Dentists drills could also soon be made redundant. In a ground-breaking new discovery, embedded within either a soft gel or a flexible film, then placed beside a dental cavity, a new peptide encourages tooth cells to regenerate in about a month, eliminating the need to or drill deep into teeth.

Dental researcher Wenyuan Shi - University of California - claims to have found a way to permanently keep cavity-causing bacteria at bay by developing a mouthwash that kills the bacteria responsible for cavities, known as Streptococcus mutans.
He and colleagues studied how these bacteria interact within the micro-organism colonies that build up on the teeth as plaque, latching on to tooth surfaces and breaking down food debris into acids which eat away at the enamel and lead to cavities, gum disease and even tooth loss.

With their so-called Specifically-Targeted Antimicrobial Peptides targets cavity-causing bacteria are targeted without interfering with other mouth microbes, unlike most antibiotics that kill good as well as unwanted bacteria, STAMPS giving the good bacteria develop a type of protection.

12 participants used the mouthwash once daily over a four-day trial, resulting in lower levels of bacteria, less lactic acid and a demineralization decrease into the bargain. Though as yet unclear in terms of price this revolutionary new anti-microbial treatment could potentially really rid us of of tooth decay.

Through 2012, the mouthwash will undergo more trials, though as it has no affect other bacteria, brushing to remove excess plaque will still be needed. Another general concern may be that people with open wounds in the mouth could introduce cavity-causing bacteria to the bloodstream, and travel to the heart, potentially causing infective endocarditis, fatal in some people.
University of Rochester researchers discovered more clues to answer why certain strains bacteria have a greater ability to invade the heart, if allowed so to do. It is known that four types of S. mutans exist in the mouth, some responsible for endocarditis through use of the CNM protein.

Disabling the CNM-producing gene enabled the team to prove that the bacteria were then less unable to sustain heart cell colonies, suggesting that CNM makes them better equipped to overcome the immune system, so that those with underlying heart conditions and artificial heart valves may be at greater risk during dental surgeries.
The body immune systems usually stop such bacteria immediately they are detected in the bloodstream, though microbes can survive in other body areas even in healthy people. It is hoped that research could help create a screening tool.

Dentists drills could also soon be made redundant. In a ground-breaking new discovery, embedded within either a soft gel or a flexible film, then placed beside a dental cavity, a new peptide encourages tooth cells to regenerate in about a month, eliminating the need to or drill deep into teeth.

Unlike toothpaste, claims Institut National de la Sante et de la Recherche Medicale scientist Nadia Benkirane-Jessel, the research aims at controlling cavities after they have developed. Dentists fill millions of cavities annually around the globe, the drill sound dreaded by many patients.
This new research shows that, instead of a drill, an infected tooth could heal teeth from within with a quick dab of gel or a thin film. Containing a peptide dubbed MSH - melanocyte-stimulating hormone - this encourages bone regeneration, so could potentially be useful for other treatments of damaged bone, as bone and teeth are fairly similar.
Itshould be remembered that MSH-containing films or gels only treat cavities, not preventing them, so mouth care will still need to be ongoing Clinical trials over the next few years means that MSH-containing gels will be unavailable to treat cavities in humans for some time yet.
