Just had 2 tooth x-rays and earlier this year a couple of foot x-rays for a fractured metatarsal. am i at too much x-ray exposure?

I wouldn't worry: First, taking 2 dental x-rays is almost insignificant in the total scheme of things. The x-rays to determine whether or not you had a fracture were necessary and one of the smaller radiation dosage producing types of images. Honestly, it's best if we never had to take x-rays but they are a necessary part of our lives. Do they have risks? Yes. We have risks all around us in the air, water, food etc.

No: No, those are minimal exposure localized x-rays with short burst cycles. You are more exposed to radiation from an overseas airplane voyage. You have not had too much x-ray exposure.

No: Both of these types of x-rays have extremely low dose radiation and in a lot of states the tech taking the xray does not need to wear a radiation badge anymore. You are safe. Without reason to be concerned.
