Do You Need a Crown on a Cracked Tooth?
We recently had a new patient see us with no tooth complaints, she just needed a check up and wanted to discuss her headaches to see if we could help. During her exam, I noticed that several of her molars were severely worn down (which she already knew about) and had cracks visible. We didn’t take photos at her appointment (should have!) to show her, but she seemed comfortable with my recommendation of doing crowns on those 4 teeth to catch and contain the cracks before the teeth break. Since she decided on a second opinion for those teeth, which I fully respect, I decided this is a good opportunity to review cracks in teeth, and what (if anything) to do about them. Tooth Cracks Don’t Show Up on X-Rays One difficulty with diagnosing cracks in teeth, is that they almost never show up on x-rays. Why, you ask? Good question! It’s because x-rays are traveling perpendicular to the cracks, and the cracks are so narrow, there’s not enough change in the tooth density for the x-rays to show it. To show up on an x-ray, a crack in a tooth would have to be so wide, you could stick a fork in it, and then you’d already know there was a problem. The x-ray shown here is from another patient we recently treated, and while you can’t see anything on the x-ray, want until you see how it looked inside the tooth (on below). […]
