While a thorough visual inspection of the mouth will detect large and obvious holes, x-rays can show decay between teeth and changes in the thickness of bone caused by gum disease. They assist in determining any wear or breakdown of dental fillings. They can also reveal any unusual changes in the root and surrounding bone structures.
Detecting bacteria and decay that can be eating away the tooth unnoticed, is an important step in avoiding dental issues and complications. X-rays enable us to check hidden areas we can’t see with the naked eye.
