Keeping your dental retainers clean and hygienic is crucial for oral health, and making your own retainer cleaning tablets can be a fun and effective DIY project. These homemade tablets ensure that your retainers stay sparkling and fresh and give you control over the ingredients used, ensuring that they are safe and natural.

Creating your own retainer cleaning tablets is an economical and eco-friendly solution for dental care. Using available ingredients, these homemade tablets ensure you can keep up with your dental hygiene effectively and safely with simple ingredients that are easy to find.

The natural composition of the tablets is kinder to the environment, and the infusion of your preferred essential oil adds a refreshing scent, leaving your retainers smelling pleasant and feeling thoroughly clean.


Like commercial retainer cleaners, these DIY tablets rely on effervescence, abrasion, and surfactant action to deeply cleanse the retainers. When you drop a tablet into the water with your retainer, the fizzing action immediately begins, indicating the release of cleaning agents. This effervescence ensures that the active ingredients are distributed evenly throughout the retainer, offering a comprehensive clean.

The surfactants work to break down and wash away residues, while the mild abrasives gently scrub the surface without damaging it. The result? A retainer that's as clean and fresh as any commercial product would offer but with the added peace of mind from using natural, safe ingredients.


Let's explore how each ingredient contributes to the efficacy of these tablets.

Baking soda is a gentle abrasive that effectively scrubs plaque and stains from your retainers. Its alkaline nature helps to neutralize acidic bacterial byproducts, reducing the likelihood of bad odors. Additionally, baking soda is known for its natural whitening properties, helping restore your retainers' original clarity.

Baking soda is a natural deodorizer. It helps to neutralize and remove unpleasant odors from the retainer

Citric Acid is a natural acid that is crucial in our homemade retainer cleaner. When it reacts with baking soda in water, it fizzes and creates an effervescent action that helps to dislodge food particles and debris from the retainer. This effervescence ensures a thorough cleaning, reaching even the hard-to-clean nooks and crannies.

When baking soda and citric acid are mixed and then come into contact with water, they react to create an effervescent or fizzing action. This fizzing helps to dislodge and break down debris, plaque, and bacteria from the surfaces of the retainer.

The bubbling action ensures that the cleaning agents penetrate even the hard-to-reach areas of the retainer.

The reaction between the acidic citric acid and the basic baking soda ultimately results in a neutral solution. This is gentle on the retainer material and safe for oral appliances, as it doesn't leave behind any harmful residues.


SCS derived from coconut oil, Sodium Coco Sulfate acts as a surfactant in our cleaning tablets. It lowers the surface tension of water, enabling it to penetrate and lift away grease, saliva residues, and build-up from the retainer. This ingredient ensures that your retainer is not just visually clean but also hygienically clean.

Cristal Soda also known as Sodium Carbonate, is a water softener in our DIY tablets. It helps remove mineral build-ups, which is common if you're using tap water to rinse your retainers. This ensures that your retainers don't develop those cloudy deposits over time.

Adding essential oil, such as grapefruit or lemon, not only imparts a pleasant aroma to your cleaning tablets but also brings its benefits. Many essential oils have antibacterial properties, providing an extra layer of hygiene and a refreshing aftertaste.


  1. Add all the powders to a wide container.




  1. Add the essential oil and mix everything to combine.




  1. Spray the mixture with a spray bottle (filled with distilled water) to achieve a sandy, moist texture.



  1. Once the mixture is moist, you can stick it together when you press it with your hands; it's time to make the tablets.


  1. Press the mixture into a cavity mold (or ice cube tray), or use a measuring spoon and press the mixture into the spoon. Pressing hard enough to ensure the mixture sticks to form a tablet is important. If you are using a measuring spoon - after pressing into the spoon, tap the spoon onto the surface and release the tablet. If you use a silicone mold or ice cubes tray, press the mixture into the mold and leave it to set for an hour or more.












  1. After removing the tablets from the mold (or after making some tablets with a measuring spoon), let them dry for 5-7 hours before storing them.



  1. To use the tablets: Place one tablet in a glass or a bowl full of water. Put your retainers in, and leave them for 3-6 minutes. Then, clean with a toothbrush and rinse with water.






  1. The tablets are for cleaning retainers only! Don't consume them, and keep them away from kids and pets.
