Shingles in the Mouth (Oral Herpes Zoster)
Shingles in the mouth usually starts as a deep, aching pain on one side of the face or jaw that feels a lot like a toothache. A few days later, blisters or raw sores show up on that same side, on the roof of the mouth, the gums, the tongue, or the inside of the cheek, and they stop sharply at the middle. Often a rash appears on the skin of the face too.
Shingles in the mouth is a flare of the chickenpox virus along a facial nerve. It causes painful blisters and ulcers on one side of the mouth only, often after toothache-like pain and with a face rash. You can't catch shingles, but blisters can spread chickenpox. Sores usually heal in about 2 weeks. See a doctor the same day: antivirals work better started within 72 hours.

Can you get shingles in your mouth?
Yes. Shingles (herpes zoster) is the chickenpox virus waking back up after years of sleeping in a nerve. Most people get it on the chest or back, but about 1 in 7 cases involve the trigeminal nerve, the big nerve that gives feeling to the face. That nerve has three branches. The upper one (V1) serves the forehead and eye. The middle (V2) and lower (V3) branches serve the teeth, gums, palate, tongue and lips, so when shingles flares in either of them, it can show up inside the mouth.
Oral shingles is much less common than shingles on the body, but we do see it, and it's easy to mistake for a dental problem at first. It's one of several whole-body conditions that can show up in the mouth. Our guide to mouth signs of systemic disease covers the others.
What does shingles in the mouth look like?
We don't have a good open-license photo of oral shingles, so the drawings on this page show the pattern dentists look for. In the mouth you may notice:
- Small blisters that break fast. Inside the mouth, blisters rarely last long. Most people see clusters of shallow, round ulcers with red edges, sometimes merging into a larger raw patch.
- One side only. On the roof of the mouth, the tongue, the gums or the lips, the sores run right up to the middle and stop. That sharp midline cutoff is the biggest clue.
- A band, not a scatter. Sores line up in the area served by one nerve branch, for example the whole left half of the palate and the upper left gums.
- A skin rash on the same side of the face in most people, on the cheek and upper lip (V2) or the jaw, chin and lower lip (V3).
- Pain that seems too big for the sores, often burning, stabbing or deep and aching.
Shingles on the tongue and roof of the mouth at the same time is less common, because the palate belongs to V2 and the tongue to V3. Some people do get both. What stays the same is the one-sided pattern.
Can shingles cause tooth pain?
Yes, and this is the part that trips people up. In the days before any rash or sore appears, the nerve itself is irritated. That can feel exactly like a toothache: a deep, throbbing or burning pain in several teeth on one side, sometimes the whole upper or lower jaw. The teeth may even feel sore to bite on.
Dental journals describe people who had a root canal or an extraction for this pain, only to break out in a shingles rash a few days later. Shingles tooth pain has some tells:
- It spreads across several teeth instead of pointing to one.
- The teeth look healthy, and x-rays and cold tests don't find a cause.
- There may be tingling, itching or a sunburned feeling on the skin of the cheek or jaw on the same side.
- You may feel run down, with a headache or a low fever.
When the story doesn't add up, we'd rather wait a day or two and look again than start an irreversible procedure on a tooth that isn't the problem. A careful exam with dental x-rays and 3D imaging helps rule a real tooth abscess in or out.
Shingles vs. cold sores, canker sores and toothache
Several conditions cause painful sores or one-sided mouth pain. This table shows the differences we look for.
| Shingles in the mouth | Cold sores inside the mouth | Canker sores | |
|---|---|---|---|
| Cause | Varicella-zoster virus (chickenpox virus) reactivating | Herpes simplex virus (HSV-1) | Immune reaction plus triggers. Not a virus. |
| Pattern | Many sores in a band on one side, stopping at the midline | A small cluster in one spot, usually gums or hard palate | 1 to a few scattered sores, either side |
| Where | Palate, gums, tongue, lips, cheek lining in one nerve's area | Firm tissue: gums, hard palate | Soft, moveable tissue: inner lips, cheeks, under the tongue |
| Skin rash | Often, on the same side of the face | Sometimes a cold sore on the lip | No |
| Pain before sores | Often days of toothache-like or burning pain | A day of tingling | Maybe a day of burning |
| Feel sick? | Sometimes fever, headache, tired | Usually not, except in a first infection | No |
| Comes back? | Uncommon | Often, in the same spot | Often, in different spots |
| Treatment | Prescription antivirals from your doctor, started fast | Antivirals help if started early | Topical steroids and comfort care |
Our pages on cold sores, canker sores and mouth ulcers in general go into more detail on each. Two other look-alikes are worth knowing:
- Toothache. A cracked tooth or infected nerve usually points to one tooth, often reacts to hot or cold, and shows up on an exam or x-ray. Shingles pain is spread out and the teeth test normal.
