Use a special electric toothbrush
An electric toothbrush is the top natural teeth whitener that Mark Burhenne, DDS, recommends. Oscillatory electric toothbrushes are the best at removing stains for natural teeth whitening, according to Dr. Burhenne. The motion of the bristles breaks up the pellicle or film on your teeth. “A thick pellicle will speed the staining process, so it’s a good idea to break it up with an electric toothbrush if you’re trying to expose your brighter teeth,” he says.
