There is the possibility of an implant failing for various reasons — if an infection develops, which is rare, or if the bite (the way the teeth come together) has not been adequately adjusted. In addition, clenching or grinding teeth can put a lot of pressure on the implant. This may cause bone loss and cause the implant to break or fail. Poor oral hygiene and lack of regular preventive professional care can also contribute to implant failure.
When implants are used to replace lower teeth, there is the risk that a nerve in the jawbone could be injured, causing numbness or tingling. It can be temporary until the nerve heals, or it can be permanent. However, x-rays and CT scans help your dentist see where the nerve is located and minimize the possibility of injury. There is also the risk of sinus problems if a dental implant placed in the upper jaw protrudes into one of your sinus cavities. However, these risks are uncommon.
Implants may not be the easiest procedure, but they take time to be healthy and secure. Once you have your new implant and crown, make sure to take care of it — and every other part of your mouth, too! If you have questions about a dental implant procedure — for example, how long does a dental implant procedure take? — be sure to reach out to your dentist.
