Opalescence Teeth Whitening Trays 10-Pack, 15% Gel & Sensitive Toothpaste 4.7 oz, 15–20 min

Opalescence GO 15% is a ready-to-use teeth whitening kit with ten prefilled UltraFit trays and a sensitive-formula toothpaste to brighten teeth in about 15–20 minutes per wear.

This kit pairs dentist-developed 15% hydrogen peroxide gel in prefilled, form-fitting trays with a 4.7 oz Opalescence Sensitive Whitening Toothpaste designed to support results while minimizing discomfort. The UltraFit trays adapt to a variety of smiles without the need for boiling or molding, and the routine is simple, portable, and suitable for short daily sessions.

How quickly will I see a difference with Opalescence GO 15%?

Most users notice visible improvement after a few consecutive treatments, with progressive whitening across the 10 included applications. Each wear lasts roughly 15–20 minutes, allowing you to fit sessions into a busy day without long overnight use.

• 10 complete treatments: one upper and one lower tray per session.
• 15% hydrogen peroxide gel for efficient stain lifting.
• Typical wear time: 15–20 minutes per treatment.
• Progressive results across multiple sessions—best results after completing the series.

Will these trays cause sensitivity and how does the toothpaste help?

Opalescence GO is formulated with sensitivity reduction in mind and the included Sensitive Toothpaste helps maintain whitening while being gentler on sensitive teeth. The toothpaste is sweetened with xylitol and is free from gluten; it supports enamel-friendly care and helps reduce decay risk while you whiten.

• Opalescence Sensitive Toothpaste (4.7 oz) complements whitening treatments.
• Xylitol-sweetened formulation to help lower cavity risk.
• Designed to be low-sensitivity while supporting whitening maintenance.
• Gluten-free and kosher-certified ingredients.

How do the UltraFit prefilled trays work and do I need extra tools?

The trays arrive preloaded with whitening gel and are manufactured from a flexible material that conforms to most tooth shapes without heating or molding. No LED lights, special trays, or dental appointments are required—simply insert, wear for the recommended time, and discard after use.

• Prefilled trays: no messy syringes or tray-filling required.
• UltraFit material molds comfortably to a range of smiles.
• No LED lights or additional devices needed or recommended.
• Portable sachets make treatment convenient for travel or quick at-home sessions.
