Teeth

Humans need teeth because they grind up food to be digestible. Teeth are the very start of the digestive system, chewing and biting food. There are different types of teeth including
- Canines, teeth which rip and tear up foods such as meat
- Molars, teeth that are wide and flat to grind and mash up food

Apart from the obvious reason of eating we even use teeth to show beauty and even to make certain sounds. Not very many people naturally have perfect sparkling white, straight teeth but this is what is desired. If someone was to have a beautiful face but they opened there mouth to a full set of brown crocked teeth they wouldn't be considered as pretty. Hollywood would have a big part to do with this, in every movie every movie star has perfect teeth, but it is seen as normal. If an actor playing a normal person on a film came on with not so perfect teeth they would be critisied and the audience would think it was part of their character to have those teeth. In Countries like Canada and the U.S you will find almost everybody had braces when they were young and now have perfect whitened teeth. But not so much in other countries where appearance isn't such a big deal, for example New Zealand.

Going to the dentist is something dreaded by all children, sitting in the waiting room looking around at all the different posters of teeth, smelling the distinct smell and hearing the drills is a terrifying experience. The dentist is mostly all around feared because of the fear of pain. Today there are injections to numb the gum and all sorts of fancy gadgets but in the past the dentist was a simple place with just tweasers and cotton buds. Back then there were no crowns or anything, once a tooth fell out a wooden one would be its replacement. The appearance of teeth weren't such a big deal back then, unlike today. Even in movies of the past where they had brown rotten teeth, movie stars have perfect pearly whites. I think teeth shouldn't be such a big deal, but how can one person make the change.

When a baby is six months to one year old its primary teeth will start to come through the gums, all together there should be 20 primary teeth. Commonly from the ages of six to fourteen these teeth will start to fall out and be replaced with 32 permanent (or adult) teeth. Later come the wisdom teeth which appear at 17 to 21 years of age, these are known to cause alot of pain and many people end up taking them out.
