If you’ve chosen Invisalign clear aligners to straighten your teeth, you’re already taking a positive step toward a healthier, more confident smile. Invisalign is known for being discreet and comfortable compared to traditional braces. To keep those aligners truly invisible and hygienic, however, daily care is essential.
At Bexley Dental, we know patients appreciate the freedom Invisalign provides, the ability to remove aligners for eating, brushing, and special occasions. That flexibility comes with one important responsibility: consistent maintenance. Proper cleaning keeps your aligners clear, odour-free, and effective throughout treatment.
Here are some simple maintenance tips recommended by the Bexley Dental team to help you get the best results from your Invisalign journey.
1. Rinse Your Aligners Every Time You Remove Them
Whenever you take out your aligners, whether to eat, drink, or brush your teeth, rinse them under lukewarm water. This prevents saliva and plaque from drying on the surface, which can cause cloudiness and odour.
Pro tip: Avoid hot water, which can warp the medical-grade plastic and affect fit.
2. Brush and Floss Before Reinserting Your Aligners
Your aligners fit closely over your teeth, so food debris or plaque left behind can become trapped against the enamel. Always brush and floss before putting your aligners back in:
- Brush gently with a soft-bristled toothbrush and fluoride toothpaste.
- Floss or use an interdental brush to remove debris.
- Rinse thoroughly before reinserting.
This helps maintain oral hygiene and keeps your aligners clearer for longer.
3. Use a Gentle Cleaning Solution (Not Toothpaste)
Most toothpastes are abrasive and can scratch aligners, creating cloudy spots that trap bacteria. Instead, clean your Invisalign clear aligners with one of these safer methods:
- Mild antibacterial soap: Add a few drops to lukewarm water and gently brush with a soft toothbrush.
- Invisalign Cleaning Crystals: Commonly used to help remove plaque and odour, follow manufacturer instructions or ask your dentist which product suits you best.
- White vinegar rinse: Some patients use a 1:3 vinegar-to-water soak for 15–20 minutes; check with your dentist first to confirm suitability.
Perform a deep clean once daily to maintain clarity and freshness.
4. Store Aligners Safely in Their Case
When you’re not wearing your aligners, place them immediately into their protective case. Leaving them exposed can attract bacteria or lead to accidental loss. Carry your case with you so your aligners stay clean and secure wherever you are.
5. Avoid Eating or Drinking (Except Water) with Aligners In
Remove your aligners before eating or drinking anything other than water.
- Coloured drinks such as coffee, tea, or wine may stain them.
- Sugary drinks can trap residue between teeth and trays.
- Hot liquids may distort the aligner shape.
If in doubt, take them out, rinse your mouth, and then replace them.
6. Keep a Travel-Size Cleaning Kit Handy
Maintain good hygiene on the go with a small “Invisalign care kit” containing:
- Travel toothbrush and toothpaste
- Dental floss or floss picks
- A small bottle of mouth rinse
- Your aligner case
This simple kit helps you care for your aligners at work, school, or while travelling.
7. Handle Aligners with Clean, Dry Hands
Always wash your hands thoroughly before handling your aligners. Oils, lotions, or germs can transfer to the trays and into your mouth. Dry your hands before touching the aligners to prevent slipping or damage.
8. Stick to the Replacement Schedule
Each aligner set is typically worn for about one to two weeks, depending on your dentist’s instructions. Avoid extending wear time to “save” trays, as they can lose effectiveness and accumulate bacteria.
If an aligner breaks or is lost, stop wearing it and contact your dental practice as soon as possible. Your dentist will advise the next steps, such as moving to the next tray or arranging a replacement.
9. Keep Up with Your Dental Check-Ups
Regular check-ups help monitor your progress and ensure your treatment remains safe and effective. During visits, your dentist can:
- Check aligner fit and cleanliness
- Assess tooth movement
- Provide professional cleaning or adjustments if required
Consistent follow-up helps keep your Invisalign treatment on track.
10. Don’t Forget to Clean Your Aligner Case
Your aligner case can collect bacteria over time. Wash it daily with warm, soapy water and allow it to air-dry completely. This helps prevent contamination when your aligners are stored.
