Always Brush Your Teeth After Getting Sick

If you’re having trouble with extreme nausea or vomiting, be sure to brush your teeth frequently or immediately after being ill. Stomach acid erodes the enamel on your teeth, and once that enamel is gone it can’t be replaced; this puts you at risk for tooth sensitivity, cavities, and decay. If you can’t brush your teeth for some reason, rinse with an enamel-strengthening mouthwash.
