Researchers have developed new stem cell fillings allow your teeth to heal themselves- earning a prize from the Royal Society of Chemistry after judges called it a “new paradigm for dental treatments.”
New regenerative dental fillings have reportedly been developed by researchers- potentially eliminating the need for root canals. This earned a prize from the Royal Society of Chemistry, where judges described it as a “new paradigm for dental treatments.”
The New Treatment
Scientists at the University of Nottingham and Harvard University have created regenerative dental fillings, which allow teeth to heal themselves. The dental fillings stimulate stem cells to encourage dentin growth- the bony substance of which most of our teeth are made of. The drug in the dental filling is also known for treating Alzheimer’s disease.
“Existing dental fillings are toxic to cells and are therefore incompatible with pulp tissue inside the tooth,” said Adam Celiz, a researcher from the University of Nottingham. “In cases of dental pulp disease and injury a root canal is typically performed to remove the infected tissues.”
“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.”
How Exactly Would it Work?
Teeth are generally capable of regenerating a small amount of dentine, but not enough to regenerate the entire tooth back. This is why dentists drill further into the tooth before filling in your cavity. The dentine produced by the teeth over time seals the filling in place.
In this new method, the dentist would soak a biodegradable sponge with the Alzheimer drug and put it into the cavity. After six weeks, the stem cells will heal the tooth from the inside out.
