Though a higher percentage of carbamide and hydrogen peroxide may prove harmful for the teeth enamel, but the fluoride content of the formula removes the side effects to a considerable extent. Dentists also prescribe fluoride gels to those using a higher concentration of these whitening materials which help as a protective cover.

In case of acute sensitivity or gum irritation, one may discontinue the usage of the teeth whitening agents on a regular basis and use it on alternate days. The agent may also be applied for lesser time. The in-office, at-home or over-the-counter teeth whitening agents may result in tooth sensitivity and irritation of the gums.

Whereas prescription fluoride is a good remedy for sensitivity, over-the-counter products like Orajel treat gum irritation well. Some dentists complain of the loss of patients as well as revenues as they hold the large companies with a vast array of over-the-counter teeth whitening products responsible as being the root cause for this loss.

On the contrary, these products help create awareness and enthusiasm among the masses about tooth whitening and cosmetic dentistry and in turn this helps the dentists. In fact one of the ads suggests consulting with the dentist and taking their opinion about the cosmetic dental options and it gives a brief description about these teeth whitening procedures.
