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 both theoretically and practically in a very simplified way so that you can make the most of it, reconsider the way you clean your dentures, and make critical adjustments or changes where necessary.

Why Is It Important To Clean Your Dentures?

Proper denture hygiene is of critical importance in several aspects such as oral infection, functionality, and longevity. There is a significant relationship between dental stomatitis or yeast and denture hygiene, according to a study published in the Journal of Dental Rehabilitation, in 2002. However, the importance of denture cleaning is not limited to that. Here is a list of some of the most significant benefits of denture cleaning:

– It prevents oral infections and related diseases by removing food particles and bacteria.

– It increases the functionality and longevity of the dentures.

– It ensures overall oral hygiene and fresh breath, which translates into self-confidence.

What Are The Different Types Of Denture Cleaning Methods?

There are 2 main denture cleaning methods, 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, and mucins as well as 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 they also 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

Acrylic-based dentures are the most common denture types prescribed by dentists. Typical toothbrushes might scratch the denture surface, therefore make sure your brush is a soft-bristled one. You should avoid regular toothpaste and bleach-based chemicals for acrylic denture cleaning. However, special denture toothpastes are suitable for acrylic dentures as they do not contain abrasive ingredients.

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.
