One week ago I got two veneers on my front teeth. The right one looks nice, but the left one shows two white crossed lines. There are in those places where the grooves on the tooth were made. Plus this tooth does not feel quite right. It is sensitive when I floss it and if I squeeze it with fingers I feel sensitivity inside. The other tooth does not have those symptoms. I wonder if the left tooth did not bond to the tooth very well. Do I need to redo it?
