There are several types of dental X-rays, each serving a specific purpose:
-
Bitewing X-rays: These X-rays show the upper and lower back teeth and are used to detect decay between the teeth, as well as changes in bone density caused by gum disease.
-
Periapical X-rays: These X-rays focus on one or two specific teeth and show the entire tooth from the crown to the root, as well as the surrounding bone structure. They are used to detect problems such as tooth decay, infections, or bone loss.
-
Panoramic X-rays: Also known as panoramic radiographs, these X-rays capture a broad view of the entire mouth, including all the teeth, jaws, and surrounding structures. They are useful for assessing the overall oral health, detecting impacted teeth, evaluating the jaw joint (temporomandibular joint), and planning orthodontic treatment or dental implants.
-
Occlusal X-rays: These X-rays provide a detailed view of the floor of the mouth and are used to detect issues such as cysts, infections, or developmental abnormalities.
Dental X-rays are safe and emit very low levels of radiation. They are typically taken as part of a routine dental examination or when a specific dental problem is suspected. The frequency of X-rays depends on the individual's oral health status, age, and risk factors for dental disease. Your dentist will determine the appropriate type and frequency of X-rays based on your specific needs and concerns.
