Baking soda or banana peels.
The old baking soda/peroxide once a week.
just whitening toothpaste
i didnt think any of that over the counter stuff really worked
I use a whitening night-time mouthwash. I just gargle with it right after brushing my teeth before bed.
I had some periodontal trays made for both my upper and lower teeth (They had to be made from a casting.), and I used peroxident (?)<br />
at night. The gel is expensive and really hard to find, but it REALLY works!
