Dental sensitivity following teeth whitening is an incredibly common side effect, with up to two-thirds of people complaining about painful teeth following the procedure. Fortunately, you don’t have to be one of them. Consult the guide below for more information on what causes dental sensitivity after teeth whitening and how you can prevent this unpleasant phenomenon. 

What Causes Sensitivity After Teeth Whitening? 

There are two kinds of dental stains: intrinsic and extrinsic. While extrinsic stains can be removed by cleaning away plaque and tartar deposits, intrinsic stains can only be lightened through teeth whitening. During this procedure, the dentinal plugs that block fluid from moving through the pores in the dental enamel are released, allowing whitening agents to access the inner portion of the tooth and lighten the underlying dentin. Unfortunately, this reaction also causes mild pulpitis, which leads to dental sensitivity. 

The discomfort experienced during teeth whitening is more common in people who whiten too often or for too long, which is why working with a qualified dentist is the most appropriate course of action. In addition to checking your teeth carefully for decay, they will also prescribe a gel strength that is appropriate for your level of discoloration. 

How Can You Prevent Discomfort? 

Fortunately, a dentist can help you prevent sensitivity altogether by applying special desensitizing varnishes before and after the treatment. Special toothpaste brands that contain potassium nitrate can also help ward off sensitivity, as these products are designed to temporarily block the tubules released during whitening sessions.
