Gum Recession: Causes, Consequences, and Treatment

Gum recession — when gum tissue pulls away from the tooth, exposing the root — affects a significant portion of adults and is one of those conditions where early attention matters enormously. Exposed roots are not just a cosmetic concern; root surfaces are less protected than enamel, more sensitive, and more susceptible to decay and damage.

Common Causes

• Periodontal disease: The most common cause. Bacterial infection destroys the gum tissue and bone.
• Aggressive brushing: Scrubbing teeth with a hard-bristled brush or using too much force wears away gum tissue over time. This is especially common in patients who associate "clean" with scrubbing hard.
• Thin gum tissue: Some people are genetically predisposed to thin, fragile gum tissue that recedes more easily.
• Teeth grinding (bruxism): Excessive force on teeth can contribute to recession.
• Tongue or lip piercings: Metal jewelry rubbing against the gums causes localized recession over time.
• Poor tooth position: Teeth outside the normal arch are more prone to recession.

Symptoms

Teeth look longer than they used to. Sensitivity to cold, hot, or sweet foods and drinks at the gumline. Notch-like indentations at the gumline. Roots visible as a yellowish area where the tooth meets the gum.

Treatment

Mild recession: Address the cause (switch to a soft-bristled brush, treat gum disease, wear a night guard). Monitor with regular exams. Desensitizing toothpaste or in-office fluoride treatments for sensitivity.

Moderate to severe recession: Gum grafting surgery. The most common type is a connective tissue graft — a small amount of tissue is harvested from the palate (or donor tissue is used) and sutured at the recession site. This covers exposed roots and creates thicker, more resilient gum tissue. Most patients experience significant reduction in sensitivity and improved appearance. Recovery is 1–2 weeks.

Can Receded Gums Grow Back on Their Own?

No. Unlike some other tissues, gum tissue does not regenerate on its own once it has receded. Early treatment stops further recession; surgery reverses existing recession. This is why monitoring by your dentist is important — catching it early preserves your options.
