Periodontal or gum disease is the inflammation of the gums. It is caused by plaque, a thick film of bacteria that builds up on the teeth. Symptoms include:

• Red, swollen, tender, painful or bleeding gums.
• Persistent bad breath.
• A bad taste in your mouth.
• Loose teeth, drifting apart of teeth, and gaps appearing between teeth.
• Abscesses between teeth and gums.

Treatment includes removal of buildups of plaque and calculus using dental instruments.
