I had the same issue growing up. I would get sores -- huge ones -- all the time. They seemed to get worse with stress. Strangest thing: they stopped entirely when I was pregnant with my first kid and never came back.

Probiotics go to Whole Foods and get one they recommend and use often.

Start by changing toothpaste brands, if you haven't already, and take to pedatrician.

My DD did. It was one of the first signs of Juvenile Arthritits, later dxed as Bechet. It would be about 7 years until other symptoms in entirety resulted in a dx, otherwise I would have just thought it was normal to a degree.

This was me too.

+1 me too

But I had them mid childhood (age 9-12 or so?) for a few years and they just stopped after awhile. FWIW i have never had any health problems. Was a mystery.

get a blood test for celiac disease

My kid gets a sore in her mouth every now and again, looks like a white head pimple but in her mouth. I get cold sores as an adult and remember getting these when I was younger so think it’s how it starts

It is likely something more than 50% of the population has. And yes, related to cold sores.

Just like roughly half those reasons this, she is infected with herpes simplex. No, the prevalence of herpes simplex in the general population has nothing to do with sex. Do t go there.

It is far more common than people admit, and no one wants to face the science, but yeah - it’s probably a recurring herpes infection. There is no cure but there are antiviral treatments it it’s bad.

Ask a doctor.

Strawberries, cashews, and sls containing toothpaste all trigger them for me.

I don’t understand why you’d wait until the well child to ask the doctor about something that is bothering her? Because you think the doctor won’t be able to do anything to help?

Go to dentist or doctor hopefully with sores. Could be herpes. Could be the steroid inhaler. BTW she should rinse mouth thoroughly, gargle, rinse again right after the steroid. Thrush. Nasty.

I had them often as a child, but outgrew them. Dabbing with a Q-tip dipped in hydrogen peroxide helped them heal faster (stings for a second, but not awful).

B complex helps the sores dissappear really quickly !!

Zinc is supposed to help

Same here. My DD started getting many canker sores at a time and tested positive for Celiac Disease. If she is exposed to gluten, the sores return.
