Hi i am a 28 years old lady. I just had my root canal therapy last May 2010 without a crown. It was my third tooth from the right starting from the back. Because of the guava i ate and the years my root canal have been made my tooth crack. Now the doctor told me that i have only two solutions for this. Either porcelain or plastic crown. I am kind of hesitant to get both solution cos my tooth is no longer strong and it cost a lot too. So im planning on extraction. Is a good choice though?
