In preparation of teeth for crowns or bridges, local anesthetics (injections) are usually needed. As a result of the injection or use of anesthesia, at times there may be swelling, jaw muscle tenderness or even a resultant numbness of the tongue, lips, teeth, jaws and/or facial tissues that is usually temporary; in rare instances, such numbness may be permanent.
It is the patient’s responsibility to inform the doctor and seek attention from him/her should any undue or unexpected problems occur, or if the patient is dissatisfied. Also, all instructions must be diligently followed, including scheduling and attending all appointments.
