The tissue in the pulp is kept alive by the blood vessels that come from the tip of the root and travel along the root canal into the tooth. Decay is the main reason for pulp in the tooth dying. Once the decay has reached the pulp, it will keep eating away until the pulp has died. Once it dies, the toxins from the decay will be released into the root tip and make it s way into the jawbone.

If you ve had a cold you should replace your toothbrush, simply because the bristles can contain germs that could get you sick all over again.

The main problem many people have against flossing is the fact that it can result in bleeding of the gums. Anytime you floss and get between your teeth and around your gums, the floss will rub against your gums, resulting in bleeding. Many people take this the wrong way, and immediately stop flossing, usually for good.
