How is an abscessed tooth diagnosed?
In addition to examining the tooth and surrounding tissue for signs of infection, your dentist may:
- Recommend an X-ray. This can help identify sources of dental disease that may have led to the infection. Your dentist can also use X-rays to determine if the infection has spread and may be affecting other areas.
- Recommend a CT scan. If the infection has spread to other areas within the neck, this will help to identify the extent of the infection.
- Tap and press on your teeth. A tooth with an abscess is often sensitive to touch or pressure.
- Thermal tests. These tests will help your dentist determine the health of your pulpal tissues.
