Let’s get the boring stuff out of the way so you can get back to scrolling on your phone while the baby naps. Most dentists will tell you to avoid professional in-office bleaching treatments with high-concentration hydrogen peroxide. Why? Because nobody has done the massive, expensive study on lactating women to say, "Yep, this is 100% fine." The peroxide can theoretically sneak into your bloodstream and then into your milk.
It’s like eating a ghost pepper salsa while you’re nursing: probably fine, but do you really want to test that theory? I didn’t think so. Stick with the gentle stuff and save the heavy artillery for when your kid is in college.
