I had one bite-wing X-ray on both sides, one panoramic X-ray, and a few days later, another panoramic X-ray at the clinic because my wisdom teeth needed to be extracted. Will I be OK? Or was I exposed to too much radiation?

You will be ok, otherwise they wouldn't have done the X-rays

The radiation level and nature of the radiation is so low that it causes absolutely no damage.
You incur more radiation on an intercontinental flight
