Recession (Gum)

Recession (Gum) occurs when the gum margin moves away from the tooth, exposing more of the crown or the root surface. This can make teeth look longer, cause sensitivity to temperature or touch, and increase the risk of root decay and further periodontal problems; common contributing factors include aggressive tooth brushing, gum disease, tobacco use, orthodontic movements, trauma and a naturally thin gum biotype.

Diagnosis is made through clinical examination, periodontal probing and sometimes dental X-rays to assess supporting bone. Treatment depends on the cause and extent of recession and ranges from improving oral hygiene and using desensitising products to periodontal therapy and surgical options such as connective tissue grafts to restore gum coverage, while restorative approaches like composite bonding or veneers may be used to protect exposed root surfaces.
