X-Rays and Partial Plate Questions

Q. I visit my dentist twice a year and once each year he takes x-rays. He brags that his x-ray machine is from 1962 (still has tubes and needs to warm up) and still works.

Should I be concerned about radioactivity from such an old machine? Do newer x-ray machines show more information that he may be missing? Thank you.

A. X-ray machines are inspected to be sure that they meet the appropriate standards. You can ask your dentist about that.

Most modern x-ray equipment does not have to "warm up", and in combination with x-ray film that requires minimal exposure time produces great images with minimal exposure to the radiation.

Additionally, digital x-rays are efficient, low radiation dose equipment.

Q. I am 71 and need to replace a fixed type bridge in order to have dental work done to two of four remaining molars.

My question is would it be best to have a partial removable plate made in the event other molars need work done in the future and also is it possible to add additional dentures to this new partial?

A. It is possible to add teeth to partial dentures in the future. It does depend on how the partial denture is designed, although.

Your dentist has likely recommended what he/she feels is in the best interest of your oral health. I am sure that he has evaluated how sound (gum health and risk of future cavities) your remaining teeth are.

Natural teeth function more efficiently than partial denture teeth.
