Thanks for writing in.
sores are also known as aphthous ulcers
. While their exact cause is not known, stress
, poor nutrition, food allergies
can increase the chances of having them.
Also, while they will heal on their own in 7-10 days, the pain can be relieved using Motrin
. If there is no relief, please see your physician .
Brushing after every meal, using a soft floss, and avoiding chewing gum, and hard, crunchy or spicy foods may help prevent them.
It is possible that your son has a worm infestation which is leading to the pain after eating. This can also lead to poor nutrition which increases his chances of getting canker sores. Please get a stool examination done to rule out intestinal worms after consulting his physician.
Hope this helps.
