Dental X-Rays
What are Dental X-Rays?
Reasons for taking X-Rays
- To look for decay in between teeth
- To check for the bone loss associated with gum disease
- To check for decay under older fillings
- To see if there are signs of infection at the very bottom of the tooth root
- To examine a problem area before it is treated with a procedure

Types of Dental X-rays
Bitewing X-rays
These show the upper and lower back teeth in one view. They are used to check for decay between teeth and to show how well the upper and lower teeth line up.
Periapical X-rays
These focus on two complete teeth from root to crown. They can find problems below the gums, like impacted teeth, abscesses, or cysts.
Panoramic X-rays
These give a broad view of the entire mouth area, showing all the teeth in both jaws on a single image. They can reveal tumors, cysts, jaw disorders, and impacted teeth.
Occlusal X-rays
These are larger and show full tooth development and placement. They can 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.
Orthodontic X-rays (Cephalometric Projections)
These show an entire side of the head. They help plan orthodontic treatment by looking at the teeth in relation to the jaw and profile of the individual.
Cone Beam Computed Tomography (CBCT)
This advanced technology produces 3D images of dental structures, soft tissues, nerve paths, and bone. It's often used for dental implant planning, complex extractions, and evaluating the jaws and face.
Digital X-rays
These are a more modern method where electronic sensors are used instead of traditional film. The images appear on a computer screen quickly and can be enlarged or enhanced for better viewing.
Dental X-Rays FAQs
X-ray frequency varies per dental office and patient; some need them yearly, others biannually or more often based on conditions. It hinges on your oral health and history. Prone to cavities? Annual x-rays might be needed. Cavity-free for five years? You might wait longer between x-rays.
- Make sure the mouth is large enough to accommodate incoming teeth
- Monitor the development of wisdom teeth
- Determine whether primary teeth are loosening properly to accommodate new permanent teeth
- Identify decay and gum disease early
Children’s need for dental x-rays differs individually. X-rays are taken based on medical/dental history and a clinical exam, only if they provide extra information beyond a visual check. Kids usually need x-rays more often than adults due to rapid growth and higher decay risk. High-risk children may need x-rays every six months, while those at low risk need them less often.
X-ray films detect more than cavities. They help assess erupting teeth, bone diseases, injuries, and orthodontic planning. Dentists rely on x-rays for conditions invisible to the naked eye, making early detection and treatment more comfortable and cost-effective.
Dentists and hygienists must probe and measure the gums around the implant as they would around teeth, examine and compare x-rays annually, assess for looseness, evaluate the bite, and inspect all components attached to the implants to ensure proper function.
