the least processed variety of chocolate and the closest to the cacao bean, so make sure you purchase a variety that is listed as 70% cocoa or more for these benefits. Like with nuts, chocolate is easy to overdo — aim to eat two or three squares.
