Thrush can be characterized by the appearance of a white coating on the tongue, and it is the result of a Candida bacteria, or yeast, overgrowth in the body. Treating tongue thrush naturally requires a multi-faceted approach combining dietary changes, topical applications and supplements to help re-regulate the digestive and immune systems. Here is a step-by-step guide to help treat tongue thrush naturally.

Eliminate foods that feed Candida bacteria. Sugary foods, such as candy, juices, white breads and white flour, are the leading contributor to Candida overgrowth, and should be avoided at all costs. Other foods to avoid are cheeses and nuts that may contain mold.

Take a Probiotic supplement, which you can find at any health foods store or natural foods market in the refrigerated section. Probiotics replenish the healthy bacteria in your digestive tract, creating an environment that allows nutrients to reach your body's organs and systems.

Take a vitamin C supplement. Vitamin C helps boost your immune system, helping your body fight off infections and eliminate harmful bacteria, such as the Candida bacteria that causes tongue thrush. Vitamin C supplements can be found in chewable form, pill form or in powder form to be mixed with water.

Rinse your mouth and tongue daily with a baking soda rinse. Baking soda, or Sodium Bicarbonate, is one of the leading Candida fighters, and quickly kills the bacteria that causes tongue thrush. To make a baking soda rinse, combine 2 tbsp.baking soda with 1 cup of water, and swish it in the mouth for 1 minute.
