First of all, I don’t know why we need to brush our teeth with vinegar, brushing with vinegar is definitely harmful, because vinegar is an acidic substance, the teeth themselves are relatively weak against acid resistance, so if the acidic substance is retained in the tooth surface and the mouth for a long period of time, it may result in more dental caries. In general, we recommend brushing with our common toothpaste, the common ingredients of toothpaste are calcium carbonate and silicon dioxide, which is a better abrasive ingredient, it rubs with the tooth surface on the toothbrush, it will make the plaque on the neck of the tooth and the plaque on the tooth surface have good cleaning effect. At the same time, we recommend brushing with pasteurized brushes to clean the gums for good gum health. Therefore, we do not recommend brushing with vinegar.
