Oral thrush, an overgrowth of a naturally occurring fungus, often appears when the immune system is depressed. Babies, denture wearers, patients with cancer, HIV and other immune-compromising conditions, anemia and diabetes patients, smokers and dry mouth sufferers are all at a higher than normal risk of developing oral thrush. A course of antibiotics can also trigger an attack.
It's rarely serious, but a long-term infection may require treatment. Creamy white lesions on the tongue are one sign of thrush; other symptoms include:
A white spot on the tongue surrounded by a red, inflamed halo is probably a canker sore. These common and recurring lesions can be small or large and appear on its own or in groups. Canker sores are often painful and scraping doesn't remove them.
Viruses, bacteria and immune system issues are some suspected causes of canker sores. Trauma, allergies, stress, cigarette smoking, iron and vitamin deficiencies make you more susceptible.
White or grayish patches called leukoplakia usually appear on the gums, the bottom of the mouth or the insides of the cheeks, but sometimes they appear on the tongue as well. Wiping or scraping does not change their appearance or texture, which may be thick or hardened.
Chewing or smoking tobacco and drinking alcohol increase your chance of developing leukoplakia according to the Canadian Cancer Society. The condition also carries a small risk of developing into oral cancer.
Fuzzy white patches that appear on the sides of the tongue as ridges or folds are symptoms of hairy leukoplakia. These patches result from infection with the Epstein-Barr virus (EBV), which lasts a lifetime but remains dormant in the body.
If a white spot on tongue doesn't go away after a week to ten days, visit your doctor to have it checked. Some conditions, like thrush, may go away on their own, but it's always wise to go see your dentist or doctor for a consultation to make sure it's not something more.
To help keep your mouth fresh and healthy and reduce the risks of white spots and other problems, follow a good oral health routine. Most people experience white spots on the tongue at some point in their lives and for many they're a common occurrence. Though the spots are unlikely to be harmful, they could be a sign of something more serious. If you're concerned, a checkup at your dentist can put your mind at rest.
