Gum recession is when the gum tissue around a tooth wears back or pulls away, exposing more of the tooth and eventually its root. It is very common, with research suggesting a large majority of adults have some recession on at least one tooth. It matters because an exposed root is more sensitive, more prone to decay, and can make a tooth look longer. Recession cannot be reversed on its own, but in most cases it can be stopped from getting worse.
Key takeaways
- Recession exposes the softer root surface, which is why it often brings sensitivity to cold, heat, and sweet foods.
- The two biggest drivers are gum disease and overly hard brushing, though grinding, genetics, and tooth position also contribute.
- Gum tissue that has already receded does not grow back by itself, so the priority is halting further loss.
- Treatment ranges from changing your brushing technique and treating gum disease to gum grafting in more advanced cases.
- Catching it early, before the root is widely exposed, gives the simplest and most reliable outcome.
What causes gums to recede
Recession usually has more than one cause working together. Gum disease is the most common. When plaque bacteria are left along the gumline, the gums become inflamed and, over time, the supporting gum and bone are lost, which our guide to bleeding gums when brushing explains in more detail. Aggressive brushing with a hard bristled brush is the other major cause, physically wearing the delicate gum away, often seen as notches near the gumline. Other contributors include teeth grinding and clenching, which stress the gum margin, misaligned teeth or a thin gum type inherited from your family, smoking, and lip or tongue piercings that rub the gum.
The single rule that protects your gums
The most useful principle is that gentler is better. Gums are damaged both by too much force and by too little cleaning. The aim is thorough but soft daily cleaning: a soft bristled brush, light pressure, and cleaning between the teeth, rather than scrubbing hard in the belief that more force means cleaner teeth. Removing plaque gently every day protects against gum disease without wearing the tissue, and it is the single habit that does the most to prevent recession.
Signs and symptoms
The common signs are teeth that look longer than before, a small step or notch where the enamel meets the root, sensitivity to cold or sweet foods, and sometimes a visible darkening near the gumline as the root shows through. Some people notice food catching more, or that a tooth feels slightly loose in advanced cases. Because recession happens slowly, it is often first pointed out at a check-up before you notice it yourself.
| Cause | Typical clue | What helps |
|---|---|---|
| Gum disease | Bleeding, swollen gums, bad breath | Professional cleaning and gum treatment |
| Hard brushing | Notches near the gumline, thin gums | Soft brush, gentle technique |
| Grinding or clenching | Worn teeth, jaw tightness | Nightguard, bite assessment |
| Tooth position or thin gums | Recession on prominent teeth | Monitoring, sometimes grafting |
How gum recession is treated
Treatment depends on the cause and how advanced it is. The first step is always to remove the driver: a professional clean and gum therapy for gum disease, and coaching on a gentler brushing technique where hard brushing is the culprit. Sensitivity from exposed roots can be eased with a desensitising toothpaste, fluoride applications, or bonding to cover a worn notch, as our guide to enamel erosion and tooth wear discusses. Where recession is advanced or continuing, a gum graft can cover the exposed root by adding tissue, which reduces sensitivity and protects the tooth. Not everyone needs a graft, and the decision is based on symptoms, appearance, and whether the recession is stable.
Can receding gums grow back?
Once gum tissue has receded, it does not regenerate on its own. This is why the emphasis is on stopping further loss and, where needed, replacing lost tissue with a graft. The good news is that with the cause removed, most recession can be stabilised, and many people never need surgery. Acting early, while the exposure is small, keeps the options simpler.

When to see a dentist
Book a review if you notice teeth looking longer, new sensitivity, notches near the gumline, or gums that bleed when you brush. Early assessment identifies the cause and keeps treatment simple. For related reading, see our guides to bleeding gums, gum disease treatment, and preventing tooth decay, since exposed roots are more prone to cavities.
Frequently asked questions
Is gum recession serious?
Mild recession is common and manageable, but if it is driven by gum disease it can progress to loss of the bone that supports the tooth. That is why identifying and treating the cause matters.
Can I fix receding gums at home?
You cannot regrow lost gum at home, but switching to a soft brush, using a gentle technique, and cleaning between your teeth can stop it worsening. A desensitising toothpaste can ease the sensitivity.
Does gum recession mean I will lose the tooth?
Not usually. Most recession can be stabilised once the cause is treated. Tooth loss is a risk only when advanced gum disease is left untreated.
Will a gum graft last?
Grafts generally give durable coverage when the original cause, such as hard brushing or grinding, is also addressed. Keeping up gentle cleaning protects the result.
Why are my gums receding if I brush hard every day?
Brushing hard is one of the leading causes of recession, not a protection against it. Firm scrubbing wears the gum away, so a soft brush and light pressure are what your gums actually need.
