Dental X-rays are an important part of the dental exam, used to diagnose problems with the teeth, gums and jaw.
X-rays use electromagnetic radiation to produce these images, they form wavelengths that penetrate the soft tissue of the body and are absorbed by denser materials, creating pictures of your bones or teeth.
And since your dentist doesn't have X-ray vision, they're necessary to distinguish dental problems not visible to the naked eye.
Tooth decay, periodontal disease, impacted teeth, bite problems and even tumors are just a few of the dental conditions easily found with dental X-rays.

Bitewings are a type of dental X-rays used to check the back teeth. As they show the crown of the tooth, bitewing X-rays are extremely helpful in determining tooth decay located in between teeth, various stages of gum disease and problems with tooth alignment.
Bitewings are also excellent for detecting a buildup of dental tartar, and are sometimes used to measure bone loss due to advanced periodontal disease.
