So just over a month ago I had a checkup and a clean and I had 3 cavitys which are all fixed. I've been doing Invisalign for 2 weeks now so I'm constantly bushing my teeth and flossing 3 times a day and I noticed this orange spot in the crease of my back teeth (not sure if old or new). I'm freaking out because I just spent $1000 on cavitys a month ago and now this! It's not painful or anything at all and I'm hoping not decay. What does it look like to you?
