I'd like to use a whitening mouth wash, but they are all mint flavored and I can't stand the taste of mint. Would it be safe/effective to add peroxide to my regular mouthwash? If so, what proportion should I use?

Dear Jo,

It would likely not be effective.  The peroxide you can buy in the brown bottle is usually 3%.  This is often not enough to whiten teeth.  And diluted by mouthwash, it would certainly not work.

Try mixing the same peroxide with baking soda.  This is an old formula that was used for gum disease therapy.  It may also help get your teeth white.

Also, not a mouthwash, but effective, are Crest White Strips.
