Is it safe to mix hydrogen peroxide and fluoride in toothpaste?

Ask yourself...: Out of all the hundreds of toothpastes out there, have you ever found one that is mixed with hydrogen peroxide? There is maybe one or two. Research doesn't show an advantage of using it as a toothpaste. Consider sticking with an ada recommended product instead of mixing up something at home.

Why?: While there is nothing inherently wrong with this, why would you do that? The problem is not the fluoride, but the hydrogen peroxide. To much hydrogen peroxide is definately not good for you and it should never be swallowed. Use an ada recommended toothpaste instead.

No problem.: If you mean brush with Fluoride toothpaste and then rinse with a 50-50 solution of hydrogen peroxide afterward, this should not be a problem. If your intention is to mix the two together and then brush your teeth with it, the only problem will be that is is messy and no more effective than doing it the first way.
