Cavity

[Jason Yan]

The one word you never want to hear in a [dentists] office. A cavity develops when a tooth decays or breaks down by bacteria. It is a hole that can grow bigger and deeper over time, even if you brush and [floss] regularly. If you have a cavity, its important to get it repaired, as brushing and [flossing] will not remove away the cavity. If left untreated, it can cause a lot of pain and discomfort. It can spread to the root area and cause an [abscess] (infection). This infection can then spread throughout the head and cause severe damage. If this goes untreated, it could even cause death.
