DENTAL X-RAYS
Dental x-rays are an important, preventive diagnostic tool used by dentists to detect damages which are otherwise not visible during a regular dental exam.
Dentist and dental hygienists use this tool to accurately detect dental abnormalities or damages and provide the appropriate treatment plan for the patient. Without x-rays many problem areas may go undetected.
Some conditions detected by x-rays
- Abscesses or cysts
- Bone loss
- Cancerous and non-cancerous tumors
- Decay in between teeth
- Developmental abnormalities
- Poor tooth and root positions
- Problems within a tooth or below the gum line
Early detection of these dental problems can help you save your teeth before any permanent damage is done, avoid any unnecessary discomfort, save money and time.
Are dental x-rays safe?
Since they only produce a low level of radiation, dental x-rays are considered safe. The amount of exposure to radiation from a full mouth x-ray series is equal to the amount of radiation a single man is exposed to from his surroundings. However, the technician will take the necessary precautions to further limit the patient’s exposure to radiation while obtaining the x-ray by using a lead apron which will protect the body from being exposed, and by using modern fast developing films which will cut down the exposure time of the x-rays.
How often should x-rays be taken?
This would depend on each individual’s dental health needs. Your dentist or dental hygienist will recommend the requirement based on a thorough review of your medical and dental history, a dental exam, symptoms and signs, age of the patient and risk of disease.
Generally, a full mouth series of x-rays are recommended for new patients as it is valid for 3 to 5 years. A bite-wing x-ray (x-rays showing the upper and lower teeth line up) is recommended twice a year as part of a regular dental check-up. These type of x-rays can detect new dental problems such as tooth decay in between teeth.
