Causes for Sensitive Teeth to Cold or Hot Temperatures

Do your teeth have a painful reaction to temperature or pressure – whether it be from cold food or flossing your teeth? If so, some possible causes for this reaction include:

  • Cavities
  • Fractured or split teeth
  • Worn fillings or enamel erosion
  • Periodontal disease
  • Exposed tooth root

But don’t panic — Tooth sensitivity is a very common condition and is treatable! The first step to take is making an appointment with your dentist for an evaluation. Your dentist will find the cause of the problem and give you your next step to treating your pain and sensitivity.
There are a variety of treatments (in-office or at home) depending on the cause of the sensitivity, so your dentist might suggest:

    • Diet change – acidic foods harm your teeth
    • Mouth guard – if you grind your teeth, you might need this to protect your teeth
    • Softer toothbrush – brushing your teeth too hard can damage your tooth’s surface
    • Desensitizing agents – helps with nerve pain by blocking the sensitivity
    • Fluoride gel – strengthens tooth enamel with a protective coating over your teeth
    • A crown, inlay or bonding – might be needed if the tooth is worn or damaged
    • Surgical gum graft – in more serious cases, this surgery will protect exposed roots
    • Root canal – this choice is usually suggested if the pain isn’t treatable by any other options


Proper oral hygiene and regular dental checkups are the most important way to prevent having sensitive teeth. Ask your dentist today about any concerns with tooth sensitivity.
