Canker Sores or Cold Sores

Canker sores and cold sores are lesions that anyone can have. The both have similar triggers but they are never the same. Most people use to get confused, not knowing the difference between the two. Your mouth sometimes shows how healthy your body is. When the strength of the immune system is low, most people do experience cold sore and canker sore at the same time.

It’s very important for you to know the the difference between canker sores and cold sores. Identifying these sores at their earliest stage can help to treat them effectively. Well, my purpose of writing this article is to show you some of their unique characteristics. I will also add some pictures to help you understand the symptoms better. Now, let’s look at canker sores first.

What are canker sores?

Canker sores also known as aphthous lesions or mouth ulcers, are small, painful ulcers that often appear in the soft tissues of the mouth, tongue and gums. These sores are very painful and can make eating, swallowing and talking uncomfortable.

The canker sores are divided into three main types, which includes:

1. Simple canker sores. These are canker sores that often develop three or four times a year. People between the ages of 10 to 20 years have more simple canker sores than other people. The symptoms are always minimal and the sores only last up to a week and heals on their own.

2. Complex canker sores. These types of canker sores are less common and usually comes with severe symptoms. People that have had simple canker sores before are more likely to have complex canker sores more often. These sores equally heals on their own, but they take a bit longer.

3. Herpetiform canker sores. These type of canker sores are not caused by virus, they usually develop later in life and are about the size of a pinpoint. Herpetiform canker sores often develop in clusters ranging from 10 to 100 sores at the same time. Sometimes the sores tend to all merge together.

Normally, canker sores heal on their own within one or two weeks. You should see your dentist or doctor as soon as possible if you have chronically occurring canker sores or if the sores are abnormally large and doesn’t seem to be healing on their own.

What causes canker sores?

The exact cause of canker sores is quite unknown. But there are certain triggers that are believed that they can contribute to recurring canker sores. Stress or minor tissue injuries in the mouth (caused by sharp tooth surface or dental appliance, aggressive teeth brushing, cheek bite, sports accident, etc) is thought to be the cause of simple canker sores. An allergic reaction to particular bacteria in your mouth and certain foods such as citrus or acidic fruits and vegetables can trigger a canker sore or make the problem worse.

In the other hand, complex canker sores are thought to be caused by an underlying health condition. People with impaired immune system, increased hormonal changes, nutritional deficiencies of vitamin B-12, zinc, folic acid, or iron, or with gastrointestinal tract disease, such as celiac disease or crohn’s disease are more likely to have complex canker sores more often.

Canker sores are not contagious at all. Unlike cold sores which typically appear outside the mouth (under the nose, around the lips, or under the chin), canker sores occurs only inside the mouth. Canker sore appear in circle or oval shape, being white or gray at the center, with a red edge or border.

What is cold sores?

Cold sores are small, painful blisters that typically occurs in clusters on or near the lips, on the nose, chin or anywhere around the mouth. These sores appear as tiny fluid-filled blisters and are sometimes called fever blisters.

Well, cold sores do cause lots of pain and discomforts. It is very common that about 8 out of 10 people have the virus that causes cold sores. Most people are first infected in their childhood even before they are 10 years old. At first, you might feel a tingling or burning sensation on your skin for about 24 – 48 hours before a cold sore appears.

What causes cold sores?

Cold sores also known as fever blisters are caused by herpes simplex virus type 1 (HSV-1). The herpes simplex virus (HSV-1) is closely related to the one that causes genital herpes (HSV-2). Both of these viruses are very contagious and can affect your mouth or genitals and can spread easily.

After your first infection, the virus remains dormant in the nerves of your face. The virus becomes active from time to time only when triggered, causing cold sores outbreaks. Although, you may not have any symptoms of cold sores, but once the HSV-1 virus is in your body, it can easily be transmitted to a healthy person. The virus responsible for cold sores can be transferred through the saliva (either directly through kissing, or by drinking from the same glass or cup) or by skin contact.

However, cold sores can never appear if the herpes simplex virus (HSV-1) is not triggered. There are certain factors that can cause these awakening and result to recurring outbreaks. Some of these common cold sore triggers includes:

  • stress
  • a viral infection or fever
  • fatigue
  • weakened immune system, especially during a sickness
  • exposure to harsh wind or sunlight
  • hormonal changes, especially during menstruation and pregnancy

However, HSV-1 can actually cause serious illness in people who have severely weakened immune system or other health problems like HIV/AIDS. Unfortunately, cold sores takes quite a long time to heal naturally on their own. Cold sores usually heal with or without treatments in two to four weeks without leaving a scar.

Symptoms of cold sores

After being exposed to cold sores triggers, many people tend to feel an itching, burning or tingling sensation around their lips or some areas around their face before a small, hard, painful blisters develops. As more days passes, more small fluid-filled blisters typically breaks out and cluster. The blisters may merge and then burst, leaving shallow open sores that will ooze fluid and then crust over.

Well, the symptoms and discomforts caused by cold sores vary, depending on whether it is your first outbreak or a recurrence. Recurrences often appear at the same spot each time and tend to be less severe than the first outbreak. (1) At the first outbreak, most people experience symptoms such as headache, sore throat, swollen lymph nodes, muscle aches or general body pain, fever, and painfully eroded gums.

Normally, cold sores heals within two to four weeks, but they often reappear when HSV-1 is reactivated later in life. They usually show up after a period of illness or stress, poor nutrition or sunlight exposure. Sometimes, dental procedures such as tooth extraction can actually stretch the oral tissues and trigger the virus. (2)

Cold sores treatment

Before treatments, your dentist or doctor will have to diagnose your cold sores by asking you about your medical history and also conduct some medical examinations. Some tests may be carried out to determine the underlying trigger or causes of your cold sores. From the results gotten from the tests, your dentist or doctor will determine a suitable treatment plan for you. Some of the common available treatment options for cold sores include:

  • Apply aloe vera gel: aloe vera gel is applied directly on cold sores to shorten the healing time and also reduce the discomforts. Naturally, the aloe vera gel contains powerful anti-inflammatory and antiseptic properties that makes them effective for treating cold sores.
  • Medications: there are suitable medications for cold sores. Although, this medications can never get rid of herpes simplex virus (HSV) but they help to shorten the healing process and also relieve pain and discomfort. Certain antiviral medications, acyclovir (Zovirax), famciclovir (Famvir) and valacyclovir (Valtrex) are often recommended.
  • Eat healthy foods: take enough healthy foods to boost your immune system. For instance, vitamin E aids the body with skin cell production and vitamin C can boost levels of white cells, which fight off viral infections. (3)
  • Be careful when handling cold sores. Try as much as possible to keep the area clean, you can apply suitable topical medications and gels. Also, do not pick at the crusts over the sores.
