Be Careful Brushing Your Teeth After Eating These 3 Things
Conventional wisdom tells us that if you eat something that’s harsh on your teeth, you should brush them immediately to avoid further damage. Yet experts say that in some cases the opposite is true: When you eat foods that compromise your tooth enamel, you should hold off on brushing. Derek Chung, DMD, a Toronto-based dentist and the founder of Paste Dental, shared in a recent TikTok video that three foods and drinks in particular require a 15- to 20-minute wait period before you brush. Read on to learn when you shouldn’t immediately brush your teeth, according to the dental expert.
Brushing After Breakfast
In his recent TikTok post, Chung says there’s one question he gets asked every day as a dentist. Patients regularly want to know whether they should brush their teeth before or after having breakfast. “It’s the age-old debate,” he says—and his answer may surprise you. “To be honest, it’s OK to brush your teeth before, but do not brush your teeth directly after having breakfast. The enamel is more thin, your mouth is more acidic, and you will literally brush away the enamel,” he warns. Instead, Chung says you should hold off for 15 to 20 minutes after eating, and then brush. While you wait, you can drink some water or rinse with mouthwash.
Brushing After White Wine
Another time that you shouldn’t brush your teeth immediately is after having a glass of white wine, Chung says. Besides the sour taste it would leave in your mouth, the dentist warns that the acidity of the beverage can damage your enamel under the harsh scrub of a toothbrush. “People don’t believe this but white wine can be just as bad for your teeth as red wine,” he notes in the video. “So if you have a glass of white wine, do not brush your teeth right after because of the acidity. Again, your enamel is softer, so you’re going to brush away your enamel.”
Brushing After Kimchi
Fermented foods can also leave your teeth vulnerable to damage, Chung says. In particular, he advises against brushing immediately after eating kimchi—one of his own favorite foods. “Kimchi is very acidic—it’s basically like an Asian pickle,” he explains. “If you’ve had a lot of kimchi… the enamel is softer. Do not brush your teeth right after or you’re going to brush away your enamel.”
