According to dentist Alex Foo, to prevent tooth damage, it is necessary to give your teeth a rest after lunch. He recommends that people do not eat or drink for two hours after lunch to help strengthen teeth and prevent tooth decay.

"Letting saliva naturally clean and remineralize teeth for at least two hours after a meal can significantly reduce the risk of tooth decay and enamel erosion," said Dr. Foo.

He explained that after lunch, the pH of saliva increases dramatically, promoting the remineralization of tooth enamel, thereby effectively protecting teeth. Tooth remineralization is the body's natural mechanism to restore tooth enamel after performing the function of chewing every day. Because the mineral layer is constantly worn away by harmful bacteria, sugar and acids in food. This is also known as demineralization, which gradually erodes the enamel, leading to tooth sensitivity.

Dr. Foo said that the food consumed at lunch also affects the quality of saliva throughout the day. Healthy eating choices will lead to a healthy mouth.

"A salad or other healthy options can promote good oral health," he says.

Whitney DiFoggio, a dentist in New York, agrees. To keep teeth bright, Dr. DiFoggio previously said that to keep teeth bright, people should avoid fermentable carbohydrates in their diet - such as white bread, pasta, chips, cereals and cookies.

"Fermentable carbohydrates are bad for teeth because they break down into sugar while in the mouth. This is the hidden sugar that can erode teeth," she explains.
