Teeth are normally covered by a layer of super hard tooth enamel, which completely isolates the core of the tooth (nerves, blood vessels) from the outside. When this outer layer of enamel is damaged, e.g. through tooth decay, excessive wear, cracks etc. a pathway to the nerve inside the tooth is created which can provoke sensitivity to hot or cold, sweet or sour. Sometimes, receding gums can expose the roots of teeth with much the same effect, as tooth roots do not have a protective enamel cover. Obviously, tooth decay or cracks should be addressed promptly by a dental professional, but there is no “easy fix” for exposed roots. You dentist may recommend a product that seals off the roots and prevents sensitivity. We have a selection of products in this category that may help in providing relief for tooth sensitivity.
