If your teeth are sensitive after brushing it may be because you are applying too much pressure or doing it too often. Learning the right techniques along with brushing twice a day, every day, with Sensodyne can help.

Professional bleaching treatments may cause you to experience sensitive teeth after whitening, but this is only temporary. Some at-homewhitening remedies can make tooth sensitivity worse.

Enamel is the hard, outermost surface of the tooth. Over time, if tooth enamel wears a way, the dentin can become exposed, which may lead to sensitive teeth. It may be caused by acid erosion.

Healthy gums are essential for healthy teeth. If gums recede, dentin becomes exposed, making the tooth nerves vulnerable to triggers, causing sensitivity.
