What could be causing my lips and tongue to feel numb and tingle?

A numb feeling and tingling in the lips and tongue could have several possible causes:

  • You might be getting a canker sore (aphthous stomatitis). These small, shallow sores on the inside of the lips or under the tongue often cause a tingling sensation a day or two before they appear.
  • You might have dry mouth (xerostomia). A common symptom of dry mouth is a tingling sensation in the tongue. Dry mouth can be caused by certain illnesses and some medications. Talk to your doctor if you are concerned about dry mouth symptoms.
  • Numbness and tingling in the lips and tongue can sometimes be a side effect of a drug. Call your doctor if you experience these symptoms while taking medication.
  • Itchiness and tingling in the lips and tongue are common symptoms of a food allergy. If you think you might have a food allergy, talk to your doctor about testing.
  • People with diabetes can get numbness and tingling in the lips and tongue if their blood sugar drops too low (hypoglycemia).                                                                         

If you're experience numbness and tingling in your lips and/or tongue, it is always best to see a doctor for a check up.
