The advantages of an upper molar tooth extraction include reducing the risk for infection when teeth are decaying and providing additional space for an overcrowded mouth for teeth to move with orthodontic braces, states WebMD. Upper molars may also be removed to make room for incoming tooth growth.
The extraction of an upper molar tooth offers a significant advantage to people with severe tooth damage or trauma within the mouth, according to Nayda Rondon for the Consumer Guide to Dentistry. A tooth that is cracked, broken and beyond repair may cause infection within the mouth if not removed. People with advanced gum disease or loose teeth may also benefit from an upper molar tooth extraction to remove components of the disease or prevent portions of a tooth from cracking.
Upper molars that are malpositioned or nonfunctioning can have a negative effect on a person's oral health, explains Rondon. These teeth may cause discomfort when an individual is biting into food. The extraction makes room for additional tooth growth or room for false teeth to be inserted into the mouth.
When extracting upper molar teeth, dentists typically cut away bone tissue and gums covering the tooth and loosen the tooth from the jaw bone with forceps, notes WebMD. Some teeth may be removed in pieces.
