How do you do your teeth whitening with 10% bleach (mine are from the dentist so had individual trays made). Asking as there seems to be quite a varied approach..my sister keeps her trays in overnight, but gets lots of sensitivity. My own dentist advised popping them in for an hour at a time & building the time up.
I tried the 16% bleach & got some zinging sensitivity, so swapped back to 10% & I've been very gradually using it over the last week for up to 2 hours with no issues. But no massive results either. Maybe to get a noticeable effect I'll have to bite the bullet & either go back to 16% or wear the trays for a few more hours at a time...
How do you do it & do you notice any side effects? Do you have to cut back on tea/coffee/red wine to keep them white?
