Mouth Ulcers in Babies: Causes and Treatment


About 1 in 5 individuals routinely get bothersome canker sores, which can make eating, drinking, and even brushing teeth a real pain. But just since they’re relatively typical doesn’t mean these little open sores inside the mouth should be neglected.

About Canker Sores

Likewise referred to as aphthous ulcers, canker sores are small sores that can occur inside the cheeks and lips, at the base of the gums, and on or under the tongue.

But don’t puzzle canker sores with cold sores or fever blisters, which are sores brought on by the herpes simplex virus and found outside the mouth around the lips, on the cheeks or chin, or inside the nostrils. Whereas cold sores are contagious, canker sores are not contagious– so kissing can not spread them.

  • Although canker sores aren’t contagious, the propensity to have outbreaks of canker sores can run in a family. No one understands exactly what causes canker sores, however many elements are believed to put a person at risk. Diet may play a part. Individuals who have dietary deficiencies of folic acid, vitamin B12, and iron appear to develop canker sores more often, as do those who have food allergic reactions. Canker sores also can show an immune system issue.

Mouth injuries, such as biting the inside of the lip or perhaps brushing too hard and harmful the delicate lining inside the mouth, also seem to cause canker sores. Salt lauryl sulfate (SLS), an active ingredient in many toothpastes and mouthwashes, has actually been connected to canker sores and is believed to extend the healing time of the sores.

Even emotional stress could be a factor. One research study of college students showed that they had more canker sores during demanding periods, such as around examination time, than they did during less difficult times, such as summer season break.

Although anyone can get them, youths in their teenagers and early twenties appear to get them usually, and women are twice as most likely to establish them as men. Some ladies and women find that they get canker sores at the start of their menstrual durations.

Signs and Symptoms

Canker sores typically look like round, painful open sores that have a white or yellowish coating and a red “halo” around them. They tend to be little ( 1/4 inch, or 6 millimeters throughout) and shallow, but occasionally they may be larger and deeper. Frequently, canker sores appear alone, but can also appear in small clusters. Often an area will tingle or burn before a canker sore in fact develops.

Canker sores normally are not accompanied by other symptoms (like fever or swollen lymph nodes). If they are, this could be a sign of another condition that need to be checked out.

It takes about 2 weeks for canker sores to recover. During this time, the sores can be painful, although the first 3 to 4 days are normally the worst. Unless they are very large or deep, they typically heal without scarring.

If your child establishes canker sores that last longer than 2 weeks or is not able to eat or drink since of the pain, call your doctor. Likewise call the doctor if the sores appear more than two or 3 times a year.


Tests are normally refrained from doing to identify canker sores, as a doctor can determine them based on case history and physical exam alone.

If your child has really frequent or severe bouts of persistent canker sores, the doctor might wish to carry out tests to search for possible nutritional deficiencies (which can be corrected with dietary changes or using prescription vitamin supplements), body immune system shortages, and food or other allergies.


The majority of canker sores will recover on their own in a couple of days to a couple of weeks. If your child suffers pain during this time, offer over the counter painkiller like ibuprofen or acetaminophen.

If a sore does not get better after a few weeks or keeps coming back, see a doctor or dental professional. He or she may prescribe a topical medication, special mouthwash, or home treatment to help heal the sores.

For medicines that are used straight to the sore, first blot the area dry with a tissue. Use a cotton bud to apply a percentage of the medication, and make sure your child doesn’t eat or drink for at least Thirty Minutes to make sure that the medicine is not gotten rid of.

Caring for Your Child

Help make canker sores less painful and avoid them from recurring by encouraging your child to:

  • prevent consuming abrasive foods, such as potato chips and nuts, which can aggravate gums and other delicate mouth tissues
  • attempt brushing and rinsing with tooth pastes and mouthwashes that do not consist of SLS
  • use only soft-bristle tooth brushes and be careful not to brush too hard
  • avoid any foods she or he is allergic to
  • prevent spicy, salty, and acidic foods (such as lemons and tomatoes), which can aggravate tender mouth sores

Although they can definitely be a pain, in many cases, canker sores aren’t a huge problem. Many individuals have learnt how to deal with them– and your child can, too.
