Smile! Researchers have found a natural alternative to painful tooth fillings

Here’s something to smile about: Researchers discovered a drug that enhances a tooth’s natural ability to regrow and repair itself, The Guardian reports. In tests on mice, the drug, tideglusib, successfully triggered stem cells that are located in the soft pulp center of a tooth to restore a tooth’s original dentine (the thick, hard layer of tooth material beneath enamel) where damage was located, according to the paper published today in Scientific Reports. Tideglusib, initially meant for Alzheimer’s patients, has already passed clinical safety trials, which could mean this treatment will hit the market sooner rather than later.
