Periodontal Disease

What is periodontal disease?
Periodontal disease is a severe gum infection that harms the bone and soft tissue which support the teeth.  The alveolar bone around the teeth gradually loses and make patients feel uncomfortable.

Bleeding, pain, redness and swelling for serious cases. If it is not handled on time, gums will shrink and results in exposing tooth roots and displacement of teeth. Late stage of periodontal disease even causes teeth loss.
