If your favorite foods cause tooth pain, it might be due to sensitive teeth. Sensitive teeth can limit your enjoyment of food. When the protective layer of your tooth (enamel or cementum) wears away, it exposes the dentin underneath, which has tiny tubules leading to the nerve. This can cause pain when eating hot, cold, sweet, or acidic foods. Several factors can cause this, including gum recession, grinding your teeth, and brushing too hard. To help with sensitivity, use toothpaste for sensitive teeth, avoid grinding by using a mouth guard, and brush gently with a soft-bristled toothbrush. If the pain is severe or lasts a long time, see your dentist. They may recommend treatments like fillings or protective coatings to reduce sensitivity.
