Wisdom Teeth
Friday, January 26th, 2007At around the age of 17, wisdom teeth either erupt—or try to, or fail entirely to erupt—in the back of your mouth. Because of the lack of room in the jaw for the large, sharp wisdom teeth, the dental community often encourages them to be removed. But why should you? Do your teeth need all that space? Or is there more to it than that?
When wisdom teeth come into your mouth fully, and not crooked, they’re usually harmless, and serve their purpose of being grinders. But it’s often the case that a tooth will only erupt halfway, leaving the pierced gum area around it susceptible to food and bacteria which can leak down inside and cause infection—not to mention bad breath. These infections aren’t small matters, although they do begin that way. If left untreated, they can cause trismus, the inability to fully open the mouth, and keep spreading until they reach as far as the neck. (more…)

The Wisdom teeth are the large molars at the end of each line of teeth - there is one Wisdom tooth at the end of each row - therefore there are 4 in total.
