Media interest in new toothpaste technology

The recently released Regenerate toothpaste made by Unilever, is based upon scientific studies conducted in Warwick Electrochemistry and Interfaces group. The new toothpaste has been causing quite a stir in the media, with articles being published on the toothpaste by UK newspapers such as the Telegraph and the Daily Mail. Futher the work was featured in Nature.

The paper published in the Journal of Dentistry, found here, uses several methods such as SECCM and raman to show that hydroxylapatite (HAP) was formed from calcium silicate. Deposition studies demonstrated greater delivery of calcium silicate to acid eroded than sound enamel and that the volume of acid etched enamel pits was significantly reduced following one treatment (p<0.05). In the protection study, the intrinsic rate constant for calcium loss from enamel was 0.092±0.008 cm/s. This was significantly reduced, 0.056±0.005 cm/s, for the calcium silicate treatments (p<0.0001).

It can therefore be concluded that calcium silicate can transform into HAP and can be deposited on acid eroded and sound enamel surfaces. Calcium silicate can provide significant protection of sound enamel from acid challenges.
