There are a lot of reasons why you shouldn’t smoke, but one of them is that nicotine and tar from cigarettes can cause deep permanent stains on your teeth. The teeth of people that smoke are often yellow or brown even immediately after they brush their teeth. It can be very difficult to get rid of those stains. Smoking also can weaken your teeth and give you cancer, so just don’t do it. It’s really not worth it.
Stop Drinking Soda
Any dark liquid like coffee, wine, or cola soda can stain your teeth. But soda also causes your teeth to break down because of the acid it contains. As the enamel on the tooth wears down the stains will get worse and eventually your teeth will be not only dark and stained but weaker than they should be as well. You should limit the amount of coffee and wine that you drink but stop drinking cola soda entirely if you want to save your teeth.
