Can I Soak My Dentures In Mouthwash Overnight?

Maintaining proper denture care is essential for oral health and overall well-being. While denture cleansers are specifically designed to clean dentures, some individuals may wonder if soaking their dentures in mouthwash overnight is an effective alternative. This article delves into the safety and efficacy of using mouthwash for denture soaking.

Can You Soak Dentures in Mouthwash Overnight?

Soaking dentures in mouthwash overnight is generally considered safe and can provide some level of cleaning and disinfection. Mouthwash contains antibacterial and antifungal agents that can help eliminate odor-causing bacteria and prevent fungal growth on dentures. However, it’s important to note that mouthwash is not a substitute for regular denture cleansing.

Benefits of Soaking Dentures in Mouthwash

Soaking dentures in mouthwash can offer several benefits, including:

  • Odor Control: Mouthwash can help eliminate unpleasant odors caused by bacteria buildup on dentures.

  • Germicidal Action: The antibacterial agents in mouthwash can help reduce the risk of oral infections and promote oral hygiene.

  • Convenience: Soaking dentures in mouthwash overnight is a convenient way to clean and disinfect them while you sleep.

Limitations of Soaking Dentures in Mouthwash

While soaking dentures in mouthwash can be beneficial, it’s important to recognize its limitations:

  • Incomplete Cleaning: Mouthwash alone may not effectively remove all food debris, plaque, and tartar buildup from dentures, requiring regular cleansing with denture-specific products.

  • Potential Damage: Certain types of mouthwash, particularly those containing alcohol or harsh abrasives, may damage the acrylic material of dentures over time.

  • Reduced Effectiveness: Prolonged soaking in mouthwash may reduce the effectiveness of the germicidal agents, making it less effective in combating bacterial growth.

Recommended Practice for Denture Soaking

For optimal denture care, it’s recommended to follow a two-step process:

  1. Regular Denture Cleansing: Use a denture cleanser specifically designed to remove plaque, tartar, and food debris from dentures. Follow the instructions on the product carefully to avoid damaging the dentures.

  2. Occasional Mouthwash Soaking: After regular cleansing, consider soaking your dentures in mouthwash overnight for added odor control and germicidal action. Dilute the mouthwash with equal parts water to minimize any potential damage to the dentures.


Soaking dentures in mouthwash overnight can be a safe and convenient way to maintain denture hygiene and prevent odor-causing bacteria. However, it’s crucial to use a denture cleanser regularly for thorough cleaning and to dilute mouthwash when soaking to prevent denture damage.
