Wisdom teeth are the third and final set of molars that emerge, usually during your late teens to early twenties. For some people the wisdom teeth emerge through the gums and have enough room to grow in naturally. For others, wisdom teeth often cause problems as they are trying to protrude through the gums. When a wisdom tooth is impacted the tooth is coming in at an angle and not straight through the gum line. This can cause pain, the tooth can come in unevenly, or the tooth may only emerge partially.
Impacted wisdom teeth can cause structural damage to the jaw and other teeth. They can also provide a place for bacteria to gather since they are hard to reach and clean. These potential problems make it necessary to remove impacted wisdom teeth so that larger problems do not arise. Routine x-rays during a dental exam can reveal if you will need to have your wisdom teeth removed.
Bone grafting is where the jawbone is built up to accommodate a dental implant or other restorative device. Bone grafting is a common procedure that is used frequently for dental implants and other periodontal procedures. The bone used to graph is taken from a sample from the patient. Many times, the bone is taken from another area of the mouth when drilling takes place. The bone fragments are suctioned from the mouth and used for the graft. Cadavers bone fragments are also used. They are harvested by bone banks and are a very safe source for bone donation.
