Invisalign uses a series of clear, removable plastic trays to straighten teeth, and each set of aligners fits your teeth closely. You switch to a new set every one to two weeks. Since the trays sit against your teeth most of the day, their condition affects your oral health. Here are some tips and daily habits for cleaning and wearing your aligners:
Take Them Out While Eating
When you eat with aligners in, food particles get trapped between the plastic and your teeth. Chewing also puts pressure on the trays and may crack or bend them. Hot drinks may warp the plastic, and colored drinks like coffee or red wine may stain it. Plain, cool water is an exception.
Remove your aligners before every meal or snack, and place them in their case right away. If you wrap them in a napkin, you risk throwing them away by accident. Keep the Invisalign case in your bag or pocket during the day.
Brush and Floss Before Replacing
Food and plaque stay on your teeth after a meal. If you put your aligners back in right away, the trays hold that debris against your enamel. Bacteria then feed on the trapped sugars, and the risk of cavities and bad breath goes up. Follow these steps before you put your aligners back in:
- Brush all surfaces of your teeth for two minutes.
- Floss between each tooth to remove trapped food.
- Rinse your mouth with water.
- Rinse the aligners under lukewarm water.
- Check the trays for leftover food.
Skipping these steps might save time, but it puts your teeth at greater risk for decay and gum issues. Always clean your teeth and aligners thoroughly to maintain a healthy smile. If you consistently follow this routine, you’ll protect your enamel and prevent bad breath.
Wear 22 Hours Per Day
Aligners apply steady pressure to your teeth, and each tray moves them a small distance. Orthodontists recommend wearing your aligners at least 22 hours per day. When you leave the trays out longer, your teeth have time to shift back toward their old positions. This schedule leaves some time for meals, snacks, and cleaning.
Missed hours add up quickly over a week. Your next set of aligners may not fit well, and your dentist may need to adjust your treatment timeline. If a new tray feels very tight or does not seat fully, contact your dental office. Short wear time may also extend your overall treatment.
Since meals break up the day, many patients set phone reminders to put their trays back in. A simple log of your wear time also helps. Some people track hours in an app, and others use a notebook. Bring this record to your check-ups for a clear view of your progress.
Don’t Use Toothpaste for Aligners
Many people brush their aligners with toothpaste, but most toothpastes contain mild abrasives. When these particles rub against the plastic, they leave tiny scratches on the surface. Scratches collect bacteria and make the trays look cloudy. Try these gentler cleaning options instead:
- Soft toothbrush with clear, unscented liquid soap
- Specific cleaning crystals or tablets made for clear trays
- Short soaks in a dentist-approved cleaning solution
- Lukewarm water only, since hot water warps the plastic
