What This Guide Covers
This guide explains why gum recession becomes more common with age and what you can do about it. It covers the main causes, practical prevention steps, treatment options, and when to see a specialist.
Gum recession means that the gum tissue around your teeth pulls back or wears away. This exposes more of the tooth or even the tooth root. Recession can lead to sensitivity, root decay, and changes in how your teeth look. [2]
If you are over 40 and have noticed your teeth looking longer, sensitivity near the gumline, or a notch you can feel with your fingernail, this guide is for you. It is also useful for younger adults who want to protect their gums for the long term.
Why Gums Recede as You Get Older
Gum recession results from accumulated damage to gum tissue, not from aging itself. Several factors build up over years and decades to thin and pull back the gums.
How Common Is Gum Recession in Older Adults
Gum recession is widespread among adults, and its prevalence increases with age. An analysis of data from the National Health and Nutrition Examination Survey (NHANES), which included over 10,000 U.S. adults aged 30 and older, found that periodontitis affects nearly half of adults in that age group, with rates rising significantly in those over 65. [8] Because periodontitis is a leading cause of recession, these numbers help explain why so many older adults experience gum tissue loss.
However, prevalence alone does not mean recession is unavoidable. Most of the damage comes from specific, manageable risk factors rather than from the passage of time itself.
Decades of Brushing Habits Add Up
Aggressive tooth brushing is one of the most common causes of recession in people who have never had gum disease. Using a hard-bristled toothbrush or pressing too firmly wears away both enamel and the thin gum tissue at the base of each tooth. [5]
This damage is slow. You might not notice any change for years. But after 20 or 30 years of the same forceful technique, the gum tissue can recede several millimeters. The outer tooth surface near the gumline can also develop abfraction lesions, which are small notch-shaped defects where enamel meets the root surface. [5]
Switching to a soft-bristled brush and using gentle, short strokes can stop this type of recession from getting worse. Electric toothbrushes with pressure sensors can also help by alerting you when you press too hard. [7]
Past Gum Disease Leaves Lasting Vulnerability
Periodontal disease, an infection of the gums and bone that support your teeth, is the other major driver of recession. Even after successful treatment, the bone and tissue lost during active infection typically do not grow back on their own. [6]
According to the American Academy of Periodontology, gum disease ranges from gingivitis (early inflammation limited to the gums) to periodontitis (deeper infection that damages bone). [6] Once periodontitis has occurred, the gums may sit lower on the teeth permanently. This makes those areas more prone to further recession if plaque control slips.
Adults who were treated for gum disease in their 30s or 40s may notice recession accelerating in their 50s and 60s. The original damage left thinner tissue that is less resilient to everyday stress.
Medications and Dry Mouth
Many medications prescribed to older adults cause xerostomia (dry mouth) as a side effect. Common examples include drugs for high blood pressure, depression, allergies, and urinary incontinence. Dry mouth reduces saliva flow, and saliva plays a critical role in protecting both teeth and gums.
A 2021 review in Gerodontology noted that reduced saliva leaves tooth roots more vulnerable to decay and makes the oral environment more favorable for harmful bacteria. [2] When bacteria thrive unchecked, gum inflammation increases, and recession can follow.
If you take medications that cause dry mouth, tell your dentist. Simple steps like sipping water throughout the day, using sugar-free lozenges, or using a saliva substitute can reduce the impact on your gums.
Practical Steps to Slow or Prevent Recession
Prevention works at any age, and small habit changes can meaningfully protect your gum tissue over time.
Fix Your Brushing Technique First
Use a soft-bristled toothbrush. Hold it at a 45-degree angle to the gumline. Use gentle, circular or short back-and-forth strokes rather than long, sweeping motions. Replace your toothbrush every three to four months, or sooner if the bristles splay outward. [7]
If you have been brushing aggressively for years, switching technique can feel like you are not cleaning well enough. You are. Plaque is soft and comes off easily with gentle pressure. Hard scrubbing removes gum tissue, not additional plaque.
Manage Clenching, Grinding, and Dry Mouth
Bruxism (teeth clenching or grinding) places heavy lateral forces on teeth and the surrounding bone and gums. Over time, this can contribute to both recession and abfraction lesions near the gumline. [5] If you clench at night, a custom night guard from your dentist can reduce the force transmitted to your gums.
