Have you noticed that your teeth look longer than they used to, or that the roots of your teeth seem more visible? You may be experiencing gum recession. This happens when the gum tissue surrounding a tooth gradually pulls back, exposing more of the tooth or its root.
Gum recession is relatively common, but it should not simply be ignored. It can make teeth sensitive, harder to clean and, depending on the underlying cause, may increase the risk of tooth decay and further gum problems. Gum disease is one of the important causes, but it is not the only reason gums can recede.
Understanding why your gums are receding can help you identify the problem early and get appropriate dental advice.
What Is Gum Recession?
Gum recession, also called gingival recession, occurs when the gum margin moves away from its normal position around the tooth. As the gum tissue recedes, part of the tooth root may become exposed.
Unlike the visible crown of a tooth, the root is not covered by protective enamel. This means an exposed root can be more sensitive and more vulnerable to decay.
Some people notice recession because their teeth appear longer. Others may first experience sensitivity when drinking something cold or eating hot, sweet or acidic foods.
Gum recession can affect one tooth or several teeth. It may develop slowly, so you might not notice it until a dentist examines your gums.
Why Are My Gums Receding?
There are several possible causes. Identifying the cause is important because treatment depends on what is contributing to the recession.
1. Gum Disease
One of the most important causes of gum recession is gum disease.
Plaque is a sticky film containing bacteria that continually forms on teeth. If it is not removed effectively, it can irritate the gums and cause inflammation. Early gum disease, known as gingivitis, can cause red, swollen or bleeding gums.
If gum disease progresses to periodontitis, the tissues and bone supporting the teeth can be damaged. As this support is lost, the gums may shrink or recede. Untreated periodontal disease can eventually contribute to loose teeth and tooth loss.
Signs that gum disease may be involved include bleeding when brushing, swollen gums, persistent bad breath, gum tenderness or loose teeth.
2. Brushing Too Hard
Brushing your teeth is essential for good oral health, but using excessive force can irritate or damage gum tissue.
Using a hard-bristled toothbrush or repeatedly scrubbing the same area aggressively may contribute to gum recession, particularly when the gum tissue is already thin.
A gentler approach is usually better. Use a soft-bristled toothbrush, fluoride toothpaste and controlled movements rather than pressing heavily against your teeth and gums. Aggressive brushing is recognised as one possible cause of gum recession.
3. Naturally Thin Gum Tissue
Not everyone's gums are the same thickness. Some people naturally have thinner gum tissue, which can make certain areas more vulnerable to recession.
The shape of the gums, teeth and surrounding oral tissues can also influence how susceptible an individual is to gum recession.
4. Poor Oral Hygiene
Inadequate plaque removal allows bacteria to remain around the gumline. Over time, this can contribute to gum inflammation and periodontal disease.
Brushing twice a day alone is not enough if plaque remains between the teeth. Cleaning between your teeth daily with floss or interdental brushes helps remove plaque and food debris from areas a toothbrush may not reach.
5. Smoking and Tobacco Use
Smoking can negatively affect gum health and is associated with an increased risk of periodontal disease. Tobacco use can also make it harder to maintain healthy gums.
If you smoke, speaking to a healthcare professional or dentist about stopping can benefit both your oral and general health.
6. Teeth Grinding or Clenching
Repeated pressure from bruxism, or teeth grinding and clenching, can put additional stress on teeth and their supporting tissues.
If you regularly wake with jaw discomfort, headaches, worn teeth or muscle tenderness, tell your dentist. They can assess whether grinding or clenching may be contributing to your dental problems.
7. Crooked or Crowded Teeth
The position of your teeth can influence how easily you can clean around them. Teeth that are crowded, rotated or positioned unusually may make effective plaque removal more difficult.
Certain areas may also have thinner gum tissue, which can make recession more noticeable.
What Are the Symptoms of Receding Gums?
Gum recession does not always cause obvious symptoms. However, you may notice:
-
Teeth appearing longer than before
-
Visible tooth roots
-
Increased tooth sensitivity
-
Sensitivity to cold drinks or foods
-
Discomfort when brushing
-
A notch or indentation near the gumline
-
Bleeding or swollen gums
-
Persistent bad breath
-
Difficulty cleaning around an exposed root
-
Loose teeth in advanced gum disease
If you have bleeding, swollen or painful gums, or your teeth are becoming loose, arrange a dental examination. NHS guidance recommends seeing a dentist when symptoms of gum disease are present.
Are Receding Gums Serious?
Gum recession is not necessarily an emergency, but it should be assessed because the cause can vary.
If periodontal disease is responsible, leaving it untreated can allow damage to the tissues and bone supporting your teeth to progress. An exposed root can also become more sensitive and may be more difficult to keep clean.
Recession itself does not automatically mean that you will lose the affected tooth. The long-term outlook depends on factors such as the amount of recession, gum health, bone support, oral hygiene and the underlying cause.
How Is Gum Recession Diagnosed?
A dentist will examine your gums and teeth to determine the extent and likely cause of the recession.
