What Is Gum Recession and Why Does It Matter?
Gum recession is the gradual loss of gum tissue along the edge of your teeth. As the gums pull back, more of the tooth root becomes exposed. This is a problem because tooth roots are not covered by hard enamel like the crown of the tooth. Exposed roots are vulnerable to decay, sensitivity, and further tissue loss.
Many people do not realize their gums are receding until the problem is well advanced. The process is slow, and early recession does not cause pain. You may first notice that a tooth looks longer than it used to, or you may feel a notch near the gum line with your fingernail. Sensitivity to hot or cold drinks is another common early sign.
Gum recession does not reverse on its own. Once the tissue is gone, it will not grow back without treatment. However, the good news is that treatments exist for every stage of recession, from minor adjustments in your daily routine to surgical procedures that can restore lost tissue.
What Causes Gum Recession?
Understanding what caused your recession is the first step in fixing it. If you treat the recession but not the cause, the problem will return.
Aggressive Brushing
Brushing too hard or using a medium- or hard-bristle toothbrush is one of the most common causes of gum recession. Over time, forceful brushing wears away gum tissue, especially on the side of the mouth opposite your dominant hand. Switching to a soft-bristle brush and using gentle, circular strokes can stop further damage.
Periodontal Disease
Gum disease (periodontal disease) is the other leading cause. Bacterial infection destroys the gum tissue and the bone that supports your teeth. When bone is lost, the gums recede along with it. Treating gum recession caused by periodontal disease requires addressing the infection first, usually through scaling and root planing (deep cleaning) before any grafting procedure.
Other Contributing Factors
- Genetics: Some people are born with thinner gum tissue that is more prone to recession, regardless of their brushing habits.
- Teeth grinding (bruxism): Clenching or grinding places excessive force on the teeth and gums, which can accelerate tissue loss.
- Misaligned teeth or bite problems: Teeth that are crowded or positioned outside the natural arch put uneven pressure on the gum tissue.
- Tobacco use: Smoking or chewing tobacco reduces blood flow to the gums and promotes plaque buildup, both of which increase recession risk.
- Lip or tongue piercings: Jewelry that rubs against the gum tissue can wear it away over time.
Treatment Options by Severity
Your periodontist will measure the amount of recession in millimeters and assess whether the underlying bone is also affected. Treatment recommendations depend on the severity of tissue loss and the cause.
Mild Recession (1-2mm)
Mild recession does not always require surgery. If the recession is stable, the root is not sensitive, and there is no active gum disease, your periodontist may recommend monitoring the area while you make changes to protect the tissue you still have.
For mild cases, treatment focuses on prevention. Switch to a soft-bristle toothbrush and use gentle pressure. Your dentist or periodontist may apply a fluoride varnish or desensitizing agent to the exposed root to reduce sensitivity. If grinding is a factor, a night guard can help. Regular cleanings every 3 to 6 months keep plaque and tartar under control.
Moderate Recession (3-4mm)
When recession reaches 3 to 4 millimeters, the exposed root surface is at higher risk for decay and sensitivity. At this stage, most periodontists recommend a gum graft to cover the exposed root and rebuild the gum line.
There are several types of gum graft procedures. A connective tissue graft takes tissue from the roof of your mouth and places it over the receded area. A free gingival graft uses a small piece of tissue directly from the palate. An allograft uses donor tissue instead of your own, which avoids the second surgical site. Your periodontist will recommend the approach that fits your specific situation.
Severe Recession (5mm or More)
Severe recession often involves bone loss beneath the gum tissue. When both the gum and the supporting bone have deteriorated, a gum graft alone may not be enough. In these cases, the periodontist may perform a bone graft first to rebuild the foundation, followed by a gum graft to cover and protect the area.
Guided tissue regeneration (GTR) is another option for severe cases. The periodontist places a biocompatible membrane between the bone and gum tissue to encourage your body to regenerate bone and tissue in the damaged area. The specific combination of procedures depends on the location, the amount of bone loss, and the overall health of the surrounding teeth.
Non-Surgical Treatments for Gum Recession
Not every case of gum recession requires surgery. Several non-surgical approaches can slow or stop recession and protect exposed roots.
