The toothbrush should encourage brushing of all tooth surfaces, in addition to not damage the enamel. Therefore, the bristles should be plastic and rounded edges that help protect enamel and gums.
The hardness, density and angle of the bristles will condition, by far, the effectiveness of the brush.
Please bear in mind that the child brushes are smaller and have the right design for each age, but maybe you can use as a brush support to get the back molars of all, because with a larger brush is more work because it may not fit well between the tooth and the cheek.
Electric toothbrushes are as effective as traditional, not because they clean better power, but they are very suitable for low-skilled, children, disabled and elderly.
Recommendations for choosing your brush:
* The brush head should be small and narrow with many bristles.
* Look for brushes with synthetic bristles, and they accumulate less bacteria than natural.
* Flaxibles sows must be finite and smooth rounded.
* Choose a brush with long handle, thin and somewhat flexible for softer brushing.
* Remember to change your toothbrush every three months.
