What are dental X-rays used for?
Dental x-rays are extremely versatile diagnostic tools. Some of their main uses in dentistry include:
Assessing the amount of space available for incoming teeth.
Checking whether primary teeth are being shed in good time for adult teeth to emerge.
Evaluating the progression of bone disease.
Monitoring and diagnosing tooth decay.
Planning treatment (especially orthodontic treatment).
Revealing bone injuries, abscesses, and tumors.
Revealing impacted wisdom teeth.
When will my child need dental X-rays?
Individual circumstances dictate how often a child needs to have dental radiographs taken. Children at higher-than-average risk of childhood tooth decay (as determined by the dentist) may need biannual radiographs to monitor changes in the condition of the teeth. Likewise, children who are at high risk for orthodontic problems, for example, malocclusion, may also need sets of radiographs taken more frequently for monitoring purposes.
Children at average or below average risk for tooth decay and orthodontic problems should have a set of dental X-rays taken every one to two years. Even in cases where the dentist suspects no decay at all, it is still important to periodically monitor tooth and jaw growth – primarily to ensure there is sufficient space available for incoming permanent teeth.
If the oral region has been subject to trauma or injury, the dentist may want to X-ray the mouth immediately. Developments in X-ray technology mean that specific areas of the mouth can be targeted and X-rayed separately, reducing the amount of unnecessary X-ray exposure.
What precautions will be taken to ensure my child’s safety?
Though dental radiographs are perfectly safe for use on children, the dentist will take several precautions to ensure the X-ray process does not unduly damage the child’s cells and bodily tissues.
First, the child will be covered in a lead apron to protect the body from unnecessary exposure. Second, the dentist will use shields to protect the parts of the face that are not being X-rayed. Finally, the dentist will use high-speed film to reduce radiation exposure as much as possible.
If you have questions or concerns about dental radiographs or X-rays, please contact your dentist.
