How Long Has It Been Since Your Last Dental Visit? Signs You Need an Evaluation
August 26, 2026
When patients visit the dentist, they often assume that a visual examination is enough to determine the condition of their teeth. However, some dental conditions cannot be fully identified through a clinical examination alone.
Dental X-rays are diagnostic tools that allow dentists to examine structures that cannot be seen directly and obtain additional information needed to plan certain treatments.
Why might you need a dental X-ray?
An X-ray provides images of the internal structures of the teeth and the bone that supports them.
Depending on the situation, it can help identify cavities that cannot be seen during a visual examination, root abnormalities, bone loss, impacted teeth, infections, and other conditions that may need to be evaluated before treatment begins.
Not every patient needs the same type of X-ray. The appropriate imaging study depends on the clinical evaluation and the treatment being considered.
Which treatments may require dental imaging?
X-rays can be particularly useful before certain procedures, including root canal treatment, extractions, dental implants, orthodontic treatment, and some restorative procedures.
For dental implants, for example, the dentist may need to evaluate the amount and condition of the available bone to properly plan implant placement.
Dental panoramic X-ray: a broader view
A panoramic X-ray provides a broad image of the teeth, jaws, and other structures in the oral region.
It can be used as part of an initial evaluation and provide valuable information for planning different types of dental treatment.
However, it does not necessarily replace other imaging studies. Depending on the patient’s needs, additional imaging may be recommended.
What is a 3D dental scan?
For certain treatments, particularly when a more detailed evaluation of the bone and surrounding structures is needed, a cone beam computed tomography scan, commonly known as CBCT, may be recommended.
This type of imaging provides three-dimensional information that allows dental professionals to evaluate specific structures from different perspectives.
The decision to perform a CBCT scan depends on the clinical situation and the information needed for treatment planning.
Do you need X-rays at every dental visit?
Not necessarily.
The need for dental imaging depends on the patient’s condition, symptoms, dental history, and the treatment being considered.
The dentist should determine when an X-ray or other imaging study is necessary for diagnosis or treatment planning.
Why is this part of the evaluation important?
Starting treatment without the necessary diagnostic information can make treatment planning more difficult and may increase the risk of overlooking conditions that are not visible during a basic examination.
A comprehensive evaluation allows the dental team to make informed decisions and tailor treatment to each patient’s needs.
