When dentists treat dental caries, they first remove the decayed part of the teeth and then fill it with materials to repair the defective teeth  However, 10% to 15% of the filling will fail, and the filler used does not have the function of self-healing teeth, and even has side effects  In view of this, researchers have developed a filler made of synthetic biomaterials, which can stimulate the growth of stem cells in dental pulp and repair the damaged part  This filler can stimulate the proliferation of stem cells and differentiate into dentin
If the filler for filling teeth in the future is made of such recycled materials, it will reduce the failure rate of filling teeth and reduce the pain of treating dental pulp in patients with tooth decay
The newly developed dental fillings can stimulate the self-healing of damaged teeth.
