Mouth Sores or Spots

What are Mouth Sores?

Mouth sores can cause significant discomfort and pain, particularly in children. They can be caused by various factors such as viruses, injury, stress, and medication. These sores appear as white, red, or pink and can result in swelling, irritability, and sometimes even a fever or headache. They are often harmless, but severe or persistent cases may require medical attention.

Is it a Canker or Cold sore?

Mouth sores can be a source of discomfort and pain, but are usually benign. They are referred to as “canker sores” when they appear inside the mouth, while “cold sores” are caused by the herpes virus and occur on the lips. Both types of sores will eventually go away on their own. If your child frequently gets canker sores in the same spot, it may be due to a sharp tooth in the area. Let us know at your next visit, as we may be able to smooth out the tooth to prevent further sores.

How Can I Help My Child with Sores?

A parent can help their child with mouth sores by providing them with over the counter pain medications. This can be done by offering soft foods, avoiding acidic or spicy foods, and applying a numbing gel or ointment. Popsicles may even be offered.

Are Mouth Sores Contagious?

Not all mouth sores are contagious. Your pediatrician can determine the type of sore your child has and if it can be spread to others.

If your child has a mouth sore that won’t go away, it’s important to monitor for any signs of infection or other serious illness, such as trouble swallowing, fever, or dehydration. If you notice any of these symptoms, seek medical help immediately. Remember, any sore that persists for more than 14 days should also prompt a call to your family doctor.
