Tooth sensitivity is a feeling of pain when something touches the teeth. This can occur due to:
Metals: Root canal fillings, crowns, braces, and dental implants. - Bacteria: Cavities on the tooth or in the gum line
Acidic Foods: Sugars or acidic foods such as lemons and oranges. - Friction: When it rubs against your teeth, like chewing food or brushing too hard.
