Brushing teeth is what we need to do every day. Some women who love hygiene brush their teeth three times a day. Are you really right? Do you need water before brushing? What are the common mistakes of brushing teeth?
Should the toothbrush be watered before brushing
General toothpaste: no water!
The toothpaste used by most people mainly includes surfactants, foaming agents, wetting agents, thickeners, aromatics, preservatives and so on. For example, surfactants and foaming agents need water to function.
If you don't get water on your teeth, you can't clean them completely. Isn't it white brush!
Concept toothpaste: desensitization toothpaste, whitening toothpaste, etc., do not touch water!
Some concept toothpastes on the market have special functions. For example, toothpastes containing antiallergic ingredients, whitening ingredients and periodontal disease care ingredients will release active ingredients rapidly when exposed to water. Dry brushing is recommended.
There is a way to get the best of both worlds: rinse your mouth a little before you brush your teeth, and brush after your mouth is wet; or dip water in the cup before you brush, but the disadvantage is that the toothpaste is easy to slip.
