Drinking tea regularly can increase the flow of water and liquid in the mouth and maintain oral hygiene. Sugar, pectin and other ingredients in tea react with saliva to moisten the mouth and enhance the self-cleaning ability of the mouth. Chewing tea can also cure gum bleeding. However, it should be noted that when chewing, you should chew slowly and let the tea be ground and chewed into fine powder in your mouth before swallowing saliva.
2. Onions: Onions, especially fresh raw onions, can kill many kinds of bacteria, including Streptococcus mutans, which causes our tooth decay.
3. Lentinus edodes: Lentinus edodes contains lentinan which can inhibit bacteria in the oral cavity from producing dental plaque.
4. Mustard: Mustard contains some ingredients that can inhibit the reproduction of Streptococcus mutans, which causes tooth decay.
5, celery: crude fiber food can sweep away some food residue on the teeth. In addition, hard chewing can stimulate saliva secretion, balance the pH in the mouth, and achieve natural antibacterial effect. Besides celery, sliced cucumbers and carrots can also massage the gums.
Drinking water is the simplest but most important way to protect your teeth. Moderate drinking water can make our gums moist and stimulate powdered saliva. Drinking some water after a meal can take away the food residue in the residual mouth and prevent the bacteria that damage the teeth from getting nutrition.
7. Sugar-free gum. Chewing sugar-free chewing gum containing xylitol has obvious effect on inhibiting bacteria causing dental caries.
