If your child has ever said “that hurts my teeth” during mealtime or toothbrushing, keep reading — we’re here to break it down for you!
What Is Tooth Sensitivity in Kids?
Tooth sensitivity, or “dentin hypersensitivity,” happens when the protective enamel on your child’s teeth becomes worn or thin, exposing the sensitive layer underneath. This makes hot, cold, sweet, or even acidic foods and drinks feel uncomfortable or painful.
Common Signs of Tooth Sensitivity in Children
Complaining of pain when eating ice cream, popsicles, or hot soup
Avoiding cold or sweet foods
Discomfort while brushing or flossing
Sudden sensitivity to air or water
Wincing or pulling away during dental cleanings
If these signs sound familiar, it may be time to visit your trusted kids dentist in Sedona, AZ.
What Causes Tooth Sensitivity in Kids?
There are several reasons why children may develop sensitive teeth:
1. Enamel Erosion
This can be caused by acidic foods or drinks, teeth grinding, or even brushing too hard.
2. Tooth Decay or Cavities
Small holes or damage in the enamel can expose the sensitive parts of the tooth.
3. Gum Recession
Less common in younger kids, but possible in children with gum inflammation or early-stage gum disease.
4. Newly Erupting Teeth
As new permanent teeth come in, some kids experience temporary sensitivity.
5. Cracked or Chipped Teeth
Even small cracks can expose nerve endings and cause pain.
