Receding gums happen when the gum tissue pulls back and exposes more of the tooth or its root. The most common causes are gum disease and brushing too hard. Recession doesn’t grow back on its own, so the goal is to stop it getting worse — and see a dentist about your options.
What are receding gums?
Gum recession is when the gum margin pulls away from the tooth, exposing the root. Because roots are not protected by enamel, the first sign is often sensitivity to hot, cold, or sweet — along with teeth that look longer or a notch you can feel at the gumline.
What causes gum recession?
- Gum (periodontal) disease — the leading cause; infection destroys gum and bone.
- Brushing too hard or with a stiff brush — wears the gums down over time.
- Teeth grinding and misaligned bite — extra force on the gumline.
- Tobacco use and genetics — some people are simply more prone to it.
Can receding gums grow back?
No — receded tissue does not regenerate on its own. The realistic goal is to halt the progression: treat any gum disease, switch to a soft brush and gentle technique, address grinding with a night guard, and quit tobacco.
How dentists treat receding gums
Treatment depends on how far it has gone — from a deep cleaning plus improved home care, to a gum graft that covers exposed roots in more advanced cases. This is a call for your dentist. Preventing the gum disease behind it is covered in our gum disease guide.
When to see a dentist
If you notice sensitivity, visibly longer teeth, or gums pulling back, have a dentist evaluate it — catching recession early gives you the best chance to stop it.
