what causes receding gums

Receding gums happen when the gum tissue pulls away from the teeth and exposes the roots, and they usually develop slowly over time rather than all at once. They are often linked to gum disease and mechanical wear, but several different factors can combine in the same mouth.

Main medical causes

• Gum disease (gingivitis and periodontitis) : Long‑term plaque and tartar buildup lead to inflammation, infection, and destruction of the tissues and bone that support the teeth, making the gums detach and recede. This is considered the leading medical cause of gum recession.

• Systemic conditions: Diabetes, HIV, and other health problems that weaken immunity or healing can make gum disease more likely and more severe, increasing the risk of recession. Some people also have a genetic tendency to develop gum disease even with good daily care.

Everyday habits that cause wear

• Aggressive toothbrushing: Brushing too hard, using a hard‑bristled brush, or scrubbing with a sawing motion can physically wear away gum tissue over years, even in people who otherwise clean well. This often shows up as notches near the gumline and “longer” looking teeth.

• Poor oral hygiene: Infrequent brushing and flossing lets sticky plaque harden into tartar, which the toothbrush can’t remove and which irritates the gums, leading to inflammation and eventual recession.

Lifestyle and risk factors

• Tobacco use: Smoking and other tobacco products promote sticky plaque and reduce blood flow in the gums, making infection and recession more likely.

• Hormonal changes in women: Puberty, pregnancy, and menopause can make gums more reactive and vulnerable to inflammation, which can accelerate recession if plaque is present.

• Dry mouth and medications: Drugs that reduce saliva flow leave tissues less protected, so they are more easily irritated or infected and may recede over time.

Bite, grinding, and physical trauma

• Teeth grinding (bruxism) and clenching: Excessive forces on teeth can damage the supporting bone and cause gums around overloaded teeth to recede.

• Misaligned bite or crooked teeth: When certain teeth take too much force, the bone and gum around them can thin out and recede.

• Local trauma and friction: Lip, cheek, or tongue piercings, ill‑fitting dental appliances, and repeated small injuries to the gum can physically break down the attachment and cause localized recession.

Age and “can they grow back?”

• Ageing: Mild gum recession is common with age, partly from years of mechanical wear and low‑grade inflammation.

• Regrowth: Once significant gum tissue is lost, it generally does not grow back on its own, so treatment focuses on stopping progression and, when needed, procedures like gum grafts to cover exposed roots.
