Short Description
A hard, yellowish layer beneath enamel that makes up most of the tooth and contains microscopic tubules leading to the nerve.
Long Description
Dentin is the dense, calcified tissue that forms the majority of a tooth’s structure, located beneath the enamel and surrounding the pulp chamber. Unlike enamel, which is highly mineralized and protective, dentin is more porous and sensitive, containing tiny tubules that connect to the nerve inside the tooth.
Because dentin is softer than enamel, it is more susceptible to decay and erosion once exposed due to enamel wear, cavities, or gum recession. When exposed, dentin can cause tooth sensitivity to temperature changes and certain foods, leading to discomfort.
Preventing dentin exposure involves maintaining strong enamel through proper oral hygiene, fluoride treatments, and avoiding acidic or abrasive substances. If dentin becomes compromised, treatments such as bonding, fillings, or crowns can help protect and restore the tooth.
