Good night Girls, when did anyone start swelling gums?

Good night Girls, when did anyone start swelling gums? When did you first get your first tooth? My daughter is 3.5 months old, it's just awful, she puts her hands in her mouth, I take her hands away she freaks out again she pulls, she squeezes the pacifier then throws up, and again hands. And capricious became very. Do you think teeth already? Or too early yet?
