Question about dental visit with new dentist?

Hello,

I had to switch dentists because of my work schedule. The new dentist offers evening appointments so I do not have to miss work to go. My old dentist forwarded my record to the new office and I called today to schedule my appointment. I know to expect a tooth cleaning and to fill out a health history, but will the dentist do anything with my retainers? My old dentist made me new ones at my last visit since the ones from the orthodontist were very loose. They used to clean them for me at every visit and check them to make sure they fit properly. If I bring them with me, will the new dentist do the same? Also, since I am a new patient, do I have to get x-rays even if I have had them within the past year? Finally, what else will the dentist check in the exam besides cavities?
