When i was kid i have a gap in my front teeth. i didn't have a problem with it, but my parents forced me to wear braces. Unfortunately, when the dentist removed the braces, he cleaned the glue-like substance remnant on my teeth. He drilled it too much, causing my teeth become yellowish. I'm very sad, because before wore braces, my teeth are normal except the gap. And after braces removal the dentist made me have 4 crowns on my upper incisors and yellow canines. The left yellow canine is too different. Many people ask about it and it's irritating me. I don't want to have my teeth being crowned again. Is there any drug or food to help me grow my enamel back to normal?View Thread
