What is gingivitis?
Gingivitis is an inflammation of the gums. This inflammation is usually caused by plaque buildup along the gum line. Plaque contains bacteria that irritate the gums and can trigger inflammatory reactions.
Gingivitis is initially limited to the gums. This is important because, at this stage, the damage is usually still reversible. If gingivitis is left untreated, it can progress to periodontitis, which can also affect the supporting tissues and jawbone.
