Gingivitis is a form of periodontal disease. Periodontal disease is inflammation and infection that destroys the tissues that support the teeth. This can include the gums, the periodontal ligaments, and the tooth sockets (alveolar bone).
Gingivitis is due to the long-term effects of plaque deposits on your teeth. Plaque is a sticky material made of bacteria, mucus, and food debris that builds up on the exposed parts of the teeth. It is also a major cause of tooth decay.
If you do not remove plaque, it turns into a hard deposit called tartar (or calculus) that becomes trapped at the base of the tooth. Plaque and tartar irritate and inflame the gums. Bacteria and the toxins they produce cause the gums to become infected, swollen, and tender.
The following raise your risk for gingivitis:
- Certain infections and body-wide (systemic) diseases
- Poor dental hygiene
- Pregnancy (hormonal changes increase the sensitivity of the gums)
- Uncontrolled diabetes
- Misaligned teeth, rough edges of fillings, and ill-fitting or unclean mouth appliances (such as braces, dentures, bridges, and crowns)
- Use of certain medications, including phenytoin, bismuth, and some birth control pills
Many people have some amount of gingivitis. It often develops during puberty or early adulthood due to hormonal changes. It may last or come back often, depending on the health of your teeth and gums.
