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.
If a tooth has been broken or damaged by decay, your dentist will try to fix it with a filling, crown or other dental treatment. But when there’s too much damage for the tooth to be repaired, the tooth may need to be extracted or removed from its socket in the bone.
Beyond damage and decay, here are some other common reasons for tooth removal:
1) Some people have extra teeth that block other teeth from coming in.
2) Sometimes baby teeth don’t fall out in time to allow the permanent teeth to come in.
3) People getting braces may need teeth extracted to create room for the teeth that are being
moved into place.
4) People receiving radiation to the head and neck may need to have teeth in the field of radiation
5) People receiving cancer drugs may develop infected teeth because these drugs weaken the
immune system. Infected teeth may need to be extracted.
6) Wisdom teeth, also called third molars, are often extracted either before or after they erupt in the mouth. They commonly come in during the late teens or early 20’s. They need to be removed if they are decayed, infected, or if there is not enough room in the mouth.
Why are Teeth Removed?
Teeth are extracted for a variety of reasons:
- Decay has reached deep into the tooth
- Infection has destroyed a large portion of the tooth or surrounding bone
- There is not enough room for all the teeth in your mouth.
How are Teeth Removed?
Before a tooth is removed, your dentist will thoroughly review your medical and dental history and take the appropriate X-rays.
X-rays reveal the length, shape, and position of the tooth and surrounding bone. From this information, your dentist can estimate the degree of difficulty of the procedure and decide whether to refer you to as specialist called an oral surgeon.
Before removal, the area around your tooth will be anaesthetised. Dentists use a local aesthetic to numb the area of the mouth where the extraction will take place.
For a simple extraction, once the area is anaesthetised, the tooth is loosened with the help of a tool called an elevator, then extracted with dental forceps. Your dentist may also want to smooth and re contour the underlying bone. When he or she is finished, they may choose to close the area with a
