Your dentist has spotted something that might sound alarming — a cavity on the root surface of your tooth. This is actually one of the most common dental issues, especially as we get older and our gums start to recede.

The root of your tooth normally sits safely below the gum line, protected by bone and soft tissue. When gums pull back, the root surface becomes exposed. This root cementum is softer than enamel, which means cavities can form there much more quickly.

Several things work together to create this problem. Gum recession is the main trigger, and that can happen from brushing too hard, periodontal disease, or simply from aging.

When the root is exposed, plaque bacteria settle onto the cementum surface. These bacteria produce acids that eat away at the root structure. Unlike enamel, the root has no protective layer once exposed — so decay can spread fast.

Dry mouth is another big factor. Saliva naturally helps wash away bacteria and neutralise acids. If you take medications that cause dry mouth, or if you simply don't produce enough saliva, your risk goes up significantly.

Treatment depends on how advanced the decay is. If it's caught early, your dentist can apply a fluoride varnish or prescription toothpaste to help remineralise the surface and stop it progressing.

For more established cavities, a dental filling is needed. Your dentist will remove the decayed portion of the root and replace it with a restorative material. This might be a composite resin, glass ionomer, or in some cases an amalgam.

In situations where the decay is extensive and has reached the pulp, root canal treatment or even extraction might be necessary. That's why catching it early matters so much.

The good news is this type of decay is very preventable. Fluoride is your best friend here — it helps strengthen the root surface and makes it more resistant to acid attacks.

Brush twice daily with a fluoride toothpaste, and don't rinse your mouth vigorously after brushing. Just spit out the excess paste. This leaves a thin layer of fluoride behind to protect your teeth.

Floss daily to remove plaque from areas your toothbrush can't reach, especially along the gum line. If you have gum recession, your dentist might recommend a special remineralising toothpaste for daily use.

Regular dental check-ups are essential, because root surface caries can develop silently without any pain until it's quite advanced. Your dentist can spot the early signs and intervene before it becomes a bigger problem.

If you're worried about root surface caries, or if it's been a while since your last dental visit, get in touch. Early detection and treatment is always simpler and more comfortable than waiting.
