Is a peroxide mouthwash for porcelain veneers a good idea?

DR. HALL,
IS THIS OK? I MADE MY OWN MOUTH WASH: 8 OZ FILTERED AND BOILED WATER, 8 OZ OF 3% HYDROGEN PEROXIDE, 2 TBS SEA SALT.
I HAVE PORCELAIN VEENERS ON MY TEETH.
THANK YOU IN ADVANCE…….

Lorece,
Well, at least you aren’t using a mouthwash with alcohol. That would soften the bonding agent used to bond the porcelain veneers which will cause ditching and staining around the edges.

But the mouthwash you are mixing up at home will cause other problems. The active ingredient in the formula you gave me is the hydrogen peroxide. Hydrogen peroxide will kill a number of micro-organisms. Many of the bacteria that contribute to gum disease are what we call anaerobic—they thrive without the presence of oxygen and, in fact, oxygen will kill them. Hydrogen peroxide, when you rinse with it, bubbles and releases oxygen, killing these harmful bacteria. However, the peroxide will also kill many beneficial microbes that live in your mouth, which causes other oral micro-organisms to thrive because of the absence of competition. One of these micro-organisms is the yeast, candida albicans.

The result of all this is that occasional or short-term use of hydrogen peroxide as a mouthwash can be very helpful. But if you use it steadily for a period of, say, two weeks, you will end up with an oral yeast infection because the candida albicans will grow without restraint. In an oral yeast infection, the mucosal surfaces in your mouth turn white and peel, leaving raw, red, and painful patches.

There are a number of alcohol-free mouthwashes that you could use to help you care for your porcelain veneers, if you want to use a mouthwash. Check the link for more information about that. But my advice is that if you brush and floss faithfully and correctly, any need for a mouthwash would be minimal at best.
