Embarrassing question for dentists?

I have not been to the dentist in a long time. Like over 10 years...I know. Gross. I went a lot as a child which has made me not want to go now, and now I'm embarrassed about what they'll say..blah blah blah I know you don't care😅

There's a special going on near me for an exam/cleaning/xrays I'm going to do. I know that I'll need more things done, which is what I'm worried about.

My main thing is I'd like them to be white...they're a bit yellow now😔 I know it's a bad picture, but if you can see, I have a few bigger spots on the top of my front teeth. Will a cleaning take care of that? Or is there another procedure? Sorry for making you look at this 🤢😭
