Herpes on the tongue is quite common, which makes it even more important to learn about prevention and treatment for the sake of your dental health. This infection can lead to anything from subtle irritation to blistering sores.

Herpes on Tongue
Cold sores or herpes on your tongue can be very painful

Because the virus can be easily transmitted through skin-to-skin or oral contact, many people have this condition. A 2012 study from the World Health Organization estimates that about 3.7 billion people under the age of 50 live with this chronic condition.

Oral herpes can occur in different areas

Oral herpes doesn't just occur on the tongue. It can appear on the:

  • Throat
  • Gums
  • Roof of the mouth

For some people, symptoms may even appear on the upper lip, inside the nose, or on the cheek or chin. All variations of this disease can be exceptionally painful and make you feel self-conscious. Treatment will differ based on the location and the severity.

What causes herpes on the tongue?

The primary cause of oral herpes is herpes simplex virus-1 (HSV-1), commonly appearing in the form of blisters on the tongue, lips, inner lining of cheeks, gums, and the 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 cold sores are, what they look like, what causes them, and more.

Lesson on Cold Sores (known as Herpes Labialis). Cold sores are a cutaneous manifestation of infection with the herpes simplex virus (HSV), which presents as an eruption of painful cluster of vesicles. During the primary infection, this episode of infection can last longer with possible systemic symptoms. After resolution of symptoms, the infection can lie dormant within our bodies. After something that may cause us to become immunosuppressed, HSV can reactivate and cause a recurrent infection. Lips are not the only part of the body where herpes can manifest – there are a variety of cutaneous and mucosal manifestations that we talk about in this lesson.

Although there can be multiple ways to come into contact with the HSV-1 virus, it is commonly spread through skin or oral contact. Many children are carriers of the virus. They are most likely to get infected by adults through direct contact and affectionate gestures like kissing and hugging.

The virus is highly contagious, but the infection can be asymptomatic, meaning you may never know that you have the virus. A study from Johns Hopkins Medicine estimates that 50 to 80 percent in adults in the United States have no symptoms whatsoever.

Although the infection usually spreads through direct contact, other behaviors can 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 on the mouth look like?

Herpes often leads to sores on the lips or on the tongue, but the infection doesn’t cause sores immediately. At the initial stage of the infection, you might notice flu-like symptoms and headache.

The severity of these symptoms may vary from person to person, and in many cases, the infection can be asymptomatic. Blisters can develop a few days after the infection.

These early stage blisters are red and may cause itching and irritation while eating and drinking. Over the next few days, the blisters become more painful and fluid starts to build up inside them. The fluid is highly contagious, and over the course of a few days, these blisters crust over and heal.

What are the different stages of oral herpes?

Regardless of where the infection may be inside the mouth, there are different stages of oral herpes you might experience, including infection, latency and recurrence:

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, which can cause symptoms like headache, fever, muscle pain, and gum pain.

In most cases, you may not experience any of these symptoms and might only notice irritation or a burning sensation in the infected area. Symptoms during the initial phase of infection vary from person to person.


In the second phase, the herpes virus spreads to nervous tissue gatherings in your spine, called the dorsal root ganglia. The virus reproduces and becomes dormant.

Re-infection or recurrence

The herpes virus can potentially hibernate in your body and you'll never see it again. However, emotional and physical stress can cause recurrences at any time.

How to prevent oral herpes

Medical science has always promoted prevention over treatment if possible. This is particularly important with infections like oral herpes, which have no cure. Try these strategies to avoid getting infected with the HSV-1 virus.

  • Avoid direct contact with an infected person: Herpes sores and blisters are visible, meaning you can easily detect them. Even if it's not visible, people will sometimes will let you know that they have it. Because the virus is contagious, you should avoid direct contact.
  • Do not share utensils and other items: Another common cause of the herpes virus spreading is through objects. You should avoid sharing things like utensils, straws, and food that can transmit the virus. These practices are common among friends and family, but it’s everyone’s responsibility to make others aware of their disease and promote preventive measures.
  • Washing common items: Another way to decrease transmission of the simplex virus is to regularly wash and sterilize shared utensils in hot water. This kills the herpes virus before it can spread.
  • Avoid oral intimacy: If you or your partner is suffering from sores and blisters, oral intimacy can lead to spreading the virus to the genitals. This six-year study by the National Center of Biotechnology Information notes 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 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.

