Not every visit to the dentist requires X-rays, but at some point, your dentist will have a reason to include this step in your appointment. To help you feel informed and prepared, here’s a closer look at the answers to some common questions about dental X-rays.
How often do I need a dental X-ray?
The answer to this question can vary a little depending on the patient and their specific dental history and current situation. If you have an ongoing issue or are in the midst of a longer-term procedure, you may need more regular X-rays. However, if your teeth, gums, and jaw are generally considered to be healthy and no issues are detected by your dentist during regular examination, you will most likely be advised to have X-rays taken every couple of years. Children often require more frequent X-rays, as their teeth and jaws are still developing, and they are also often more susceptible to tooth decay.
If you’re a new patient, your dentist will likely want to take X-rays to make sure they are familiar with any issues and to establish a baseline. If you had X-rays recently at another clinic, you may be able to get these sent over instead of doing this again.
Why do I need a dental X-ray?
Routine dental X-rays are recommended for a number of reasons. For adults, an X-ray can:
- Show tooth decay that isn’t apparent during a regular visual examination – for example, areas of decay between teeth or under an existing dental filling. Approximately 35-40% of a tooth’s surface cannot be seen without an X-ray!
- Detect issues with your jaw, such as bone loss from gum disease.
- Reveal an abscess (infection).
There are some additional reasons for routine dental X-rays with children, such as:
- Checking on the development of permanent teeth and wisdom teeth.
- Determining whether there is sufficient room for tooth development, or if orthodontics should be considered.
Along with routine updates, a dental X-rays can be required if:
- You are preparing for a procedure like removal of a tooth, dental implants, crowns and bridges, braces, or others.
- You suffer from xerostomia, which can increase your rate of tooth decay.
- You are a smoker, which greatly increases risks of oral cancer, gum disease, and other oral health issues.
