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

• 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

• 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

• 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

• 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.
