can receding gums grow back

This is one of the most searched gum questions, and also one of the most exploited. Social media is full of products claiming to "regrow" gums in weeks. They do not. Once gum has pulled back and exposed part of the root, the body does not rebuild it by itself. The good news is that recession usually progresses slowly, it can very often be stopped, and some of it can be repaired surgically when that is worth doing.

Why gums recede in the first place

Recession means the gum margin has moved down the tooth, so the tooth looks longer and the yellowish root surface shows. The main causes are:

• Brushing too hard, especially sideways with a medium or hard brush. This often affects the canines and premolars on the side of your dominant hand.
• Gum disease (periodontitis), where infection destroys the bone that supports the gum. The gum follows the bone down.
• Tobacco held in one place, such as gutkha, kharra or mishri. The gum next to where it is kept often shrinks and hardens.
• Thin gums and thin bone, which some people are simply born with, particularly over the front lower teeth.
• Tooth position, including teeth pushed outward by crowding or moved during orthodontic treatment.
• A tight frenum (the small band of tissue joining lip to gum) that pulls on the gum edge.
• Grinding and clenching, which may contribute in some people, although the evidence is mixed.

What can genuinely be done

Stop the cause. Switching to a soft brush with a gentle technique, treating gum disease with a professional cleaning, and stopping tobacco are the most important steps. Without these, any repair will recede again.

Protect the exposed root. Root surfaces are softer than enamel. They become sensitive to cold and decay more easily. A fluoride or sensitivity toothpaste helps, and a small tooth-coloured filling can protect a notch worn into the root near the gumline.

Consider a gum graft. A periodontist (a dentist with an MDS in gum treatment) can move or graft gum tissue, often from the palate, to cover part of an exposed root. Results depend mainly on the level of bone and gum between the teeth. Where that is still intact, a good amount of coverage is often possible. Where it has already been lost, as in advanced gum disease, full coverage is not realistic. Grafting is usually done for sensitivity that does not settle, recession that keeps progressing, very thin gum, or appearance in the smile zone.

When repair is not worth it

Many people have mild, stable recession that never causes trouble. If it is not sensitive, not getting worse and not visible when you smile, careful monitoring is often the right answer. Ask your dentist to record the measurements, so you both know at the next visit whether anything has changed.

How we approach it

Your dentist will measure the recession, check the bone on an X-ray, and look for the cause before recommending anything. If a graft might help, you will be referred to our MDS periodontics department for an opinion. More on causes and treatment is on our gum recession page.
