Anyone know if I should be feeling sensitivity to gum only on outer side wherei had a tooth extracted. Used flap method. That flap side is where. Hard cookies feel like knife blades. Hot liquid gets a reaction. Seems like i have more nerve endings then most ppl. The area that ks pale white has no feeling. But the reddish pink skin tissue is where i get sensitive. It has been around 4 months since it happened. can anyone relate?
