Signal from Germany belongs to the global fast-moving consumer goods giant Unilever Group, and like Putzi, it belongs to the German children's toothpaste that is well-known in China.

For children under the age of 6, Signal is equipped with 500pm fluoride, which is free of peppermint oil and sugar, and has a milder taste and is easier to rinse, so it can be safely used by young children who are not familiar with gargling and swallowing. The specifications and price of this model are comparable to Putzi, and the price is 20 yuan a piece, which is also a cost-effective choice among foreign brands.

For children aged 6-12 years who are at higher risk of tooth decay during tooth replacement, Signal provides a fluoride content of 1450ppm, which is comparable to the protection of adult fluoride toothpaste, and is a professional anti-caries calcium toothpaste. It is worth noting that the fluoride content of 1450ppm has exceeded the recommended fluoride content of children's toothpaste in most countries, and it needs to be selected according to the specific guidance of dentists, and parents are not recommended to buy it themselves.

Similar to Putzi, Signal's packaging is still colorful and playful with a fun cartoon image, and it is also divided into two categories: powder and blue according to the male and female babies, and the paste is a crystal two-tone gel, which is very flattering. In terms of flavors, Signal has also launched a special ice cream flavor, which is more appealing to babies who don't like regular fruit flavors.
