Do sonic toothbrushes whiten teeth?

In general, the answer to this question is yes. Sonic toothbrushes are capable of removing stains by polishing away external stains that collect on the outer surface of the enamel, improving the overall appearance of your teeth and helping to support your teeth whitening journey. When your tooth has discoloration it is a combination of stains on the outside surface of the teeth and stains within the inner layers of the tooth. It has been proven that over time Sonic toothbrushes produce better stain removal results than manual toothbrushes.
