What causes “mouth blisters”?


I assume I’m not the only person this happens to...
Every so often, I will develop a painless blister on the inside of my cheek, typically up above the gumline. If I pop it, it is filled with some clear, salty fluid, and does not re-occur. These blisters seem to develop very rapidly, within seconds.

What are they, and what causes them?

Not all blisters are the same (or have the same cause).

Need more info (things you ate recently, allergies, etc.).

Also, this is a really bad place to get medical advice. Call your doctor (really).

I’ve had these for 50 years. I don’t think I need to get a doctor involved, LOL.

Could be Sodium Lauryl Sulfate (SLS) in your toothpaste. It serves no real purpose other than making your toothpaste look more sudsy.

It causes all sort of mild mouth sores.

Try Biotene or other SLS free tooth paste

A tiny salivary gland gets blocked. They're the many things that feel like tiny bumps under your cheek gums. I forgot the technical term of the condition. Occasionally the bubble has to be removed by the dentist in order not to keep reoccurring, but usually they stay gone. Had to do this with my daughter when she was young.

You've had blisters in your mouth for 50 years and have never asked a doctor about it?

You are only now asking the SDMB?

That "LOL" seems more on you than anyone.

You really need to work on your reading comprehension...
I never said I had them all the time, I said "Every so often...”

needscoffee probably has the right answer.

The lil'wrekker gets them during seasonal allergy times. She has a mouth full right now.

She also gets peri-oral bumps and fever blisters. I think some folks are just prone to this kinda thing.
We've talked to many Doctors and Dentists about it. No one has answers.

I've had these from time to time. I've never called them "blisters", although I suppose they look a bit like blisters. I have called them "cysts", because I think that's what they are, tiny harmless cysts. I usually poke at them with my tongue until the blockage loosens up and they disappear. I have popped them once or twice, I think.

Really?

You said:

- "Every so often, I will develop a painless blister on the inside of my cheek, typically up above the gumline."

- "I’ve had these for 50 years."

What did I miss? Why would you not mention this to a doctor or dentist (also a doctor) in 50 years?

I never bothered to ask a dentist about them, either. I was a little alarmed the first time it happened, but after worrying the bump away, I realized what the mechanism was, and
it didn't seem very scary. I don't get them often. I suppose if I had them all the time, or they interfered with anything, I might ask a dentist about them.

While asking the SDMB is fine I would suggest that anyone, with any medical problem they are concerned about, is best served by asking an appropriate medical professional.

YMMV

(My caveat to this would be for more minor things...like how to best take the sting out of a minor burn ...that kind of thing.)

Is this a minor thing? Sounds not great but I dunno...

It's called a mucocele. Very common.

Not sure about cheeks, but my daughter used to get them on her tongue. First we thought it was because of her braces but then the dentist referred us to an oral health specialist. She basically said it was normal and used a Silver Nitrate stick on the blister and it brought immediate relief to my daughter.

I asked her to write me a prescription for silver nitrate sticks but she said “it was to be used only by trained medical professionals “ and is not available at pharmacies. She told me to make an appointment every time she needed an application of the AgNO3 sticks.

Came home, went to the internet and bought the sticks from a reputed pharmacy (no prescription was needed). Had to use it half a dozen times and then she never got it again for many years now.

Dentist here, sounds correct to me. As you stated in your other post an accessory salivary gland gets pinched and swells. Usually drain on their own or when you bite them. Another very common area to get them is the lower lip.

Well, I was alarmed the first time it happened, 40 years ago. I have not been concerned with them for 40 years.
