Regenerative dental fillings that allow teeth to heal themselves have been developed by researchers, potentially eliminating the need for root canals.
The treatment earned a prize from the Royal Society of Chemistry after judges described it as a « new paradigm for dental treatments. »
The tooth filling works by stimulating stem cells to encourage dentin growth. This is the bony material which makes up the majority of the tooth. Therefore, patients can effectively regrow teeth damaged through dental disease.
Adam Celiz, a research fellow from the University of Nottingham, describes the process, “We have designed synthetic biomaterials that can be used similarly to dental fillings but can be placed in direct contact with pulp tissue to stimulate the native stem cell population for repair and regeneration of pulp tissue and the surrounding dentin.”
