Are All These X-Rays My Dentist Gives Me Necessary?

The short answer is no – you do not need a full range of x-rays for every dental issue you encounter.

 

Often, dentists will order multiple x-rays in order to thoroughly examine the mouth and oral structures. There are times when dentists overdo it though – usually with new patients – and order multiple x-rays which aren’t actually necessary as part of their protocol. The radiation produced by x-rays are minimal, but every effort should be made to reduce exposure and minimize the use of x-ray machines.

 

For this reason, each consultation needs to be personalised and x-rays should only be ordered when necessary. Your dentist should first thoroughly examine the mouth and oral structures to determine whether there are problem areas before ordering x-rays to further examine these trouble areas.

 

A full-mouth series of x-rays should be reserved for patients who have had extensive dental procedures performed or have excessive active decay, and patients who have a higher risk of decay should only have x-rays ordered every 6 – 18 months. A patient who is not at high risk should only have x-rays done every 2 – 3 years and children, who are more sensitive to radiation, should hardly ever have x-rays done.

 

There are various types of dental X-rays, including:

 

  • Bitewing X-rays, which reveal cavities between teeth. They are called bitewings because you bite down on a wing-shaped device to hold the X-ray film in place.

 

  • Panoramic X-rays, which require a special machine that rotates around the head to provide a detailed image of all the teeth and the underlying bones in a single X-ray.

 

  • Periapical X-rays, which capture images of two or three teeth at a time. They can reveal an abscess caused by an infection or root caries, which are lesions at the base of the tooth. Film is placed on a holder, then put vertically in the mouth to take the x-ray.

 

  • Dental cone-beam CT (CBCT) scans, which provide 3-D X-ray images of the teeth, their roots and the jaw.

 

If you have concerns about the number of x-rays your dentist has ordered, ask them to explain the purpose of each one. If your dentist tells you that it’s their protocol or policy to order multiple x-rays, you can decline the x-rays and request that only the absolute necessary x-rays be performed.
