Welcome Bobby. First of all, congratulations on giving up all tobacco products! I am not a doctor or nurse, but raised a similar concern to my ENT at my 16 mo visit last week. His take was to keep an eye on it and let him know if it hasn't gone away in two weeks. Has the white spot remained in the same place the entire time and this is a change in it? Then I would call my ENT.

Sincerely,
Lisa in Ks
