Extraction of the wrong tooth: Misdiagnosis, altered tooth morphology, faulty clinical examination, poor patient history, undetected/unmentioned previous extractions that may predispose the operator to consider another tooth to be a replicate of the one previously extracted are a few causes of extraction of a wrong tooth.
Overerupted teeth are often sharp due to lack of tooth wear (dental attrition) by adjacent teeth during chewing. [citation needed] Overeruption is treated either by forcing the tooth back using orthodontic techniques, or by cutting the interfering part of the tooth and installing a crown. [citation needed]
Instruments may separate (break) during root canal treatment, meaning a portion of the metal file used during the procedure remains inside the tooth. The file segment may be left behind if an acceptable level of cleaning and shaping has already been completed and attempting to remove the segment would risk damage to the tooth.
A tooth with extensive caries eventually requiring extraction. In certain cases, endodontic therapy may be necessary for the restoration of a tooth. [143] Endodontic therapy, also known as a "root canal", is recommended if the pulp in a tooth dies from infection by decay-causing bacteria or from trauma.
Alveolar bone resorption is a common side effect of tooth removal (extraction) due to severe tooth decay, trauma, or infection that limits dental implant placement. Surgical bone augmentation is associated with limitations such as high cost, bone graft rejection or failure, pain, infection, and the addition of 6–12 months to the treatment ...
All teeth are classified as either developing, erupted (into the mouth), embedded (failure to erupt despite lack of blockage from another tooth), or impacted. Impacted teeth are ones that fail to erupt due to blockage from other teeth. Wisdom teeth, as the last teeth to erupt in the mouth are the most likely to become impacted.
Thus, tooth extraction may be a reasonable treatment option. The tooth could then be replaced with a dental implant. Alternatively, orthodontic extrusion can be used to achieve crown lengthening. Using brackets, light forces can be used to pull the tooth away from the gums within a few months.
Tooth hemisection is a type of endodontic surgery in which a root and its overlying portion of the crown are separated from the rest of the tooth; the separated part may be optionally removed. It contrasts with root resection , where a root is removed while leaving the crown intact, and an apicoectomy , where only the tip of the root is removed.
