Frequency of oral herpes

Herpes on the tongue is quite common nowadays, which makes it even more important to learn about prevention and treatment for the sake of your oral health. The infection can lead to anything from subtle irritation to blistering sores. Since the virus can be easily transmitted through skin-to-skin or oral contact, there is a large segment of the world population that is infected with this condition. Here’s a study from World Health Organization conducted in 2012 that estimates about 3.7 billion people under the age of 50 to be suffering from this chronic infection.

Oral Herpes can occur in different ways

There is more than one place where you can have oral herpes. You can have:

  • Herpes of the throat
  • Herpes on the gums
  • Herpes on the roof of the mouth

For some people, symptoms may even appear on the upper lip, on or inside the nose, or on the cheek or chin. All variations of this disease can be exceptionally painful and unpleasant to look at. Also, the treatment for each variation can be different, also depending on the severity.

What are the causes of herpes on the tongue?

The primary cause of oral herpes is Herpes Simplex Virus-1 (herpes HSV-1), commonly appearing in the form of blisters on the tongue, lips, the inner lining of cheeks, gums, and roof of the mouth. The infection can also spread to your throat, nose, and chin.

In the video below, a doctor provides information on what herpes or cold sores are, what they look like, what causes them, and more.

Although there can be multiple ways of coming in contact with the herpes HSV-1 virus, it is commonly spread through the skin or oral contact. Many children are carriers of the virus as they are most likely to get infected from adults through direct contact and common affectionate gestures like kissing and hugging.

The virus is highly contagious and since the infection is asymptomatic, you may never know that you have the infection. Here’s a study from Johns Hopkins Medicine that depicts the extent of infection to be around 50 to 80 percent in adults in the United States with no symptoms whatsoever.

Although for the most part, the infection spreads through direct contact, there are other practices as well that might cause the virus to spread:

  • Eating and drinking from the same utensils    
  • Sharing lip balms, Vaseline, and other cosmetic items  
  • Sharing cigarettes
  • Oral intimacy

What does herpes in the mouth look like?

Herpes often leads to large sores around the lips or on the tongue, but the infection doesn’t cause sores immediately. Rather, at the initial stage of the infection, you might notice flu-like symptoms and headache. The degree of these symptoms may range from person to person, and in many cases, the infection can be asymptomatic too. It is after a few days after the infection that you can develop blisters inside your mouth and affected areas.

These blisters in the elementary stage are red and may cause the area infected to itch and cause irritation while eating and drinking. Over the next few days, the blisters become more painful and fluid starts to develop inside them. Take care while dealing with fluid leaking blisters as the fluid is highly contagious and any surface that comes in contact with it can develop an infection. Over the course of a few days, these blisters become sores and eventually crust over and heal.

What are the different stages of oral herpes?

Regardless of where the infection may be inside the mouth, the different stages of oral herpes are:

Initial Infection

Initial stage of herpes on tongue
Initial stage of Cold Sore on the Tongue

The primary stage includes exposure to the herpes virus and its reproduction that can cause symptoms like headache, fever, muscle pain, and gum pain. In most cases, the infected person may not experience any of these symptoms and might notice some irritation or a burning sensation in the infected area. In the worst cases, people have also reported burning mouth problems. Symptoms during the initial phase of infection can vary from person to person.


In this second stage, the herpes virus spreads from the original infection spot to nervous tissue gatherings in your spine, called dorsal root ganglia. The virus reproduces again in this stage and becomes dormant.

Re-infection or recurrence

Often stimulated by emotional and physical stress, the herpes virus that is silently residing in your body activates again to cause the initial infection symptoms and sores in the mouth and other areas like the neck, chin, and lips.

How to prevent oral herpes

Medical science has always promoted prevention over treatment if possible. And this ideology becomes quite significant in tackling infections like oral herpes that have no cure. You can adopt the following strategies to avoid getting infected from the herpes HSV-1 virus.

  • Avoid direct contact with the infected person: Herpes sores and blisters are quite visible, and you can easily detect the infection in someone with some awareness about the condition. Even if not visible, often people will themselves will let you know they have it. As the virus is contagious you should avoid any form of direct contact with the infected person.
  • Do not share utensils and other items with the infected person: The second common reason for herpes virus spread is through objects that the infected person might have used. You should avoid using objects like utensils, straws, and food items that might carry the virus from the infected person. These practices are common in friends and family, but with the right awareness, it’s everyone’s responsibility to make others aware of their disease and promote preventive measures.
  • Washing items of common use: Another way to decrease transmission of the simplex virus is to regularly wash and sterilize shared utensils in hot water. This way the herpes virus is killed before it can spread.
  • Avoid Oral Intimacy: If you or your partner is suffering from sores and blisters, oral intimacy can lead to the spread of the virus to genitals. This six-year study by the National Center of Biotechnology Information, stresses the ability of the herpes primary infection to spread through physical intimacy. The genital spread of the herpes virus can lead to many medical complications.
  • Stress can lead to recurrence: The herpes HSV-1 virus can reside in your body for years with absolutely no symptoms at all. Emotional and physical stress can trigger and reactivate the virus.

Tongue sores do not require treatment and will generally go away after 9-10 days. If you experience severe pain and irritation while eating or drinking, consult a doctor.
