Dentinal Hypersensitivity

An unfortunate consequence of whitening either over the counter and professional bleaching is sensitivity. In professional whitening the carbamide peroxide and the water penetrate both the enamel and dentin without producing adverse effects on the enamel. A recent journal article in Dimensions of Dental Hygiene revealed that two clinical cases showed that over the counter whitening products did damage the enamel significantly.  In either option the application of topical fluoride after whitening was able to restore the mineral content and hardness of teeth back to the enamel’s original hardness.
