Q:

What percent hydrogen peroxide should I use?

Can you clear something up for me?I've come across some conflicting information about the dosage amount for using hydrogen peroxide in a mouthwash. Some say to use 35-percent H2O2, but others say to use the 3-percent kind. Could you please let me know what the correct recommendation is?

A: 35-percent H2O2 can be very dangerous if people try to drink or ingest it. The kind of peroxide I recommend for use as a mouthwash and a rinse for fresh fruits, vegetables, and cuts of meat is the 3-percent variety that you can buy at any drug store or supermarket.

You can use it as your toothpaste as well. Just mix the peroxide with baking soda to form a paste, and rub it into your gums.
