A sore tongue can happen for various reasons, such as an injury, a mouth ulcer, or an underlying health condition. Some causes may need medical treatment.
Whether it’s the side, the tip, or the back of your tongue, a sore tongue can be hard to ignore. It can make it hard to speak or eat.
A sore tongue often resolves without treatment, but it can sometimes indicate a more serious issue, such as a vitamin deficiency, infection, or chronic condition.
Here, we look at some of the most common causes and when to see a doctor.
Surgery, cutting the tongue, biting it, grinding the teeth, or eating something hot or sharp can cause trauma to the tongue.
A severe injury may need medical attention, but minor trauma will heal in time without intervention.
Topical pain relief can help manage discomfort, especially when eating.
These bumps are inflamed taste buds. The exact cause is unclear, but stress and hormonal changes may play a role.
They can be painful but usually resolve without treatment in a few days.
Oral thrush, also called candidiasis, is a type of fungal or yeast infection of the mouth or throat. It can cause pain, redness, a cotton-like feeling in the mouth, loss of taste, and white patches that look like cottage cheese.
Oral thrush is
- infants less than 1 month of age
- older adults
- people who wear dentures
- those with a weakened immune system

A doctor may prescribe antifungal medications.
Other infections may also give you a sore tongue, such as:
- hand, foot, and mouth disease
- human papillomavirus (HPV)
- scarlet fever (may also be caused by a bacterial infection such a Strep throat)
Treatment options will depend on the cause. A bacterial infection, such as syphilis, will need antibiotics.
These are whitish in appearance or sometimes red, yellow, or gray.
- a minor trauma, such as biting the tongue
- eating something hard or sharp
- stress or anxiety
- an allergy or sensitivity to a food or substances in oral hygiene products
- some chronic conditions, such as celiac disease
- viral infections
Ulcers usually disappear after a week or two, but some may take weeks or months to heal.
Over-the-counter pain medications, such as gels, can often help ease the discomfort.
If certain foods make your tongue hurt, it may be a sign of oral allergy syndrome, also known as pollen-food syndrome. It mostly results from a sensitivity or allergy to substances in raw fruits, vegetables, and certain tree nuts.
Along with a sore tongue, you might experience:
- an itchy mouth
- a scratchy throat
- swelling of your lips, mouth, or tongue
If your reaction is severe, a doctor may suggest you carry an epinephrine auto-injector.

Oral cancer can sometimes cause a sore tongue.
Oral cancer may not cause pain in the early stages, so it’s a good idea to head to your doctor if you notice a lump, sore, or other lesion that lasts 3 weeks or longer, even if there is no pain.

It’s unclear why some people develop Sjögren’s syndrome. Genetic factors and exposure to some viruses may contribute.

Call your doctor or dentist if you notice any changes in your tongue that concern you, such as:
- change in color
