Always rinse your aligners (never use hot water) every time you remove them from your mouth to prevent the build-up of bacteria from your saliva. Using hot water can deform your SPARK aligners™.
Never use toothpaste and a hard-bristled toothbrush to clean your SPARK aligners. They may scratch your aligners, causing them to appear cloudy and prone to bacteria build-up.
Avoid soaking your aligners in mouthwash to prevent any discolorations.
And lastly, always put your SPARK™ aligners in their case when you remove them before eating and drinking to prevent getting lost or damaged.
