I've never had a cavity but at my once o'half decade dental check-up the dentist found a tiny cavity on one of my back teeth. I'm completely housebound and mostly bedbound. Fairly sensory sensitive. Mostly just all around fragile. So, is there anything I need to consider when getting this cavity filled? What besides, drilling, do they do? What sort of chemicals do they give you? I've been avoiding it since that appointment last November -- initially because of my annual post-Christmas crash, but now because I'm afraid of what it might do to me and dreading a bad crash. In the meantime, I've been making sure to brush, floss, rinse with flouride-based mouthwash, chew xylitol mints in-between brushing, etc. I know it's not going to get any better but so far it hasn't gotten too much worse. But that won't last forever. Sigh.
