So normally when you come to a filling appointment, the first thing that they're most likely going to do is give you a little bit of local anaesthetic just so you don't feel anything. Once that's in, they use a drill to clear out any decay that there is. And then once that has been done and they're happy with how it's looking, we'll then fill it up. Normally this is done with a material called composite. Once this is built up, they'll polish anything off, check you're biting okay and then go through any postoperative instructions with you.
