Dentists Warn Against Brushing Straight After Eating
Dentists are constantly urging people to clean their teeth to prevent oral diseases, such as tooth decay and gum disease, however, brushing too soon after eating could actually do more harm than good and dentists advise waiting at least an hour to brush.
Brushing within 20 minutes of eating foods, especially those that are sugary or acidic, actually damages the teeth, as sugary and acidic foods weaken the enamel temporarily. Brushing during this danger period can cause wear and damage to the enamel, causing the dentin to become exposed and increasing the risk of sensitivity and decay.
Dr Howard Gamble, from the Academy of General Dentistry, said that brushing shortly after eating can cause the acid to be pushed deeper inside the teeth, into the enamel and dentin.
A research study found that the teeth were corroded faster if brushed within 30 minutes of drinking an acidic drink. Trials showed that brushing between 30 and 60 minutes after eating or drinking did not cause any more wear than general brushing.
