Whenever a baby is in distress, it leaves the whole house in pain. Similar is the scenario when the suffering is because of those irritating mouth ulcers. Generally, they are not so common in newborns, though there are many factors that can induce an ulcer in their mouth.

What are Mouth Ulcers/ Canker Sores?

  1. These are open wounds that spread across the mouth lining. Varying in size, they could appear singly or in a group. They may develop in gums, cheeks, lips or tongue.
  2. Canker sores are little different from ulcers as they mainly appear in soft tissues and are not contagious.
  3. Cold sores are mainly caused by a virus Called Herpes virus in toddlers and appear outside the mouth. Being a viral sore, it is highly contagious and easily spreads.

Causes of Mouth Ulcers

Why do the mouth ulcers develop in infants? They are normally not a sign of disease or illness in infants, however many other reasons can advance to ulcers in tiny toons.

  1. It could be a Canker sore if it is a viral infection. But this is common in kids above 5 years of age.
  2. A burn with hot food, biting the tongue or cheek, eating sour food like pineapples can lead to an ulcer.
  3. Low immunity levels in your infant can trigger the formation of white spots in their mouths.
  4. Some elders relate a mouth ulcer presence to an upset stomach. Acidity, indigestion or abnormal stool could be the reason.
  5. Many times, forceful brushing or wiping gums with finger cloth can hurt the soft tissues, creating mouth injuries.
  6. Stress does affect mouth ulcers. Of course, that playful toddler can feel anxious and stressed out in her routine and develop the itchy sores in the mouth.
