Loss of tooth substance reduces the RDT giving rise to persistent pain and sensitivity in the affected teeth. Tooth brush abrasion can cause the gum margin to recede and expose the root surface, causing gingival recession. Incorrect brushing technique is the culprit. Gingival recession can lead to cervical hypersensitivity and cosmetic insult. Sensitivity at the necks of the teeth can be persistent and annoying.
Hyperemesis gravidarum in the first trimester of pregnancy can cause the acidic vomitus to erode the lingual surfaces of the upper front teeth, leading to sensitivity and dental erosion. Soft drinks can also be a cause of erosion. Another cause for attrition is audible bruxism. Bruxers generally grind their teeth at night and wear out the occlusal surfaces, which leads to increased sensitivity. Bruxism is a parafunctional oral habit, which has a psychosomatic etiology. The patient requires multidisciplinary management to address psychological stress and dental management. It is generally the partner who hears the grinding sound and this input could be valuable in diagnosis.
