OP, I have this issue because I brush my teeth too hard and often. I am a bit obsessive, easily a 4 times a day-er or more. Get a soft toothbrush, brush in circles, and try to go easy on your gums.

The bad news is that it is not fixable. All you can do it prevent more damage.

Definitely get it checked out so you don't end up getting cavities in the teeth where the roots are exposed. I had that happen due to brushing too hard and have had gum surgery as well. You don't want to end up going down that road, it's painful and expensive.

I had gum issues post-partum. Get it checked out, but remember that the hormonal stuff does make one's gums weird.

Do you brush your teeth very aggressively and/or the wrong direction? My sister did and this caused her gums to recede. She had to have a surgery to graft some skin from the roof of her month to the gum area -- and she said it was excrutiatingly painful.

Do you grind your teeth at night?

OP here. I had a baby 4 months ago. This gum thing seems to have appeared overnight.

It's so gross. I keep flicking it with my tongue.

isn't this gingivitis?

You just had a baby?! That's probably the reason! Pregnancy causes all sorts of weird dental/oral problems. I went to the dentist while pregnant and my gums bled like crazy. I hardly flossed for 9 months.

Although I don't know about post partum.

Talk to your dentist.

Pregnancy may have caused something to happen.

No medications. Not dehydrated. Just went back to work from maternity leave last week and have been drinking a lot of soda there. Could that cause it? That fast?

You should give "oil pulling" a try. Google it.

Do you drink a lot of soda? Or does gum disease run in your family?

Are you on any medications? Dehydrated?

Just noticed this - so gross. In between two of my bottom front teeth the gums have detached from the teeth and they look "looser" elsewhere in my mouth. Has anyone had this happen?
