Digital radiography (digital X-ray) is the latest technology used to take dental X-rays. This technique uses an electronic sensor that captures and stores the digital image on a computer. This image can be instantly viewed and enlarged, helping the dentist and dental hygienist detect problems more easily. Digital X-rays reduce radiation 80-90% compared to the already low exposure of traditional dental X-rays.
Dental X-rays are essential, preventative, diagnostic tools that provide valuable information not visible during a regular dental exam. Dentists and dental hygienists use this information to safely and accurately detect hidden dental abnormalities and complete an accurate treatment plan. Without X-rays, problem areas can go undetected.
Dental X-rays can reveal:
- Abscesses or cysts.
- Bone loss.
- Cancerous and non-cancerous tumors.
- Decay between the teeth.
- Developmental abnormalities.
- Poor tooth and root positions.
- Problems inside a tooth or below the gum line.
How often should dental X-rays be taken?
The need for dental X-rays depends on each patient’s individual dental health needs. Your dentist and dental hygienist will recommend necessary X-rays based upon the review of your medical and dental history, a dental exam, signs and symptoms, your age, and risk of disease.
A full mouth series of dental X-rays is recommended for new patients. A full series is usually good for three years. Bite-wing X-rays (X-rays of top and bottom teeth biting together) are taken at recall (check-up) visits and are recommended once or twice a year to detect new dental problems.
