“I have only been using the strips for 1 week now (for 1 hour each time as my teeth are very stained), and I am starting to notice a difference, however the small white parts I am noticing are patchy and uneven, and don’t cover the whole surface area of the teeth so far (even though the strip is pressed against the full surface area). I am interested to see what the end of 2 weeks will be like”