For dry mouth, stay hydrated and consider products designed to boost saliva production. Your dentist or physician may also be able to adjust medications to reduce this side effect. Maintaining adequate saliva flow helps control the bacteria that lead to gum inflammation and root decay. [2]
Professional Cleanings and Plaque Control
Regular professional cleanings remove hardened plaque (calculus) that you cannot remove at home. Calculus buildup along and below the gumline fuels inflammation and accelerates tissue breakdown. [6]
For most adults, cleanings every six months are standard. If you have a history of periodontal disease, your periodontist may recommend cleanings every three to four months. A 2023 randomized controlled trial in the American Journal of Dentistry found that multi-channeled oral irrigation devices also helped reduce plaque and gingivitis when used alongside regular brushing. [1]
Good home care between visits matters just as much. Floss or use an interdental brush daily to clean the areas your toothbrush cannot reach.
When to Start Paying Closer Attention
Most adults should begin monitoring their gums more carefully around age 40. This is when cumulative brushing damage and past periodontal issues often become visible. Your dentist measures recession during routine exams by checking the distance from the gumline to a fixed reference point on each tooth.
If you have risk factors like a history of gum disease, heavy clenching, thin gum tissue (biotype), or take medications that cause dry mouth, earlier and more frequent monitoring is reasonable. Ask your dentist for a periodontal screening if you have not had one recently.
What Happens During a Recession Evaluation and Treatment
A periodontal evaluation for recession is straightforward, typically completed in a single appointment with no discomfort.
The Evaluation Visit
The periodontist will visually examine your gums and use a small probe to measure the depth of gum pockets and the amount of recession at each tooth. Measurements are recorded in millimeters. X-rays may be taken to assess bone levels around affected teeth.
The periodontist will also evaluate your gum tissue thickness, called biotype. Thin biotype tissue is more susceptible to recession. Based on these findings, you will receive a classification of your recession severity and a recommendation for monitoring or treatment.
Treatment Options When Recession Progresses
For mild recession with no sensitivity or root exposure, monitoring with improved home care may be all that is needed. The periodontist will track measurements over time to ensure the recession is stable.
When recession is moderate or progressing, gum grafting is the primary surgical treatment. A gingival augmentation procedure involves placing tissue, either from the roof of your mouth or from a donor source, over the exposed root area. A 25-year follow-up study published in the Journal of Periodontology found that gingival augmentation procedures maintained stable gum dimensions over decades when combined with proper maintenance. [4]
Other options in specific cases include guided tissue regeneration and the use of enamel matrix proteins to encourage tissue regrowth. Your periodontist will explain which approach fits your situation based on the location, depth, and cause of your recession.
Recovery After Gum Grafting
Recovery from gum grafting typically takes one to two weeks for initial healing. You will eat soft foods for the first week and avoid brushing the treated area until your periodontist clears you. Mild discomfort is normal and usually managed with over-the-counter pain medication.
Full tissue maturation takes several months. During this time, the grafted tissue integrates with your existing gum tissue and stabilizes around the tooth. Follow-up visits allow the periodontist to monitor healing and adjust your care plan.
Cost of Recession Treatment
Costs for recession treatment vary widely depending on the type of procedure, the number of teeth involved, your location, and your provider.
A periodontal evaluation and consultation typically ranges from $100 to $300. Gum grafting procedures generally range from $600 to $1,200 per tooth, though multi-tooth cases may be priced differently. Costs vary by location, provider, and case complexity.
Dental insurance often covers a portion of gum grafting when it is considered medically necessary rather than cosmetic. Coverage depends on your specific plan. Call your insurance provider before treatment to ask whether periodontal soft tissue grafting is a covered benefit under your policy.
Many periodontist offices offer payment plans or work with third-party financing companies. Ask about these options during your consultation visit.
When to See a Periodontist
See a periodontist if recession is progressing, causing symptoms, or affecting multiple teeth. A general dentist can monitor mild, stable recession, but a specialist evaluation is appropriate in several situations.
- Visible root exposure: If you can see a yellowish area below the normal gumline on one or more teeth, root surface is exposed and at risk for decay. [2]
- Increasing sensitivity: Sensitivity to cold, heat, or touch near the gumline may indicate that recession has exposed the root surface, which lacks the protective enamel covering.
- Recession that is getting worse: If your dentist's measurements show recession increasing at follow-up visits, a periodontist can determine the cause and whether treatment is needed.
- History of gum disease: If you have been treated for periodontitis in the past, a periodontist can provide specialized maintenance to protect vulnerable areas. [6]
- Teeth that appear to be getting longer: This visual change is one of the most common signs of recession that patients notice on their own.
- A notch or groove near the gumline: This may indicate an abfraction lesion related to clenching or brushing forces, and a periodontist can evaluate the gum tissue in that area. [5]
