Most dental insurance plans cover X-rays, but the frequency of coverage varies depending on the type of X-ray and the reason for the procedure.
Typically, dental insurance covers routine X-rays every 12 to 24 months, depending on the individual's oral health needs.
However, some insurance plans may cover more frequent X-rays for patients with a history of oral health issues or those who are at high risk for developing certain conditions.
For example, patients with a history of tooth decay or gum disease may be eligible for more frequent X-rays to monitor their condition.

Types of X-Rays
Dental X-rays come in several types, each with its own unique purpose.
Intraoral X-rays, which are taken inside the mouth, are the most common type. They're used to detect problems between teeth and below the gum line.
Bitewing X-rays, a type of intraoral X-ray, are particularly useful for spotting cavities and signs of gum disease.
Panoramic X-rays, which capture a wide view of the mouth, are often used to evaluate the alignment of teeth and the presence of any abnormalities in the jawbone.

Bitewing X-Rays
Bitewing X-rays are taken during routine dental check-ups to check for cavities between teeth. Most insurance plans cover bitewing X-rays once or twice a year.
These X-rays show cavities in between your teeth and changes in bone level, which may be impacted by gum disease. They usually consist of two or four images that allow the dentist to view all the teeth located in the back of the mouth.
Bitewing X-rays are typically taken at a routine checkup appointment.

Occlusal X-rays capture the roof or floor of the mouth and are used to find extra teeth, teeth that have not yet broken through the gums, jaw fractures, a cleft in the roof of the mouth, cysts, abscesses, or growths.
Coverage for occlusal X-rays depends on the plan and the clinical need.
Cephalometric
Cephalometric X-rays are often used in orthodontics to show an entire side of the head.
Their coverage will vary based on the insurance policy and the specific need for the X-ray, especially if it's related to orthodontic treatment planning.
It's crucial to understand that insurance coverage for X-rays can be unpredictable, even with general frequencies.
Some insurance policies might have limitations or waiting periods, while others may be more flexible if the dentist provides justification for the need.
