A tooth extraction is considered to be the last resort treatment to a dental problem. It is usually reserved for cases when no other treatment is enough to solve the dental concern, and leaving the affected tooth in place may bring even more harm to the neighbouring teeth, gums, and surrounding structures. Whenever possible, the goal will always be to save a tooth from being removed or extracted, but that may not always be the case.
A tooth may be saved from extraction if a root canal can still repair the damage to the affected tooth. A root canal treatment is done to remove the damaged and decayed portions of the teeth and the tooth roots, which may be the result of a bacterial infection. Once the damaged portions have been removed, the roots will then be filled, and a dental crown is then used to protect the treated tooth from further infections or damage. A badly decayed tooth can be saved from being removed through extraction through the use of a root treatment, but in some cases, there is no other choice but to remove the damaged tooth.
Extraction is needed if a tooth has been badly decayed or damaged, or if it is impacted. An impacted tooth does not grow out properly from under the gum line and instead moves sideways, pushing against neighbouring teeth and causing severe pain. If a tooth is impacted, it has a higher risk of being decayed because it is difficult to keep it clean from its position under the gum line.
