A tooth extraction may be necessary for many reasons, including severe damage or decay. One of the most common dental procedures, a tooth extraction can eliminate bacteria and improve your overall oral health.
Healthcare providers prefer to save natural teeth whenever possible. But sometimes, other restorative methods — such as dental fillings or dental crowns — aren’t enough. If your tooth has been badly damaged past the point of repair, then removal may be necessary.
Severe tooth decay (cavities).
A fractured tooth.
An impacted tooth.
Severe gum disease.
Tooth luxation or other dental injuries.
Wisdom teeth, or third molars, are the last permanent teeth to appear (erupt) in the mouth. These teeth usually appear between the ages of 17 and 25. Some people never develop wisdom teeth. For others, wisdom teeth erupt normally — just as their other molars did — and cause no problems.
Many people develop impacted wisdom teeth — teeth that don't have enough room to erupt into the mouth or develop normally. Impacted wisdom teeth may erupt only partially or not at all.
Grow at an angle toward the next tooth (second molar).
Grow at an angle toward the back of the mouth.
Grow at a right angle to the other teeth, as if the wisdom tooth is "lying down" within the jawbone.
Grow straight up or down like other teeth but stay trapped within the jawbone.
Trapping food and debris behind the wisdom tooth
Infection or gum disease (periodontal disease)
Tooth decay in a partially erupted wisdom tooth
Damage to a nearby tooth or surrounding bone
Development of a fluid-filled sac (cyst) around the wisdom tooth
Complications with orthodontic treatments to straighten other teeth
Therefore, it is always advisable to remove the wisdom teeth at the earliest to prevent any future complications.