They may check:
-
The position of the gumline
-
Gum inflammation and bleeding
-
Plaque and tartar accumulation
-
The depth of gum pockets
-
Tooth sensitivity
-
Tooth mobility
-
The condition of exposed roots
-
The supporting bone around the teeth
Dental X-rays may sometimes be recommended when the dentist needs to assess the supporting bone or investigate periodontal disease.
The purpose of the examination is not simply to measure the recession but to identify why it is happening.
How Are Receding Gums Treated?
Treatment depends on the cause and severity.
Improving Oral Hygiene
If plaque and gum disease are contributing to recession, your dentist or dental hygienist may provide personalised oral hygiene advice.
This can include brushing twice daily with fluoride toothpaste and cleaning between the teeth every day. Professional cleaning may also be recommended to remove plaque and tartar that cannot be removed effectively at home.
Treating Gum Disease
If periodontal disease is responsible, treatment focuses on controlling the bacterial plaque and inflammation and protecting the supporting tissues.
More advanced gum disease may require professional treatment below the gumline, sometimes called deep cleaning or scaling and root surface treatment. The exact approach depends on the severity and individual circumstances.
Changing Brushing Technique
If aggressive brushing is contributing to recession, your dentist may recommend changing your brushing technique and using a softer toothbrush.
The goal is to remove plaque effectively without unnecessarily damaging the gum tissue.
Gum Grafting
In selected cases, a dentist or periodontist may recommend gum grafting.
During soft-tissue grafting, tissue is used to cover or protect an exposed root area. The procedure may help reduce sensitivity, improve gum stability and protect vulnerable areas. However, it is not suitable or necessary for every person with gum recession.
Can Receding Gums Grow Back?
In most cases, gum tissue that has significantly receded does not simply grow back naturally.
However, further recession may sometimes be prevented or controlled by treating the underlying cause. For example, improving plaque control, managing gum disease and changing an aggressive brushing technique can help protect the remaining gum tissue.
Where appropriate, periodontal or soft-tissue procedures may be considered to improve coverage or stability.
How Can You Prevent Gum Recession?
You cannot prevent every case of gum recession, particularly when factors such as naturally thin gum tissue are involved. However, good oral care can reduce several important risk factors.
A healthy routine includes:
-
Brush twice a day with fluoride toothpaste.
-
Use a soft toothbrush and avoid excessive brushing pressure.
-
Clean between your teeth every day with floss or interdental brushes.
-
Do not ignore bleeding gums or persistent swelling.
-
Attend regular dental check-ups.
-
Avoid smoking and tobacco products.
-
Have tooth sensitivity or exposed roots assessed by a dentist.
-
Follow professional advice if you have gum disease.
The NHS recommends brushing twice a day with fluoride toothpaste, cleaning between the teeth daily and attending regular dental check-ups.
When Should You See a Dentist?
Make a dental appointment if you notice that your gums are receding, particularly if the change is getting worse.
You should seek dental advice sooner if you also have:
-
Bleeding or very swollen gums
-
Persistent bad breath
-
Severe gum pain
-
Loose teeth
-
Increasing tooth sensitivity
-
Pus around the gums
-
Difficulty eating or chewing
-
Significant changes in the position of your teeth
Early assessment can help identify whether the problem is caused by gum disease, brushing technique, tooth position or another factor.
Frequently Asked Questions
Can brushing too hard cause receding gums?
Yes. Aggressive brushing can contribute to gum recession, particularly when the gum tissue is thin. Using a soft toothbrush and a gentle technique can help reduce unnecessary trauma.
Do receding gums mean I have gum disease?
Not necessarily. Gum disease is an important cause, but recession can also be associated with aggressive brushing, naturally thin gums and other factors. A dentist can determine the likely cause.
Can receding gums cause sensitive teeth?
Yes. When recession exposes part of the tooth root, the area can become more sensitive, particularly to cold, hot or sweet foods and drinks.
Can a dental hygienist treat receding gums?
A dental hygienist can help control plaque and tartar and provide personalised oral hygiene advice. If gum recession is related to periodontal disease, your dentist may recommend a wider treatment plan.
Is gum graft surgery always necessary?
No. Gum grafting is only appropriate for certain cases. Your dentist or periodontist will consider the cause, severity, symptoms and risk of further recession before recommending treatment.
Can gum recession be reversed naturally?
Receded gum tissue generally does not grow back on its own. However, addressing the cause can help prevent or reduce further progression in some cases.
Conclusion
If you are wondering, “Why are my gums receding?”, there may be more than one possible explanation. Gum disease, aggressive brushing, naturally thin gum tissue, smoking, tooth position and other factors can contribute to changes in the gumline.
The important step is to identify the underlying cause rather than treating the appearance alone. Maintaining good oral hygiene, using a gentle brushing technique and attending regular dental appointments can help protect your gums and teeth.
If you have noticed exposed roots, increasing sensitivity, bleeding gums or a changing gumline, arrange an examination with a dentist. Early assessment can help identify problems such as gum disease before they cause more extensive damage.
