Let’s have a look at how the wisdom teeth are removed.
How Wisdom Tooth Is Removed?Removal of the wisdom tooth involves the following steps:
- Radiographic Evaluation – before starting with any dental surgical procedure, dentists first order various x-rays of the patient’s teeth, so as to assess the severity of the condition and to visualize any important structures, such as nerves, vessels and paranasal sinuses that may get damaged during the dental surgery. In addition, if it is an impacted wisdom tooth, radiographs are used to assess the positioning and angulation of the impaction.
- Administration of Anesthesia – if a single wisdom tooth is to be extracted, then the dentist may choose to administer a local anesthesia to the patient. However, in cases of very apprehensive patients or when multiple teeth are to be removed in a single sitting, wisdom teeth extraction is performed under the effect of sedation.
- Separation of the Attached Gums – Once the effect of anesthesia has fully set in, the first step in wisdom tooth removal is to separate the gums that are firmly adherent to the tooth. This is performed by an instrument known as a periosteal elevator.
- Removal of the Tooth – in order to loosen the wisdom tooth within its socket, it is gently rocked back and forth for a few times. Next, the dentist applies an upwards pressure while still rocking the tooth, until it comes out.
- Cleaning of The Extraction Socket – immediately after the wisdom tooth has been taken out, the extraction socket is first cleaned by thoroughly irrigating it with saline or water, so as to flush away a debris or tooth chips out of the socket. Next the dentist uses both the thumbs to squeeze the walls of the socket, and finally places a gauze over the tooth extraction site, and asks the patient to bite over it with pressure. This is performed to stop bleeding after wisdom tooth extraction and promote clot formation.
Wisdom Tooth Extraction, Cases Where Extended Surgical Procedure are required
Sometimes, the wisdom teeth are either too grossly carious, or are unfavourably angulated to allow the dentist a firm grip with the forceps. In these cases, there are chances that the wisdom tooth may fracture during the extraction, further complicating its removal. Therefore, the dentist may decide to perform some additional surgical procedure in order to ensure that a smooth and quick extraction. The rest of the procedure is the same as in the case of simple wisdom extraction:
- Incising the Gums – an incision is made into the gums, so as to gain a direct access into the underlying jaw bone.
- Removal of The bone – to be able to gain a direct access to the wisdom tooth, the dentist removes some of the jaw bone by drilling through, until the tooth becomes surgically accessible.
- Removal of the Wisdom Tooth – at this stage, the dentist can either choose to section the wisdom tooth into two halves to facilitate removal, or to try and remove it in a single piece.
- Suturing the Extraction Site – after cleaning and debriding the extraction socket, the gums are repositioned into their place, and then sutured.
A similar technique is applied for the removal of the Wisdom Teeth impacted teeth or other impacted teeth. However, since they are partially or completely embedded within the bone, extended bone removal and multiple tooth sections may be required before a tooth can be taken out.
