Tongue bumps can appear for all kinds of reasons. Accidentally biting your tongue can result in bumps, or they could be due to something more serious. If you're concerned about a bump on your tongue that isn't going away, schedule an appointment with your dentist or physician.

Natural Bumps on the Tongue

Papillae are the small, natural bumps that cover the surface of the tongue. The four types of papillae are:

  1. Filiform
  2. Fungiform
  3. Circumvallate
  4. Foliate

All of the types except filiform contain taste buds. Filiform papillae mostly appear at the back and center of the tongue, fungiform papillae are located on the sides and tip, circumvallate papillae appear at the back of the tongue and foliate papillae sit just in front of them and on the sides of the tongue

Causes of Enlarged Tongue Bumps

Circumvallate and foliate papillae are normally large enough to be seen with the naked eye, but sometimes a papilla grows unusually large due to irritation or inflammation. This condition is called transient lingual papillitis. An accidental bite to the tongue or irritation from foods or chemicals can cause enlarged papillae. Transient lingual papillitis may also be caused by nutritional deficiencies, smoking, alcohol consumption, plaque buildup or dental appliances. The condition is temporary and often resolves on its own.

Tongue bumps can appear as blisters, ulcers and lumps. According to the Merck Manual, other causes of bumps on the tongue include canker sores, bacterial infections, oral herpes, allergies, immune system disorders and oral cancer. A bump can also develop on the side of the tongue in the space created by a missing tooth. Although most cases of bumps on the tongue are harmless, unexplained white or red areas, sores or hard lumps on the tongue should be examined by a medical professional as soon as possible.

Prevention

You can prevent tongue bumps by avoiding the triggers that cause them. Take care when chewing your food and wear a mouth guard while playing sports to avoid accidentally biting your tongue. Avoid eating foods that cause mouth irritation to lower your chances of developing enlarged papillae. Maintain a good oral care routine, including brushing your tongue when you brush your teeth.

Healing Time

Treatment is rarely necessary for most cases of tongue bumps, including canker sores and enlarged papillae due to tongue injury. Drinking plenty of water and rinsing with warm salt water can assist the healing process. Topical over-the-counter treatments like oral numbing gels and canker sore medication may help numb any discomfort. However, if the condition persists for longer than a week or becomes more severe, visit a dental professional for an evaluation.

Bumps on the tongue can be annoying and tedious, but most bumps are harmless and disappear without any treatment. See a medical professional if you have a bump on your tongue that doesn't go away or that gives you another cause for concern.

How Is Tobacco a THREAT TO ORAL HEALTH?

Tobacco's greatest threat to your health may be its association with oral cancer. The American Cancer Society reports that:

  • About 90 percent of people with mouth cancer and some types of throat cancer have used tobacco. The risk of developing these cancers increases as people smoke or chew more often or for a longer time.

  • Smokers are six times more likely than nonsmokers to develop these cancers.

  • About 37 percent of patients who continue to smoke after cancer treatment will develop second cancers of the mouth, throat or larynx. While only 6 percent of people who quit smoking will develop these secondary cancers.

  • Smokeless tobacco has been linked to cancers of the cheek, gums and inner surface of the lips. Smokeless tobacco increases the risk of these cancers by nearly 50 times.7
