• Enamel erosion: Over time, acids in meals and drinks can break down and put on away tooth enamel, inflicting signs.
• Enamel abfraction: Enamel abfraction is injury resulting from bodily or mechanical pressure. It will possibly trigger seen grooves within the enamel.
• Gum recession: Growing older, genetics, and advanced gum disease trigger gum tissue to recede, exposing dentin and tooth roots, resulting in tooth sensitivity.
• Worn restorations: Dental fillings, crowns, and restorations may grow to be broken or worn over time, exposing dentin and elevating the danger of tooth decay.
• Tooth fracture: Fractures (breaks), cracks, or chips in tooth enamel may expose dentin, permitting warmth, chilly, or different triggers to achieve the dentin.
• Current dental therapies: The nerves within the root of enamel can grow to be infected after dental fillings, crowns, or restorations. This could resolve inside 4-6 weeks.
