Extraction is needed mainly when the tooth has become so infected it can represent a danger to your overall health. In order to stop that infection from spreading further, the dentist will extract the tooth. Immediately after the area has healed it is important to get a replacement for the missing tooth, such as a dental crown or an implant.
The dental extraction is one of the most feared procedures, even though with today’s technology the patient will not feel anything during the procedure. There are numbing gels, injections, sedation dentistry (IV sedation, oral sedation available, so the patient will not feel or remember anything from the procedure.
Why and when teeth need to be extracted
In case of a bad dental abscess when the tooth cannot be saved even through root canal therapy, extraction is the last resort solution. At this point the infection has reached deep into the pulp of the tooth and the tooth needs to extracted, and the area cleansed properly. Then, in case of the children, the hanging baby teeth need to be pulled, because they hinder the growth of the permanent teeth from beneath.
In some rare cases, the orthodontist will suggest the extraction of the first and second premolars before applying the dental brace treatments. These extractions are needed, so that the neighboring teeth will have the necessary space to shift into place. Dental extraction before dental braces treatment is needed only when the teeth are extremely crowded, and it is impossible to straighten the teeth without such an extraction being performed.
Cancer patients who undergo chemotherapy treatments can also end up with badly infected teeth, and then extraction is the sole solution. Dental extraction is also advised in case of impacted wisdom teeth. However, dentists recommend extraction of impacted teeth especially if the impacted tooth causes a lot of pain and discomfort, or if infection is also present.
The removal of wisdom teeth requires surgical extraction, which means that the dentist will cut through the gum tissue, extract the tooth and then perform stitches. Recovery time is also much lengthier in case of wisdom teeth removal, and sometimes it can be extremely difficult to extract a wisdom tooth depending on its location and position of growth.
Some of the potential risks associated with dental extraction include accidental damages to teeth in the immediate vicinity (chipping of the enamel, breaking a fragment of the tooth, etc.), dental infections if the area has not been cleansed properly, post operative swelling, or a sinus hole. At times it may happen that the dentist performs an incomplete extraction and then the root of the tooth will be still attached to the alveolar bone.
