Dental hypersensitivity or hypersensitive teeth is a disorder that causes acute, short and transient pain to stimuli such as cold or heat. This occurs when the tooth enamel undergoes a change. Dental hypersensitivity may be mainly caused by improper brushing, caries, periodontitis, receding gums, mucogingival surgery, teeth whitening or acidic foods. The pain appears to stimuli but when it is removed, all the pain disappears in a moment. Treatment to combat hypersensitivity may be to use toothpaste for sensitive teeth and change the way of brushing. If this fails, the dentist can apply a coat of enamel on the tooth surface or if the pain is too intense, can choose to kill the nerve.
