As you know, proper nutrition plays a key role in your overall health. It also has an obvious and direct effect on your teeth and mouth.
The fuel that allows plaque to form is sugar. Eating foods that have high concentrations of sugar may put you at a higher risk for developing tooth decay and gum disease than other types of more healthful foods.
If you limit your intake of foods like cookies, pastries, candy, soft drinks, and chewing gum and replace them with snacks like fresh fruit (which is lower in sugar), you will significantly reduce your risk of tooth decay and gum disease.
It is also very important to have your teeth professionally cleaned and examined by your dentist every six months.
