It's the main reason so many of us feel such trepidation when faced with a trip to the dentist.
But the dreaded drill could soon be a thing of the past thanks to a new technique in which teeth are treated with acid gel squirted from a syringe.
Although acid in food and drink is one of the biggest causes of decay, scientists say its corrosive properties become an advantage when it comes to removing rotting parts of teeth.
And while a drill can destroy healthy parts of the tooth, the makers of the pencil-sized 'Icon' syringe say their treatment is far more efficient at removing only the diseased area - and less traumatic.
First, a rubber 'collar' is placed around the target tooth to protect its neighbours. The four-inch syringe then applies a spot of the gel to the discoloured and decaying part.
Within a couple of minutes the acid etches through the enamel into the cavity below, which is then cleaned then dried using ethanol. FInally, the dentist injects a quick-drying resin into the hole which hardens quickly under a high-energy blue light.
The finished filling looks like normal tooth enamel and the whole process takes just 15 minutes.
Icon's developers say small areas of decay, or 'caries', can be treated early before they develop into large cavities, sparing patients more invasive treatment and discomfort.
The treatment has been developed by German company DMG Dental Products in conjunction with the University of
