Why Are My Teeth Suddenly Sensitive? Common Causes and What to Do

Sudden tooth sensitivity can be alarming, especially if you’ve never experienced it before. If you feel a sharp pain when eating something hot, cold, sweet, or acidic, your teeth may be reacting to exposed dentin—the layer beneath your enamel.

Common causes of sudden sensitivity include:

• Tooth decay or cavities
• Gum recession exposing the tooth roots
• Worn enamel from brushing too hard or acidic foods
• Cracked teeth or recent dental work
• Teeth grinding (bruxism)
• Whitening products or acidic mouthwash

In many cases, sensitivity is temporary and treatable. Using a sensitivity toothpaste, avoiding acidic foods, and switching to a soft-bristled toothbrush can help. However, if the pain persists, it’s important to visit your dentist to rule out more serious issues like infections or cracks.

At Alpine Dental, we offer thorough evaluations to identify the exact cause of your tooth sensitivity and provide gentle, effective treatments to restore comfort and protect your smile.
