Causes of Canker Sores in Kids
Medically termed aphthous ulcers, canker sores can be tied to a number of varying factors. However, the actual cause of canker sores remains a mystery. Vitamin deficiencies, food allergies, and even genetics all play a role.
Symptoms of Canker Sores in Kids
Canker sores can be easily diagnosed by your pediatrician, especially if the sore is recurring. Common symptoms include:
- Small, painful blisters in and around the mouth
- White or yellowish coating with a red outline
- May appear in small clusters
Treating Canker Sores in Kids
If your child experiences canker sores more than two or three times a year with severe pain associated with an outbreak, see your pediatrician for treatment right away.
For less severe cases of canker sores there are a few things you can do, if approved by your child’s doctor:
- Lessen the pain with an over-the-counter pain reliever
- Avoid abrasive foods that can irritate the gums, cheeks, and tongue
- Keep away from foods your child is allergic to
- Avoid spicy, overly salty, and acidic foods
- Gently brush with a soft-bristled toothbrush
- Encourage daily brushing and flossing to limit infection
- Swap out your kids’ toothpaste for a gentler formula with a mild flavor
- Rinse with an alcohol-free mouthwash to remove bacteria and aid healing
