Luckily, with modern medical technology, teeth extractions are not so terrifying as they used to be couple of decades ago. I am not talking about that the delaying a tooth extraction is more harmful to your health than in fact making the dental appointment.
There are numerous of reasons which can make a person venture to a tooth extraction (when a qualified dentist removes a tooth from its socket in the bone), such as impaction for instance, which happens when a tooth starts to grow in without the room; that's actually the reason why most wisdom teeth require dental extraction, as they are naturally positioned to grow in without the space to grow into.
