What Causes Tooth Sensitivity?

Brushing too hard: Using excessive force or a hard-bristled toothbrush can wear down enamel and cause gum recession, leading to sensitivity.
Gum recession: Exposed tooth roots due to receding gums can make teeth more sensitive.
Gum disease: Inflammation and infection of the gums can expose tooth roots and cause sensitivity.
Cracked teeth: Cracks in teeth can allow bacteria to enter and cause inflammation or infection.
Teeth grinding: This habit can wear down enamel and expose the underlying dentin, causing sensitivity.
Teeth whitening products: These can irritate the teeth and gums, leading to sensitivity.
Acidic foods: Frequent consumption of acidic foods can erode enamel, leading to sensitivity.
Recent dental procedures: Sensitivity after dental work is usually temporary.
