Common Causes of Tongue Bumps
In some cases, foliate and circumvallate papillae might become larger than usual due to inflammation or irritation. This condition is medically known as transient lingual papillitis. Irritation from chemicals or foods and an accidental bite to your tongue are two common causes. Also, it can be triggered by smoking, nutritional deficiencies, dental appliances, plaque buildup, and alcohol consumption. Fortunately, the symptoms are just temporary and can resolve without treatments. Tongue bumps can also appear as lumps, ulcers, and blisters. These specific spots can result from oral cancer, immune system disorders, allergies, oral herpes, canker sores, or bacterial infections. [2]
