Is the science behind modern night guards real? I had braces 4 years ago and I’ve been trying to get a new night guard for weeks now. The ones from the dentists are hundreds of dollars, even over a thousand, at times. But the putty molds you can get from a custom lab for under 200 dollars are incredibly hard to get “perfectly right”, which they require to make the mold. I’m worried about my teeth shifting because they’ve always told me that is what will happen if I don’t wear my night guard. But is this just more false modern science? What was the purpose of braces in the first place, if my teeth will just go back to how they were without extra post-braces retainers or night guards?
