Your tongue gets injured from a broken tooth, accidental or compulsive biting, braces, false teeth and rough fillings. Hot and spicy foods is another reason for tongue injury. Tongue piercing  causes a puffed up tongue, especially if you are allergic to the metal. Because the tongue has a rich blood supply, any injury heals well. You can rinse with warm salt water, suck on a ice cube or take an over the counter pain killer to ease the discomfort. Avoid hot and spicy foods, smoking and alcohol.



An over reaction of your body to an irritant is an allergy. Ingredients in foods like cow’s milk, nuts, fruits, shellfish, eggs, soy can cause allergic reactions in some of you. Insect bites and antibiotics like penicillin also be the culprits. Because of the reaction, fluid from your blood leaks into the tongue and other tissues and causes a swelling. This is called ‘Angioedema’. You can have other symptoms like swollen lips, face and throat, itchy red skin, dizziness and stomach ache. If your breathing becomes difficult, seek medical help. Otherwise, most symptoms can be controlled with an antihistamine and oral steroids.



Certain toothpastes, mouthwashes, alcohol, tobacco and spicy foods will act as irritants and can induce a reaction in you. However, the effects revert once you remove the offending ingredient. If you find that a specific component is the culprit, then avoid it in the future.


Bacterial can get into the tongue due to a cut from a broken tooth or tongue piercings. Also, fungal infections like oral thrush causes tongue swelling. Occasionally, STD’s ( Sexually Transmitted Disease ) like syphilis or gonorrhoea will bother your tongue. Viral infections like herpes and HPV will mess with your tongue. Your health care provider will prescribe medications to treat the conditions. Once the infection is under control, you will feel better.
