Finding tooth decay early is one of the best things we can do for your teeth. The earlier we spot it, the more options you have, and some early decay can now be treated without a drill. Some early decay is hard to see by eye, even with the magnification our dentists use, so we also use AI software on your X-rays to help us spot these early changes and act sooner. This guide explains how we look for early decay at Pennington Dental in Kenilworth and Stratford-upon-Avon, and how Curodont treatment may help.
Tooth decay starts in the hard outer layer of the tooth, the enamel. At first, minerals are lost from the enamel without a hole (cavity) forming. You usually cannot feel it, and it can be hard to see, especially between teeth.
If it is left, decay can work its way through the enamel into the softer dentine underneath. At that stage a filling or other treatment is usually needed. Catching it while it is still in the enamel gives us the chance to treat it more gently.
At your check-up, your dentist examines your teeth and looks at your X-rays. Some early decay is hard to see by eye, even with the magnification (loupes) our dentists wear. To help with this, we use Pearl's Second Opinion software, which helps us spot these early changes on X-rays so we can act sooner. It is artificial intelligence (AI) software that reviews dental X-rays as they are taken and highlights areas that may need a closer look, including early decay, decay between teeth, tartar and bone loss.
The software uses colour to mark these areas, and can show the different layers of each tooth (enamel, dentine and pulp). This makes it much easier for us to show you what we can see, and for you to understand how far any decay has gone.
The AI is a support tool, not a replacement for your dentist. It acts as a second pair of eyes, and your dentist checks its findings, examines your mouth and makes the diagnosis.

Curodont Repair is a treatment for early decay that has not yet formed a cavity. It is a liquid that your dentist applies to the surface of the tooth, so the treatment itself needs no drilling or injections.
It contains a peptide that moves into the early lesion and forms a framework that attracts calcium and phosphate from your saliva. This helps the tooth rebuild early enamel decay using minerals from saliva. And because there's no drill, no injection and no filling to look after or replace later, treating decay early can mean real savings over a lifetime.
Curodont is provided by our dentists at both our Kenilworth and Stratford-upon-Avon practices.
Curodont is designed for early, non-cavitated decay in the enamel. If decay has already formed a cavity or reached the dentine, a filling or other treatment may be needed instead. Your dentist will decide at your examination whether it is suitable for you.
No treatment can be guaranteed. Curodont is used to help stop early decay from progressing, but results vary and it may not avoid the need for a filling in every case. Good brushing, a healthy diet and regular check-ups are still important.
The number of surfaces to be treated is confirmed at your examination, so you will know the cost before we start. Find out about the Pennington Plan.
The treatment is a liquid applied to the tooth surface, so there is no drilling and no injection is needed.
Possibly. Curodont is for early decay only, and it may not avoid a filling in every case. Decay that has already formed a cavity needs different treatment.
Early decay usually has no symptoms, which is why regular dental check-ups and X-rays when needed are so important.
No. The software highlights areas for your dentist to review. Your dentist makes the diagnosis and talks you through your options.
