1.Look for decay between teeth: 
Sometimes decay isn’t visible to the naked eye and exists in areas the dentist cannot see.

2.Check for bone and loss associated with gum disease: 
Gum disease can cause bone loss and an x-ray will show how advanced it is.

3.Check for decay under fillings:
Sometimes decay under fillings can occur and can only be seen with an x-ray

4.Look for infection at the tip of the root: 
Infections can appear at the very bottom of your teeth where the bone is, which needs to be confirmed using an x-ray.

5.Examine the area before procedures: 
Dentists need a full view of the teeth and bone before procedures such as braces, implants, and tooth removal.
