I have porcelain crowns for over 15 years on 7 of my front teeth due to an accident, unfortanely I need to change them. Since this is a process that is going to need alot of money and time, i still have some stains on them. I regularly brush my teeth twice at least 2 minutes and floss them daily at night, but doesn't seems to help. Yes I am a smoker (but started to reduce) and coffee lover. Would a peroxide type of toothpaste help me keep the stains at bay until i get my treatment done?
