Crest 3D Whitestrips Age Renew At-Home Teeth Whitening Kit — 21 Treatments, Advanced Seal for No-Slip 60-Min Results

Crest 3DWhitestrips Age Renew is an at-home teeth whitening kit that removes up to 30 years of stains with 21 daily 60‑minute treatments.

Designed for people who want noticeable whitening without professional appointments, this kit uses Crest’s Advanced Seal Technology to keep whitening strips in place while you move, talk, or sip water. Each box contains 42 strips (21 upper, 21 lower) formulated with the same active whitening ingredient dentists use, and the treatment course is engineered to deliver professional-level results at home.

How long until I see visible whitening results?

Many users report a visible difference within the first week, with the full course designed for 21 daily applications. Results depend on current tooth color and types of stains, so individual experience will vary.

• Apply strips once daily for 60 minutes for 21 days.
• Some improvement often appears after several treatments.
• Maximum advertised removal (30 years of stains) reflects long-term surface stain reduction over the full course.

Will the strips stay on while I move around or drink water?

The Advanced Seal Technology provides a no-slip grip that helps strips adhere throughout the 60‑minute application. The design allows you to speak and sip water carefully without losing placement, but avoid chewing or vigorous mouth movement.

• No-slip adhesive holds strips during normal activities.
• Safe to talk and sip; avoid eating or biting while wearing strips.
• Follow removal instructions to prevent adhesive residue.

Are these strips enamel-safe and suitable for sensitive teeth?

Crest 3DWhitestrips Age Renew are formulated to be enamel-safe and use a whitening ingredient similar to what dentists use. However, whitening can increase tooth sensitivity for some users; sensitivity varies and should be monitored during use.

• Formulated for enamel safety when used as directed.
• Some users may experience temporary sensitivity; discontinue if severe.
• Follow package directions for correct application and removal to reduce issues.

How do I use the Age Renew strips correctly?

Clean and dry teeth before application, choose the strip size that fits each tooth row, press gently to adhere, and wear for 60 minutes daily. After removal, discard strips and rinse any remaining residue; complete the 21‑day regimen for best results.

• Brush and dry teeth before applying strips.
• Apply upper and lower strips as indicated; press to seal edges.
• Wear 60 minutes, then remove and discard; avoid eating until rinsed.

Who is this for: Crest 3DWhitestrips Age Renew is ideal for adults seeking significant surface stain reduction at home—people with long-standing coffee, tea, tobacco, or age-related discoloration who want a dentist‑level whitening option without office visits. It suits those willing to follow a daily routine for three weeks and who understand whitening can cause temporary sensitivity for some users. Not intended for children; follow all package instructions and consult a dental professional if you have concerns about sensitivity or existing dental work.
