Yes, warts can spread if you put your finger with a wart in your mouth. Warts are caused by the human papillomavirus (HPV), which can be transmitted through direct contact. If the virus comes into contact with mucous membranes in the mouth, it may lead to the development of warts in that area. It's best to avoid touching warts and to practice good hygiene to prevent spreading the virus.
