Scientists from Queen Mary University of London have created a new material for dental fillings, which can treat tooth by itself. It can be inserted into teeth to repair and regenerate dentin – the hard, bone-like tissue that makes up the bulk of all teeth.
Professor Robert Hill told that innovative structure is a bioactive composite material on a glass base. It appears that after the dental filling is placed in the tooth cavity, minerals begin to be released, which form a tooth tissue, namely fluoride, calcium and phosphorus. According to this, dental tissue will be recovered.
Also, comparing to old tooth fillings, the new material leaves no gaps between filling and tooth, making impossible a bacterial growth under filling. At the same time scientists assure that this filling will be put once and forever. It will not be weared out over time, like modern tooth fillings, and certainly will not fall.
The technique just won second prize in the materials category of the UK Royal Society of Chemistry’s Emerging Technologies Competition 2016.
