A study out of France has indicated it may one day be possible to fix cavities without drilling.
This is due to an experimental gel containing a substance that had been shown to help bones heal.
The gel or thin film contains a peptide known as MSH, or melanocyte-stimulating hormone. Previous experiments, reported in the Proceedings of the National Academy of Sciences, showed that MSH encourages bone regeneration.
To test their theory, the French scientists applied either a film or gel, both of which contained MSH, to cavity-filled mice teeth. After about one month, the cavities had disappeared, said Benkirane-Jessel.
This is certainly an interesting possibility, but the study also notes that it would only have limited usages, i.e. on very small cavities, and that no human trials have taken place. (At least at the time the study was published.)
Let me finish with a reminder you could expect was coming: keep up with your brushing, flossing, and check-ups – even if things like this come to pass, it’s much better to have no cavities at all.
