Is there any difference between over-the-counter tooth whiteners and Rembrandt or Opalescence?
Yes! Consulting Dr. Alb is always the first step to whitening your teeth safely. Over-the-counter tooth whitening strips, brush-on gels and toothpastes take weeks or months to whiten your teeth just a few shades. Rembrandt is clinically proven to whiten your teeth eight to ten shades in one hour; Opalescence is six to eight shades in just one weekend.
