Linhart NYC Tooth Whitener Gel

It is designed to be simple: just add a single drop of the gel directly onto your toothbrush alongside your regular toothpaste. Brush as you normally would, allowing the peroxide-based formula to work on surface stains while you clean your teeth.

Because this gel is designed to be used in small, controlled amounts during your regular brushing routine, it is generally gentler than high-concentration whitening strips or trays. However, if you have naturally sensitive teeth, we recommend starting with every other day to see how your enamel reacts.

While the gel is formulated to integrate seamlessly with any toothpaste, the brand recommends pairing it with their specialized toothpaste and antibacterial toothbrush for optimal results. Using their full system ensures the ingredients are compatible and the application is consistent.

Consistency is key with this product. Most users begin to notice a subtle brightening of surface stains within a few weeks of daily use, though individual results depend on your starting shade and the types of stains present.

Whitening gels, including peroxide-based formulas, are generally designed to whiten natural tooth enamel and typically do not change the color of dental restorations like crowns, veneers, or fillings. If you have significant dental work in visible areas, consult your dentist before use to avoid uneven coloring.
