I’m terribly scared of actually going to the test and have put it off for years… I noticed these brown spots on each of my molars, on the outside/side next to the cheek. They don’t hurt, but I can’t scrape them off. How bad is this? I’m going to the test for a cleaning soon and I don’t want to be caught horribly off guard with any bad news. Am I going to lose the tooth? I know they’re not great photos, I’m so sorry.
