Daily Cleaning Routine for Invisalign
A consistent daily cleaning habit keeps your aligners clear, odor-free, and hygienic. You should clean your aligners every morning, every night, and ideally each time you remove them to eat.
Rinse Every Time You Remove Them
Each time you take out your aligners, rinse them under cool or lukewarm running water. This removes saliva and loose plaque before they dry on the surface. Dried saliva creates a cloudy, white film that is harder to remove later. Get into the habit of rinsing immediately rather than setting the aligners down dry.
Brush Gently with Clear Soap
At least twice a day, brush your aligners gently using a soft-bristled toothbrush and a small drop of clear, unscented liquid hand soap or dish soap. Brush all surfaces, inside and out, using light circular motions. Rinse thoroughly afterward to remove all soap residue. Avoid using colored or scented soaps, as these can leave residue or flavor on the aligners.
Why You Should Not Use Toothpaste
Most toothpastes contain mild abrasives designed to scrub stains off tooth enamel. These abrasives scratch the smooth surface of Invisalign plastic, creating tiny grooves that trap bacteria and make the aligners look cloudy or frosted. Whitening toothpastes are especially problematic because they contain stronger abrasives. Stick to clear liquid soap for brushing your aligners.
Soaking Your Aligners: What Works and What to Avoid
Daily soaking in a cleaning solution helps remove bacteria, mineral deposits, and odor that brushing alone may not eliminate. Several products work well, and a few common ones should be avoided.
Invisalign Cleaning Crystals
Invisalign sells its own cleaning crystals designed specifically for their aligners. Dissolve one packet in lukewarm water and soak the aligners for 15 to 30 minutes. These crystals effectively remove buildup without damaging the plastic. They are convenient but more expensive per use than some alternatives.
Retainer and Denture Cleaning Tablets
Over-the-counter retainer cleaning tablets or denture cleaning tablets (like Retainer Brite or generic denture cleaners) are an effective and budget-friendly alternative to Invisalign-brand crystals. Drop one tablet in lukewarm water, add your aligners, and soak for the time recommended on the packaging, typically 15 to 30 minutes. Rinse the aligners thoroughly before putting them back in your mouth.
What Not to Soak Your Aligners In
- Colored mouthwash: Blue, green, or purple mouthwashes stain aligners. Even clear mouthwash may contain alcohol that can cloud or degrade the plastic over time.
- Hot or boiling water: Heat warps Invisalign plastic. Even water that is uncomfortably hot to the touch can distort the shape enough to change the fit.
- Bleach or undiluted hydrogen peroxide: These are too harsh and can weaken, whiten, or degrade the aligner material.
- Scented soaps or antibacterial soap: These may leave residue, taste, or chemical film on the aligners.
What Stains Invisalign Aligners
Invisalign aligners are made of clear thermoplastic. While they resist staining better than some older clear aligner materials, they are still vulnerable to discoloration from certain foods, drinks, and habits.
Beverages to Remove Aligners For
Coffee, tea, red wine, and colored sodas are the most common causes of aligner staining. Even light-colored beverages like green tea can leave a yellowish tint over time. The rule is simple: remove your aligners before drinking anything other than plain, cool water. Warm or hot water can also warp the aligners, so remove them before drinking hot beverages regardless of color.
Eating and Smoking
Always remove aligners before eating. Food particles trapped between the aligners and your teeth create a breeding ground for bacteria and can stain both the aligners and your teeth. Smoking or vaping with aligners in place causes rapid yellowing that is difficult or impossible to remove. If you smoke, remove your aligners first, although your orthodontist will recommend quitting for overall oral health reasons.
How to Prevent Warping Your Aligners
Warped aligners do not fit correctly and can interfere with your orthodontic treatment. The plastic used in Invisalign aligners softens at relatively low temperatures, so heat is the primary enemy.
Never leave your aligners in a hot car, near a stove, or in direct sunlight for extended periods. Do not use hot water to clean or soak them. When you are not wearing your aligners, store them in their case at room temperature. Wrapping aligners in a napkin is a common way people accidentally throw them away or expose them to heat damage.
Storing Aligners Properly
Always use the Invisalign case provided by your orthodontist. When you remove aligners to eat, rinse them and place them in the case. Never wrap them in a paper towel or set them on a tray at a restaurant. Thousands of aligners end up in the trash each year because they were wrapped in napkins and accidentally discarded. Keep the case with you at all times.
Cleaning Invisalign While Traveling
Maintaining your cleaning routine away from home does not require much extra planning. A small travel kit makes it easy.
Pack a dedicated soft toothbrush for your aligners (separate from your regular toothbrush), a small bottle of clear liquid soap, your aligner case, and a few retainer cleaning tablets. If you cannot brush after a meal while traveling, at minimum rinse the aligners under running water before putting them back in. Bottled water works if a sink is not available. Avoid leaving dirty aligners in a closed case for hours, as bacteria multiply quickly in a warm, moist environment.
When to Contact Your Orthodontist
Contact your [orthodontist](/specialties/orthodontics) if your aligners become visibly warped or no longer fit snugly, if you notice a persistent odor that does not improve with cleaning, if the aligners crack or break, or if you develop sore spots or irritation on your gums. Your orthodontist can determine whether you need a replacement tray or an adjustment to your treatment plan. Most Invisalign providers include a limited number of replacement trays in the treatment cost.
