Should Dental Crowns Touch

I got a dental crown on a left rear molar. I’m a little concerned that it isn’t touching the opposing tooth. Does that matter or am I making a mountain out of a molehill?

Dear Mike,

Chart of TMJ and Neuromuscular Dentistry

I’m glad you are checking on this. It matters very much that your dental crowns touch. In fact, it even matters how they touch, this is called occlusion and it is important for proper function of your bite and jaw. If your jaw is properly aligned all your teeth touch when you clench them together.

One way to test this is to place a thin strip of plastic, 0.05 mm thick and the width of a tooth, on your back teeth. You should be able to clench your teeth together and prevent the strip from being withdrawn.

When you have back teeth which don’t touch, they will eventually drift toward each other, but that doesn’t mean they will meet in the right place. A misaligned bite is one of the causes of TMJ Disorder. That is a lifetime of pain which can be avoided by your dentist properly placing your dental crown.

Have your dentist re-do this. If you have trouble getting him to agree, show him this post.
