[|Human|] I have had a bottom retainer in my mouth for years. I have noticed that my teeth below my bottom retainer are turning grey there. I just got my bottom retainer removed today. I havent gone to the dentist in years. My orthodontist told me to see a doctor as soon as possible. I cant get in to see a doctor till march of next year. Why are bottom four front teeth where my bottom retainer was it. Why is it turning grey there?
[|AI|]  Hi, Thank you for consulting Chat Doctor. The grayish /reassured/blackish/bluish discoloration of teeth is due to the blood vessels supplying the tooth being necroses or stagnated, due to which the teeth loose its vitality and discolors. The color of the teeth changes due to the reduced blood components and their products. I Advise you to visit an oral physician who will evaluate the vitality of those discolored teeth, which were probably discolored by infection or undue pressure of the retainer. Take care.
