Increase the amount of lighting directly over the task that you are
doing. Focus the light directly onto what you are doing. LED lights,
natural light and natural daylight bulbs are recommended. Do not use
fluorescent lights as fluorescent light causes glare.
Use colored or striped toothpaste as these are easier to see on the
white bristles of a toothbrush. Or, simply squirt the toothpaste
directly into your mouth and brush!
