**Abstract**

Probiotics are living microorganisms that induce health benefits and advantages on the host, especially when it is used in an adequate amount. Over the years, different definitions of probiotics are established based on their mechanisms, site of action, delivery format, method, or host. As probiotics have various effects, they are used in different areas and one of them is dentistry. Approximately 150 species of yeast are referred to as Candida. Normally, Candida lives without causing harm to its environment which in the most cases is the mucus membranes of various parts of the body, including the ears, eyes, gastrointestinal tract, mouth, nose, reproductive organs, sinuses, skin, stool, and vagina. These mucus membranes are known as beneficial flora and the yeast component in the flora performs important functions in the human body. However, an overgrowth of *Candida albicans* results from an imbalance in the body's normal flora. The term is Candidiasis or Thrush. Most common way to treat this condition is by using Nystatin solution. According to new studies, probiotic solutions can be used to reduce the number of *Candida albicans* adherence and thereby treat Candidiasis or Thrush. We aim to discuss the actual role of probiotic solutions in oral cavity and treatment of Candidiasis.
