Abstract
An anti-dental injury toothbrush is disclosed. The toothbrush of this invention has a long handle (1) and a brushing head (2) formed on one end of the long handle (1). A plurality of soft bristles (22) are set on the brushing head (2) thus forming two opposite soft bristle parts, with a longitudinal gap being formed between the two soft bristle (22) parts and having a width similar to the thickness of a tooth. A plurality of hard bristles (21) are set on the brushing head at positions outside the two soft bristle parts thus holding the soft bristles (22). The hard bristles (21) are made of a plastic material harder than a material of the soft bristles (22). The toothbrush of this invention is free from injuring the teeth or gum while brushing the teeth.
