Teeth are not bones, but like bones they are hard, mineralized tissues of the body. Generally speaking, the composition of teeth and bones are not the same, teeth mainly contain enamel, dentin, pulp, etc., while bones mainly include cortical bone, cancellous bone and bone marrow cavity. The main components of teeth and bones are mineralized components. Teeth mainly contain enamel, dentin, dentin, apatite crystals composed of calcium and phosphorus ions, and other phosphate crystals, etc., while bones are rich in calcium and phosphorus ions and calcium phosphate, etc. Therefore, these two are similar in terms of composition, while the teeth grow in the jawbone, although there is a commonality, the location is close, and through certain components linked together, cross-linked, but not replace each other, the bone can be repaired on its own after the occurrence of rupture, while the teeth can not be repaired on its own after damage, so these two are still different. It is recommended that patients should pay more attention to their own health, if there are oral problems, you need to cooperate with the doctor for examination and treatment.
