If worms come out from mounth wht best need to done ?

Seek Medical Care: Would recommend medical evaluation to determine type of worm and degree of infestation. From there a treatment plan can be developed. Good luck.

See a doctor: The only worms likely to be seen with the naked eye coming out of the mouth are ascaris lumbricoides, and you would generally need to be very heavily infected. See an infectious diseases expert and have the worm with you or bring a stool specimen along.
