Our tongues are covered in tiny sensors which help us distinguish different tastes. Due to trauma, spicy foods, infections, or allergies, these taste buds can become swollen and sore. Swollen taste buds are common and will typically heal on their own within a few days to a week. In cases where treatment is necessary, it will depend on the cause of your swollen taste buds. In this article, we will discuss the most common causes of swollen taste buds, how the condition is diagnosed, and treatment for the condition.
Key Takeaways
- There are several different reasons behind contracting swollen taste buds, but they can happen from something as simple as eating spicy food. You can also get them from more serious cases like an allergic reaction or oral trauma.
- In most cases, swollen taste buds will not require a visit to the doctor or dentist. However, if you continue to have swollen taste buds after a week and they are still painful, you should visit a medical practitioner and get a proper diagnosis
- To lower your risk of swollen taste buds, ensure you adopt a model oral care routine. This includes brushing your teeth at least twice a day, flossing and using mouthwash, as well as visiting your dentist and dental hygienist for regular check-ups
- Stress and anxiety can cause swollen taste buds, showing how closely your oral health is linked to your physical and mental well-being. Taking care of your overall health is important for your entire body and mind.
What is a Taste Bud?
Your taste buds are tiny sensors that line the surface of the tongue. They are housed inside little bumps called papillae and contain sensory cells connected to nerves. As their names imply, taste buds allow you to differentiate between and recognise tastes.
Most people will have around 10,000 taste buds, but you should not be able to feel or see them despite their prevalence. Different areas of the tongue will have different concentrations of papillae and taste buds, with the base containing the most and the back edges the least.
What is a Swollen Taste Bud?
If you can feel or see your taste buds, you are likely experiencing swollen taste buds. Taste buds can become inflamed for several reasons, including allergens and irritating foods, and once swollen, can cause pain or discomfort when eating and drinking.
It is possible to experience a singular inflamed taste bud or a swathe of swollen taste buds on the tongue. Despite the pain that swollen taste buds may cause, the condition is not a serious one, and most cases of inflammation will disappear on their own in just a few days.
Causes of Swollen Taste Buds
A host of triggers can cause or factor into swollen taste buds on the tongue, with some more common than others. If you are wondering ‘why is my taste bud swollen?’, then the following causes may be responsible:
Oral Trauma: Trauma, namely burns from hot food or biting your tongue, can cause inflammation in the mouth and swollen taste buds.
Smoking: Cigarette smoke contains irritants which can contribute to swollen taste buds and a reduction in your ability to taste.
Irritation: If you wear braces, a retainer, or other dental appliances in the mouth, then you may suffer irritation and inflammation on the tongue from them rubbing against it.
Poor Oral Hygiene: The buildup of bacteria in the mouth from poor, or a lack of, oral care can lead to swelling and inflamed taste buds.
Dry Mouth: A lack of saliva can lead to several oral health issues, including the inflammation of taste buds.
GERD: Acid reflux, or gastroesophageal reflux, can irritate the throat and mouth, depending on how far stomach acid travels.
Stress: High stress has been linked to the presence of inflamed or swollen taste buds.
Infections: Some viral infections, including scarlet fever, are capable of making the tongue and taste buds swell up.
Transient Lingual Papillitis: TLP is a common and typically short condition that causes swelling of the papillae and taste buds.
Food: Acidic and spicy foods can irritate the tongue and cause swollen taste buds.
Deficiencies: Some studies have linked deficiencies in iron and B vitamins to swollen taste buds.
Allergies: Allergens contacting your mouth can cause irritation and swollen taste buds.
Diagnosing Swollen Taste Buds
Most cases of swollen taste buds will not be serious and should not require a trip to the doctor. If, however, soreness or swelling lasts beyond two weeks or is accompanied by a fever or constant pain, you should contact a medical professional.
Diagnosing swollen taste buds is a simple task for a doctor. A visual examination where your doctor checks the size, colour, and texture of the tongue should be enough to determine whether you have the condition. A doctor may wish to feel your tongue to determine if any sores are present or perform a biopsy if they believe oral cancer could be present.
Complications of Swollen Taste Buds
Swollen taste buds are not a serious condition. Complications of tongue swelling and irritation should not extend beyond difficulty or pain when eating and drinking. Any further complications will depend on the underlying cause of your irritated taste buds.
Treatment for Swollen Taste Buds
Most instances of swollen taste buds should clear up on their own without the need for medical treatment.
In cases where inflamed taste bud treatment is used, it will focus on curing the underlying cause of the irritation rather than the irritation itself. If infections are causing the swelling, your doctor will prescribe antibiotics or antiviral medications. If swelling is the result of deficiencies, supplements and dietary changes may be recommended to prevent recurring swollen taste buds.
While you wait for the swelling and pain in your taste buds to ease, there are simple at-home methods you can use to soothe discomfort, including:
Sucking or chewing ice
Using a saline rinse to clean your mouth
Avoiding spicy or acidic foods
Preventing Swollen Taste Buds
Sadly, there is no way to completely prevent swollen taste buds, but some lifestyle changes can reduce your risk of swelling. Changes to implement include:
Quitting, or cutting down, cigarette use
Avoiding spicy, acidic, or irritating foods
Maintaining good oral hygiene and regularly visiting the dentist and dental hygienist.
