Sometimes after receiving a routine dental injection there is immediate swelling. This swelling along with "soreness" or " stiffness" on jaw opening, and bruising is called an injection hematoma. It may persist for several days following the procedure. Injection hematoma can happen any time an injection is given. It is due to the status of the local vascularity at the time of injection. The vascular bed does not immediately clot off after the injection is withdrawn causing a leakage of blood into/ between tissue spaces. These pooling of blood causes, noticeable swelling, muscle distention and trismus, and bruising 2-3 three days after It is not a reflection of poor technique, type of anesthetic used, or indication it will happen again. Patients that are on anticoagulant medications such as: aspirin, coumadin, ibuprofen, and others are at a greater list. Treatment consists of; immediately notify your dentist, sometimes antibiotics, cold compress, jaw exercise, and something for the pain (Tylenol)
