Reversing Tooth Decay by using electrical currents. No Drilling and No Fillings.

Today, Tooth Decay remains one of the most
common diseases throughout the world. Current treatment involves drilling the tooth to remove
decay and filling with restorative materials such as amalgam, resin, porcelain or gold. Trips to the dentist could soon be much less
painful as scientists are finding a way to repair tooth decay without the need for drilling
and fillings. Reminova Ltd, a new spin-out company from
King’s College London, is developing a new technique to achieve it. This technique effectively reverses tooth
decay by using electrical currents to boost the natural repair process of the tooth. It encourages teeth to repair themselves. The two-step method developed by Reminova
first prepares the damaged part of the enamel outer layer of the tooth, then uses a tiny
electric current to ‘push’ minerals into the tooth to repair the damaged site.
The defect is remineralised in a painless process that requires no drills, no injections
and no filling materials. Electric currents are already used by dentists
to check the pulp or nerve of a tooth; And, this new device uses lesser amount of electric
current which cannot be felt by the patient. The technique is named as Electrically Accelerated
and Enhanced Remineralisation (EAER). And, It will be available within three years. This method will be cost effective and can
also be used to whiten teeth. Around 2.3 billion people are believed to
suffer from tooth decay every year, making it one of the most common preventable diseases
in the world. The World Health Organization estimates that
60-90 percent of schoolchildren and nearly 100 percent of adults worldwide have dental
cavities.
