Bad breath after getting a crown

User Level:
Posted by: sk8trgirl  (8 years ago)
Hello there,

I've had a root canal and a crown on one of my back teeth. Two months after the procedure, I noticed bad breath. As days go by, the smell is becoming horrible that it is difficult to live with and it tastes like vomit. I have been brushing, flossing and rinsing with mouthwash every after meal but the smell remains. If I rub my finger in the gum area just above the crown, it smells really bad. Can someone please help and advise me on the action that I must take? I am really helpless. Thanks a lot!

It sounds like the seal may be leaking on the crown. Have it checked by your dentist. He can remove or redo the crown.

Go to the dentist and have an xray of the tooth. You might be suffering from an infection under the crown. The presence of bacteria causes the rancid smell you are describing.

What you have is a misaligned crown. If the bad smell came very soon after the crown was put on, that means it was not done right. A crown should last at least 10 years before it begins to deteriorate. What you have happening is that there is a small pocket or space between the crown and the tooth where bacteria is living. That's what smells bad. You need to press your dentist to redo the crown and to make sure it is done right. The crown has to cover the tooth without any gaps.
