I have porcelain veneers that I love. I’m mixing up a homemade mouthwash to help care for them, but wanted to run the ingredients by you first:
8 oz. Boiled water (I also filter my water)
8 oz. Hydrogen Peroxide
1 T. Sea Salt
Do you see anything harmful about this?
I am glad that you love your porcelain veneers and want to take good care of them. While nothing in the DIY mouthwash you listed will harm the porcelain veneers directly, there will be a separate issue.
Hydrogen peroxide releases oxygen. This will kill bad bacteria that leads to gum disease, but it will also kill good bacteria that helps your mouth. If you use this regularly, it will lead to candida growth and an oral yeast infection. Using a peroxide rinse every once in a while is fine, though.
In most cases, you don’t need a mouthwash to take care of your porcelain veneers. Regular brushing and flossing should do it. If you want a special toothpaste to help keep them white, then I would recommend Supersmile Toothpaste. This is specially designed for cosmetic dental work.
Some patients, however, really feel they need a mouthwash. If you are in that category, the most important thing is making sure that there is NO alcohol in the ingredients.
If there is, the alcohol will soften the bonding and cause ditching and staining around the edges. Using an alcohol-free mouthwash will prevent that.
