My two front bottom teeth grew in discolored when I was younger, so they have been bonded since childhood. Recently, I got dental crowns on them. I have OCD and was adamant about getting the whitest shade possible that still looked natural. I whitened my teeth before getting the crowns, as well. My dentist was wonderfully helpful. However, I feel I may have taken it too far with the shade because they appear too white compared to the others despite continued whitening of my naturals. Any advice?
