There are certain foods that cause staining and those must be avoided to get whiter teeth.Foods and beverages such as wine, tea, coffee, soda, and juices can stain your teeth. Acidic foods can make the teeth look yellow and wear down the enamel. You must either use a straw while drinking or brush your teeth at least 30 minutes after having any such foods.
Quitting smoking or other tobacco products can also help by reducing the stains from nicotine. Quitting can also provide other benefits such as reventing tooth decay and gum disease, both of which can damage the enamel and ause oral health issues in the future.
Eat less food with added sugar. Sugary foods seem delicious at the moment but can affect your teeth and dental hygiene in the long run. Sugar interacts with the bacteria in your mouth to produce acids which in turn make your teeth yellow. The best food to eat for whiter teeth includes fresh fruits and vegetables and dairy products such as cheese and curd which contain more calcium.
Your teeth may turn yellow with age, but a lot of different methods can slow this process or even reverse it. While teeth
whitening can be done using several products available on the market, many natural teeth cleaning home remedies can also help remove stains and protect your teeth from yellowing.
