About vibrations...: Problems with excess vibrations will vary with the duration of the activity, the intensity of it, and the individual person. Vibration can damage nerves, so people use gloves to damp vibrations (note workers' gloves as they use jack hammers to break up concrete). Probably a teen should use toothbrushes only for brushing teeth. A teen should be able to heal up fine from toothbrush vibrations.