Scaling and Root Planing
If gum disease is present, scaling and root planing (deep cleaning) is typically the first step. The hygienist or periodontist removes plaque and tartar from below the gum line and smooths the root surfaces so the gums can reattach more tightly to the tooth. This procedure does not reverse recession, but it stops the infection that causes further tissue loss.
Desensitizing Agents and Bonding
For patients who have mild recession with root sensitivity but are not yet candidates for surgery, your dentist can apply desensitizing agents or bond a tooth-colored resin over the exposed root. Bonding covers the root surface, reduces sensitivity, and improves appearance. This is not a permanent fix for the underlying recession, but it can provide relief while you and your periodontist monitor the area.
Orthodontic Tooth Movement
In some cases, moving a misaligned tooth back into its proper position within the bone can reduce recession. This is most effective when the recession was caused by the tooth sitting outside the arch of bone. An orthodontist and periodontist may coordinate care to first move the tooth and then graft the tissue if needed.
Surgical Treatments for Gum Recession
When recession is moderate to severe, surgery is the most reliable way to restore lost gum tissue and protect the tooth long-term.
Connective Tissue Graft
This is the most commonly performed gum graft procedure. The periodontist creates a small flap in the roof of your mouth and removes a piece of connective tissue from underneath. That tissue is then stitched over the exposed root. Over several weeks, the graft integrates with your existing gum tissue and blood supply, creating a thicker, more durable gum line.
Pinhole Surgical Technique
The pinhole technique is a minimally invasive alternative to traditional grafting. The periodontist makes a small hole in the gum tissue above the receded area and uses instruments to gently loosen and reposition the tissue down over the exposed root. Collagen strips are then placed to hold the tissue in its new position. This technique avoids the need for a tissue donor site and typically involves less post-operative discomfort.
Guided Tissue Regeneration
When bone loss accompanies gum recession, guided tissue regeneration helps the body rebuild both bone and tissue. The periodontist places a biocompatible membrane, sometimes combined with bone graft material and growth factors, at the site of the defect. The membrane acts as a barrier, preventing fast-growing gum tissue from filling the space before slower-growing bone has a chance to regenerate.
How to Prevent Gum Recession
Prevention is the most effective treatment for gum recession. Once tissue is lost, only surgery can restore it. These habits protect the gum tissue you have.
- Use a soft-bristle toothbrush and brush with gentle, circular motions rather than a back-and-forth scrubbing motion.
- Floss daily to remove plaque from between teeth where your toothbrush cannot reach.
- See your dentist or periodontist for regular cleanings every 6 months, or more often if you have a history of gum disease.
- If you grind your teeth at night, ask your dentist about a custom night guard to reduce the pressure on your gums and teeth.
- Quit smoking or using tobacco products. Tobacco use significantly increases the risk of gum disease and recession.
- Address misaligned teeth. Orthodontic treatment can reposition teeth within the bone and reduce stress on the gum tissue.
Cost of Gum Recession Treatment
The cost of treating receding gums varies based on the type of treatment, the number of teeth involved, and your geographic location.
Non-surgical treatments like scaling and root planing typically cost $200 to $400 per quadrant of the mouth. A gum graft procedure generally costs $600 to $1,200 per tooth. If a bone graft is also needed, that adds $300 to $800 per site. The pinhole surgical technique may cost $1,000 to $3,000 depending on how many teeth are treated in one session. Costs vary by location, provider, and case complexity.
Many dental insurance plans cover a portion of gum recession treatment when it is deemed medically necessary. Scaling and root planing is typically covered under periodontal benefits. Gum grafts may be partially covered if the procedure is necessary to save the tooth rather than purely cosmetic. Check with your insurance provider for your specific coverage details. Many periodontist offices also offer payment plans or financing options.
When to See a Periodontist for Receding Gums
A periodontist is a dental specialist with 3 additional years of training beyond dental school, focused on the gums, bone, and supporting structures of the teeth. While your general dentist can monitor mild recession, a periodontist should evaluate your gums if any of the following apply.
- You can see exposed root surfaces on one or more teeth.
- Your teeth are increasingly sensitive to hot, cold, or sweet foods and drinks.
- Your gums bleed when you brush or floss, which may indicate underlying gum disease causing the recession.
- You have been told by your dentist that you have moderate to severe recession.
- You have a family history of gum disease or early tooth loss.
- Previous treatment for recession has not stopped the progression.
