Once we get the final crown back from the lab, then we arrive at the final appointment where we try in the permanent crown. When we slip on the crown over the remaining tooth, we check five criteria for an acceptable crown. We will also make necessary adjustments so the crown will pass all those checkpoints.
First, we check how well the adjacent teeth contact each other. If floss snaps through the crown and adjacent tooth nicely, it will also likely prevent food from getting trapped between the teeth when chewing. If the contact is open, the dentist must send the crown back to the lab to add material for adequate contact. If the connection is too tight, the crown won’t sit down all the way, and the dentist will adjust it until it touches adequately.
Second, we check the internal of the crown. If something is high or off internally, the crown will rock and loosen in time. Therefore, any high spot should be adjusted so that it is stable.
Third, we check the margin where the tooth and crown meet. The margin needs to be flush and not catch my explorer when I feel the margin. If the margin is open or overhanging, the lab will need to remake the crown because it will trap food, and decay will start here.
Fourth, we check the bite. Before making adjustments, the bite is commonly off when it comes back from the lab. The dentist will file down high spots until the tooth feels like it bites evenly. If biting down hits this tooth before other teeth, it can become sore over time and even cause jaw problems.
Fifth, we check the cosmetics. If the patient and I are happy with how it looks, it is ready to be cemented. Most of the time, the cosmetics are exceptional on the first visit. Therefore, we will typically achieve the desired cosmetic outcome for even our most particular patients. However, sometimes, it requires sending the crown back to the lab for improvements. Nevertheless, as you can see from our cosmetics gallery, we can arrive at very cosmetic results for every dental crown procedure.
