Quick answer
You should soak your dentures overnight in plain water or a dentist-recommended denture cleaning solution. This keeps dentures moist, helps remove bacteria and prevents warping or discomfort. Avoid hot water, bleach, vinegar or mouthwash, as these can damage denture materials.
In this guide, we explain the best liquids to soak dentures in, what you should avoid, and how to care for different types of dentures, including acrylic, cobalt chrome and flexible Valplast dentures.
Why Should Dentures Be Soaked Overnight?
Dentures are designed to stay moist. Leaving them out overnight without soaking can cause them to dry out, lose their shape and feel uncomfortable when worn again.
Soaking dentures overnight helps to:
- Maintain their shape and fit
- Reduce bacteria and odours
- Give your gums time to rest
For most patients, removing dentures at night supports long-term oral health.
What Is the Best Thing to Soak Dentures in at Night?
Plain water
For many denture wearers, cool or room-temperature water is a safe and effective option. It keeps dentures hydrated and is suitable for all materials. Dentures should always be fully submerged, and hot water should never be used, as it can cause warping.
Denture cleaning solutions or tablets
Specialist denture cleaning products are widely recommended. They help remove bacteria, reduce staining and keep dentures fresh. Some are designed for daily use, while others are intended for occasional deep cleaning, so it is important to follow the instructions provided.
Water with a denture cleaner
Many patients follow a simple routine of brushing dentures before bed, soaking them overnight in water with a denture tablet, then rinsing thoroughly before wearing them again in the morning. This provides effective cleaning without damaging the denture.
What Should You Avoid Soaking Dentures In?
Some products can damage dentures or irritate your mouth and should be avoided. These include hot water, bleach, vinegar and alcohol-based mouthwash. Using the wrong solutions can lead to discolouration, weakened materials and poor denture fit over time.
Does the Type of Denture Affect Overnight Soaking?
Yes. Denture material plays a role in how they should be cared for.
Acrylic dentures should always be kept moist and are suitable for soaking overnight in water or a denture solution. Cobalt chrome dentures are stronger but still benefit from soaking to help reduce plaque build-up around metal components. Flexible Valplast dentures must never be allowed to dry out, as this can affect their flexibility and comfort.
If you are unsure which method is best for your dentures, your dentist can provide tailored advice.
Should You Wear Dentures Overnight?
In most cases, dentures should be removed at night. Sleeping without dentures helps reduce the risk of denture-related infections, improves gum health and allows oral tissues to recover from daily pressure. Some patients may be advised to wear dentures overnight temporarily, but this should always be guided by a dentist.
How to Clean Dentures Before Soaking
Before placing dentures in water overnight, they should be gently cleaned. Rinse them under running water, brush carefully with a denture brush and avoid abrasive toothpaste. This helps prevent bacteria from sitting on the denture surface while soaking.
