Whitening, or dental bleaching, is a very popular procedure and patients have numerous options when it comes to brightening their smiles. Over the counter options abound, but office assisted dental bleaching kits contain more powerful whitening formulations—often high concentrations of carbamide peroxide. Some of these kits are for use only in the dental practice, while others can be sent home with the patient who can use them in custom fitted trays. Whitening services from these in-office bleaching kits can provide a boost to a practice, but it’s important to use these materials properly to ensure patient safety.
