I've been using the standard 3% solution off the shelf for oral hygiene. It definitely cleans very thoroughly. Is it enough, though, instead of a diluted 35% solution? I'm also concerned with H2O2's effect on my fillings and enamel. Should I be worried about this? Thanks!!

If it's working for you, it's fine, but the thing about 35% food grade hydrogen peroxide is its versatility: you can dilute it to your exact specification for whatever use you want. With a 3% solution, you're stuck with a 3% (or less) concentration. And OTC 3% hydrogen peroxides are not safe for ingestion!
Our recommendation of 1:16 hydrogen peroxide to clean water yields a solution less than 3% concentration. That's still too strong to take internally, but it's plenty effective for oral health.
As far as your concerns, there's a study that shows even dentist-applied tooth whitening product with a whopping 38% hydrogen peroxide content doesn't affect enamel. Here's a link to an article about it: http://www.drbicuspid.com/index.aspx?sec=ser&sub=def&pag=dis&ItemID=304384
Thank you!
