An amazing new technology to treat tooth decay has been discovered that actually involves growing new tooth tissue.
Many people dread going to the dentist, especially if they have a cavity that will require drilling and filling. They may put off the visit until the decay becomes so bad the tooth needs to be extracted. But now, all of that fear and pain may be a thing of the past.

Researchers at the University of Leeds in the UK have found an incredible new technology that appears to actually reverse the decay process and rebuild tooth tissue. Tooth decay begins when bacteria in your mouth produce acid. The acid dissolves the minerals and creates tiny holes or pores in the tooth. These holes get bigger with time, eventually turning into a large cavity.
The remarkable new cavity treatment uses a fluid that contains a peptide called P 11-4. When painted on a tooth that has early signs of decay, the fluid enters the little pores and forms a gel. The gel serves as a framework for calcium to attach to, rebuilding the tooth from the inside.
Professor Jennifer Kirkham of the University of Leeds Dental Institute describes the technique as, "a totally natural non-surgical repair process and is entirely pain-free too."
What a blessing this will be for people who suffer from tooth decay but are afraid of the dentist!

Painless Plasma Jets Could Replace Dentist's Drill
ScienceDaily (Jan. 20, 2010) — Plasma jets capable of obliterating tooth decay-causing bacteria could be an effective and less painful alternative to the dentist's drill, according to a new study published in the February issue of the Journal of Medical Microbiology.
Firing low temperature plasma beams at dentin -- the fibrous tooth structure underneath the enamel coating -- was found to reduce the amount of dental bacteria by up to 10,000-fold. The findings could mean plasma technology is used to remove infected tissue in tooth cavities -- a practice that conventionally involves drilling into the tooth.
Scientists at the Leibniz-Institute of Surface Modifications, Leipzig and dentists from the Saarland University, Homburg, Germany, tested the effectiveness of plasma against common oral pathogens including Streptococcus mutans and Lactobacillus casei. These bacteria form films on the surface of teeth and are capable of eroding tooth enamel and the dentin below it to cause cavities. If left untreated it can lead to pain, tooth loss and sometimes severe gum infections. In this study, the researchers infected dentin from extracted human molars with four strains of bacteria and then exposed it to plasma jets for 6, 12 or 18 seconds. The longer the dentin was exposed to the plasma the greater the amount of bacteria that were eliminated.
Plasmas are known as the fourth state of matter after solids, liquids and gases and have an increasing number of technical and medical applications. Plasmas are common everywhere in the cosmos, and are produced when high-energy processes strip atoms of one or more of their electrons. This forms high-temperature reactive oxygen species that are capable of destroying microbes. These hot plasmas are already used to disinfect surgical instruments.
Dr Stefan Rupf from Saarland University who led the research said that the recent development of cold plasmas that have temperatures of around 40 degrees Celsius showed great promise for use in dentistry. "The low temperature means they can kill the microbes while preserving the tooth. The dental pulp at the centre of the tooth, underneath the dentin, is linked to the blood supply and nerves and heat damage to it must be avoided at all costs."
Dr Rupf said using plasma technology to disinfect tooth cavities would be welcomed by patients as well as dentists. "Drilling is a very uncomfortable and sometimes painful experience. Cold plasma, in contrast, is a completely contact-free method that is highly effective. Presently, there is huge progress being made in the field of plasma medicine and a clinical treatment for dental cavities can be expected within 3 to 5 years."
