China Customized Bleaching Tray Factory

A bleaching tray represents a prosthodontic-grade oral appliance custom-fabricated for professional tooth whitening. Constructed from flexible thermoplastic materials such as EVA or polyethylene, this appliance is precision-molded from a dental impression to ensure intimate adaptation to the dental arch. It serves as a delivery system for carbamide peroxide or hydrogen peroxide gels, facilitating controlled release of whitening agents directly to tooth surfaces. The custom-fit design creates a sealed microenvironment that enhances enamel penetration while minimizing gingival irritation. By enabling targeted delivery of whitening compounds, this prosthetic appliance achieves accelerated bleaching of dental enamel, making it a preferred solution in both in-office and at-home professional whitening protocols.

How does a bleaching tray work?

A bleaching tray works by delivering whitening gel to teeth in a controlled manner. Here's the step-by-step mechanism:

Custom Molding for Precision Fit
Made from a dental impression, the tray's shape conforms to the patient's dental arch, creating a sealed barrier around teeth. This prevents gel from leaking onto gums and ensures uniform contact with enamel.

Active Ingredient Delivery
The tray holds carbamide peroxide or hydrogen peroxide gel. When worn, these chemicals break down to release oxygen, which penetrates tooth enamel and breaks down pigment molecules (e.g., from coffee, tobacco, or tetracycline stains).

Controlled Whitening Process

In-office trays: Pair with high-concentration gels (15–40% peroxide), activated by light or heat to accelerate oxygen release for rapid whitening.

At-home trays: Use lower-concentration gels (5–22%) for gradual whitening over 30 minutes to overnight, minimizing enamel irritation.

Safety Mechanisms
The tray's design limits gel exposure to teeth, reducing gum irritation. Its reusable nature (6–12 months) allows consistent, monitored whitening without overuse, which could cause sensitivity.

By combining a custom fit with controlled chemical delivery, bleaching trays enable targeted whitening while protecting soft tissues, making them a safer alternative to over-the-counter strips for professional results.
