In the Chinese oral care market, Black is one of the few local Chinese brands that can compete with Colgate. In 2012, the market share of black toothpaste surpassed Colgate and Crest to become the first in the Chinese market, and it also has a large market share in Southeast Asia.
 
Although the main product is toothpaste, blacks are also quite strong in the field of toothbrushes, adult toothbrushes mainly have excellent cleaning, whitening series, gum protection and anti-allergy care series, deep cleaning series and source wood series, many and complete products, almost covering major supermarkets, but e-commerce sales products are limited, and they are all soft bristles, and there are not many options.
 
Some black toothbrushes are more similar to Colgate and Oral-B, such as the charcoal rotation double clean with cross-arranged bristles, and the gum care series smart gum care toothbrush that uses indicator bristles, but the price is more advantageous, and the average price of the combination is less than 10 yuan.
 
The black main carbon silk antibacterial toothbrush, excellent clean series contain carbon elements, in fact, whether it can play a role in the claim of utility needs to be doubtful, whether it is the flat bristles of the carbon silk spin cleaning or the cross bristles of the carbon spin double clean, it can be used as an ordinary toothbrush, the price of a single carbon spin double clean is about 8 yuan, 2 yuan higher than the price of carbon silk spin cleaning. The tips of the bristles of the deep cleaning series are 0.01mm, and the gap between the teeth can also be deeply cleaned, and the 29mm standard brush head is about 5 yuan, and there is a 26mm small brush head.
 
The gum care series focuses on small brush heads and high hair density, and the high-density toothbrush with 4,000 hairs specializes in gum care, and the number is almost the same as that of 4,100 fine-toothed gum cleaning, and the unit price is about 8 yuan, which is slightly lower than that of fine-tooth cleaning. The same series of feather protection Qiaojie is a small brush head toothbrush below 20mm, the brush handle has no anti-slip design, and the price of a single piece is close to 13 yuan, which is not cost-effective.
 
Relatively speaking, the whitening series of white rubber wool equipped with TPU is not easy to clean between the teeth, the source wood series using the wooden brush handle is not as comfortable as the brush handle wrapped in soft rubber, and it is easy to slip, and the practicality is not high, the single white of the white gum is 13 yuan, and the source wood series is close to 24 yuan, and it is not recommended for consumers who do not have a special preference for these elements to buy.
 
The children's toothbrush series, the Elf Baby Rabbit and the Cute Baby Rabbit are all children's toothbrush series, and compared with the latter two series with a wide age division, the more detailed stage division of the Legu Tooth series is recommended. The Legu tooth series is divided into three stages: 2-6 years old, 6-10 years old and over 10 years old, and the size gradually increases to meet the needs of children's growth and development.
