The proceedure wasn't that bad, they didn't have to numb me because it was just a tiny service level cavity. It wasn't too bad, kind of odd hearing a drill in my mouth and watching little pieces of something come flying out.
So after all it said and done I have this weird rough spot on my tooth. As I'm walking out they wanted to charge me $100! She said I had a $100 deductible. So I asked her about the money I paid last time, and why didn't that go towards this deductible. She looked it up, and sure enough it should have gone towards it. So instead she only charged me $54. She even complimented me on knowing my insurance policy because most people don't have a clue.
So I saved myself like $50 today just because I knew what my insurance covers, sweet! :)
Update: She just called me and told me that I was wrong. I have a $50 deductible since I'm single. Woohoo! So she cancelled the charge on my card all together.
