Do you loathe going to the dentist and hearing the sound of that menacing drill? Well you'll be happy to know that the sound of the drill may be a thing of the past at the dentist's office. Researchers at King's College in London think they have found a way to encourage teeth to repair themselves. If it works, it will mean bye-bye to drilling and hello to healthier teeth without the anxiety.
The new technique uses electricity to strengthen teeth by forcing minerals into layers of the tooth's enamel. You may not realize it, but minerals such as calcium and phosphate are constantly flowing in and out of your teeth, but bacteria from lingering food produce acids that leech these minerals from the teeth. This is what causes cavities to form.
By combining a mineral cocktail with a little bit of electricity, researchers were able to drive the minerals deep into the tooth, strengthening it, and reducing the incidence of cavities.
It's all hush-hush and patent pending right now, so there aren't any published studies to confirm the veracity of these reports, but a company called Reminova hopes to create the technology to bring this technique — dubbed "Electrically Accelerated and Enhanced Remineralisation" — to a dentist chair near you within the next three years.
