Receding Gums: Causes, Treatment, and Whether They Grow Back

Gum recession is the condition that occurs when the gum line around a tooth recedes, revealing the roots of the teeth. Approximately one in every four adults in the United States has measurable gums that have receded by 3 mm or more. These are the primary causes: gum disease, excessive brushing, genetics, smoking, and teeth grinding. Gingivitis cannot be cured by itself. They can be treated with better oral hygiene, deep cleans, or surgical measures such as gum grafts and pinhole surgical technique. It is important to treat the disease at an early stage so that the loss of teeth can be avoided.

What Are Receding Gums?

Gingival recession (also known as receding gums) occurs when the pink gum tissue that surrounds the teeth moves back or wears away. As the gums recede more of the tooth and the tooth root is exposed. A healthy gum snugly surrounds the teeth and protects the sensitive surfaces of the roots below. Without that protection, teeth can be more susceptible to tooth sensitivity, tooth decay and eventual tooth loss.

Knowing what to know about receding gums. Chan and his team's research, published in the Journal of the American Dental Association, found that 23% of U.S. adults over age 30 have at least one tooth surface with 3 mm or more of gum recession. More than half of all American adults have some degree of gum recession. Gums will not regenerate back into place. Gum disease, teeth grinding, genetics, smoking and aggressive brushing are common causes. The progress can be halted with treatment and lost tissue coverage can be regained with surgery such as a gum graft or pinhole surgical technique.

Gum recession typically starts to occur in adults after age 30, but may also happen in younger persons. According to the American Dental Association (ADA), gum disease is among the top causes of adult tooth loss. Try August AI for oral health monitoring and reminders.

Causes of Receding Gums

The causes of receding gums are many, and most people develop the condition from a combination of factors rather than just one.

Gum disease. This is the top cause. Plaque buildup along the gumline triggers inflammation (gingivitis), which can progress to periodontitis. Periodontitis damages the soft tissue and the bone that supports your teeth. The American Dental Association notes that gingivitis is reversible with professional cleaning, but periodontitis causes permanent tissue and bone loss.

Aggressive brushing. Brushing too hard or using a hard-bristled toothbrush wears away the delicate gum tissue. The ADA recommends a soft-bristled brush with gentle, circular motions rather than scrubbing.

Genetics. Up to 30% of people are genetically predisposed to gum disease, even with good oral care. Family history matters.

Smoking and tobacco use. Tobacco reduces blood flow to the gums and impairs healing, accelerating gum recession.

Teeth grinding (bruxism) and clenching. The pressure from grinding stresses gum tissue and supporting bone.

Hormonal changes. Pregnancy, menstruation, and menopause can make gums more sensitive and prone to recession.

Misaligned teeth or bite. Uneven pressure from a misaligned bite stresses the gum tissue around certain teeth.

Oral piercings. Tongue and lip piercings can rub against the gums and cause localized recession.

Poor oral hygiene. Inadequate brushing and flossing allows plaque to harden into tartar, which can only be removed by professional cleaning. Receding gums are also linked to cardiovascular disease and diabetes, per Cleveland Clinic overviews.

Symptoms and Warning Signs

Gum recession often progresses slowly, which is why many people miss the early signs. Watch for:

• Teeth that look longer than they used to

• A notch or step you can feel at the gumline

• Increased tooth sensitivity to hot, cold, or sweet

• Visible tooth roots

• Red, swollen, or bleeding gums

• Bad breath that does not improve with oral care

• Loose teeth in advanced cases

• A change in how your teeth fit together when biting

The National Institute of Dental and Craniofacial Research defines a normal gum pocket as 1 to 3 mm deep. Pockets deeper than 3 mm signal gum disease and possible recession. Your dentist measures pocket depth at each cleaning using a small probe.

Can Receding Gums Grow Back?

The honest answer to can receding gums grow back is no, not on their own. Once gum tissue has been lost, the body does not regenerate it the way it heals skin cuts. This is one of the most common misconceptions about gum health.

