In dental terminology it is called as Dentinal Hypersensitivity which means a dental pain which is sharp and of short duration, arising from exposed dentinal surfaces in response to stimuli, typically thermal, evaporative, tactile, osmotic, chemical or electrical and which cannot be ascribed to any other dental disease.

Sharp and sudden pain, in response to any external stimuli. Most people experience this type of pain with cold stimuli. Hot and cold drinks and foods.

Frequent intake of cold and hot drinks and foods. Tooth wear off which can be due to age progression, traumatic bite, uneven occlusal forces(while eating/during anxiety) Gum recession (which can due to excessive or forceful toothbrushing or abrasive toothpaste, or a sign of periodontal disease, position of tooth/teeth)

Tooth erosion (which is due to gastric acid reflux, excessive intake of acidic foods or beverages) Dental procedures like composite fillings, dental bleaching. Tobacco smoking. Cracked/Fractured tooth/teeth(due to heavy occlusal forces/trauma) Abfraction(wedge shaped defects) or grinding of teeth(bruxism) Tooth decay (in which decay of enamel layer is worn away and reaches to dentin layer causes sensitivity to sweet foods, cold or hot foods or beverages)

Desensitizing toothpaste can be used under the guidance of dentist. After prolonged use of the toothpaste & mouthwash for minimum of 15-30 days difference can be observed. Warm water with a pinch of salt also can help the mild teeth sensitivity.

Fluoride Varnish may be advised by the dentist if toothpaste does not help.

Heat Sensitivity occurs when there is an access or infection underneath the tooth. This condition should not be ignored and consulting a dentist is a must.

Malocclusions like deep bite, cross bite usually will lead to enamel deterioration at a young age and the first sign they notice is teeth sensitivity. Do not ignore the signs of teeth sensitivity. It is something your teeth are telling in advance that there is an issue, please correct me! Visiting a dentist will help you understand what exactly is happening with your teeth and why is it happening? once you have the answers to these questions, you can decide the best course of action in consultation with your dentist and get the treatment done.
