How to clean Invisalign aligners: what works and what to avoid

Cleaning Invisalign aligners properly helps prevent stains, odour, and bacterial build-up. Start by rinsing your trays immediately after removal. Use a soft toothbrush (not the one for your teeth) and a clear, unscented liquid soap to gently clean all surfaces. Rinse thoroughly with cool water. Avoid toothpaste, coloured soaps, and hot water, as these can damage or discolour the aligners. Consistent cleaning keeps your trays clear and odour-free. cost of Invisalign treatment in Nigeria

• No toothpaste or mouthwash with dyes.
• Avoid harsh chemicals or bleach.

Can you clean Invisalign aligners with baking soda or toothpaste?

Baking soda is mildly abrasive and can scratch aligners if used directly. If needed, dissolve a small amount in water for a gentle soak, but avoid scrubbing.

• Never use toothpaste on trays.

• Avoid harsh chemicals or bleach.

• Avoid sugary drinks or snacks with trays in.
• Store trays in a cool, dry case.

When to see your dentist about Invisalign aligner care

If you notice stubborn stains, odour that doesn’t resolve, or damage to your aligners, book a review with your dentist. Sometimes professional cleaning or a replacement tray is needed.
