Elmex sensitive professional toothpaste sensitive teeth 75 ml

When the gum retracts, the part of the tooth not protected by the enamel remains exposed. This involves exposing the dentin with thousands of microscopic canals (tubules) connected to the nerve endings.

When the teeth are exposed to air or to hot, cold or sweet food, these stimuli are transmitted through the channels directly to the nerve endings of the tooth causing the sensation of pain and sensitivity.
