What is the difference between gingivitis and periodontitis?

Gingivitis is the mildest form of gum inflammation and is usually caused by plaque. The gums become red and swollen and bleed when touched. This form of inflammation does not affect the underlying jawbone. With good oral hygiene and cleaning by a dental hygienist, gingivitis is reversible. Periodontitis, on the other hand, develops when gingivitis is left untreated. The inflammation then spreads to the jawbone that supports the teeth. This can lead to loss of supporting tissue and eventually to loose teeth. Periodontitis requires specialist treatment by a periodontist. The damage is often permanent, but it can be stabilised. Early detection is crucial to prevent serious consequences.
