Is there ever a bad time to brush your teeth?
Most of us believe that proper dental caremeans flossing and brushing often — at a minimum, twice daily, as the American Dental Association recommends. Those who are particularly diligent may brush more often, after meals, snacks or sugary drinks.
But research shows that brushing too soon after meals and drinks, especially those that are acidic, can do more harm than good. Acid reflux poses a similar problem: While it might seem like a good idea to brush after a reflux episode, doing so can damage your teeth.
Acid attacks the teeth, eroding enamel and the layer below it, called dentin. Brushing can accelerate this process, said Dr. Howard R. Gamble, president of the Academy of General Dentistry. “With brushing, you could actually push the acid deeper into the enamel and the dentin,” he said.
