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.
