1. Look at the packaging. Including toothpaste boxes and toothpaste tubes. The box and tube of real toothpaste are neatly packaged, the printed fonts are clear, the tube is straight, and the tooth pattern at the end of the tube is neat and orderly without damage. Although today's fake toothpaste is so fake that it looks like the real thing, but in terms of details, you can still find clues as long as you look carefully.

2. Smell. Real toothpaste smells like a natural fragrance. If you smell a pungent and unpleasant chemical smell, it means you have bought fake toothpaste. This smell is especially noticeable when brushing your teeth.
