My tongue is being irritated by my crown?

Thank you for your inquiry. You should absolutely start by going back to your dentist who recently placed your crown. He/she will make sure your occlusion is ideal since mal-occluded bites may possibly lead to tooth fracture, discomfort/sensitivity, etc. This should be a simple fix to correct your occlusion - just be sure to explain to your dentist exactly how you feel so it can be corrected sooner rather than later.  You can also point out to your dentist where your tongue is being irritated so that area can be smoothed/polished out, a simple fix.  Your tongue will then need time to heal and get use to the new crown in place.  We hope this helps and wish you all the best!

You can go back to your dentist and have the sharp edge smoothened and polished. This is an easy and quick fix. 

Sometimes people say it's rough when they mean it's "bumpy". it may be anatomy of the tooth your feeling. If it's truly rough go back to the dentist and have him re-polish. Porcelain polishers should make the surface smooth as glass.
