Your Questions About Tooth Whitening Products
Carbamide Peroxide consists of H202(hydrogen peroxide, the active ingredient) bonded with urea. Our 44% carbamide peroxide consists of 15.8% H202. Therefore, it’s about half the strength of the 35% H202. We found this concentration to be a viable in-office option as it can produce in-office results on the upper arch without the need for a rubber dam.
The shelf life of the at-home bleaching material is 1year. The bleaching material should be kept refrigerated. In-office materials should also be refrigerated and replaced about nine months after the date of purchase.
Our experience has shown that about 5% of patients are sensitive to carbamide peroxide. This percentage of sensitivity appears to be consistent through concentrations of 10%, 15%, 20% and 30%.
If a patient experiences pulpal symptoms, i.e. minor tooth sensitivity (nationwide surveys show less than 5% occurrence of such sensitivity with all at-home peroxide based bleaching agents), instruct them to discontinue treatment for 48 hours, and then resume treatment with 1/2 cc of material in the tray for one hour, once per day. The majority of such symptoms are transient and regress within about 48 hours.
We suggest that you have the patient place 1/2 cc of the material into the stent and wear the stent for 30 minutes. Twice-a-day applications is all that is required. Send the patient home with enough material (i.e. one 5.5cc syringe) to begin the upper arch. Bring patient in for a mid-treatment recall before sending him/her home with the remainder of bleach (sometimes in a higher concentration) to complete the arch. A mid-treatment exam is optional. After completion of the upper arch, then repeat the process for the lower arch.
We are licensed under Patent Re: 34,196 which covers a method of tooth bleaching that involves placing bleaching material into a dentist designed mouth tray. We extend that patent protection in conjunction with the use of our products to our dentists’ customers.
