My orthodontist wont be back in office until end of week and i am desperate for answers to some questions. I started invisalign 4 days ago and am experencing pain, as expected. However, my gums are extremely itchy and gets so bad at times i i take trays out for a little. Gums do not look irritated or abnormal in any way. At bedtime, i apply mi paste to teeth and gums, spit excess saliva, then insert trays. Not sure if mi paste is irritating my gums and making itching worse because notice the itching is worse 30 mins after apply and have rinse mouth and trays. Is the itching normal when start invisalign treatment? Could the mi paste be a contributing factor? Will i experience this throughout entire treatment period or will it go away? If itching common when start treatment, how long until i can expect some relief?
