Dental radiographs, also known as dental X-rays, are images of your teeth and surrounding structures that help your dentist diagnose and treat dental problems. Dental radiographs use low levels of radiation to capture detailed images of your teeth, bones, and soft tissues.

There are different types of dental radiographs, including:

1. Bitewing X-rays: These X-rays show the upper and lower teeth in a single view. They are commonly used to detect decay between teeth and to evaluate the fit of fillings.

2. Periapical X-rays: These X-rays show the entire tooth, from the crown to the tip of the root, as well as the surrounding bone structure. They are used to detect dental problems such as abscesses, cysts, and impacted teeth.

3. Panoramic or OPG X-rays: These X-rays show a broad view of the entire mouth, including the teeth, jaws, sinuses, and nasal area. They are often used to evaluate wisdom teeth, detect jaw problems, and plan orthodontic treatment.

Dental radiographs are thought to be safe, with very low levels of radiation exposure, especially when taken digitally. Your dentist will take necessary precautions, such as using a lead apron, to minimize your exposure to radiation.

Regular dental radiographs are an important part of maintaining good oral health, as they can help your dentist detect dental problems that may not be visible during a routine dental exam. Your dentist will recommend the frequency of dental radiographs based on your individual needs and oral health history.
