Starting your journey toward a straighter smile is exciting! If you are using clear aligners in Sunnyvale, maintaining those trays is the secret to a fast, healthy, and "invisible" transformation.
At Mint Dental Care, we want your treatment to be as seamless as possible. If you don’t clean your aligners properly, they can become cloudy, trap bacteria against your teeth, or even develop an unpleasant odor.
Here is everything you need to know about taking care of your clear aligners to ensure your best results.
1. Rinse Every Time You Remove Them
Whenever you take your trays out, whether it’s for a meal at downtown Sunnyvale’s Murphy Avenue or just a quick snack, give them a rinse immediately.
- This prevents saliva and plaque from drying on the plastic, which creates a film that is much harder to remove later.
- Tip: Use lukewarm water. Never use hot water, as it can warp the medical-grade plastic and ruin the fit of your aligners.
2. Brush and Floss Your Teeth Before Reinserting
This is the most important rule of aligner hygiene. If you put your trays back in after eating without flossing and brushing, you are trapping food particles and sugars against your enamel.
- This is a recipe for cavities and tooth discoloration.
- Tip: Keep a small travel kit with a toothbrush and floss in your bag so you’re always prepared when dining out in Silicon Valley.
3. Clean Your Aligners Daily (The Right Way)
Rinsing isn't enough; you need to clean your clear aligners at least once a day.
- Use a Soft Toothbrush: Use a separate soft-bristled brush just for your trays.
- Avoid Toothpaste: Most toothpastes are abrasive and can create microscopic scratches in the plastic, which give bacteria a place to hide.
- The Best Cleanser: Use a clear, unscented antibacterial soap or specialized aligner cleaning tablets.
4. The Daily Soak
To keep your aligners crystal clear, we recommend a daily soak. You can use:
- A 50/50 mix of white vinegar and water (rinse thoroughly after!)
- Retainer cleaning tablets
A 15-minute soak while you eat dinner is usually all it takes to keep them looking brand new.
5. Store Them Safely
"If they aren't in your face, they're in the case."
Never wrap your aligners in a napkin while eating. This is the most common way patients accidentally throw their trays in the trash. Always place them in their protective case to keep them safe from bacteria and accidental loss or damage.
