Oral candidiasis is one of the most common diseases affecting the oral mucosa. The most common cause of fungal infections of the oral cavity are Candida fungi. They have the role of commensals in humans, but in the elderly population with frequent chronic diseases, immunocompromised patients and people who wear mobile dentures, they can switch from the role of commensals to the role of parasites. Prosthetic stomatitis is a frequent change that occurs with pronounced clinical changes in most people with partial and total dentures. Long-term tissue trauma due to poorly made dentures, inadequate oral hygiene, continous wearing of dentures, smoking and diabetes are just some of the predisposing factors for the onset of the disease. In addition, it is very important to approach the therapy adequately and on time so that the disease does not progress. The most commonly used antifungal drugs are azoles and polyenes, which is also a problem because their use has resulted in resistance over many years. Because of this, clinicians have resorted to other methods of treating fungal infections of the oral cavity, where plant extracts have proven to be very effective. Olive, propolis, mint, rosemary, palm tree and marjoram extracts are just some of the available natural remedies that have shown exceptional effectiveness in the treatment of oral infections.
