Question: canker sores


 joyce813 - Fri Dec 10, 2004 8:19 pm

My 3 year old had 2 canker sores in his mouth that lasted a week. He got 2 more as soon as the first ones went away? What could cause this?

User avatar Hello:
I am sorry you little one has had to deal with this. Here is some information about canker sores you might find helpful.

Canker sores are small, round, open sores inside your mouth.
The center of the canker sore can be white or yellow.
They can be painful.
They are not harmful.
We do not know what causes canker sores.
There are things that may trigger them:
Stress
Not getting enough iron or vitamin B12
Food allergies
Fatigue
Biting your cheek or tongue
Anyone can get canker sores.
Teens and young adults get them more often.
Women also get them more than men do.
Canker sores can run in families.
The first sign can be a tingling feeling in your child's mouth.
A sore that looks like a small, round, red spot or bump will form.
It will then turn into an open canker sore. The center of the canker sore can look white or yellow
It is usually small.
They can be painful
Canker sores are not contagious.
Most canker sores heal by themselves.
There is no treatment that will stop canker sores from coming back. You can do some things to lessen the pain.
Homemade mouthwashes. Swish the mouthwash in your mouth for one minute and spit it out. Do not swallow. Do not use for children who cannot spit it out (usually children less than 7 years).
Mouthwash #1: 2 ounces of hydrogen peroxide + 2 ounces of water
Mouthwash #2: 4 ounces of water + 1 teaspoon of salt + 1 teaspoon of baking soda
The doctor may give your child a prescription drug.
Do not eat spicy foods or acidic foods such as lemons or tomatoes.
Do not eat sharp foods like potato chips. They can poke the canker sore.
Carefully brush your teeth so you don't poke the canker sore.
Canker sores can last for 2 weeks.
The pain is usually gone in 3 to 4 days.
Canker sores cannot be prevented.
Call your doctor if your child's canker sore does not go away.
Call your doctor if your child's canker sore gets worse.
Call your doctor if your child also gets a fever, diarrhea, headache, or skin rash
Call your doctor if you have any questions about your child's condition.
I hope you little one feels better soon,
Carolyn

I was wondering if there is a home remedy for canker sores in the throat. Thank you :cry:

I have been having cankor sores in my mouth and tongue now for 3 months. They go away but they come back but not in the same spots. Very painful. I am 69 yrs old I have dentures and am unable to wear my dentures most of the time. My dr has tried everything and we are now going thru allergy tests. The last will be done next Thursday. So far no food allergys, which I was hoping it was. They have done blood tests and so far nothing. I have tried mouth washes, (home remedies), perscriptions and nothing is working. Any suggestions??????? Please help me.
