Children have different physiological characteristics at different oral development stages, so the brush head shape of Children's Growth Toothbrush needs to be designed specifically to ensure the oral cleaning effect and children's oral health.
During the eruption period of deciduous teeth, children's mouths are small and tender, so the brush head should be designed to be small and round. Such a shape can be easily put into the mouth, flexibly clean all sides of deciduous teeth, and avoid the pressure or damage of oral soft tissue caused by the brush head being too large. For example, the brush head can be designed to be similar to an oval, with a length of no more than 2-3 cm and a width of about 1-1.5 cm. The bristle area fits the arrangement shape of deciduous teeth and can effectively clean the gaps between teeth and tooth surfaces.
As children grow older and enter the deciduous dentition period, the mouth expands. At this time, the shape of the brush head can be appropriately enlarged, but still maintain a soft curve. A design that is approximately rectangular but with rounded corners can be adopted, with a length of 3-4 cm and a width of 1.5-2 cm. This shape is conducive to covering more deciduous teeth, and at the same time, it can ensure that the bristles are in full contact with the tooth surface when cleaning larger teeth such as molars, thereby improving cleaning efficiency. The top of the brush head can be slightly concave to better fit the shape of the dental arch and clean the teeth on the inner side of the mouth.
The tooth replacement period is a critical stage, and there are both deciduous teeth and permanent teeth in the mouth. The shape of the brush head should take into account the characteristics of both and be designed to be of moderate width. The front end of the brush head can be slightly narrower to facilitate deep cleaning of the erupting permanent teeth in the mouth, while the back end is slightly wider to clean multiple deciduous teeth or permanent teeth at the same time. The height of the brush head should also be moderate to avoid excessive stimulation of the gums and newly erupted permanent teeth when brushing.
In the early stage of permanent dentition, the oral cavity is basically mature, but the oral cavity of children is still more sensitive than that of adults. The shape of the brush head can be closer to that of an adult toothbrush, but the distribution of bristles and the contour of the brush head should be more in line with the dental arch and tooth arrangement of adolescents. It can be designed as a slightly curved rectangle with a length of about 4-5 cm and a width of 2-2.5 cm, ensuring that permanent teeth can be fully cleaned while protecting oral health.
In short, designing the shape of the brush head according to the oral development stage of children can make the brushing process safer and more efficient, and help children develop good oral hygiene habits.
