Your gums are receding and you've heard dental bonding can cover the exposed root surface. You're wondering if this is actually a solution — or if it will make the problem worse. Here's what dentists actually think about using composite bonding for gum recession.

Gum recession happens when the gum tissue pulls back from the tooth, exposing the root. This is often caused by gum disease, aggressive brushing, teeth grinding, or simply genetics. Once the root is exposed, your tooth becomes sensitive to hot and cold. The exposed area is also more vulnerable to decay.

Addressing the underlying cause is always the first step. If you don't stop the recession, any treatment you have will eventually fail.

Yes, composite bonding can be applied to cover exposed root surfaces. Your dentist places tooth-coloured resin over the receded area, protecting it and reducing sensitivity. It won't regenerate your gum tissue, but it does create a barrier between the sensitive root and the outside world.

The bonding is matched to your natural tooth colour, so it blends in. For many patients, this is a quicker and less invasive option than surgical gum grafting.

Bonding over gum recession typically lasts 3 to 5 years. The exact lifespan depends on where the bonding is placed, how well you care for your teeth, and whether your recession continues. If your gums keep receding, the bonding may separate from the tooth root at the gumline.

This is one of the key limitations. Bonding covers what's already receded — it doesn't stop further recession from happening.

Gum grafting is the gold standard for treating significant recession. A periodontist takes tissue from another part of your mouth and attaches it to the receded area. This restores the gumline properly and can stop further recession.

Orthodontic treatment can sometimes help by repositioning teeth to better support gum tissue. Your dentist may also recommend a night guard if grinding is contributing to your recession.

Bonding is a reasonable option when recession is mild to moderate, when the cause has been identified and managed, and when you want a quick, reversible solution. It's less appropriate if your recession is still progressing rapidly, or if the underlying gum disease isn't under control.

Your dentist will assess your situation and help you weigh up whether bonding makes sense for you — or whether a referral to a specialist would give you a better long-term result.
