The gums are firm and pink. The bone is healthy and supports the teeth.
Bacterial Plaque collects on the teeth at the gum line. Eventually the gums become red and inflamed. As the inflammation progress, the gums become red, puffy and bleed easily.
If the Inflammation continues for a long period of time. the gums will eventually pull away from the teeth forming a deep pocket or gum crevice. These pockets become filled with bacterial plaque and hard deposits, and bone is lost. The infection at this stage, is usually painless although puss may be present.
The infection over time spreads and becomes more severe. This process results in bone loss, the teeth shift and start to become loose. Advanced gum disease is one of the leading causes of tooth loss in adults. Bone loss is severe and there are gum abscesses. The infection is severe and painful.
