A tongue spasm is an example of a focal dystonia, which is an involuntary and sometimes painful movement of muscles in the body -- in this case, the muscles in the tongue. Tongue spasms can be serious if they make talking and swallowing difficult and uncomfortable.

Depending on the cause of your tongue spasm, the condition can be serious. In some cases, tongue spasm may be caused by a more serious underlying disorder. See your doctor if you have tongue spasm.
