Appliance hygiene

How clean is your appliance really?

Your retainers may look clean but you can’t always see what is lurking in the hidden areas that brushing and tablets simply cannot reach.

Odour

From trapped food & debris

Biofilm

Which traps bacteria

Staining

From everyday wear

Bacteria

That multiplies the longer it’s left

Science backed, proven results

Better than Traditional Cleaning

Most cleaning methods solve one part of the problem.

Water Rinsing

  • Removes loose debris
  • Doesn’t reach crevices
  • Doesn’t reduce bacteria

Brushing

  • Removes surface debris
  • Can scratch appliances
  • Limited reach

Cleaning Tablets

  • Helps remove odour
  • Limited stain removal
  • Doesn’t remove biofilm

Ultrasonic Cleaning

  • Deep cavitation cleaning
  • Reaches areas brushing can’t
  • Limited bacteria reduction
Clear Winner

Ultrasonic + UV-C

  • Deep cavitation cleaning
  • Cleans difficult areas
  • 99.9% Bacteria Reduction

We combine two technologies for one cleaner routine.

The Sonic Pro (and Sonic Odyssey) combines ultrasonic cleaning with independently tested UVC technology for a more complete approach to appliance hygiene.

  • Powerful ultrasonic cavitation

    cleans deep into gaps and crevices

  • Independently tested UV-C technology

    99.9% bacterial reduction*

*Based on comparative bacteria-removal testing using selected appliance-cleaning methods.

Ultrasonic waves lift the debris

Ultrasonic waves lift the debris

Ultrasonic Waves fill the water with millions of microscopic bubbles. They collapse against every surface of your appliance - including the ones a brush will never touch, and lift debris away.
UV-C Light destroys bacteria

UV-C Light destroys bacteria

UV-C Light deals with the bacteria that cleaning alone leaves behind. No chemicals, nothing to rinse off.

Research

Peer-reviewed research. Explained simply.

We review the latest independent studies so you don’t have to. Here’s what peer-reviewed research tells us about ultrasonic cleaning for different removable dental appliances.

Peer reviewed study

Clear Aligners

Ultrasonic cleaning significantly improved biofilm removal from clear aligners compared to traditional cleaning

Clear Aligners

Key findings

  • 42 kHz ultrasound combined with a germicidal agent was the most effective method tested.
  • The combined approach significantly outperformed the other cleaning strategies for biofilm removal.
  • The study supports combining ultrasonic cleaning with an antimicrobial step.
Peer reviewed study

Clear Aligners

Peer-Reviewed Comparative Study

Researchers compared nine different cleaning methods on clear aligners worn by orthodontic patients, with results assessed using scanning electron microscopy.

The standout result was 42 kHz ultrasonic cleaning combined with a germicidal agent, which was the only method found to be statistically effective at removing bacterial biofilm from the aligner surface.

Why this is relevant to Sonic Dental: The Sonic Pro operates at 42 kHz and combines ultrasonic cleaning with an antimicrobial UVC step, reflecting the dual-mechanism cleaning principle supported by this research.

Key takeaway

The study supports combining 42 kHz ultrasonic cleaning with an antimicrobial step for effective aligner cleaning.

Clinical study

Orthodontic Retainers

Ultrasonic cleaning reduced microbial contamination more effectively than conventional cleaning

Orthodontic Retainers

Key findings

  • Ultrasonic cleaning with water or chemical agents significantly reduced total microbial load.
  • Fewer surface scratches and better colour stability compared with brushing.
  • Effective, safe and suitable for everyday at-home use.
Clinical study

Orthodontic Retainers

Clinical Study

This clinical study compared four cleaning methods on thermoplastic orthodontic retainers, including brushing, ultrasonic cleaning with water and ultrasonic cleaning with an antimicrobial solution.

Ultrasonic cleaning combined with chlorhexidine produced the lowest microbial contamination of the methods tested. Researchers also found no significant adverse changes in colour, surface roughness or microhardness, while microscopy showed fewer surface scratches in ultrasonically cleaned retainers.

Why this is relevant to Sonic Dental: The findings support the use of ultrasonic technology for cleaning orthodontic retainers, one of the primary applications of Sonic Dental cleaners.

Key takeaway

Combining ultrasonic cleaning with an antimicrobial agent provided the strongest microbial cleaning performance in the study.

Randomised clinical trial

Dentures

Randomised trials demonstrate improved denture cleanliness and patient satisfaction using ultrasonic cleaning

Dentures

Key findings

  • Ultrasonic cleaning with denture-cleaning solution significantly improved cleanliness compared with conventional cleaning.
  • Patient satisfaction improved significantly more with the ultrasonic approach.
  • The trial supports combining ultrasonic cleaning with a denture-cleaning solution for everyday hygiene.
Randomised clinical trial

Dentures

Randomised Clinical Trial

This randomised crossover clinical trial involving 56 denture wearers compared an ultrasonic cleaner used with denture-cleaning solution against conventional brushing with denture-cleaning solution.

Ultrasonic cleaning produced significantly greater improvements in denture cleanliness and patient satisfaction than conventional cleaning.

Why this is relevant to Sonic Dental: The trial provides clinical evidence supporting ultrasonic cleaning for removable dentures, which can be cleaned using Sonic Dental ultrasonic cleaners.

Key takeaway

The trial supports ultrasonic cleaning as an effective approach to everyday denture hygiene.