- Trigeminal neuralgia. Brief, electric-shock jabs of pain on one side of the face, often set off by light touch, chewing or a breeze. There's no rash and no sores, and it tends to come and go for months or years.
What causes shingles in the mouth?
Anyone who has had chickenpox, even a case too mild to remember, carries the varicella-zoster virus in their nerve roots for life. Shingles happens when the immune system's hold on that virus slips and it travels down a nerve to the skin or mouth lining. If it's a branch of the trigeminal nerve, you get shingles in the face and mouth.
Risk factors
- Age over 50. Risk climbs sharply after 50.
- A weakened immune system from HIV, leukemia or lymphoma, chemotherapy, an organ or stem cell transplant, or medicines that suppress the immune system, including long-term steroids and some biologics for autoimmune disease.
- Recent illness or physical stress. Many people can point to a hard stretch before it started, though plenty can't.
- Not being vaccinated with Shingrix.
People with HIV, leukemia, or head and neck cancer treatment in their history are more likely to get shingles and to have a longer, more severe case.
Shingles in the mouth symptoms: mouth, face, ear and throat
In the mouth
- Toothache-like pain in several teeth on one side, often before anything is visible
- Burning, tingling or numbness of the gums, palate, tongue or lip on one side
- Clusters of small blisters that quickly become shallow ulcers
- Pain with eating, drinking hot or acidic things, and brushing
Shingles in the mouth and face
Most people with oral shingles also get a band of red, blistering rash on the same side of the face: cheek, side of the nose and upper lip for V2, or jaw, chin and lower lip for V3. A rash on the forehead, around the eye or on the tip of the nose means the V1 branch, which can affect the eye. That needs a doctor the same day.
Shingles in the mouth and ear
When shingles involves the facial nerve near the ear, it's called Ramsay Hunt syndrome. Signs include a painful rash in or around the ear, weakness or drooping of one side of the face, ringing or hearing loss, dizziness, loss of taste on the front of the tongue, and sometimes blisters on the same side of the tongue or palate. This needs prompt medical care.
Shingles in the mouth and throat
Rarely, shingles affects nerves that serve the back of the throat. That causes one-sided throat pain, sores near the tonsil area, and painful or difficult swallowing. See a physician promptly, and go to the emergency room if you have trouble breathing or can't swallow fluids.
All over
Fever, headache, chills, an upset stomach and feeling wiped out are common in the first few days.
Is shingles in the mouth contagious?
You can't give someone shingles. But the fluid in shingles blisters carries live virus, and a person who has never had chickenpox or the chickenpox vaccine can catch chickenpox from it. Mouth sores count, since saliva touches them.
Until every sore has healed and any skin blisters have scabbed over:
- Don't share cups, utensils, lip balm or toothbrushes, and skip kissing.
- Keep any skin rash covered and wash your hands often.
- Stay away from pregnant people who haven't had chickenpox, newborns, and anyone with a weakened immune system.
Shingles isn't contagious before the blisters appear or once the rash has fully crusted.
How long does shingles in the mouth last?
Most cases follow this rough timeline, though people with weakened immune systems can take longer.
Pain is usually worst in the first week. Most people feel much better once the sores heal, but about 10 to 18 percent of people with shingles go on to have nerve pain that lingers for months after the rash is gone. That's called postherpetic neuralgia, and it's more likely the older you are. In the face it can feel like burning, aching or sharp zaps in the teeth, gums or skin, which is another reason to start antivirals early.
Rarely, teeth in the affected area loosen or the gum and bone around them break down during or after facial shingles. If something feels off in that area weeks later, let us know.
Who diagnoses shingles, and with what tests?
Your physician does. That might be your primary care doctor, an urgent care clinic, or a dermatologist. Most of the time the diagnosis is made by looking: a one-sided, banded rash with pain is distinctive. When the picture isn't clear, especially when there are mouth sores but no skin rash, a swab of a sore can be tested for the virus by PCR.
If the rash is near the eye, your doctor will usually send you to an eye doctor the same day. If your face is weak or your hearing has changed, an ENT may be involved.
As dentists, we don't diagnose shingles. What we can do is recognize when a toothache or a mouth sore has the pattern of shingles, document what we see, and help you get to your physician quickly so antivirals can start. That kind of coordination is a big part of our care for medically complex patients.
Treatment for shingles in the mouth
The main treatment is an antiviral pill prescribed by your doctor: valacyclovir (Valtrex), famciclovir (Famvir) or acyclovir. They shorten the outbreak and ease its severity, and they work better the earlier they start, ideally within 72 hours of the first sores or rash. Don't wait to see if it gets better on its own.
