Swelling of the tongue is a very unpleasant health problem; it hinders breathing and swallows food.

The oral and dental surgeon, Professor Peter Jurin, said the swelling of the tongue was caused by a fluid accumulation in the tissue, noting that it was usually accompanied by redness and a white layer with pain and numbness.

He added that swelling of the tongue has several reasons, most notably burning due to eating foods or drinks too hot or infections such as gingivitis or allergic responses to certain foods. Swelling may also be due to certain medications, such as blood pressure medications.

In any case, you should consult your doctor to determine the true cause of swelling and treatment of the tongue.
In general, the German professor emphasized the importance of regular hygiene of the tongue to remove the white layer accumulated by the abrasive tongue or toothbrush with soft bristles.
