Why Do Dentists Take X-Rays?

If you are going to a new dentist, or if you haven’t gotten a check up in awhile, your dentist will probably start the visit with getting x-rays of your teeth. X-rays are not something that is abnormal and there are many benefits of getting x-rays of your teeth.

X-rays give your dentist the ability to see an up close and personal view of your teeth but also your tooth’s roots, and gums. They can help your dentist rule out any tooth decay, catch any decay that is happening early, as well as see if there are any other dental problems you may have.

Most Common What X-rays Show:

  • Cavities. This is a clear indicator of why dentists use x-rays as cavities need to be taken care of right away.
  • Anything that could be going wrong with the tooth itself & the roots. X-rays can help give insight that isn’t visible to the eye and give clearer details to anything your dentists suspects.
  • You are able to check the bone around the tooth with a x-ray.
  • They help diagnose any periodontal disease that is starting. Catching diseases in your mouth early leads to faster recovery and you can also stop the disease from spreading to other teeth or other parts of the mouth.
  • For younger children who are still growing teeth – they can help see how the development is going and to see if any teeth will be having problems.

How often are x-rays needed?

Your dentist will determine with your history and your family history how often dental x-rays are needed. If this is your first time at the dentist, your dentist will need to do more x-rays to get a better understanding of your teeth and mouth. As you continue going to the dentist regularly, less x-rays are needed.
