Receding gums happen when the gum tissue around your teeth pulls back and exposes the tooth root. Lost gum tissue doesn't grow back on its own, but in most cases you can stop recession from getting worse — and the sooner you act, the more of your gum line you keep.
This guide covers everything in one place: what gum recession is, what causes it, the signs to watch for, how to prevent it, and the treatment options that actually work. It's meant to help you understand what's going on, not to replace a hands-on exam.
What are receding gums?
Gum recession is when the gum tissue that hugs each tooth pulls back, exposing more of the tooth and eventually its root. The root doesn't have the hard enamel that protects the rest of the tooth, which is why recession often brings sensitivity and, over time, a higher risk of decay. Because it usually happens slowly, many people don't notice it until a dentist measures their gums and points it out.
What causes receding gums?
Recession usually comes down to a handful of causes, and often more than one at the same time. Since the fix depends on the cause, this is the most important thing to figure out.
Gum (periodontal) disease
This is the leading cause. When plaque and tartar build up below the gum line, they trigger an infection that gradually breaks down the gum tissue and the bone that holds your teeth in place. As that tissue is lost, the gums pull back. Early gum disease is often painless, so it can progress quietly. Our guide to whether gum disease can be reversed explains each stage.
Brushing too hard
Scrubbing with a hard-bristled brush or heavy pressure physically wears gum tissue away over time. It's one of the most common causes in people who otherwise take good care of their teeth, and one of the easiest to fix.
Genetics
Some people inherit thinner, more delicate gum tissue that's more prone to receding, even with good care. If a parent had recession, you may be more susceptible.
Teeth grinding and clenching
Grinding (bruxism) puts repeated stress on the teeth and the gums around them, which can speed up recession. It often happens during sleep, so many people don't know they do it until a dentist spots the wear.
A misaligned bite
When teeth don't line up evenly, some take more force than others when you chew, and that uneven pressure can contribute to recession around the overloaded teeth.
Tobacco use
Smoking and smokeless tobacco raise the risk of gum disease and recession, and they also reduce the bleeding that would normally warn you something's wrong.
Signs of receding gums
Recession tends to show up as small, easy-to-miss changes long before it hurts. Watch for:
- A tooth that looks longer than its neighbors
- A small notch or step you can feel where the gum meets the tooth
- New sensitivity to hot, cold, or sweet foods
- A gum edge that seems to be lifting or pulling away from a tooth
- Bleeding, tenderness, or persistent bad breath
- A tooth that feels slightly loose
'My gum is coming away from a tooth'
That pulling-away feeling is a classic description of recession, and sometimes of the gum inflammation that comes before it. Healthy gums fit snugly around each tooth. When plaque builds up along the gum line, the tissue can become inflamed and start to detach, forming a small pocket where bacteria collect. If you can see or feel a gum edge lifting, have it checked before the pocket deepens.
Receding gums on one tooth or molar
Recession doesn't always affect the whole mouth evenly. It's common to notice it on a single tooth first. Localized recession usually has a local cause: heavy brushing pressure on one side, a tooth slightly out of alignment, the edge of an old filling or crown, or grinding that loads one tooth more than others. Because the cause is local, the fix often is too.
When gums look like they're 'decaying'
Gums don't decay the way teeth do, but active gum disease can make them look dark, puffy, and unhealthy — and the exposed roots left by recession are more prone to decay than enamel. A gum line that looks unhealthy alongside recession usually means active gum disease that needs treatment, not something to wait out.
How fast do gums recede?
There's no single answer. For many people recession develops slowly over years. When active gum disease or heavy grinding is involved, it can move noticeably faster. If your gums seem to be receding quickly, have them checked promptly, because rapid recession usually points to an active cause that will keep going until it's treated.
Can receding gums grow back?
No — and it's worth being clear, because there's a lot of misinformation online. No toothpaste, mouthwash, oil pulling routine, or supplement will regrow gum tissue. Those products may help with sensitivity or overall gum health, but they don't reverse recession. What genuinely helps is removing the cause and, where needed, having a dentist restore the tissue.
How to stop receding gums: treatment options
You can almost always halt or slow recession. Here's how treatment generally breaks down by severity.
Mild recession: remove the cause and monitor
If recession is early and there's no active gum disease, the goal is to stop whatever is causing it and keep an eye on it. That often means a soft-bristled brush and gentler technique, a desensitizing toothpaste for comfort, a nightguard if you grind, and regular cleanings so your dentist can track whether the gum line is holding steady.