Your doctor may also recommend pain medicine. If nerve pain hangs on, they may suggest medicines such as gabapentin or lidocaine patches. Mouth sores themselves are treated with comfort care, below.
Mouth care at home for herpes zoster mouth sores
Antivirals deal with the virus. Mouth care keeps you eating, drinking and comfortable while the sores heal.
- Rinse gently 3 to 4 times a day. Warm salt water (½ teaspoon salt in a cup of water) or a baking soda rinse (1 teaspoon in ½ cup water). Swish and spit.
- Keep brushing, with a soft or extra-soft brush and a mild toothpaste. Go slowly on the sore side. A clean mouth heals faster and is less likely to pick up a second infection.
- Numb before meals if needed, with an over-the-counter oral gel dabbed on the worst spots 10 to 15 minutes before eating.
- Eat soft, cool, bland foods. Yogurt, eggs, oatmeal, smoothies without citrus, mashed potatoes, pasta. Skip acidic, spicy, salty and crunchy foods.
- Drink plenty of fluids. A straw can help steer drinks past the sores.
- Leave dentures out as much as you can if they press on sore areas, and keep them clean.
- Use a cool, damp cloth on any face rash and keep it covered. Don't pick at blisters.
Our home care instructions cover gentle brushing and flossing in more detail.
Skip these
- Alcohol-based mouthwash. It stings and dries the tissue.
- Aspirin, peroxide or salt held right on a sore. These can burn.
- Leftover antibiotics. Shingles is a virus.
- Waiting it out instead of calling your doctor in the first few days.
Over-the-counter options for oral shingles
| Type | What it does | Things to know |
|---|---|---|
| Pain relievers (acetaminophen, ibuprofen, naproxen) | Overall pain control | Take as the label directs. Ask your doctor or pharmacist first if you have kidney, liver or stomach problems, take blood thinners, or are pregnant (avoid ibuprofen and naproxen from 20 weeks of pregnancy on unless your doctor says otherwise). Use children's products and doses for kids. |
| Numbing gels and liquids (benzocaine, lidocaine) | Short-term relief before meals | Wears off in under an hour. Do not use benzocaine in children under 2. Don't numb the back of the throat right before eating, since it can affect swallowing. |
| Protective pastes and films | Cover a sore so food and teeth don't rub it | Work well on single sores. Dry the spot first so it sticks. |
| Alcohol-free rinses | Keep sores clean | Swish and spit. Choose a gentle, alcohol-free formula. |
| Cool compresses and calamine (skin only) | Soothe the face rash | For the skin, not inside the mouth. |
What a dentist can do
- Sort out the toothache. We check the teeth, test them, and take x-rays so a healthy tooth isn't treated for nerve pain, and so a real dental infection isn't missed.
- Recognize the pattern and send you on fast. If your pain or sores look like shingles, we'll tell you so and help you get to your physician the same day. If the rash is near your eye, we'll tell you to be seen right away.
- Document what we see with notes and photos, and share them with your physician if you'd like.
- Treat the mouth. We can recommend or prescribe rinses and pastes to ease the sores, and adjust a denture or smooth a rough edge that's rubbing.
- Follow up. We check the area after it heals, look at any teeth that stay sore, and help sort lingering nerve pain from dental pain.
If you've had odd one-sided mouth pain or sores and want them looked at, our mouth sore and oral medicine evaluations and comprehensive dental exams are good places to start. For sudden severe pain, see our emergency dental care page.
Dental visit tips during and after shingles
- Call before you come in if you have active blisters on your face or in your mouth. We'll usually postpone routine cleanings and fillings until everything has healed, and see you for urgent problems with the right precautions.
- Tell us if your teeth hurt but the sores haven't started yet. Mention any tingling or rash on your skin, even if it seems unrelated.
- After it heals, let us know you had shingles on that side. If the area is still tender, we can numb it more carefully, keep visits shorter and work gently.
- Bring your medication list, including antivirals, nerve pain medicine and anything that suppresses your immune system.
Should I get the shingles vaccine?
For most adults over 50, yes. The CDC recommends Shingrix for:
- Adults 50 and older, given as 2 doses about 2 to 6 months apart. There's no upper age limit.
- Adults 19 and older with a weakened immune system from disease or treatment. The second dose can come 1 to 2 months after the first.
According to the CDC, Shingrix is about 97 percent effective against shingles in healthy adults 50 to 69 and about 91 percent in those 70 and older, and about 91 percent effective against postherpetic neuralgia in adults 50 and up. You should still get it if you've already had shingles (wait until the rash is gone) or if you had the older Zostavax vaccine. Ask your physician or pharmacist whether it's right for you.
