Pregnant dentists, how do you avoid Xrays?

Hi po! I recently found out I'm 3-4 weeks pregnant. I'm just wondering for any tips on how to avoid radiation.

🔸️I use my fingers to position the sensor (I know, very bad) but my patients hate my positioner and it usually don't give me the results I need 🔸️My assistant is still new. I'm looking to train her pero it's only me and her at the clinic so it will be tricky to do on her own without a positioner 🔸️ We're using a size 1 sensor. I can honestly upgrade to a size 2 but trying to see if there are ways around this first.

Any thoughts? Most esp sa mga dentists na nanganak na?
