Probiotic powder generally does not whiten teeth, but using probiotics can help alleviate bad breath. For teeth whitening, whitening strips or ultrasonic dental cleaning can be used. When using whitening strips, applying them directly onto the teeth can gradually whiten them. Ultrasonic dental cleaning uses high-frequency vibrations to remove plaque and tartar from the teeth, thereby making teeth appear whiter.
