I am on Invisalign treatment and my teeth have turned brown. What to do?

Hi,

Welcome to icliniq.com.

I have seen the pictures you have attached along with the complaint (attachment removed to protect patient identity). These are nothing but stains and calculus. A layer of a chalk-like substance formed over the teeth surfaces especially on the back side of your lower teeth is the calculus. It is prone to get stained by various food substances and sometimes turn yellow to green. The brown colored areas which you are concerned about at the moment are just external stains and occur due to drinking coffee or tea regularly or even because of smoking. These are not because of the Invisalign treatment but occur commonly with anyone. The treatment is as simple as getting a professional cleaning done by your dentist. To maintain the clean teeth, you got to follow the oral hygiene instructions given by the dentist after then.
