In the first 24 hours after whitening treatment, you may experience some tooth sensitivity. Sensitivity amongst individuals can be very unpredictable, and is usually very mild. Sensitivity from teeth whitening is a very different kind of sensitivity to what you may receive on a normal day. Normal sensitivity is usually due to hot or cold foods, whereas sensitivity in teeth whitening is usually due to the tooth drying out. It tends to be very unpredictable, and if you experience every day sensitivity it does not necessarily mean you will experience sensitivity with whitening.
Sensitivity in teeth whitening tends to last 1-2 seconds, and can be described as a ‘jolt’ coming from a tooth. We do have one of the lowest rates of sensitivity on the market, and if you do receive it it does generally lasts 12-24 hours. It goes away quickly and by itself.
