With any dental problem, if it can be identified early on, it can be dealt with quickly, with the minimal of fuss and save you from complex treatments in the future. All problems in the mouth begin with plaque and acids on the surfaces of the teeth; these will start off tooth decay and then lead to caries forming in your mouth. Once these little beasts get a hold, they can infect the pulp and roots inside your teeth and then lead to tooth loss. The ways of detecting them however in surgeries throughout London W1 have got better: a toothache is the obvious sign you have a problem but even before this, if you keep up with dental appointments, your dentist has many ways to detect caries. The draconian way is to tap your teeth and if you flinch, you have a problem but a dentist will be able to see your teeth and will know straight away. The better way however is an x-ray and this will show up any problems immediately and thus you can get treated. In the meantime, dentistry has also come up with better ideas as well to help you detect such problems like caries at home; dyes can highlight the first signs of plaque, and thus caries, and by using techniques like these, you can protect yourself from major problems in the future.
