Male 29, i am scheduled for extraction of simple left upper wisdom tooth after two week. dentist want me to get panorama x ray. is it safe?

Yes: You should absolutely get an xray before getting your tooth extracted. This is very important for them to assess the tooth, bone, and surrounding anatomy. If concerned about radiation it is a very very small amount that will not have any significant adverse effects. Proper imaging is needed prior to any surgical procedure in the mouth.

Minimal risk: First, you have no choice but to get an x-ray. No dentist that i know will remove a tooth without first taking an x-ray. All x-rays have some risk, but the risk is minimal. There are risks to breathing air, eating, flying, living in your own home. Ask your dentist if he\she can take just a single x-ray of your tooth for less radiation. However, a panoramic x-ray might be a good idea anyway!