What you can do is stop the recession from getting worse and, in some cases, restore lost coverage through surgery. A dentist or periodontist can:

• Halt progression with improved oral hygiene and professional cleaning

• Cover exposed roots through gum graft surgery

• Reposition existing tissue using the pinhole surgical technique

• Rebuild bone and tissue through guided tissue regeneration

So while you cannot regrow your own gums, the right treatment can effectively restore the protective coverage around your teeth.

Receding Gums Treatment Options

The right receding gums treatment depends on the severity of recession, the underlying cause, and your overall dental health. A periodontist (gum specialist) typically evaluates the options.

Scaling and root planing. This is a deep cleaning that removes plaque and tartar from below the gumline and smooths the root surfaces. It is the first-line treatment for mild to moderate recession from gum disease. Antibiotics may be added for advanced cases.

Gum graft surgery. A periodontist takes tissue from another area of your mouth (often the roof of your mouth) or from a donor source and grafts it onto the receding area. This restores coverage over exposed roots, reduces sensitivity, and improves appearance. Recovery typically takes 2 to 3 weeks.

Chao Pinhole Surgical Technique (PST). This minimally invasive option, developed by Dr. John Chao, uses a small needle to create a tiny opening in the gum, then specialized instruments to gently glide existing tissue down over the exposed root. No incisions, no stitches, no donor tissue needed. A 2017 study in the International Journal of Periodontics and Restorative Dentistry by Reddy and colleagues reported 96.7% root coverage at 6 months with minimal complications. Recovery is dramatically faster than traditional grafts.

Guided tissue regeneration (GTR). When recession includes bone loss, a periodontist places a special membrane and regenerative material to help your body rebuild lost bone and tissue. This is used for severe cases.

Composite restoration. A tooth-colored resin can be placed over the exposed root to reduce sensitivity and improve appearance, though it does not restore gum tissue.

For people wondering how to fix receding gums, the choice of treatment depends on cause and severity. Speak with a periodontist for an evaluation.

How to Stop Receding Gums from Getting Worse

How to stop receding gums from progressing comes down to consistent daily habits and professional care.

Use a soft bristle toothbrush with fluoride toothpaste, twice a day, to brush gently. The ADA says to gently, but circularly, rub rather than scrub. Many dentists will choose an electric toothbrush that has pressure sensors to ward off over brushing.

Floss once a day to get rid of plaque between teeth and from the gum line. Consider using a water flosser or interdental brushes if flossing is difficult.

Visit your dentist for professional cleanings twice a year or more if you suffer from gum disease. Early treatment can make a big difference.

Ask your dentist if you have to grind your teeth during sleep and if they can make you a personal night guard. Smoking or tobacco use slows down the healing process and can promote inflammation that lasts.Giving up cigarettes and tobacco helps gums heal and stops continued inflammation. Carefully control diabetes and other conditions which impact gums.

Orthodontic treatment can help to decrease the pressure on some teeth and help to slow down recession in cases of misaligned bites.

Receding Gums Home Remedies

Receding gums home remedies can help support oral hygiene and reduce inflammation, but they cannot reverse existing recession. Be cautious of claims that natural products can regrow gum tissue.

Helpful supportive practices include:

• Oil pulling with coconut or sesame oil for 10 to 20 minutes daily, which some studies suggest may reduce plaque and gingivitis

• Saltwater rinses to reduce inflammation and bacteria

• Green tea, which contains antioxidants that may support gum health

• Aloe vera gel applied topically to soothe inflamed gums

• Hydrogen peroxide rinse (diluted 1:1 with water) used occasionally for antibacterial effect

The American Dental Association cautions that home remedies are supportive measures, not replacements for professional care. Receding gums home remedies cannot regenerate lost tissue. If you have noticeable recession, see a dentist.

When to See a Dentist

Schedule a dental visit if you notice any of the warning signs of gum recession. Your dentist can:

• Measure your gum pocket depths

• Take X-rays to check for bone loss

• Refer you to a periodontist if specialized care is needed

• Create a personalized treatment plan

Do not wait for pain. Most gum disease is painless until it reaches advanced stages. For ongoing oral wellness tracking, see August AI.
