How To Clean & Store Your Dentures Overnight

(for Clients from Perth to Carleton Place)

Step-by-Step Evening Cleaning Routine

  1. Remove Your Dentures Carefully
    Always take them out over a soft towel or a basin of water to avoid cracks from accidental drops.
  2. Rinse Under Lukewarm Water
    Gently rinse off food debris. Avoid hot or boiling water, it can warp acrylic bases.
  3. Brush Gently with a Soft-Bristle Brush
    Use a denture brush or very soft toothbrush plus a non-abrasive denture cleanser or mild soap. Avoid standard toothpaste, it’s too abrasive for acrylic surfaces.
    Pay special attention to the surface that contacts your gums, crevices, and underside.
  4. Soak Overnight in a Suitable Solution
    Place your dentures in water or a denture-safe soaking solution overnight. This keeps them moist and helps prevent warping.
    • Use a commercial denture cleanser (effervescent tablets) a few times per week for deeper cleaning.
    • Never soak in bleach, harsh chemicals, or hot water, which degrade materials.
  5. Rinse Before Reinserting
    In the morning, thoroughly rinse off the soaking solution before placing dentures back in your mouth.

🏺 Best Practices for Overnight Storage

  • Always keep dentures submerged or in a sealed moist environment—never let them dry out completely. Dry acrylic can crack or deform.
  • Use a proper denture soaking cup with a lid to minimize contamination and reduce odor (see image suggestions).
  • Clean the soaking container regularly to prevent bacteria buildup.
  • Avoid storing dentures in direct sunlight or extreme heat—these conditions may warp them.

📌 Why Overnight Care Matters (Especially Locally)

In regions like Perth ON or Carleton Place, your dentures are exposed to temperature shifts, indoor heating, and potential dryness. Keeping your prosthetics hydrated overnight helps them maintain shape, reduces microbial growth, and supports comfort when you wear them during the day. According to the ADA, storing dentures in water or solution when not in use helps them retain shape and prevents drying out.

Also, consistent cleaning helps avoid denture-related issues like stomatitis or irritation, which can arise from bacterial or fungal buildup.
