Auraglow teeth whitening gel refills are designed for at-home tray whitening users who want professional-style whitening treatments without an office visit. The gel uses 44% carbamide peroxide, a peroxide-generating compound commonly used in dentist take-home whitening trays, to help lighten tooth discoloration caused by everyday foods and beverages. How the whitening gel works Carbamide peroxide gradually releases hydrogen peroxide and oxygen when applied to the teeth. The oxygen penetrates the enamel surface and breaks apart stain molecules trapped inside the tooth structure. This process helps reduce yellowing and deep staining associated with coffee, tea, red wine, soda, smoking, and natural aging. Because the whitening action occurs over time, repeated applications are typically used as part of a treatment cycle. Many users follow a daily whitening routine for approximately seven to ten days depending on stain level and desired shade. How to apply The gel is intended for use with a dental whitening tray. Place a small bead of gel inside the front portion of each tooth impression in the tray Insert tray and wear for approximately 20 to 30 minutes Remove tray and rinse mouth and tray after treatment The gel may also be applied directly onto teeth using a small brush or applicator when spot whitening specific teeth. Each syringe provides multiple applications, and the three-syringe refill pack offers approximately thirty full-mouth treatments when used as directed. Who it is for This whitening gel is commonly selected by users who have previously used tray whitening systems and want a higher-strength at-home whitening option. Individuals with known tooth sensitivity may prefer lower-percentage whitening gels or shorter wear times. Dental material compatibility The formula is designed for natural tooth enamel. Caps, crowns, veneers, and bonded dental work will not be damaged by the gel; however, dental restorations do not whiten and may remain the same color as before treatment. Flavor and manufacturing The gel has a mint flavor for comfortable wear and is packaged in sealed syringes to help maintain freshness and stability. The product is manufactured in the United States using dental-grade ingredients.
