Flossing the line

Okay, so, on a scale of 1 to 10, 1 being that I am totally overreacting and 10 being that this is entirely creepy and inappropriate, tell me how you think this rates:

I went to the dentist this morning for my 6-month cleaning and checkup. The appointment was at 9 AM, and I figured I would wait until after my teeth were cleaned to go re-stain them with my daily Starbucks. So by the time I sat down in the chair at 9:15 all I wanted to do was nap. No small talk, no polite chit chat, just let me recline, close my eyes, open my mouth and tell me when it's over.

The hygienist was a nice enough man who insisted on keeping me awake, peppering the hour-long cleaning with polite questions about my life, my job, my flossing habits. I gave him one word answers only when it was truly necessary to respond, and spent the hour in silent prayer wishing that he would just stop talking. At one point it occured to me that my closed-eye silence (read: ignorning) could be misconstrued as rude, but frankly, I was too tired to care. Much. By 10 AM I was out the door, teeth cleaned and cavity-free, thinking about the day ahead.

Two hours later my cell phone rings. It's the dental hygienist. It took me a minute to figure out who it was, because he announced himself by his first name, which I hadn't bothered to pick up when he introduced himself that morning. Once that awkwardness was out of the way, I decided he must be calling because I had left the office without the referral I had requested. But no. He was calling to see if I'd like to go for lunch sometime.

Um, what?

Aside from the fact that he's probably ten years older than me, has a child, and that I was ignoring him all morning, there's the slight ick factor which is that HE IS MY DENTAL HYGIENIST. It's not that he's a dental hygienist - I'm not discriminating against the profession; but isn't there some unwritten (and possibly written) code somewhere that specifies that it is in no way kosher to date your patients? Ever? Doesn't he watch Grey's Anatomy? Regardless, let's back up for a second...

I hadn't given him my number. At least, I hadn't given it to him for that purpose. The office obviously has it for contact information, but I certainly didn't expect it would be used for anything other than an appointment confirmation. So he pulled my cell phone number out of my private file. For what, exactly? Did he think my pre-coffee coma was really my way of playing hard to get? When I thanked him for the free toothbrush did he think I was picturing it at his place? Or does this happen to other people all the time and I should take my head out of my ass and get over myself?

I told him that because I work in Pasadena, I'm not usually in his neighborhood for lunch, but I took his number to call him in case I ever was. Not that I will. If this were a different situation, had I met him in a bar, per se, I would have blown this off and immediately forgotton about it. But now I may have to see him again in six months. And I'll have to trust him with sharp dental objects and also to not look up my shirt when I am negative 45 degrees in the reclining chair. The whole thing just makes me very uncomfortable.

What do you think? Am I overreacting or was he out of line? And can you recommend a new dentist on the west side?
