Receding Gums: Causes, Stages, and Treatment Options

A little more tooth showing at the gumline each year rarely feels urgent — until a cold drink suddenly stings, or a dentist points out root surfaces that used to be covered by gum. Gum recession is common, but it doesn't reverse on its own, and catching it early changes the treatment options available.

What Gum Recession Actually Is

Recession happens when the gum tissue surrounding a tooth pulls back, exposing more of the tooth's root. Roots aren't covered by the hard enamel that protects the crown, so once exposed, they're more prone to sensitivity, decay, and further recession if the cause isn't addressed.

What Causes It

Gum disease

Periodontitis is the leading cause of recession — bacterial infection breaks down the gum and bone supporting the tooth over time.

Aggressive brushing

Brushing too hard, or using a hard-bristled brush, wears away gum tissue mechanically — a slower, more mechanical process than gum disease but just as damaging over years.

Genetics

Some people are simply born with thinner gum tissue that's more prone to recession, even with excellent oral hygiene.

Misaligned teeth or bite pressure

Teeth that sit outside the normal bone contour, or uneven bite pressure from grinding, put localized strain on the gum covering them.

Tobacco use and piercings

Both cause direct, localized gum tissue damage — piercings from the jewelry rubbing on soft tissue, tobacco from reduced blood flow to the gums.

How Dentists Stage Recession

Dentists classify recession by how much gum and bone has been lost, and — critically — whether it extends past the border between the gum and the tissue that doesn't attach to the tooth. This staging isn't just descriptive: it directly determines whether a graft can realistically cover the exposed root or only partially improve it.

Treatment by Stage

Early, mild recession

Addressing the cause — a softer brush, corrected brushing technique, treating gum disease — is often enough to stop it from progressing further, even though the tissue already lost won't grow back on its own.

Moderate recession with sensitivity

Desensitizing treatments and, in some cases, a bonded restoration over the exposed root can manage symptoms without surgery.

Significant recession

Gum grafting — using tissue from the roof of the mouth or a donor graft material — physically covers the exposed root and restores the gum's protective barrier. Success depends heavily on the stage at the time of treatment.

When to See a Dentist

See a dentist if you notice teeth appearing longer than before, new sensitivity to hot, cold, or sweet, or visible notches at the gumline. Recession caught early is far easier to stop — and far more likely to respond well to grafting if treatment is eventually needed.
