What to Expect: Getting a Crown on a Back Tooth
You're having a crown placed on an upper molar. The tooth currently has a large old silver (amalgam) filling, and over time a filling that big can leave the surrounding tooth walls thin and prone to fracturing. A crown is a custom cap that covers the entire tooth, protecting it and restoring full chewing strength. The goal is to prevent a bigger problem — like a cracked or split tooth — before it happens.
A good way to think about the appointment: the overall experience is a lot like getting a filling — the same sounds and sensations — just over a longer stretch of time. To keep you comfortable through that, we'll take frequent breaks so you can rest your jaw and pick up extra water as we go. Upper molars are generally straightforward to numb and easy to reach, and for a routine case like this we don't anticipate any discomfort or complications.
Here's how the appointment works, step by step.
Numbing. A topical gel is applied to the gum first, followed by local anesthetic to fully numb the tooth and surrounding area. We wait a few minutes and test the tooth before beginning, adding more anesthetic if needed. You shouldn't feel any pain during the procedure.
Initial scan. A digital scan of the tooth is taken before any work begins. This is a small handheld wand — no impression trays or putty — and it records your natural bite and tooth shape so the final crown fits the way you come together.
Removing the old filling. The existing amalgam is cleaned out. You'll notice water, vibration, and the sound of the handpiece, but no discomfort with the area numb.
Checking the tooth structure. With the filling removed, the underlying tooth is examined to confirm how much healthy structure remains and that the crown is the right plan.
Core buildup. Where the tooth was hollowed out by the old filling, a strong filling material is placed to rebuild the foundation. This gives the crown a solid base to sit on.
Preparing the tooth. The tooth is gently reshaped so the crown can fit over it like a tailored cap. The sensations are the same as before — water, vibration, light pressure, nothing sharp.
Final scan. A second digital scan captures the prepared tooth and is sent to the lab that fabricates the permanent crown.
Temporary crown. Because the lab needs about a week, a temporary crown is placed so you can eat and smile normally in the meantime. Chew a little more gently on that side and floss carefully around it. If it ever comes loose, it's not an emergency — just call the office and it can be recemented.
Delivery visit (about one week later). The temporary is removed and the permanent crown is tried in. The fit and bite are checked — you'll be asked to tap your teeth together so any high spots can be adjusted — and once everything feels right, the crown is permanently cemented. This visit is usually short. Because there's no drilling into the tooth at this appointment, you typically won't need to be numb — we can use a short-acting anesthetic if you'd prefer, or skip it altogether.
About the crown. Your permanent crown is made of zirconia, a tooth-colored ceramic that's very strong, making it well suited to back teeth that handle heavy chewing.
Throughout both visits, you're in control of the pace — if you ever want to pause, just let the team know and we'll stop. Nothing will happen without being explained to you first.
