If you are wondering how to clean dentures naturally, the most effective and safe options include soaking them in a mild saltwater solution, brushing with baking soda, or using vinegar diluted with water. These chemical-free methods help remove bacteria, plaque, and stains while keeping your dentures fresh without harsh cleaners.
In this blog, we explain the best natural denture cleaning methods, step-by-step guides for safe use, and expert advice from Revesby Dental Centre. You will also learn what to avoid, how often to use natural cleaners, and when professional dental care is necessary.
Why Choose Natural Denture Cleaning Methods?
Many patients prefer natural denture care because it avoids harsh chemicals while still keeping dentures hygienic. Reasons include:
- Gentle on dentures – avoids long-term wear from abrasive products
- Budget-friendly – uses common household items
- Safe for sensitive mouths – less risk of irritation compared to strong cleansers
- Eco-friendly – reduces reliance on chemical-based products
That said, while natural methods are effective for daily freshness, they should complement not replace professional dental cleansers and check-ups.
Best Natural Denture Cleaning Methods
1. Baking Soda
Baking soda is one of the most popular homemade denture cleaners. Its mild abrasive properties help remove stains and neutralise odours.
How to use baking soda for dentures:
1. Dissolve one teaspoon of baking soda in a glass of warm water.
2. Soak dentures for 15–30 minutes.
3. Rinse thoroughly before wearing.
Benefits:
- Natural deodoriser
- Gentle stain removal
- Readily available in all Australian supermarkets
2. Saltwater Soak
A simple saltwater soak is effective for killing bacteria and keeping dentures moist.
How to prepare:
1. Mix half a teaspoon of salt in a glass of lukewarm water.
2. Soak dentures for 15–30 minutes.
3. Rinse well before use.
Benefits:
- Safe and natural antibacterial option
- Reduces odour and plaque
- Budget-friendly and easy to prepare
3. Vinegar Solution
White vinegar is a natural disinfectant. When diluted correctly, it can help remove tartar build-up.
How to prepare:
1. Mix equal parts white vinegar and water.
2. Soak dentures for up to 30 minutes.
3. Rinse thoroughly to remove vinegar taste.
Important note:
Avoid vinegar if your dentures have metal clasps, as it may cause corrosion.
4. Lemon Juice Soak (Occasional Use)
Lemon juice has natural bleaching properties, which can help brighten dentures.
How to use:
1. Mix two tablespoons of lemon juice in a glass of water.
2. Soak dentures for no more than 20 minutes.
3. Rinse thoroughly before use.
Caution: Overuse may weaken denture material, so this should be done occasionally, not daily.
5. Herbal Cleaning (Clove Oil or Tea Tree Oil)
Some natural oils have antibacterial and antifungal properties.
How to use:
1. Add 1–2 drops of clove or tea tree oil into a glass of water.
2. Soak dentures briefly (10–15 minutes).
3. Rinse thoroughly to avoid lingering taste.
Note: Always dilute essential oils; never apply them directly to dentures or gums.
Step-by-Step: Daily Natural Cleaning Routine

2. Brush gently with a soft denture brush and warm water. Avoid toothpaste.
3. Soak in a natural solution (saltwater, baking soda, or diluted vinegar).

Can I Clean Dentures Without Chemicals Every Day?

- Applying regular toothpaste, which is too abrasive
- Soaking in undiluted vinegar or lemon juice, which may damage dentures
