Best whitening tray: Sporting Smiles Teeth Whitening Trays
- Price: $80
- Type: tray
- Active ingredients: 22% or 35% carbamide peroxide
- How long it lasts: 6–8 months, results can vary
This teeth whitening kit uses a custom-made tray and foaming whitening gel. A person must take impressions of their teeth using the dental putty and impression trays included in the kit and send the impressions back to the company.
Sporting Smiles will then make custom whitening trays from the impressions and ship them to the customer. The customer can then use the trays and foaming gel to whiten their teeth.
The gel can remove stains from coffee, tea, wine, and tobacco. Sporting Smiles says a foaming gel will bubble and access typically hard-to-reach areas of the teeth.
While some people found the kit affordable, easy to use, and efficient, other buyers found it hard to make accurate impressions. Many customers report long waiting times for their custom trays to arrive.
