If you’ve ever had a toothache, then you know the pain can be excruciating. In some cases, the pain you feel is caused by more than just your tooth. An abscess is an infection at the root of a tooth or between the root and the surrounding gum tissue. This infection can be quite serious—even life threatening—and, therefore, demands urgent care. If you or a loved one has a toothache, don’t play the waiting game. Contact an emergency dentist in Milpitas for immediate diagnosis and treatment.