Moderate recession: treat the gum disease
When recession is tied to gum disease, the gums won't stabilize until the infection below the gum line is addressed. The usual treatment is a deep cleaning — scaling and root planing — which removes the bacteria and tartar in the pockets around the roots so the gums can heal. Learn more about what a deep cleaning involves.
Advanced recession: gum grafting
For significant recession — where the root is heavily exposed, sensitivity is severe, or the tooth's support is at risk — your dentist or a periodontist may recommend a gum graft or a similar procedure to cover the exposed root and rebuild the gum line. A dentist can tell you whether you're a candidate after an exam.
How to prevent receding gums
Because lost tissue doesn't come back, prevention is the easiest way to keep a healthy gum line. The biggest causes are things you can influence:
- Brush gently. Use a soft-bristled brush at a slight angle to the gum line with light, short strokes. If your bristles flatten, you're pressing too hard. An electric brush with a pressure sensor can help.
- Floss daily and keep up with cleanings. Plaque and tartar along the gum line drive gum disease. Professional cleanings remove what you can't reach at home, and most people with healthy gums do well with a checkup and cleaning about every six months.
- Protect against grinding. If you wake with a sore jaw or your dentist sees wear, a custom nightguard protects both teeth and gums.
- Skip tobacco. Quitting is one of the most protective things you can do for your gums.
- Know your risk. Genetics and hormonal changes can make gums more vulnerable. If that's you, be extra consistent and see your dentist regularly.
When to see a dentist
See a dentist if you notice any of the signs above — especially if recession comes with bleeding, tenderness, bad breath, or a loose tooth, which can signal more advanced gum disease. A dentist can measure your gum pockets, identify the cause, and recommend the least invasive option that will actually stop it.

Frequently asked questions
What are receding gums?
Receding gums, or gum recession, is when the gum tissue around a tooth pulls back and exposes more of the tooth and eventually its root. It usually happens gradually, so a tooth looking longer, a small notch at the gum line, or new sensitivity are often the first clues.
What causes receding gums?
Gum (periodontal) disease is the most common cause, followed closely by brushing too hard. Genetics, teeth grinding, a misaligned bite, and tobacco use also contribute, and often more than one factor is involved. Finding the specific cause is the key to stopping it.
What does the start of receding gums look like?
Early recession usually shows up as a tooth that looks slightly longer than its neighbors, a small notch or step at the gum line, or new sensitivity to hot and cold. It's often subtle enough that a dentist spots it before you do.
Why is my gum receding on just one tooth?
Recession on a single tooth usually has a local cause at that spot, such as heavier brushing pressure, a tooth slightly out of alignment, the edge of an old filling or crown, or grinding that overloads that tooth. A dentist can pinpoint which it is and address it directly.
Can receding gums grow back?
No. Once gum tissue has receded, it doesn't grow back naturally, and no toothpaste, rinse, or supplement can regrow it. You can stop recession from getting worse by addressing its cause, and if the exposed root needs to be covered, a dentist can restore it with a gum graft.
How do you stop receding gums from getting worse?
Start by removing the cause: switch to a soft-bristled brush and a gentle technique, keep up with flossing and regular cleanings, and address teeth grinding or tobacco use. If gum disease is present, a deep cleaning to treat the infection below the gum line is usually what stabilizes the gums.
How fast do gums recede?
It varies. Recession is often gradual and develops over years, but active gum disease or heavy grinding can make it progress much faster. Noticeably rapid recession usually means there's an active cause that needs treatment.
Does a deep cleaning help receding gums?
When recession is driven by gum disease, yes. A deep cleaning (scaling and root planing) removes the bacteria and tartar in the pockets around the roots, which lets the gums heal and keeps the pockets from deepening. It won't regrow lost tissue, but it treats the infection causing the recession.
Can you prevent receding gums?
In most cases, yes. The leading causes — gum disease, brushing too hard, grinding, and tobacco use — are preventable or manageable. Genetics can raise your risk, but gentle brushing, daily flossing, and regular cleanings prevent most recession.
Is receding gums a serious problem?
It can be if it's left unchecked. Recession exposes the tooth root, which raises the risk of sensitivity, decay, and, in advanced cases, loss of the tooth's support. Caught early, it's very manageable, which is why it's worth having a dentist evaluate it.
