Gingivitis is the mildest form of periodontal disease. It causes the gums to become red, swollen and bleed easily. There is usually little or no discomfort at this stage. Gingivitis is often caused by inadequate oral hygiene. Gingivitis is reversible with professional treatment and good oral home care. If gingivitis left untreated it can lead into a more aggressive gum disease called periodontitis which involves the bone and the separation of the gum from around the teeth.
Therefore it is highly recommended that routine scaling and polishing is done every 6 months, if pocketing has formed then root planning will be needed as well.