How do you treat herpes on the tongue?

Oral herpes on the tongue will go away on its own, but having said that, the sores can be quite painful and irritating.

Consulting a physician should be the first step towards treatment. Providers usually prescribe a topical anesthetic to relieve pain and may recommend additional medications depending on the severity of the herpes sores symptoms. However, there are some at-home practices to treat herpes sores on your tongue.

  • Keep the infected area dry and clean: Regularly sterilizing and keeping the infected area clean will not only prevent the infection from spreading but also make a faster recovery possible. You will gradually see results—herpes sores inside your mouth will crust faster and stop spreading. However, you need to be meticulous about care. Keep items like cotton and purified water with you at all times.
  • Natural remedies: There are plenty of naturally occurring liquids and compounds that have antiviral and antibacterial properties. Some of these compounds include essential oils, lemon balm, milk, and petroleum jelly. Our natural mouthwash guide has more details.
  • Over-the-counter medication: Many over-the-counter medications like Abreva and Zilactin help with oral herpes. They can be bought online, and some are appropriate for children.
  • Zinc oxide creams: Quite effective in treating herpes under the tongue, zinc oxide creams can be applied to deter the spread of the virus. 
  • Maintain good oral hygiene: A good oral routine always works wonders for common oral issues, even with chronic problems like oral herpes.

These remedies don't rely on having to go to the doctor, but your symptoms may not necessarily be tongue herpes, and you might be trying to treat the wrong disease. Therefore, it’s always recommended to consult a doctor. Home remedies can work well if you're treating a recurrence.

No more than your toothpaste, a toothbrush, and floss


Herpes on the tongue and other areas of the mouth is a common disease. The contagious nature of the virus makes it difficult to avoid catching.

While symptoms are not life-threatening, they can cause pain and discomfort and temporary aesthetic side effects. Many people who have herpes may not even know it because they rarely or never have symptoms. This makes viral transmission even easier.

The good news is that herpes is treatable, and if you follow care guidelines, it doesn't need to be a huge inconvenience on your life or oral health. It is, however, a good reason to maintain good oral hygiene practices. If you do have it, let someone know before sharing utensils or engaging in intimate activities like kissing.


Why am I getting sores on my tongue?

The sores that you might be seeing on your tongue may be a result of the simplex virus, which causes herpes inside the mouth. This can often be accompanied by blisters on your tongue. In addition, it can affect the lips, gums, the inner lining of your cheeks, and the roof of the mouth. These blisters gradually become fluid-filled sores.

If you are not careful, the fluid from these sores can lead to the infection spreading to other areas like your throat. The sores on the tongue or in your mouth might recur because the simplex virus can reside inactive for years in the body. Tongue sores will generally go away after 9-10 days.

If you experience severe pain and irritation while eating or drinking, consult a doctor.

Can you get oral herpes on your tongue?

The tongue is actually one of the most common areas to get infected with oral herpes. Ranging from inflamed bumps to blisters and sores, the infection can cause irritation while eating or drinking.

Since the virus is quite contagious you should refrain from sharing utensils to avoid the spread. Often, adults transfer viruses through a kiss or hug to children.

Also, for the sake of your partner’s health, use protection during oral intimacy, as it can lead to the spread of the virus to the genitals and which can lead to serious medical complications.

What does herpes on the tongue look like?

The infection may manifest starting with small, shallow, gray-colored ulcers with a red base. Thereafter, they turn into crusted, scabbed, dry and yellow blisters. For some serious cases, a grayish coating on the tonsils may appear and the patient may also experience a sore throat with shallow ulcers.
