Extracted teeth are considered medical waste in hospitals and need to be discarded. Because there is a high possibility of bacteria on the surface of the tooth, and there is some blood on the surface of the extracted tooth, it is not recommended for other people to touch it to avoid transmitting other diseases. The best way to get rid of the extracted tooth is, of course, to give it to the hospital. If the patient brings the tooth home, try to soak it in a disinfectant solution to sterilize and disinfect it thoroughly to avoid spreading the disease. Afterwards, it can be put in a small closed box as a souvenir, but this is not the best way to handle it. If there are cavities or calculus on the surface of the tooth, the situation of plaque accumulation will be more obvious, so it is recommended to put it in a more hidden position and not to let others touch it.
