Tingling in the tongue can be the result of an infection, vitamin or mineral deficiency, poor dental hygiene, and possibly even a stroke. Sufferers should seek immediate medical care if a sudden onset of tingling occurs, states Healthgrades.
Tingling in the tongue includes a prickly, burning feeling likened to a pins-and-needles sensation. In some cases, it accompanies numbness or the inability to feel pressure, taste or texture on the tongue. Mild cases of tingling tongue may result from bacterial growths. However, severe cases can indicate serious medical issues, and those experiencing such cases should see a doctor as soon as possible, advises Healthgrades.
