So let’s look at this situation a little closer. You can see where the crown meets the tooth because there has been some recession of the gum tissue over the many years this crown has been in service. Also, this same area is starting to ‘leak’, that is, bacteria is migrating under the crown and infecting the tooth underneath. The tooth in front of the crown has a large cavity. In fact it’s big enough that you can see the gray ’shadow’ of the decay if you look closely. It was definitely time to fix these teeth.
