Tooth decay is all too common in our time. This problem can persist for a variety of reasons. The key to dealing with it is prevention, and in order to prevent tooth decay, you need to attend half year checkups, and also take care of your teeth at home with a rigorous daily routine.

Living for a long time and having good teeth seem to be inextricably linked together in many ways. Sometimes it is unclear whether the longevity is caused by good oral health, or if this person is just really healthy, and thus has good teeth.
The colour of our teeth is determined at birth by the colour of our dentine. Dentine plays such an important role in determining our tooth colour because the enamel that is on top of it is a chain of minerals, and is more or less colourless.
The weirdest things have been used to create new materials, and frequently researchers turn to nature when the time comes to invent something new. This time around, the feelers on squid tentacles were the subject of human thought, and some rather interesting potentials have been unlocked.
