Please read this i am really scared.u

Ihad asked this question before but the image was missing now i am posting in the img as well.I am really really scared!! I have this lump on floor of mouth on the right sode.When i press it i feel like a bone underneath yhe skin or something hard. It is movable and painless.I went to a couple of dentists and they say it is a normal growth notjing to worry about.Can you please look into the picture and tell me if it is something serious :( One more thing i have a wisdom tooth erupting as well on the right side. but there is no pain in the tooth area but i do have pain/sore throat like thing on the right side of my throat. Is the swelling on the floor of mouth related to wisdom tooth? I am like your son who is really really scared i want to live a healthy life never drank or smoked till date just be truthfull and guide me through. may god bless u
