If the dental implant fails, the implant may be loosened or even fallen off due to the failure of the bone bonding with the implant. The failure may be caused by the pressure in the early stage, but the implant can be implanted in the later stage. However, the failure does not have a great impact on the body, so the patient does not have to worry too much. It is advisable to choose a regular hospital for dental implantation to avoid bacterial infection during the implantation process, which may lead to other bad changes in the body.
