1. Onion
For individuals with severe dental plaque, it is advisable to consume more onions in daily life. Some substances in onions not only help protect oral health but can also effectively remove dental plaque. Research has found that onions contain a large amount of sulfur compounds, which are powerful antibacterial ingredients that are very effective in preventing and killing various oral bacteria. Furthermore, in vitro experiments have shown that onions can kill *Streptococcus mutans*, the bacteria that causes cavities.
When eating onions, it is best to eat them raw. Eating half a raw onion daily not only helps prevent cavities but can also effectively lower cholesterol, thereby preventing various chronic diseases like heart disease.
2. Celery
Celery is a very common stem and leaf vegetable in our daily lives, and many people also use it as a breath freshener. However, the effect of celery on the mouth is not limited to this. In fact, when you chew celery vigorously, it is giving your teeth a deep clean, while also significantly reducing the risk of cavities. This is because celery contains a large amount of coarse fiber, which acts like a broom, sweeping away food particles from your teeth.
Moreover, the more you chew, the more it stimulates saliva secretion, which helps balance the pH level in your mouth. When saliva is in a balanced pH state, it can better perform its antibacterial and germ-killing functions.
3. Shiitake Mushroom
Shiitake mushrooms are a type of edible fungus that many people enjoy eating. Recent research has found that regularly consuming shiitake mushrooms can effectively help prevent cancer. Therefore, in our daily lives, we should eat more shiitake mushrooms to prevent the formation of cancer cells. While eating shiitake mushrooms, they can also help remove dental plaque because they have a very protective effect on teeth. The reason they can protect teeth is that shiitake mushrooms contain a large amount of lentinan, which can inhibit the formation of dental plaque.
There are many ways to eat shiitake mushrooms. Due to their unique flavor and low calorie content, they are delicious whether in soups, stir-fries, or cold salads. To maintain healthy teeth, shiitake mushrooms are an indispensable food.
4. Green Tea
Cultivating a habit of drinking green tea regularly in daily life can also effectively remove dental plaque. This is because green tea contains a large amount of fluoride, which can combine with the hydroxyapatite in teeth to provide acid resistance and prevent cavities. Furthermore, green tea contains a large amount of catechins, a substance that can reduce *Streptococcus mutans* in the mouth and also help eliminate bad breath.
There are many ways to remove dental plaque. The methods mentioned above are the most effective and simplest in daily life. Therefore, people with dental plaque should eat more of these foods. Additionally, one should develop the habit of brushing teeth in the morning and evening, which can also prevent and remove dental plaque.
