| Message: | The shape of the brush head is generally square and diamond. The square brush head can effectively clean every surface of the teeth. The tip of the diamond-shaped brush head is sharper than the square design, and it is easier to clean the oral cavity. A toothbrush with any shape of brush head can clean teeth, but the size of the brush head must take into account factors such as mouth size, mouth opening degree and personal habits. Try to use a small brush head so that it can penetrate deep into the mouth, ensure flexible rotation, and clean the back teeth. But there is no uniform standard. Children's oral cavity should choose a children's toothbrush that meets their age.
The choice of bristles should be moderately soft or slightly soft. But be aware that bristles that are too soft are not easy to clean. The bristles are mostly made of nylon yarn. Can be simply divided into-domestic brush wire and imported brush wire. The imported brush wire has good elasticity and is not easily deformed. The material of sharpened wire is PBT. Brushing is also important. If the bristles are not smooth after cutting, they may be too sharp and cause injury. A bristle toothbrush with rounded bristles can prevent this kind of injury and protect the gums better. url:http://www.samemater.com |
