Sensitive Teeth (Not Gums) in early pregnancy?

[~Adorkable~]

so the last 4 days or so my teeth have been really sensitive, they almost feel like i have been grinding them (which i have never had an issue with, having way way to much citrus or that i have been bleaching them too much (experienced that feeling 15 years ago when i got my braces off)
my gums are fine

anyone ever had this issue and/or had it explained to them?

totally. too cold is the worst! i think all my nerves are more sensitive and my teeth haven't been spared.
