What are the benefits of having the dental transillumination test?

Highlights defects: Dental transillumination test highlights the defects that are not easily seen inside the tooth.

Fracture ID: Dentists often use transillumination as a way to look for fractures inside teeth. It is a bright light that shines on the tooth and can make internal problems more evident. It is painless, and helps identify or confirm hidden problems.

Cracked teeth: Often it is extremely difficult to see if a tooth has cracked visually or on a dental radiograph (x-ray). By shinning light on a tooth, the dentist can detect breaks in the enamel matrix that are sharply contrasted due to the light not uniformly penetrating the area . Cracks can easily be detected. Cracked teeth can lead to dental pain and tooth loss if left untreated.
