How Aging Affects Our Mouth

© getmouthpower.org

Aging is a normal life process, which is subtle and is characterized by individual variation in onset and rate of decline. The basis of this process lies in changes in various macromolecules (from D.N.A. to membrane proteins) which primarily lead to alteration the form of function of a tissue or organ as a result of biological activity associated with a minor disturbance of normal cellular turnover.

Causes of Sensitive Teeth

Are you suffering from sensitive teeth?

Tooth sensitivity or known as dentin hypersensitivity is short or transient sharp pain of a rapid onset that arises from exposed dentin layer of one or more teeth subsequent to loss of tooth structure (enamel layer of the crown or cementum layer of the root). It usually occurs in response to stimuli—typically cold, air pressure, drying, sugar, acids, chemicals or forces acting onto the tooth—and cannot be ascribed to any other dental defects or pathology. These stimuli are non-noxious, and are not generally expected to generate a pain response, except as seen in sensitive teeth. In contrast, a noxious stimulus would be the toxins of bacteria within a decay lesion leading to dentinal pain. Areas of exposed dentin at the junction between the crown and the root (cervical area) account for much of the observed tooth sensitivity. Continue reading

What causes sudden tooth sensitivity

Tooth sensitivity is defined as an experience of pain or discomfort that is sharp, sudden, piercing or excruciating in nature that is felt deep into the nerve endings. The pain may affect the tooth constantly or intermittently depending on its cause and nature.

Generally tooth sensitivity is caused by receding gums and enamel damage that leads to dentinal tubules in the dentine layer to be exposed and hence sensitized. Therefore, thermal sensitization like hot or cold drinks intake may make you cringe in agony. Occasionally, sweet and sour foods or even breezy cold air could also inflict sudden sensitiveness.

Factors that leads to dentine exposure: Continue reading
