Tooth sensitivity

Tooth sensitivity, medically termed as "dentin hypersensitivity", is a sharp and sudden pain in the teeth when exposed to certain stimuli such as cold, heat, sweet, or acidic foods and drinks. It can be a temporary or chronic condition affecting one or more teeth.

History[edit | edit source]

The phenomenon of tooth sensitivity has been documented for centuries. Ancient texts make mention of dental pain upon consumption of hot or cold substances.
Over the past few decades, research has deepened our understanding of the causes and treatments for this condition.

Causes[edit | edit source]

Dental erosion: Wearing away of the enamel due to acidic foods, drinks or stomach acid.
Gum recession: Exposes the sensitive root surface.
Tooth grinding: Can wear down enamel.
Tooth decay: Cavities can expose the inner layers of the tooth.
Dental procedures: Sensitivity can occur temporarily after fillings, crowns, or teeth cleaning.

Treatment and Prevention[edit | edit source]

Desensitizing Toothpaste: Contains compounds that help block sensation from the tooth surface to the nerve.
Fluoride Gel: Applied by dentists to strengthen tooth enamel.
Dental Sealants: A protective coating applied to the exposed root surfaces.
Root Canal: In severe cases where sensitivity is caused by nerve damage.
Preventative measures include using a soft-bristled toothbrush, avoiding acidic foods and beverages, and regular dental check-ups.

Myths and Misconceptions[edit | edit source]

Many people believe that sensitive teeth mean they have cavities. However, while cavities can cause sensitivity, not all sensitivity is due to decay.
Some think that brushing harder will help, but it can actually exacerbate the issue by further wearing away the enamel.
