No. 1: Yogurt Recent studies have shown that drinking yogurt on a daily basis can reduce the level of hydrogen sulfide in the mouth, the very substance responsible for making the mouth smell bad. Drinking yogurt on a regular basis can also stop the production of harmful bacteria in the mouth that can cause dental bed disease or plaque. However, only natural yogurt has this effect, sugary yogurt does not have this effect. The second: vegetables and fruits rich in fiber include apples, carrots and celery. These vegetables and fruits help to produce a lot of saliva. Saliva not only moistens the mouth, but also removes food debris that is attached to the top of the teeth or stuffed in the cracks. These food debris is also one of the causes of oral odor. The third: foods with a lot of vitamin C Berries, citrus, fining and other foods with a lot of vitamin C create an environment in the mouth that is not conducive to bacterial growth. Regular intake of vitamin C is also very useful for the health of the dental cavity. However, it is important to note that vitamin C should be consumed from natural foods, not food additives, which may disrupt digestive function. Fourth: Parsley This herb is most helpful in eliminating bad odors from the mouth, especially smoke. If you can’t find parsley on hand for a while, cilantro and mint leaves can serve to take out the bad taste in the mouth. For better results, the longer these things are chewed, the better, or used to make tea to drink. In addition, the above-mentioned herbs are also good for digestion.
