Extraction of Impacted Teeth
If a tooth fails to emerge, or emerges only partially, it is considered to be impacted. Wisdom teeth, also known as third set of molars, usually become impacted. An impacted tooth gets stuck in gum tissue or bone mostly because the jaw is overcrowded and there’s no enough space for the teeth to emerge. Third molars could also get impacted if it has an improper path of eruption.If the wisdom teeth remains impacted or decayed and/or causes pain due to these reasons or otherwise they need to be removed. Some wisdom teeth that gets stuck in the gum without erupting completely can irritate and cause pain. In this case too the tooth must be removed. A partially emerged tooth can trap food, plaque, and other debris in the soft tissue around it, leading to inflammation and tenderness of the gums leading to pain and bad breath.
