When it comes to achieving a brighter smile, many people find themselves torn between Crest Whitestrips vs whitening toothpaste. Both are widely available and claim to whiten teeth, but their active ingredients, methods of action, and results vary significantly. This guide will break down everything you need to know to help you make an informed choice.
Key Differences in Whitening Ingredients

Crest Whitestrips are thin, flexible strips coated with a whitening gel. Their active ingredient is typically hydrogen peroxide, which penetrates the tooth enamel to remove deep-set stains.

How It Works:
- Breaks down stains below the surface

Common Ingredients:
- Baking soda (sodium bicarbonate)
- Silica (abrasive)
