Tooth sensitivity after freezing gums with Coke

hey guys,

Snorted some coke last week .. froze my gums with the leftovers (apologies if my jargon may be a lil off .. basically put some of it over my gums)
After awhile i noticed one of my front tooths had gone numb .. didnt give it too much thought but since then that particular tooth has been quite sensitive to any liquids i take.

Im hoping this is temporary. Anyone else have a similar experience nd could share what i could do to get rid of the issue?

All help much appreciated.
