Crest 3D Whitestrips Teeth Whitening Strips, 2-Week Smile Transformation — 16 Treatments, Enamel-Safe

Crest 3D Whitestrips 2 Week Smile Transformation is an at-home enamel-safe whitening kit that removes years of stains and can make teeth up to 11 shades whiter in two weeks.

Designed by the dentist-recommended Crest brand, this kit includes 16 treatments (32 strips) formulated with the same enamel-safe whitening ingredient used by dental professionals. The strips use Advanced Seal Technology to stay in place so you can continue light activities like talking or drinking water while whitening. This product targets long-standing, set-in discoloration from coffee, tea, tobacco and everyday foods.

How quickly will I see results?

Most users notice visible improvement within the first week, with the full 11-level change achievable after completing the two-week regimen. Results depend on the original shade and the type of stains being treated.

• Visible changes often appear within 3–7 days.
• Full effect after finishing all 16 treatments over two weeks.
• Consistent daily application ensures uniform whitening.

Are these strips safe for enamel and daily use?

Yes — Crest 3D Whitestrips are formulated with the same enamel-safe whitening ingredient dentists use. They’re intended for the recommended treatment schedule and are made to minimize harm when used as directed.

• Uses a dentist-grade, enamel-safe whitening agent.
• Designed for the two-week treatment schedule included.
• Follow package instructions to reduce sensitivity risk.

Will the strips stay in place while I talk or drink water?

The Advanced Seal Technology provides a non-slip grip, keeping the strips adhered during normal activities. That means you can speak and sip water without needing to readjust the strips frequently.

• No-slip seal helps maintain contact with teeth during wear time.
• Strip design covers both upper and lower teeth for even treatment.
• Remains effective while performing light tasks during treatment.

What does the kit include and how is it used?

The box contains 16 treatments (32 strips): one upper and one lower strip per treatment. Remove the strip from its backing, press it onto clean, dry teeth, and wear for the recommended time each day until the two-week course is complete.

• 16 treatments total — enough for a full two-week program.
• Each treatment includes one upper and one lower strip for full-arch coverage.
• Daily application; follow enclosed directions for best results.
