I had a total of 22 veneers and crowns fitted almost 3 weeks ago. I'm a redhead with a real sensitivity in my teeth but I did not realise that there would be sensitivity that would last this long. I'm very sensitive to hot and cold and am on painkillers each day. If this is normal for someone like me, who is sensitive, I can wait for it to settle down but am not sure how long this could take.
