Especially the interdental spaces are difficult to reach with conventional toothbrushes. Here, plaque can easily settle and lead to the formation of tooth decay. The Dr. Best high-low manual toothbrush supports you with the help of the high-low cut for thorough and gentle cleaning. The shorter rows of bristles clean the surface of the teeth, while the longer bristles are designed to clean between the teeth. In addition, the rounded bristles are gentle on the gums. The special spring gives off when pressure is too high, helping to protect your gums from injury.
