Whitening Strips (7-day treatment)

Yes, clinical studies have shown that whitening strips with hydrogen peroxide are effective at brightening teeth and improving overall tooth color*. When used consistently, most people see noticeable results within 1-2 weeks*. For best results, always follow usage instructions and pair with a gentle oral care routine.

Results vary by individual, but clinical studies on hydrogen peroxide whitening show noticeable improvement after two weeks*, with many users maintaining a brighter smile for four or more months*. Continued care — including regular brushing, flossing, oil pulling and smart habits like limiting stain-causing foods — can help extend your results.

Yes, whitening strips are safe for most people when used as directed. Studies have shown they’re generally well tolerated, with only mild side effects like temporary tooth sensitivity or minor gum irritation* in some users. To help prevent discomfort or over-whitening*, it’s important to follow the usage instructions and avoid excessive or prolonged use.

Always follow the instructions provided with your whitening strips. Using them more often or for longer than recommended can increase the risk of damage* to the tooth and gums. Sticking to the suggested schedule ensures safe, effective results without discomfort.

Whitening strips work by using hydrogen peroxide to gently lift stains* from the surface of your teeth. As the peroxide penetrates the enamel, it oxidizes and breaks down* stain molecules, resulting in a visibly brighter smile*. This process does not harm your enamel* when used as directed, making whitening strips a safe and effective option for many people.

Most people start seeing noticeable results after just one week of consistent use. For best results, continue using the strips as directed for a full two-week cycle*. As with any new oral care routine, results may vary based on your individual enamel and lifestyle habits.

Always follow the manufacturer’s instructions for safe and effective results. With GuruNanda Whitening Strips, simply peel the strips from the backing film, apply them gel-side down along your teeth and press gently to secure. Leave on for 30-45 minutes for the express treatment or 60 minutes for the professional treatment. After removing, rinse your mouth thoroughly.

Whitening strips aren’t recommended while wearing braces. Since the strips can’t reach the areas beneath the brackets, you may end up with uneven whitening. Strips also need a snug, smooth surface to properly adhere — something braces can interfere with. For best results, wait until after your braces are removed to start your whitening routine.

It’s not advised to use teeth whitening products while pregnant or breastfeeding*. If you’re unsure or considering whitening during this time, it’s best to consult with your doctor or dental professional first.

If you experience tooth sensitivity after using whitening strips, try spacing out your treatments or taking a short break to let your teeth recover. Some studies suggest that taking ibuprofen beforehand* can reduce sensitivity, but be sure to check with your healthcare provider before trying anything new.
