How to whiten yellow teeth caused by smoking?

People who smoke frequently will find that their teeth turn yellow easily. If your teeth turn yellow, you can drink more green tea or brush your teeth with baking soda, which can have a certain effect of whitening your teeth. At the same time, you should also pay attention to eating more green vegetables.

1. Brush your teeth with baking soda

When brushing your teeth, add some baking soda to the toothpaste, do not touch water, and gently brush the surface of the teeth. This can effectively remove tooth rust and increase the whiteness of the teeth. Baking soda is edible, but it is an alkaline substance, so you should not brush your teeth too hard, otherwise it will easily damage the delicate muscles in the mouth, which will not only cause pain but may also harm your health. This method has theoretical support from a chemical perspective, but it is still recommended that you do not always use it, as excessive intake of alkali is not good for the body's internal balance.

2. Drink more green tea

The tannins in green tea prevent bacteria from sticking to your teeth, which can cause staining, and also help prevent bad breath. The polyphenols in green tea can prevent the oral cavity from becoming sour and prevent bacterial growth in tissues. Green tea can also increase oral fluoride levels and reduce tooth enamel damage.

3. Brush your teeth and floss frequently

Preventing your teeth from discoloring is easier than removing it. Brushing and flossing are important for keeping your teeth white. Keeping this habit in mind can help keep your teeth from discoloring for a long time.

4. Eat more dark green vegetables

The minerals contained in dark green vegetables such as spinach and broccoli can help form a protective film on the surface of teeth and prevent teeth from turning yellow. Experts also recommend eating more apples, pears, celery and carrots, as chewing can promote saliva secretion, reduce oral bacteria and help whiten teeth.
