Denture cleaning is very important to maintain good oral health for denture wearers. Denture wearers should stick to daily brushing and denture cleansing to remove microorganisms surrounding the dentures, according to a study published in Gerodontology in 2012. However, effective denture cleaning requires some research and practice.
In this post, we are explaining the best cleaning methods to maximize denture cleaning. The article handles the issue theoretically and practically in a very simplified way so that you can make the most of it, reconsider how you clean your dentures, and make critical adjustments or changes where necessary. Note that, you should always see your dentist for the best treatment or practice for you.

Why Is It Important To Clean Your Dentures?
Maintaining proper denture hygiene is crucial for preventing oral infections, ensuring functionality, and extending the lifespan of your dentures. A 2022 study published in the British Dental Journal emphasizes that inadequate denture care can lead to dental caries, periodontal disease, and oral candidosis.
Regular cleaning of dentures offers several significant benefits:
- Prevents Oral Infections: Regular cleaning reduces the risk of infections such as dental stomatitis and yeast infections by removing food particles and bacteria.
- Enhances Functionality and Longevity: Proper maintenance ensures that dentures remain functional and durable over time.
- Promotes Overall Oral Hygiene: Clean dentures contribute to fresh breath and overall oral health, boosting self-confidence.
Incorporating both mechanical and chemical cleaning methods tailored to the individual’s needs is recommended for optimal denture hygiene.
Keeping your dentures clean is crucial for maintaining both your oral health and the longevity of your dentures. While daily cleaning at home is essential, regular check-ups and professional cleanings are also important. Our clinic offers comprehensive denture care services if you are looking for expert advice or considering dentures.
What Are The Different Types Of Denture Cleaning Methods?
There are 2 main denture cleaning methods, which are mechanical and chemical, and each has its subtypes:
Mechanical methods
- Manual cleaning
- Vibration-based cleaning baths
Chemical methods
- Bleach based
- Effervescent type
- Mineral acid based
- Enzyme-based cleaners
- Oral rinses
- Flexible denture cleaners

Let’s go over each of these denture cleaning methods briefly;
Mechanical Methods
Mechanical methods include manual cleaning and vibration-based cleaning baths. Manual cleaning can be performed using one or more of the following agents:
- Denture toothpaste (denture cleaning paste)
- Denture cleaning gel
- Denture cleaning foam
- Denture cleaning powder
As for the vibration-based cleaning baths, there are two ways to go. They are:
- Ultrasonic cleaning bath, with a frequency range between 20 kHz and 60 kHz.
- Sonic Cleaning bath, with a frequency less than 10 kHz.
Chemical Methods
Chemical denture cleaning methods involve various chemicals and modes of action.
Bleach-based cleansers include %1,5 to %2 sodium hypochlorite or sodium hydroxide. The agents get activated in water and, dissolve microbial cells mucins, and degrade fatty acids.
Effervescent-type cleansers contain one or more of the following oxidants, leaving carbon dioxide or oxygen bubbles on the denture surface to facilitate cleaning.
- Peroxide
- Bicarbonate
- Percarbonate
- Persulphate
Mineral acid-based cleansers contain phosphoric or hydrochloric acids. The mineral content in this type of cleanser dissolves the cell membranes and biofilm deposits.
Enzyme-based cleaners are similar to effervescent-type cleaners but contain additional enzymes, including proteases, amylases, and lipases.
Oral rinses refer to any mouthwash product. They are effective thanks to the chlorhexidine content. The concentration ratio varies between 0,2% and 4%. The higher the concentration, the better hygiene dentures get. However, prolonged use of oral rinses can stain the denture as well as natural teeth.
Flexible denture cleaners are special toothbrushes with silicone bristles and denture special flexible denture cleaners. The formulation of flexible denture cleaners is similar to effervescent type cleansers in which antioxidants help remove the microorganisms on the denture.

How to Clean Dentures Made of Different Materials?
Different denture material types require different considerations and, thus, techniques and materials. Here are short instructions on how to clean common denture types:
Metallic Dentures
Manual cleaning using denture brushes and creams is good for metallic dentures as they are less vulnerable to the risk of damage. However, avoid acid or bleach-based cleaners that might corrode the denture surface. Although some types of metal dentures are resistant to chemicals, you should still ask your dentist before opting for a chemical cleaning.

Acrylic Dentures
Use a soft-bristled denture brush and a non-abrasive denture cleaner. Avoid using regular toothpaste, as it can be too abrasive and scratch the surface of your dentures. If you use denture adhesive, make sure to thoroughly clean any residue from your dentures and gums. For more detailed advice on adhesive use, check out our Denture Adhesive Guide.

Polymer Dentures
Manufacturers of polymer-based dentures (aryl ketone polymer-based dentures) report that this type of denture is compatible with all types of denture cleaning methods and denture cleaning products. However, there is not enough research testing their compatibility. Therefore, you are advised to follow the manufacturer’s instructions.
Flexible Dentures
Flexible dentures are made from thermoplastic polyamide resins, and they are resistant to cleaning agents and solvents. However, flexible denture manufacturers promote their cleaning products rather than using any cleanser randomly.
Here is a table illustrating denture types and required cleaning techniques.
