Clinically there is no such thing as a fire tooth, it may refer to a focal tooth, such as a tooth with recurrent painful infections. Depending on the specific cause, if the tooth is apical periodontitis, root removal requires root canal treatment. If it is periodontitis, then periodontal treatment is needed. Focal teeth, such as teeth with recurrent painful infections, require a detailed oral clinical examination and radiographs to identify the cause. If the tooth is apical periodontitis, root removal requires root canal therapy to remove severely diseased pulp tissue. If it is periodontitis, then periodontal treatment is needed to remove plaque, tartar, and soft tartar and reduce the depth of periodontal pockets. If the tooth cannot be retained, then direct extraction eliminates the lesion. Consultation with a medical professional is recommended.
