Belfast scientists say aspirin could reverse tooth decay

Aspirin has long been prized for its painkilling properties, while low-dose aspirin is a popular systemic cardiovascular treatment, but new research shows that it could also reverse tooth decay.

According to a BBC report, the effects of tooth decay could potentially be reversed by the use of aspirin and lead to fewer fillings being needed in the future, researchers in Belfast have said. Tooth decay, the most common dental disease, leads to the inflammation of the tooth nerve, causing toothache.

Initial research at Queen’s University found aspirin stimulates stem cells in teeth, enhancing tooth regeneration. Current treatment for tooth decay involves fillings, which may need to be replaced many times during the lifetime of the tooth.

The British Dental Association reported in 2016 that 72% of 15-year-olds in Northern Ireland have dental decay. That figure compared to 44% in England and 63% in Wales.

Teeth naturally have limited regenerative abilities. They can produce a thin band of dentine, the layer just below the enamel, if the inner dental pulp becomes exposed, but this cannot repair a large cavity.

The research findings, to be presented later this week at the British Society for Oral and Dental Research annual conference, show that aspirin can enhance the function of those stem cells, thus helping self-repair by regenerating lost tooth structure.

The researchers collated large amounts of previous research data to identify aspirin as a compound that can induce the gene signature needed to generate new dentine.