Shingles in the mouth in people at higher risk
- Weakened immune system. People on chemotherapy, transplant medicines, biologics or long-term steroids, and people with HIV or blood cancers, can have more widespread or longer-lasting sores and more complications. Call your medical team at the first sign. If you've had cancer treatment in the head and neck, our head and neck cancer dental care page explains how we work with your oncology team.
- Older adults. Shingles is most common, and lingering nerve pain more likely, after 50 and especially after 70. Vaccination is the most effective protection.
- Pregnancy. If you're pregnant and get shingles, call your OB right away to talk about treatment. If you're pregnant and have never had chickenpox, stay away from anyone with active shingles or chickenpox.
- Children. Shingles is uncommon in kids but does happen, usually in children who had chickenpox very young or have a weakened immune system. Call the pediatrician. Avoid benzocaine numbing products under age 2.
- Denture wearers. Leave the denture out when you can, clean it daily, and let us adjust any spot that rubs once things heal.

Shingles in the mouth FAQ
Can you get shingles in your mouth?
Yes. When shingles affects the middle or lower branch of the trigeminal nerve, it causes blisters and ulcers inside the mouth on the palate, gums, tongue, lips or cheek lining. The sores are on one side only and stop at the midline. Most people also get a rash on the same side of the face.
What does shingles in the mouth look like?
Clusters of small blisters that break quickly into shallow, painful ulcers with red edges. They line up on one side of the mouth, for example half of the roof of the mouth and the gums on that side, and stop sharply at the middle. A red, blistering rash on the same side of the face is common.
Is shingles in the mouth contagious?
You can't catch shingles from someone, but the virus in the blisters can give chickenpox to a person who has never had chickenpox or the vaccine. Until the sores heal and any skin rash scabs over, don't share cups or utensils, skip kissing, and stay away from pregnant people, newborns and anyone with a weak immune system.
How long does shingles in the mouth last?
Mouth sores usually heal in about 10 to 14 days, and a face rash clears in 2 to 4 weeks. Pain can start several days before anything shows. About 10 to 18 percent of people with shingles have nerve pain that lingers for months afterward, called postherpetic neuralgia.
Can shingles cause tooth pain?
Yes. Shingles in the face often starts with deep, burning or throbbing pain in several teeth on one side, days before the rash or sores appear. The teeth test healthy and x-rays look normal. If a toothache comes with tingling or a rash on the skin of the same side, call your doctor before having dental work done on it.
Can you get shingles on your tongue?
Yes. Shingles on the tongue comes from the lower (mandibular) branch of the trigeminal nerve. It causes painful sores on one half of the tongue that stop at the center line, often with sores on the lower gums, lower lip or chin on the same side.
What is the treatment for shingles in the mouth?
Prescription antiviral pills, such as valacyclovir (Valtrex), famciclovir (Famvir) or acyclovir, from your physician. They work better when started within 72 hours of the first sores or rash. For the mouth, gentle salt-water rinses, soft cool foods, a soft toothbrush, over-the-counter pain relievers and numbing gel help you stay comfortable while it heals.
Is it shingles or a cold sore inside my mouth?
Cold sores inside the mouth are usually a small cluster in one spot on the gums or hard palate, and they tend to come back in the same place. Shingles makes a band of many sores along one whole side of the mouth that stops at the midline, often with face pain and a rash. Both are viruses, but they're different ones, and a doctor can swab a sore to tell for sure.
Should I go to a doctor or a dentist for shingles in my mouth?
See your physician first, the same day if you can, because antiviral medicine works better when started early. Go to an eye doctor or the ER right away if the rash is near your eye or on the tip of your nose. See your dentist if you have one-sided tooth pain with no rash and aren't sure of the cause, or if mouth sores or tooth pain linger after the shingles clears.
Can shingles affect your mouth and throat?
Rarely, shingles involves nerves that serve the back of the throat. That causes one-sided throat pain, sores near the tonsils and painful swallowing. See a physician promptly, and go to the emergency room if you can't swallow fluids or have trouble breathing.
Can shingles in the mouth come back?
It can, but most people have only one episode. Repeat episodes are more likely in people with weakened immune systems. Getting the Shingrix vaccine after you recover lowers the chance of another round.
Should I get the shingles vaccine?
The CDC recommends 2 doses of Shingrix for adults 50 and older, and for adults 19 and older with a weakened immune system. It's recommended even if you've already had shingles, once the rash is gone, or had the older Zostavax vaccine. Ask your physician or pharmacist about timing.
Toothache on one side, or sores that stop at the middle?
If you're in the Jacksonville area and have one-sided mouth pain or sores, call your physician first if it might be shingles. When the pain looks dental, or sores and tooth pain linger after shingles, we're glad to take a look and work with your doctor.
