It all starts with what you put into your body. The food you eat contains sugars and carbohydrates that bacteria convert to acid in your mouth.
This acid then wears away your tooth enamel, which is what protects your teeth against the onslaught of tooth decay. The best foods for your teeth, according to WebMD, are firm and crunchy fruits and vegetables. These can include apples, pears, carrots, celery, and others. Foods like apples also act as natural ‚Toothpastes’, as the texture and crunch help clean teeth while protecting enamel.
The article also recommends cheeses, chicken and other meats, and nuts as part of the‚ tooth-friendly diet. These foods are rich in calcium and phosphorus, which helps re-mineralize your tooth enamel after it has been eroded by acids.
