Dentists at Columbia University Irving Medical Center and Mayo Clinic says that people should wait about 30 minutes to brush their teeth after eating acidic food or drink. weak acid enamel — the outer protective layer of the teeth — and brushing too soon can remove this layer, which can increase the risk of tooth decay.

“Foods and drinks that are high in acid will wear away the enamel that protects your teeth,” reports According to the American Dental Association on its website. “This changes the appearance of your teeth and creates an opportunity for bacteria that can cause tooth decay or infection.”

North Boulder Dental Corporation explained that human teeth undergo two processes known as demineralization and remineralization every day. Demineralization occurs when bacteria from the foods and drinks we consume during the day produce acids that attack tooth enamel.

Dentists say waiting about 30 minutes to brush your teeth after eating acidic foods or drinks helps enamel remineralize and rebuild itself.
