Doctor Who Imagine 1: Dentist

The fandoms I have so far: Doctor Who, The Phantom of the Opera, Sherlock, Markiplier, Jacksepticeye, and one for Fantastic Beasts and Where to Find Them. I hope to include many more in the story parts yet to come! :D Some may be terribly long though. I apologize. ^^;
They're mainly self-inserts, but I'll try to keep the perspective from (Y/N)'s point of view. I'm open for suggestions, just as long as I haven't done it already (like, ice cream for POTO. I've already done it, but I could do it for other fandoms!).
Updates are kind of like miracles; they happen whenever they happen. ^^;
