From French kisses to the Bronx cheer, our tongues are a constant source of delight and derision.
The tongue is covered with several types of small nodules called papillae, some of which contain our taste buds. Like the hairs on our heads, they continuously grow and shed. The papillae on the back of the tongue shed more slowly than those in the front. They also tend to be longer, making them more susceptible to bacterial and yeast infections. Indeed, the tongue can have quite a taste for trouble.
Our mouths can harbor more than 6 million bacteria. Some are good, some bad. Which of the more than 600 different kinds you have milling aroung depends on where you live and even your weight. for example, South Americans, North Americans, Swedes have different bacteria. And the mouth bacteria of overweight women are different from those of normal weight women.
Small lumps or bumps on both sides of your tongue are usually non-cancerous. But if you have bumps on only one side, it may be a warning sign of cancer.
