Receding Gums: Why Gums Pull Back and What Can Help

Receding gums are gums that have pulled back from the teeth, exposing part of the root that is normally covered. The most common causes are gum disease and brushing too hard, though grinding, tobacco, tooth position and your natural gum thickness all play a part. Gum tissue that has receded does not grow back by itself, but the process can usually be slowed or stopped, and a dentist can protect or cover exposed roots when needed.

Signs your gums may be receding

• Teeth that look longer than they used to
• A visible step or notch where the tooth meets the gum
• A yellower band near the gumline where the root shows
• Twinges with cold drinks, cold air or sweet food
• Small dark triangles opening up between teeth near the gums
• Food catching in new places

Sensitivity is often the first thing people notice, because the root surface is less protected than the crown. The guide to why teeth become sensitive explains what happens inside the tooth.

What causes gum recession

For people who smoke, gum problems can be easy to miss because bleeding, an early warning sign, may be less obvious. The article on smoker's teeth looks at how tobacco affects the mouth.

Why it can happen around just one tooth

Recession around a single tooth is common. It often points to something local: a tooth that sits slightly out of line, a spot that gets scrubbed harder because it is easy to reach, a piercing that rubs, or a tooth that takes heavier biting forces. A dentist can usually work out which applies by looking at the tooth and your bite.

Can receding gums grow back?

No. Once the gum has moved down the tooth, it does not return to its old position on its own, whatever toothpastes or rinses may promise. What you can do is stop it getting worse. Early recession often stays stable for years once the cause is dealt with, while recession driven by untreated gum disease tends to progress.

Everyday habits that protect your gums

1. Brush gently with a soft brush, using small circular movements rather than hard sideways scrubbing. An electric brush with a pressure warning can help heavy brushers.
2. Angle the bristles towards the gumline, where plaque gathers.
3. Clean between your teeth daily with floss or interdental brushes of the right size.
4. Use a fluoride toothpaste to protect exposed root surfaces, which decay more easily than enamel. Spit after brushing rather than rinsing, so the fluoride stays on the teeth.
5. Ask about a night guard if you wake with a tight jaw or have been told you grind.
6. Stop smoking, with support from a GP, pharmacist or stop-smoking service.
7. Keep regular check-ups, where gum health can be measured and tracked over time.

What a dentist may suggest

Treating gum disease

If inflammation is behind the recession, a thorough professional clean above and below the gumline is usually the first step, along with advice on home cleaning.

Protecting exposed roots

Desensitising varnishes, fluoride treatments or tooth-coloured filling material can cover sensitive or notched areas near the gumline.

Gum grafts

Where recession is more advanced, a specialist may move a small piece of tissue, often from the roof of the mouth, to cover the exposed root. This is a surgical procedure, and whether it suits you depends on the cause, the site and the health of the surrounding tissues.

Addressing the cause

That may mean changing brushing technique, wearing a guard, adjusting the bite or, in some cases, orthodontic treatment. If teeth are eventually lost, there are ways to replace them; the article on modern dental implants explains one option and why healthy gums matter for it.

When to book an appointment

See a dentist if you notice your gums pulling back, teeth looking longer, new sensitivity, bleeding when you brush, a bad taste or any loosening of teeth. Recession is far easier to manage when it is caught early, and a check-up is the simplest way to find out whether it is stable or changing.
