The main goal of dentistry is to preserve your natural teeth and keep them healthy for as long as possible. There are times, however, when it is in your best interest (or your child's) to have a tooth extracted (removed). This could be the case for a variety of reasons. Perhaps you have a tooth that has been severely damaged by trauma or decay; or an impacted wisdom tooth that may cause trouble for you later on. Maybe your teenager will soon undergo orthodontic treatment and has insignificant space for his adult teeth, referred to as crowding. Or your younger child has a baby tooth that's stubbornly adhering, even though it's past time for it to go.
Whatever the reason, tooth extraction is more often than not a very routine procedure. How straightforward this minor surgery is will depend on where the tooth to be extracted is located in the mouth, and what its roots are like. For example, a front tooth with a single straight root is easier to remove than a molar with multiple roots. This is especially true when that molar is a wisdom tooth that is impacted, meaning it is below the surface surrounded by gum tissue and bone. Often, a wisdom tooth is blocked from fully erupting (growing in) by other teeth in its path.
Still, tooth extraction is nothing to be feared when done by an experienced hand. Keep in mind that a tooth is not rigidly fixed in its surrounding bone, though that's how some may picture it. In fact, it is attached to the bone via a network of fibers that form what's known as the periodontal ligament. By carefully manipulating the tooth, these fibers can be detached and the tooth freed without much trouble.
