How do we feel the tactile sensations when we touch our teeth

The same way you feel tactile sensations when you tap a bicycle helmet on you head: the motion (or vibration) is transferred through the material to your head & the nerve endings in your scalp the same as tapping a tooth sends vibrations to the nerves in & at the base of the tooth.
