|HOME CARE ADVICE FOR CANKER SORES (HARMLESS MOUTH ULCERS)|
- Canker sores are the #1 cause of mouth ulcers:
- 1 to 3 painful, white ulcers of the inner cheeks or gums (no fever).
- Causes include injuries from rough food, tooth brushes, biting, food irritants, etc.
- Liquid Antacid for Pain Relief: Â
- Use a liquid antacid 4 times per day for pain relief. (Some parents prefer regular mouth washes, but they may sting).Â
- Children over age 4 can use 1 teaspoon as a mouth wash after meals
- For younger children, put Â½ teaspoon in the front of the mouth after meals.
- Pain Medicine: Give acetaminophen (e.g., Tylenol) or ibuprofen for severe pain (especially at bedtime).
- Fluids : Â
- Offer a soft diet. Â
- Encourage favorite fluids to prevent dehydration. Cold drinks, milkshakes, and popsicles are especially good. Â
- Avoid salty foods, citrus fruits and foods that need much chewing. Â
- For infants, give fluids by cup, spoon or syringe rather than a bottle (Reason: The nipple can cause pain).
- Contagiousness: Canker sores are not contagious. Children with fever or many mouth ulcers need to be examined before returning to day care or school.
- Expected Course: They heal up in 1 to 2 weeks. Once they occur, no treatment can shorten the course, but treatment can reduce the amount of pain.
- Call Your Doctor If:
- Mouth ulcers last over 2 weeks
- Your child becomes worse
And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
