Acid and Tooth Enamel Erosion
As tough as your teeth are, they’re at risk when acid levels in your mouth get too high. Acid erodes enamel and causes decay. Certain foods and drinks, along with bacteria that live in your mouth, usually make most of the acid that damages teeth. Enamel can also wear away if you have a condition that brings a lot of stomach acid into your mouth, like acid reflux disease (also called GERD), bulimia, or alcoholism. It can also happen to pregnant women who vomit often.
What you can do: Work with your doctor to treat the condition that’s causing the acid problem. If you’re pregnant and throw up a lot, it might be a good time to get a dental checkup, which doctors usually recommend during pregnancy.
To protect your enamel, cut down on foods and drinks that have a lot of acid, like sodas and citrus fruits and juices. When you do have something acidic, rinse your mouth with water right after you’re done. Brush your teeth twice every day with a soft toothbrush and fluoride toothpaste, and try not to brush too hard. Rinsing daily with a fluoride mouthwash also helps protect enamel.
