They are tricky to get rid of... If she can tolerate it she needs to rinse her mouth with peroxide and let it bubble a minute or so, also rinsing with warm salt water will help. Table salt will burn so use sea salt or non iodized salt. Try to avoid milk and milk products the will sit and sour on the sores and make them worse.
My Two Year Old Daughter Has Ulcers On Her Tongue She Has Had Them On And Off For About Seven Weeks Since Having A Viral Infection.the Ulcers Are Not Yellow Or Puss Like ,they Are Like Craters With Red Edges They Clear Up But Are Back In A Few Days. Can You Help?
Does she happen to like cinnamon-flavored candy (ie red hots, hot tamales, big red gum?) I know those--still to this day--do that to my tongue. It took a long time to figure out the correlation. I avoid those and no more sore tongue! My doctor when I was younger told my mom just to alternate ibuprofen and acetaminophen with me until they went away. Warm water swishes will help the ulcers to heal.
