Asking because I was eating ice cream 13 minutes ago and this happened.
In: Biology
It’s not just from eating something cold; it’s specifically from getting the *roof of your mouth* cold quickly.
There are a lot of important blood vessels and nerves that pass through that region (it’s all close to the face and brain). When you rapidly cool it, the blood vessels and nerves get rapidly squeezed and then expanded again as they warm up. This puts pressure on the blood vessels and nerves, which the body interprets as pain.
