How can i tell if its my jawbone i feel or a wisdom tooth?

I have no pain or gum swelling back their and dont have dental insurance or enough money right now. So any. its smooth so im gunna say jawbone. What do you think
--------------------
you cannot feel the tooth unless its below the gums and outside the bone. you will feel the sharp edges and blanching (whiteness) in the gums if the tooth is there. if the area is smooth then its jaw bone.
