Oral Hygiene Practices for Preventing Oral Thrush

Good oral hygiene practices are essential in preventing oral thrush, also known as oral candidiasis, which is primarily caused by the overgrowth of Candida species, particularly Candida albicans. Here are some evidence-based strategies to maintain good oral hygiene and prevent oral thrush.
- Regular Brushing and Flossing: Brush teeth at least twice daily with fluoride toothpaste and floss daily to remove dental plaque, which can harbor Candida. The American Dental Association emphasizes the importance of effective plaque removal and regular dental visits to promote oral health.[1]
- Use of Antimicrobial Mouthwashes: Mouthwashes containing chlorhexidine digluconate or cetylpyridinium chloride have been shown to impair the virulent traits of Candida albicans and other oral pathogens, thus helping to maintain microbial homeostasis in the oral cavity. However, chlorhexidine should be used with caution due to potential side effects.[2]
- Maintain Salivary Flow: Adequate salivary flow is crucial as saliva has antifungal properties. Patients with dry mouth (xerostomia) should use mechanical salivary stimulants, oral moisturizers, or systemic medications to promote saliva to manage dry mouth and reduce the risk of oral candidiasis. The American Dental Association recommends these measures for managing xerostomia and preventing candidiasis.[3]
- Proper Denture Hygiene: For denture wearers, it is important to clean dentures daily and remove them at night. Disinfecting dentures with solutions such as 2% chlorhexidine gluconate can prevent reinfection. Denture stomatitis, a form of oral candidiasis, is often associated with poor denture hygiene. [4-5]
- Avoiding Risk Factors: Minimize the use of broad-spectrum antibiotics and corticosteroids, which can disrupt the normal oral microbiota and promote fungal overgrowth. Patients should also avoid high-sugar diets and smoking, as these can increase the risk of oral candidiasis.[6]
- Regular Dental Check-ups: Regular dental visits are essential for early detection and management of oral conditions that may predispose to candidiasis. Dentists can provide professional cleaning and tailored advice on maintaining oral hygiene.[1]
By adhering to these practices, individuals can significantly reduce their risk of developing oral thrush and maintain overall oral health.
