The pulp provides nourishment for the tooth during growth and development. Once the tooth is mature, the pulp's only function is sensory. A fully developed tooth can survive without the pulp. If this tissue is damaged, your tooth can be saved with root canal therapy. The roots of your teeth are anchored by bone.
Healthy teeth stimulate and keep bone tissue healthy and vice versa.
This part of the tooth sits in the bone below the gum. Believe it or not, the root of your tooth is usually twice as long as the crown, the part you see above the gumline. It covers the bone surrounding your teeth. When you brush your teeth after meals and floss daily, you keep this tissue healthy. That's important, because gum disease can cause bone lose.
