What Causes a Sore Tongue?

When you have a sore tongue, it will be painful and may be difficult to chew, swallow, or talk. Exact symptoms and characteristics depend on the cause. A sore tongue can be swollen, inflamed, discolored, or marked with blisters or sores. Read on for specific causes.

Canker Sores

Canker sores can develop anywhere on the tongue or mouth. They are open white or yellow areas with a surrounding red area. Causes include viruses, stress, or mouth injury.

Trauma

Trauma is any injury to the tongue. Examples include accidentally biting the tongue while chewing food, experiencing seizures, cuts and scrapes, and injuries related to sports or motor vehicles. Some traumas will resolve on their own, while others require suturing with absorbable stitches, or even surgical treatment.

Chemotherapy

Chemotherapy can damage the cells lining the mouth, throat, and gastrointestinal tract, leading to painful ulcers or sores. Tongue pain from chemotherapy can lead to dehydration, undereating, and weight loss.

White or yellow film or patches and pus can occur in the mouth or the tongue. Healing won’t start until chemotherapy completely ends. Then, it may take anywhere from two to four weeks.

Oral Thrush

Thrush (oral candidiasis) is an uncommon type of fungal infection caused by yeast. It's most prevalent in cases of diabetes, cancer, or human immunodeficiency virus (HIV) or AIDS, and in people with dry mouth, who wear dentures, or who smoke.

Thrush symptoms include:

  • Pain while eating and swallowing

  • Dry mouth

  • Redness or soreness

  • White patches on the tongue and inner cheeks, roof of mouth, and throat

  • Irritation and skin cracking at the corners of the mouth

Herpes Simplex (Fever Blister or Cold Sore)

Herpes simplex virus can cause painful blisters on the tongue, mouth roof, gums, and lips. Herpes blisters burst after a day or two, releasing virus-containing fluid. Then the sores form scabs or crusts. Herpes sores typically last a week to 10 days. Medications can help shorten outbreak frequency and severity.

Burning Mouth Syndrome

Burning mouth syndrome is also known as glossodynia, oral dysesthesia, or burning tongue. It's an uncommon but painful, chronic condition affecting the tongue and has no obvious cause. It causes tongue numbness and tingling, and may also cause mental health effects like anxiety or depression. People can also experience secondary burning tongues from medical conditions like anemia or infection, including oral thrush.



Other Causes of Mouth Sores and Pain


According to the American Cancer Society, other causes of mouth sores and pain are:

  • Alcohol and tobacco use (smoking and chewing)

  • Certain immunotherapy drugs

  • Dehydration

  • Insufficient oral hygiene

  • Lack of vitamins or protein

  • Oxygen therapy

  • Radiation treatment to head and neck

  • Various infections

Sore Tongue Self-Care and Home Remedies

Self-care and home remedies focus on maintaining good oral hygiene, easing symptoms, and preventing health complications like infection.

Maintain Good Oral Hygiene

Maintaining good oral hygiene by brushing and flossing your teeth twice daily removes bacteria and prevents dry mouth and the risk of oral infections that may lead to sore tongue.

Saltwater Rinse

Saltwater rinses help maintain good oral hygiene, prevent infection, and ease pain from sores.



Takeaway

To make a saltwater rinse for a sore tongue, mix 1 teaspoon of table salt with 8 ounces of lukewarm water. Gargle for around 30 seconds and spit out.



Rinse the Mouth With Cool Chamomile Tea

Rinsing your mouth with cool or room-temperature chamomile tea can help promote healing while easing symptoms. Chamomile has anti-inflammatory and pain-relieving properties. In one randomized control study published in 2023, the chamomile group experienced reduced pain and speedier recovery from dry sockets (post-extraction alveolar osteitis). A dry socket occurs when the blood clot that forms where the tooth was removed is lost, dissolves, or doesn't fully form before the wound is healed, exposing the bone and nerves to air.

Use Sage as an Herbal Remedy

If inflammation is causing tongue pain, sage mouth rinses may help. Sage has demonstrated anti-inflammatory properties.

Apply Honey to the Sore

Applying honey to the sore can also help ease pain and promote healing. One meta-analysis found consuming honey after a tonsillectomy significantly reduced pain and promoted healing. Avoid using honey for children under a year old.

Be Mindful of Foods and Drinks

When your tongue is sore and your mouth is healing, be mindful of the foods and drinks you consume to prevent injury and support recovery. Consider avoiding or limiting foods and drinks that could be irritating.



Foods to Avoid

The following food and drink might be irritating if you have sore tongue:

  • Acidic foods

  • Carbonated beverages

  • Hot foods

  • Sharp/crunchy snacks

  • Sour foods

  • Spicy foods



Avoid Smoking

Smoking irritates the tongue, making it harder for your tongue to heal. Avoiding smoking helps support your immune system functioning, reduces irritation to the sore tongue area, and speeds up recovery time.

Medical Treatments for a Sore Tongue

Medical treatments for sore tongue target the underlying cause. Consulting with a healthcare professional for a proper diagnosis and treatment can ensure a speedy recovery and can prevent complications like infection.

Pain Medication

Over-the-counter pain reilief medications and prescription medications can help alleviate pain. Bear in mind that pain medication treats symptoms, not the underlying cause.

Topical Gels

Topical gels can be used to treat viral infections or relieve pain. OTC options can help treat canker sores.

Prescription Mouthwash

Prescription antiseptic mouthwash can be particularly useful for helping prevent infection and promote healing.

Vitamin Supplements

If sore tongue is caused by a vitamin deficiency, treatment may likely include taking a vitamin supplement. Vitamin B2 or riboflavin deficiency, for example, can cause sore tongue. In this case, taking vitamin B2 targets the underlying cause.

Medication to Stimulate Saliva

Medication to increase saliva production, such as the oral tablet Salagen (pilocarpine), can help with chronic dry mouth causing sore tongue.

Antibiotics

Antibiotics are used to treat an underlying bacterial infection causing sore tongue symptoms. Strep throat and whooping cough can cause sore mouth and tongue from coughing and dry mouth, and these infections can be treated with antibiotics.

How Long Does a Sore Tongue Take to Heal?

Recovery time for sore tongue depends on cause and treatment follow-through. For example, minor tongue bites from chewing can heal within days but major injuries may take longer.

When to Contact a Healthcare Provider

There are warning signs that indicate the need for medical attention. If you have returning or worsening symptoms, it's time to contact a healthcare provider.

Seek immediate care in the following tongue trauma cases:

  • Flesh has been torn from the tongue (i.e., partial amputation).

  • The wound is larger than 2 centimeters.

  • The wound is complex (i.e., lacerations are bisecting or crossing over each other, gaping, U-shaped, or include large skin flaps).

  • There is persistent bleeding (i.e., your efforts to stop the bleeding are not working).
