What Causes Sensitive Teeth And How Can I Treat Them

Tooth sensitivity is a major cause for which the patients visit to the dental clinic.  Teeth sensitivity refers to the sudden sharp feeling experienced when eating something cold. It is experienced particularly on teeth which have worn out or damaged enamel portion which leads to the exposure of the underlying layer(called as dentin). This layer has nerve endings which are extremely sensitive to temperature changes. The sudden temperature change triggered by consumption of cold food stimulates these nerves which in turn carries the sensation to the brain which interprets it as a sensation of cold.

Sensitivity to cold is reversible. Today there are a number of over the counter tooth pastes and mouthwashes available which are quite capable of treating this sensitivity. Regular use of these forms a protective layer over the exposed surface of dentin which prevents the nerve endings from being stimulated. However they should be used under the supervision and guidance of a dentist only. Where possible such teeth can be repaired using filling materials too which again shields the dentin from the outer environment.

Excessive damage to the dentin layer however makes the things irreversible. At this stage the tooth becomes sensitive to both hot and cold sensations. Sensitivity to hot is therefore an indication of an irreversible damage. Such teeth have to be treated by the Root Canal treatment to alleviate the symptoms of sensitivity.

We at Dr. Garg’s Multispecilaity Dental Clinic in New Delhi lay a lot of emphasis on educating patients on recognizing these early signs of tooth sensitivity and seek proper care before the situation becomes irreversible. Our dental experts through their experience and expertise diagnose and treat even the slightest cause of tooth sensitivity.
