Brushing Habit - Improper brushing techniques, brushing your teeth aggressively in a horizontal fashion, especially with a hard-bristled toothbrush etc. can result in Tooth Sensitivity.

Tooth Decay - Plaque contains bacteria, which produce acids erode your tooth enamel, gradually leading to Tooth Sensitivity.

Use of Teeth-Whitening Therapy / Toothpaste - Sensitivity can be a temporary side effect of teeth- whitening treatment. Frequently use of improper at-home- whitening products can also cause Tooth Sensitivity.

Gum Problems - Gum Recession, a common problem in people over the age of forty, can cause sensitivity. Also, excessive flossing can damage your gums causing Sensitivity.

Cracked / Split Tooth - A Cracked Tooth can cause pain when you chew or bite on hard substance and can result in Tooth sensitivity.

Recent Dental Restorations - You may experience temporary Sensitivity after you have done dental treatment, but this would subside within four weeks.

Sinus Infection - A Sinus Infection can make your teeth hurt or sensitive when you do certain activities like jumping, brisk walking etc. This is due to the pressure and inflammation in the Sinus.

Cold Weather - When teeth come in contact with cold air, it can trigger a sensitive tingle.

Bruxism - Bruxism is grinding of the teeth during sleep, which can cause wearing of tooth enamel, resulting in Tooth sensitivity.

Chewing on Ice - If you are in the habit of chewing on ice, it can damage the nerves inside your teeth resulting in Tooth Sensitivity.

  1. Enamel erosion can expose the dentin and cause Tooth Sensitivity. Your dentist will identify the underlying causes of Sensitivity and recommend suitable interventions like Fluoride therapy, Gingival Graft Surgery etc.
