Can Receding Gums Grow Back?
No. Gum tissue does not regenerate like skin or some other tissues in your body. Once the gum has pulled away from the tooth and the root surface is exposed, that tissue will not return on its own. No toothpaste, mouthwash, or home remedy can regrow gum tissue.
This is an important distinction to understand because many products are marketed with claims about reversing gum recession. While some products can reduce gum inflammation and help keep existing gum tissue healthy, they cannot restore tissue that has already been lost. If you are seeing exposed root surfaces or your teeth look longer than they used to, the recession has already occurred.
The good news is that dental treatment can restore coverage over exposed roots, and changes to your habits can stop recession from getting worse. Understanding the cause of your recession is the first step toward the right solution.
What Causes Gum Recession?
Gum recession has multiple causes, and identifying the specific cause in your case determines the treatment approach. Some causes are preventable, while others are related to anatomy or genetics.
Preventable Causes
- Aggressive brushing: Using a hard-bristled toothbrush or brushing with too much force wears away gum tissue over time. This is one of the most common causes of recession, especially on the outer surfaces of teeth.
- Gum disease (periodontal disease): Bacterial infection destroys the gum tissue and the bone supporting your teeth. This is the most serious cause of recession because it involves ongoing tissue and bone loss.
- Tobacco use: Smoking and smokeless tobacco products damage gum tissue and reduce blood flow, accelerating gum recession.
- Teeth grinding (bruxism): Chronic grinding or clenching places excessive force on the teeth and surrounding gum tissue, which can cause the gums to recede.
Anatomical and Genetic Factors
- Thin gum tissue (thin biotype): Some people are born with thinner gum tissue that is more prone to recession. This is genetic and not caused by poor hygiene.
- Tooth position: Teeth that are positioned outside the normal arch (labially displaced) have thinner bone and gum tissue on the outer surface, making them more vulnerable to recession.
- Frenum pull: A frenum (the small fold of tissue connecting the lip or cheek to the gum) can pull on the gum margin if it attaches too close to the tooth, contributing to recession.
- Orthodontic treatment: In some cases, moving teeth through the bone during orthodontic treatment can thin the bone and gum tissue, leading to recession during or after treatment.
Treatment Options for Gum Recession
While gums cannot reverse recession naturally, several professional treatments can restore gum tissue coverage over exposed roots. The best option depends on how much recession is present, the cause, and the condition of the surrounding tissue and bone.
Gum Graft Surgery
Gum grafting is the most established treatment for gum recession. A periodontist takes a small piece of tissue, usually from the roof of your mouth (palate) or from adjacent gum tissue, and attaches it over the exposed root surface. The grafted tissue heals in place and provides new coverage.
There are three main types of gum grafts. A connective tissue graft uses tissue from under the surface of the palate and is the most common type. A free gingival graft uses tissue directly from the palate surface and is used to thicken thin gums. A pedicle graft rotates tissue from the gum adjacent to the affected tooth. Your periodontist will recommend the type best suited to your situation.
Gum graft surgery has a high success rate for root coverage. Studies report root coverage of 70% to 100% depending on the technique, the severity of recession, and the condition of the underlying bone. Recovery typically takes 1 to 2 weeks, with mild to moderate discomfort managed by over-the-counter pain relievers.
Pinhole Surgical Technique (PST)
The pinhole surgical technique is a minimally invasive alternative to traditional gum grafting. Instead of cutting and suturing donor tissue, the periodontist makes a tiny hole (the size of a pinpoint) in the gum above the receded area. Through this hole, special instruments loosen the existing gum tissue and reposition it downward over the exposed root. Collagen strips are placed through the pinhole to stabilize the tissue in its new position.
PST has the advantage of no scalpel incisions, no sutures, and no tissue harvesting from the palate. Recovery is typically faster, with less discomfort than traditional grafting. However, PST is not appropriate for every case. It works best when there is adequate existing gum tissue to reposition and when the underlying bone is intact. Your periodontist can determine whether you are a candidate.
Allografts and Collagen Matrices
For patients who prefer to avoid tissue harvesting from the palate, processed human donor tissue (allograft) or collagen-based matrices can serve as the graft material. These materials are placed over the exposed root surface and your body incorporates them as the area heals.
Allografts and collagen matrices reduce post-operative discomfort because there is no palate wound. However, some studies suggest that root coverage results may be slightly less predictable than with connective tissue grafts taken from your own mouth. Your periodontist will discuss the trade-offs with you.
How to Stop Gum Recession From Getting Worse
Even if you choose not to have gum graft surgery, or if your recession is mild and stable, there are steps you can take to prevent further tissue loss.
Steps to Prevent Further Recession
- Switch to a soft-bristled toothbrush and use gentle, circular motions rather than aggressive back-and-forth scrubbing.
- If gum disease is present, get it treated. Scaling and root planing (deep cleaning) removes the bacterial deposits that destroy gum tissue and bone.
- If you grind your teeth, ask your dentist about a custom night guard to reduce the force on your teeth and gums.
- Quit smoking or using smokeless tobacco. Tobacco use accelerates gum recession and impairs healing.
- Maintain consistent oral hygiene: brush twice daily, floss daily, and see your dentist for regular cleanings.
When Monitoring Is OK vs. When Treatment Is Needed
Not every case of gum recession requires surgery. A periodontist will evaluate your recession and recommend treatment or monitoring based on several factors.
Monitoring May Be Sufficient When
- The recession is mild (1 to 2 mm) and has been stable over time.
- There is no sensitivity, pain, or cosmetic concern.
- The underlying cause has been addressed (you have switched to a soft brush, gum disease is treated, etc.).
- The tooth has adequate remaining attached gum tissue (keratinized tissue) to protect it.
Treatment Is Typically Recommended When
- Recession is progressing despite addressing the cause.
- The exposed root is sensitive to hot, cold, or touch.
- There is less than 2 mm of attached (keratinized) gum tissue remaining, increasing the risk of further recession.
- The recession affects the appearance of your smile and concerns you.
- Root surface cavities are developing on the exposed tooth surface.
- The tooth is at risk of being lost if the recession and bone loss continue.
Gum Recession Treatment Costs
The cost of treating gum recession varies based on the type of procedure, the number of teeth involved, and your geographic location. Gum graft surgery typically ranges from $600 to $1,200 per tooth. Treating multiple adjacent teeth in a single session often costs less per tooth than treating each one individually.
The pinhole surgical technique may cost more per session because it is a newer, specialized procedure. Costs typically range from $1,000 to $3,000 depending on the number of teeth treated. Some dental insurance plans cover gum grafting when it is medically necessary (not purely cosmetic). Contact your insurance provider for specifics. Costs vary by location, provider, and case complexity.
When to See a Periodontist for Gum Recession
A periodontist is the dental specialist with advanced training in the gum tissue and bone that support your teeth. If you notice your teeth looking longer, feel sensitivity at the gumline, or see exposed root surfaces, a periodontist can evaluate the cause, measure the severity, and recommend whether treatment or monitoring is the right approach.
You should see a periodontist if your general dentist has noted recession at your check-ups, if you have a history of gum disease, if you are experiencing root sensitivity, or if you are concerned about the appearance of receding gums. Early evaluation gives you more treatment options and better outcomes.
