The average person will develop four wisdom teeth, but that is not always the case for others. Many people develop supernumerary teeth while others fail to develop some or all of their dentures altogether.
The average mouth will only comfortably hold 28 of the 32 dentils we are predisposed to have. Since the wisdom teeth are the last dentures to come in, there is often little room left to accommodate their size and anatomy.
It is quite possible that each one of your dentils will come in differently from one another. During your regular dental check-up, your dentist may take an x-ray to diagnose whether or not your dentures need to be removed.
This x-ray gives the dentist a clear view of the area around the teeth, to determine the type of extraction necessary for each wisdom tooth. When the dentist discovers a reason for you to have your dentures removed he will access the position of the teeth and how each root is formed.
Depending on his findings, your dentist will make the decision to perform the dentures extractions for you, or refer you to see an oral and maxillofacial surgeon for your teeth extractions. Most people require wisdom tooth extractions, for a number of reasons.
A common misconception about teeth is they must be removed. Wisdom dentures are generally removed because they are impacting, have developed an infection, are tilted sideways, or there is not enough room on your gums.
The most common reason for a referral to an oral surgeon is because of where the teeth are positioned and the difficulty level of the extraction. If you request general anesthesia, or IV sedation, you will likely be referred to see an oral surgeon.
Keep in mind that this procedure is done in your best interest. When followed accurately, the instructions given to you before your oral surgery and after your oral surgery will ensure that your recovery is as smooth as possible.
After the elected method of sedation has taken effect, the oral surgeon or dentist starts the procedure by numbing the molar and tissues in the area of the mouth where the dentures are located, with a local anesthetic. Sometimes the dentist requires additional x-rays the day of the procedure.
Once the patient is completely numb from the local anesthetic and the required x-rays have been taken, the dentist begins the surgical part of the procedure by removing the gum tissue that is covering the area where the tooth is located. If the wisdom tooth is impacted, an incision is made in the gum tissue, in order to access the molar.
The gum tissue is then pushed out of the way with a surgical instrument until the molar is visible. There is a good chance that an impacted tooth could be fully or partially covered in bone.
If there is bone covering the dentils, a high-speed hand piece is used to drill through, and remove the bone covering the molar. If the tooth has already erupted into your mouth, the dentist will loosen the connective tissue from around the wisdom tooth.
Once the impacted dentures are visible to the dentist, various surgical instruments are used to gently loosen the tooth from any connective tissue in the molar's socket. The use of the high-speed hand piece may be used on and off throughout the extraction.
It may be necessary for the dentist to cut the molar into sections before it is removed. This is done because the molar is at risk for breaking while it is being removed from the socket, which will make extraction more difficult.
Once the tooth is loose, or it has been completely sectioned, it is ready to be removed. The dentist will remove the tooth with a selection of surgical instruments that are designed to remove the molar from the molar's socket.
