Recent research has shown that teeth can naturally repair themselves, which could help dentists adopt new practices in their clinics.

Scientists at King’s College London have been looking at whether activating cells to make more of the middle layer (dentine) could stimulate natural tooth repair. This follows previous findings that showed the drug Tideglusib could boost the production of dentine, which would help the inner layer of the tooth remain protected.

Professor Paul Sharpe, Dickinson Professor of Craniofacial Biology, led the study, which was published in the Journal of Dental Research.

As well as investigating the range of the drug and the viability of this practice, the scientists looked for evidence that this method could be used in clinical dentistry.

“In the last few years, we showed that we can stimulate natural tooth repair by activating resident tooth stem cells,” the professor stated.

He added: “This approach is simple and cost-effective. The latest results show further evidence of clinical viability and brings us another step closer to natural tooth repair.”

The researchers studied whether the volume of reparative dentine produced by the drug was sufficient to repair human cavities, and if its mineral composition is similar enough to normal dentine required for strong teeth.

The study found the repair area is restricted to the immediate location, the root pulp remains unaffected, and the drug can activate dentine damage of up to ten times the size, such as small lesions.

Important research developments such as these could alter clinical practice, which is why it is essential to have an up-to-date dental marketing strategy to respond to these ground-breaking changes as they happen.
