Teeth are extracted for a variety of reasons:
Decay has reached deep into the tooth
The infection has destroyed a large portion of the tooth or surrounding bone
There is not enough room for all the teeth in your mouth
Many dentists recommend extracting impacted teeth that are only partially erupted. Bacteria can enter around a partially erupted tooth and cause an infection, which can extend into the surrounding bone and become extremely serious. Impacted teeth continue trying to break through the gum tissue even if there is not enough room to accommodate them. The continued pressure caused by this attempted eruption can eventually damage the roots of nearby teeth. Removing a tooth that is impacted can often prevent infection, damage to adjacent teeth and bone, and save pain in the years to come.
Wisdom Tooth Extraction
Unlike normal teeth, extraction of wisdom teeth entails surgically cutting off the teeth. It is for this reason that patients are usually sedated in order to avoid feeling the pain. Then again, you have to follow a strict diet soon after the removal of your wisdom teeth in order to accelerate the healing process.
Normal Tooth Extraction
Removal of normal teeth does not require the services of an experienced and skilled oral surgeon as is the case with wisdom teeth. Normal teeth can easily be extracted by a general dentist or family dentist. During the extraction process, the dentist only needs to numb the area in order to minimize pain. Most people do not experience pain after the extraction of the normal tooth and as such, there is no need to prescribe painkillers.
