Fooled

So I have never have had a big filling in my life. Most of them have been tiny occlusal fillings on my back molars. Well there was one tooth that looked it could use a sealant. I wanted to be extra safe so I told the dentist to do a little bit more than a sealant and to just do a small filling so there won't be a big chance of it getting a big cavity. So I set up my room for a filling, put in my new favorite movie and sat in the chair. I didn't think it was going to be a big deal so I didn't get a shot. Well the dentist starts drilling and I am doing great. Can't feel a thing. A couple of minutes later he stops and asks if I can feel anything. I tell him no and he looks kinda shocked. He keeps "drilling" (that is in quotations for a reason...) and then stops again to ask me if I can feel anything. I thought he would be done with the filling by now...it should've been very small. He then tells me that it was a lot deeper than we thought it was and that we might need to get the endo stuff out. Endo stuff = root canal!!! WHAT?!? I'm too young to get a root canal! How could've it gotten that deep in only a matter of days since last we checked?!? I am a more than avid flosser and brusher! Well I kinda go out of it for a little bit because I am on the gas. But after the procedure was done I asked him if it was really that deep? I'm freaking out. Those of you who know me know why I am freaking out right about now. He looks at me and starts laughing.
Dentist: "I had the filling done within the first 5 minutes. The rest of the time I was pretending to drill so you would think that it was bigger!"
Me: ".....what?!"
Dentist: (chuckle)
Me: "So I don't need a root canal right?"
Dentist: "Heather that filling was tiny. You are fine."
What the heck! It's not April fools day yet! And of course they knew I would fall for it because I am the most gullible person they know! Shh don't tell anyone else.
