Impacted wisdom tooth are the third molars at the back of the 
mouth that do not have enough space to develop or emerge 
normally. They result in damage to other teeth, pain and other 
dental problems. In few cases these teeth may not cause any 
apparent problems but they are hard to clean and are more 
vulnerable to gum disease and tooth decay compared to other 
teeth.
Causes: The main causes for impacted tooth are as follows:
•Wisdom tooth becomes impacted when they do not have enough 
space to develop normally.
•An impacted wisdom tooth may partially emerge where the crown 
will be visible (partially impacted) or it never break through the 
gums (fully impacted).
•A partially impacted tooth can trap plaque, food and other debris 
in the soft tissue present around it which can lead to tenderness of 
gums, inflammation and unpleasant mouth odor.
•The retained plaque, debris may lead to the decay of neighboring 
tooth or wisdom tooth.
•Impacted tooth pushes on next tooth which in turn pushes the 
next tooth eventually causing misalignment of the bite.
Symptoms: Impacted-wisdom-tooth when infected and damages 
other teeth show certain signs and symptoms such as:
•Bad breath
•Prolonged jaw ache or head ache
•Tenderness or pain of the jaw bone or gums
•Difficulty in opening the mouth
•Swelling or redness of the gums around the impacted tooth
•Swollen lymph nodes of the neck (seen occasionally) etc.
Complications:
Formation of cysts: Wisdom tooth develops in a sac within the 
jawbone. This sac can fill with fluid thus forming a cyst that can 
damage the nerves, jawbone and teeth. This complication 
requires the removal of bone and tissue.
•Gum disease: The difficulty in cleaning the partially emerged 
wisdom tooth increases the risk of developing inflammatory, 
painful gum condition called pericoronitis in that area.
•Damage to neighboring teeth: In case where the wisdom tooth 
pushes the second molars it may damage or increase the risk of 
infection in that particular area. The pressure developed can also 
cause complications with crowding of the other teeth or may 
require orthodontic treatment for straightening other teeth.
•Tooth decay: Partially impacted teeth will be more prone to tooth 
decay than other teeth.
Treatment:
•No treatment is needed if the impacted tooth is not causing any 
problems.
•Pain relievers helps if the impacted tooth causes any discomfort.
•Extracting one’s tooth is one treatment if the impacted tooth 
cause pain or infects/ interferes with the neighboring teeth.
•Before removing the tooth, the patient will be made understand 
regarding the sedatives and anesthetics that will be used by the 
dentist or surgeon.
•The patient is recommended not to eat at least 6 hours before 
surgery.
•After the surgical treatment the patient may have swelling of jaw 
and cheeks.
