Experiencing pain at the back of your tongue can be unsettling and uncomfortable, impacting everyday activities like eating, speaking, and even swallowing. While there are various reasons for tongue discomfort, one common culprit is canker sores. These small, but often intensely painful, ulcers can appear anywhere inside the mouth, including the tongue, and are a frequent cause of localized pain. Understanding why the back of your tongue might hurt often starts with recognizing the symptoms and causes of canker sores and exploring effective ways to manage the discomfort.
What are Canker Sores and Why Do They Hurt Your Tongue?
Canker sores, also known as aphthous ulcers, are small, shallow lesions that develop in the soft tissues of your mouth or at the base of your gums. Unlike cold sores, canker sores are not caused by the herpes virus and are not contagious. They typically begin with a tingling or burning sensation, followed by the appearance of a small red bump that quickly turns into a white or yellowish ulcer with a red border. When these sores occur on the back of your tongue, they can cause significant pain, particularly because this area is constantly in motion during eating and speaking.
Symptoms of Canker Sores on the Tongue
Identifying a canker sore on the back of your tongue involves recognizing several key symptoms:
- Pain: The primary symptom is pain, which can range from mild to severe. The pain is often described as sharp or throbbing and can be exacerbated by eating, drinking, or even speaking.
- Appearance: Canker sores are typically small, round or oval ulcers with a white or yellowish center and a red, inflamed border.
- Location: While they can appear anywhere in the mouth, canker sores frequently occur on the tongue, including the back of the tongue, as well as the inner cheeks, lips, and base of the gums.
- Sensitivity: The area around the sore may be sensitive to touch, and you might experience increased discomfort when consuming certain foods or drinks.
What Causes Canker Sores on the Back of Your Tongue?
The exact cause of canker sores is not fully understood, but several factors are known to trigger their appearance. These can include:
- Minor mouth injuries: Accidental biting of the tongue, irritation from rough foods, or dental work can sometimes trigger canker sores. Any injury to the delicate tissues inside the mouth, including the back of the tongue, can potentially lead to a canker sore.
- Stress and emotional factors: Periods of high stress, anxiety, or emotional upset can weaken the immune system and increase susceptibility to canker sores.
- Certain foods: Some foods are known to trigger canker sores in susceptible individuals. These include acidic foods like citrus fruits and tomatoes, as well as chocolate, coffee, and certain nuts and seeds.
- Nutritional deficiencies: Deficiencies in certain vitamins and minerals, such as vitamin B12, folate, iron, and zinc, have been linked to recurrent canker sores.
- Hormonal changes: Hormonal fluctuations, such as those occurring during menstruation, can sometimes play a role in the development of canker sores.
- Underlying health conditions: In some cases, canker sores can be associated with underlying health conditions like celiac disease, Crohn’s disease, ulcerative colitis, and Behcet’s disease. However, for most people, canker sores are not indicative of a serious underlying condition.
Home Remedies to Soothe Canker Sore Tongue Pain
Fortunately, most canker sores are minor and will heal on their own within one to two weeks. In the meantime, several home care strategies can help alleviate pain and promote healing:
Diet Changes for Canker Sore Relief
Adjusting your diet can significantly reduce irritation and pain from canker sores:
-
Eat soft, bland foods: Opt for foods that are gentle on the mouth and easy to chew and swallow. Good choices include yogurt, mashed potatoes, soft-cooked eggs, smoothies, and soups.
-
Avoid trigger foods: Steer clear of spicy, salty, and acidic foods, as well as coffee, chocolate, nuts, and seeds, which can exacerbate pain and slow healing.
-
Cold liquids and foods: Cold water, iced tea, ice pops, and frozen yogurt can help numb the area and reduce inflammation. Using a straw can help direct liquids away from the sore.
Over-the-Counter Treatments for Pain Relief
Several over-the-counter (OTC) products can provide relief from canker sore pain:
- Topical numbing agents: OTC numbing gels or creams containing benzocaine or lidocaine (like Orabase) can provide temporary pain relief by numbing the sore area.
- Antimicrobial mouth rinses: Gentle antimicrobial mouthwashes can help keep the sore clean and prevent secondary infection. Look for products containing chlorhexidine or hydrogen peroxide, and use them as directed.
- Milk of Magnesia: Dabbing a small amount of Milk of Magnesia on the canker sore several times a day can help neutralize the acid in the mouth and promote healing.
Other Home Care Tips for Faster Healing
In addition to diet and OTC treatments, consider these home care tips:
- Ice application: Applying ice to the sore can help reduce pain and swelling.
- Pain relievers: Over-the-counter pain relievers like ibuprofen (Advil, Motrin) or naproxen (Aleve) can help manage pain and reduce inflammation. Always follow the dosage instructions on the label.
- Gentle oral hygiene: Continue to brush your teeth gently with a soft-bristled toothbrush, being careful around the canker sore. Avoid harsh mouthwashes that contain alcohol, as they can irritate the sore.
- Avoid tobacco: If you smoke or use spit tobacco, try to avoid it while the canker sore heals, as tobacco products can irritate the mouth and delay healing.
When to Seek Medical Advice for Tongue Pain and Canker Sores
While most canker sores resolve on their own, there are situations when seeking medical advice is recommended:
Signs of Infection
If you notice signs of infection, it’s important to consult a doctor. These signs include:
- Increased pain, swelling, warmth, or redness around the sore.
- Pus draining from the sore.
- Fever.
Persistent or Severe Pain
Contact your doctor if:
- The canker sore is unusually large or deep.
- The pain is severe and interferes with eating, drinking, or speaking.
- The sore does not begin to improve within a few weeks or lasts longer than two weeks.
- You experience recurrent canker sores frequently.
- You have any concerns about the cause of your tongue pain.
While canker sores are a common and often benign cause of pain at the back of your tongue, understanding their symptoms, causes, and home care treatments can help you manage discomfort effectively. If you experience persistent or concerning symptoms, don’t hesitate to seek professional medical advice to ensure proper diagnosis and care.
