1, put baking soda when brushing your teeth.
We all know that baking soda has a strong cleaning effect, so putting some baking soda properly when brushing your teeth can also help us clean. If you keep this habit for a long time, your teeth will become whiter and whiter, but whitening also needs a process. We should be patient. Generally, it may take about three months to get the effect.
Step 2 wash your teeth
If you haven't washed your teeth for a long time, you can also try to whiten your teeth by washing your teeth, because the food and bacteria left in the gaps between your teeth will form dental calculus, which can't be removed in the ordinary brushing room, so you need to clean your teeth by washing them, so that your teeth will look whiter.
Step 3 use whitening toothpaste
Many whitening toothpastes contain ingredients that help us whiten our teeth, so we can choose some whitening toothpastes to brush our teeth properly. However, it should be noted here that when choosing toothpaste, we should try our best to choose according to our oral conditions. For example, if we have mild gingivitis, we can choose a toothpaste with whitening effect to treat gingivitis.
