Highlights & Basics
- Gingivitis is caused by bacterial plaque (dental biofilm) that accumulates daily on the teeth.
- Results in redness, slight swelling, or "puffiness" of the gums and bleeding on tooth brushing.
- Treatment involves thorough professional tooth cleaning and effective daily removal of dental plaque by tooth brushing and cleaning between the teeth.
- Necrotizing gingivitis is a more serious condition that is mainly found in developing countries and is associated with people with severe malnutrition or people living with HIV with low CD4 counts.
