Gel Could Replace Cavity Fillings
A new gel or thin film is the latest technology to combat cavities. Instead of drilling a hole, removing the cavities and filling an infected tooth, a possible gel could heal the teeth from within.
This gel or thin film, consisting of a peptide known as MSH (melanocyte-stimulating hormone), has previously shown to encourage bone regeneration. Since bone and teeth are quite similar, the French scientists at the Institut National de la Sante et de la Recherche Medicale suggest that if MSH is applied to an infected teeth, it should regenerate the infected area of the tooth. They tested this theory by applying an MSH-contained film or gel onto a cavity-filled teeth of a mice. The results were successful as the cavities in the teeth disappeared.
However, tooth regeneration using MSH gel or film is only useful in a relatively small number of cases. The gel is used for treating cavities only, so you will still need to brush, floss and mouthwash to prevent cavities. [Discovery News]
