Dental fillings for your cavities could soon be a thing of the past
Dental fillings may soon be left in the ash heap of history, thanks to a recent discovery about a drug called Tideglusib.
Developed for and trialled to treat Alzheimer’s disease, the drug also happens to promote the natural tooth regrowth mechanism,allowing the tooth to repair cavities.
Tideglusib works by stimulating stem cells in the pulp of teeth, the source of new dentine. Dentine is the mineralized substance beneath tooth enamel that gets eaten away by tooth decay.
Teeth can naturally regenerate dentine without assistance, but only under certain circumstances. The pulp must be exposed through infection (such as decay) or trauma to prompt the manufacture of dentine.
But even then, the tooth can only regrow a very thin layer naturally—not enough to repair cavities caused by decay, which are generally deep. Tideglusib changes this outcome because it turns off the GSK-3 enzyme, which stops dentine from forming.
