Have you ever thought about what happens when you have a filling? According to our resident dental health blogger Dr. Emma, “A filling is one of the most commonly performed dental procedures, but perhaps the most misunderstood. It seems simple, right? There's a hole in a tooth, fill it up with stuff. Well, this isn’t the case – teeth are tricky creatures, and the mouth is an incredibly hostile environment in which to get materials to stick and last. There's a lot that goes into preparing a tooth to be filled, as well as selecting the right material.” In this article, Dr. Emma helps us to understand by detailing her step-by-step procedure when completing a common filling.
