Could aspirin repair tooth decay?

Researchers at Queen’s University, Belfast, have discovered that aspirin could offer an alternative solution to restoring a tooth affected by decay. The research findings, presented on September 7, 2017, at the British Society for Oral and Dental Research Annual Conference, show that aspirin can enhance the function of stem cells found in the teeth, thus helping self-repair by regenerating lost tooth structure.

The researchers combined genomics and novel bioinformatics to identify aspirin as a candidate drug with properties that stimulate existing stem cells in the tooth to enhance the regeneration of the damaged tooth structure. Treatment of stem cells from teeth with low-dose aspirin significantly increased mineralisation and the expression of genes responsible for forming dentine, the hard tooth structure that is usually damaged by decay. This novel discovery coupled with the known anti-inflammatory and pain relieving effects of aspirin could provide a solution for controlling tooth nerve inflammation and pain while promoting natural tooth repair.
