In this article, we will go over the common questions about the oral herpes on the tongue like: What causes herpes on the tongue? What are the symptoms of oral herpes and what it looks like? And what are the treatments and preventions for this viral mouth infection?
What is oral herpes (cold sores)?
Oral herpes, also called the cold sores or fever blisters, is a painful chronic lesion caused by herpes simplex virus. There are two types of herpes virus: the herpes simplex virus type 1(HSV-1), which is associated with oral herpes, and the herpes simplex virus type 2 (HSV-2), which causes genital herpes. But both of them can affect the mouth and genitals. Once affected by the virus, it remains in the body and stay dormant until reactivates. Some people may show no symptoms, but others will have painful sores. You may also have periodic outbreaks, which the sores appear again.
Is oral herpes common?
The herpes simplex virus (HSV), or simply herpes, is a quite common infection. Oral herpes is contagious and is transmitted by oral contact through saliva or by the skin-to-skin contact with the people who have the virus. Therefore, it is easily contracted from one person to another such as when kissing or using shared utensils as well as by using towels and other personal care objects that belong to the infected person. And it can be spread with oral sex.
Even when not visible as a sore, the virus can be transmitted.
According to an estimate by World Health Organization in 2016, 67% of the population, or 3.7 billion people under the age of 50, live with the herpes infection.
What causes oral herpes on the tongue?
Oral herpes is caused by herpes simplex virus, mainly by type 1 (HSV-1). Both types of the herpes, HSV-1 or HSV-2, can spread to the face and genitals once infected with the virus.
Since the HSV virus is highly contagious, it is prevalent and affect majority of people with at least one form of the herpes types. Like HSV-1, which is acquired mostly during childhood. With age, the risks of virus activity increases and certain body conditions, such as stress, hormonal changes (e.g., puberty, menstruation), and UV sun exposure can trigger the sores to appear. Although most people with the oral herpes infection are asymptomatic and show no symptoms, but the infection is lifelong and appear frequently over the years. It varies from mild to severe when erupts.
Oral herpes is transmitted when you come into the infected person closely such as when:
- Having oral intimacy
- Using razors, towels and other personal care items
- Eating or drinking from shared utensils
- Using creams and other cosmetics of the infected person
Where does oral herpes infection occur?
Usually, blisters form around or on the lips (labial herpes) and areas surrounding your mouth and can spread to the nose, chin and cheeks. But oral herpes can occur inside the mouth, on your tongue and roof of the mouth. Sometime you can expect that herpes infection appear on the hand and other areas on your skin.
With the other variation, genitals herpes, sores affect the sexual organs.
Generally, oral herpes can appear:
- On or around the lips
- Roof of the mouth
- Chin and on the cheeks
What does oral herpes infection look like?
The herpes comes as fluid-filled blisters that are usually formed in a tiny group of bubbly patches or one single sore. It has a red base and when the blister ruptures after a day or two, it leaves a red ulcer and forms a scab with dry, yellowish crust on top. The blisters are painful and it take 2-3 weeks to heal from the sore without scarring the area.
The infection does not result into blisters immediately and you may have certain symptoms similar to those in the flue. You may have symptoms such as:
- Swollen lymph nodes
- Pain in the gums
- Fatigue and muscle pains
Depending on the individual, the severity of the herpes infection varies.
What are the different stages of oral herpes infection?
Herpes simplex virus goes through three stages once infection occurs. Whether it is oral herpes (cold sores) or other variations, the virus passes through primary infection, latency stage and recurrence.
- Primary infection:
The first stage of infection involves the exposure to the virus from skin or mucous membrane and the reproduction. If you are asymptomatic, so no sores and symptoms may be detected. Otherwise, headache, fever, muscle pain, gum pain and swollen lymph nodes are common symptoms you will experience. The blisters appear on the infected area and you will experience:
- Feeling of itchy and burning on the site. Before coming of the sore, burning and itchy feelings cause discomfort on the infected site, which show that the sore is about to erupt like around the lips or inside the mouth on your tongue.
- Eruption of the blisters. The small, fluid-filled blisters that occupy the infected area appear and form a patch with a red base and sometimes it can be a group of sores.
- Bursting of the blisters. The sores start to crust over and ooze with a yellowish liquid. It then forms shallow, crusted, and dry spots on the skin or inside the mouth.
The virus reproduces and becomes inactive until it is triggered. Meanwhile, it inhibits the mass nerve tissues in the spine, which is called dorsal root ganglion.
The infection can appear again usually on the same site, causing sores which last 2 to 3 weeks before it heals. You will most likely experience milder herpes infection than your first exposure to the virus.
Risk factors & complications of oral herpes infection
Oral herpes, or as is it termed cold sores, go away on their own without treatments. But if your immune system is weakened and you have certain conditions, then you should see a doctor or dentist like in case of:
- Immunocompromised individuals in which herpes sores may take longer to go, such as people who are undergoing chemotherapy or people with conditions such as HIV/AIDS.
- People with Eczema (atopic dermatitis), which is a skin condition, can experience medical emergency with cold sores and require immediate care.
- Eye infection in which the virus can potentially cause infections in the eye. The virus can spread to the eye with repeated occurrences, which increases the chance that you may have touched your eyes with the same hand or object infected with the sores.
- Severe symptoms or high frequency of the infection which require doctor management and medical tests. Your doctor will explain the reason for repeated occurrence of the infection or may diagnose an underlying condition.
How to prevent oral herpes?
As herpes virus is contagious and transmission is easy, you need to pay more attention on ways that it can spread. Infections such as oral herpes can be aesthetically problematic when occur around the mouth (which normally they do) and cause discomfort especially when they arise in the mouth and on your tongue.
If you are infected with the virus, it is reasonable to take precautions and avoid spreading it to other people. And if you don’t have the infection, you need to be careful on physical contact with people who have the sores on their body. Try to prevent herpes virus – both HSV-1 and HSV-2– from entering your body with the following ways:
- Avoid kissing and skin-to-skin contact while sores are present.
The saliva of the infected person bears the infection and kissing should be avoided. Also, once herpes sores come into contact with the skin, they infect other people easily. Avoid direct contact when blisters are present. Because of highly contagious liquid that leaks from the sores, you should be aware not to touch other parts of your body to prevent more progression to other areas.
- Always wash your hands.
During the time of your cold sores, try to keep your hands clean regularly.
- Avoid sharing utensils and other personal items.
Sharing items like towels, shavers, utensils, lip balms, and cosmetic objects can easily transmit the virus. Therefore, you should let others know about this and keep your personal objects away from other people or your family members.
- Lower the recurrence chances.
The herpes simplex virus resides in the body and it may show up again. You should therefore try as much to prevent further recurrences. As a preventive way besides hygiene measurements that you follow daily, reduce your emotional stress and avoid other possible triggers like intense sunlight exposure. You can also use sunblock on your lips which is the most common spot for reappearance of the cold sores.
