it has come to my attention that there are people out here brushing their teeth right after eating

Most dentists suggest brushing either before breakfast or 30 minutes after eating. “We definitely recommend holding off on brushing after consuming anything acidic, whether it’s fruit, soda, juice, or sour candy,” says Dr. Rolle. “Acids weaken the outer layer of the tooth called the enamel.” Brushing while acids are still in the mouth can damage that layer.

After eating or drinking something acidic, instead of brushing Dr. Rolle recommends rinsing with or drinking water to help protect the enamel.
