Black deposit on my teeth because of Abx?
I am just coming back from my dental hygienist because I really had to remove this thick black deposit on my teeth that started to appear several months ago (and after more than 6 months on my CPn Abx protocol). The hygienist was quite surprised by such a strong deposit, and she said the only cause she could think about is the Abx. Apparently some of them can cause such issues on teeth. I am taking Doxy (or Tetra) + Azithro + NAC on a daily basis, and Amoxi + Metro when pulsing. Anybody here already experienced the same issue on CAP?
