In addition to practicing good oral hygiene and visiting your dentist for periodontal cleaning at least once annually, there are several supplements that you can take to help keep your teeth healthy and heal irritated and bleeding gums. There are many natural choices for healthy teeth and gums. Calcium supplements can strengthen the bone in which the teeth are anchored, helping prevent tooth loss, while Vitamin A also helps promote healing of inflamed gums. Natural therapies should be included in your daily routine along with brushing your teeth.
