The procedure of getting a tooth removed from the mouth is called a tooth extraction. A professional dentist performs it at a dental practice under the influence of a sedative. Prior to extracting the tooth, we consider every possible method of saving it. But, when no treatment method helps, it is best to get the tooth removed as it could lead to complications in the future.
Need for tooth extractions
Cavities: In most cases, an extraction is performed when the patient has a bad cavity. We will try to restore the cavity-infected tooth using a tooth-colored filling material made from ceramic or composite resin. In the case of a bigger cavity, we would prefer an inlay. But, if the decay is so severe that there's no option but to remove the tooth, an extraction would be the last resort option.
External trauma: When the patient sustains an external injury to the mouth, it can result in cracking or chipped teeth. When left untreated, these teeth can give rise to infections or even fail. Restorations such as veneers, crowns, or composite bonding can be used to restore them. But when the tooth is too weak to be restored, it is best to extract it.
Root canal infection: Root canal infection is caused when the pulp of the tooth gets infected by the microbes in the oral cavity. Root canal therapy can be carried out to treat the condition. But, when it doesn't yield the desired results, the dentist would recommend you get the tooth extracted to keep the condition from spreading to the nearby teeth and gums as well.
Impacted wisdom tooth: Wisdom teeth may sometimes get impacted or, in simpler words, get stuck when they are emerging from the jawbone. This condition can be very painful and potentially give rise to infections. Extracting the impacted teeth is the best way to treat it.
