Alzheimer’s drug can encourage tooth regrowth in elderly – according to study

A drug used to fight Alzheimer’s disease has been found to naturally encourage tooth regrowth and repair, significantly reducing the need for fillings in elderly according to research.

Scientists from the Dental Institute at King’s College London have found a new way to generate Dentine (the outer material that protects the tooth from decay).

Following trauma or an infection, the inner, soft root of a tooth can become exposed and infected. To protect the tooth from infection, a thin band of dentine is naturally produced, but is insufficient to repair significant cavities.

The researchers found that the natural repair mechanism could be boosted if the Alzheimer’s drug was used.

Dentists currently use man-made fillings or cements, such as calcium and silicon-based products to treat larger cavities and fill holes in teeth.

This cement remains in the tooth and can fail to disintegrate, meaning that the normal mineral level of the tooth is never completely restored.

However, scientists believe this new approach could see teeth use their natural ability to repair large cavities rather than using cements or fillings, which are prone to infections and often need replacing.
