Aligner cases, removal tools, and chewies

A case is the one accessory every aligner wearer needs, so the trays have somewhere safe to go when they are out of your mouth. Your usual toothbrush and floss do the rest of the daily work. A removal tool and chewies, soft pieces you bite on to help a tray fit fully (also sold as seaters), are optional, and chewies are worth using mainly if your clinician or aligner system recommends them. None of these accessories has been shown to make treatment faster; progress depends heavily on wearing the trays for the hours prescribed.

The kit at a glance

Prices are from the Invisalign accessory store on October 22, 2026; some items were on sale. Similar generic items are sold widely, often for less.

Choosing a case

• Hard shell. A soft pouch does not stop a tray being crushed in a bag.
• Room for both trays, upper and lower together.
• A clasp that stays shut when dropped.
• A color you will spot on a restaurant table or in a bag. The American Association of Orthodontists (AAO) warns against wrapping aligners in a napkin or putting them in a pocket or purse.
• Easy to clean. The AAO suggests rinsing with cool water, brushing gently with a soft brush and mild soap, and letting it air-dry. Avoid hot water, bleach and the dishwasher.

Invisalign tells its own patients to keep aligners in a case whenever they are out of the mouth. Keep the case away from heat too: a hot car can warp trays just as hot water can.

Toothbrush and floss

Brush and floss before the trays go back in, so food and drink are not trapped against your teeth. The ADA says manual and powered toothbrushes can both clean thoroughly, so use whichever you will use properly: soft bristles, two minutes, twice a day, with fluoride toothpaste. Replace the brush every three to four months, or sooner if the bristles fray. Toothpaste choice is covered in toothpaste with clear aligners.

Removal tools

A removal tool hooks the back edge of a tray and lifts it forward, which can help when a new tray is tight or attachments make it hard to grip. Invisalign sells the PULTOOL for this. Clean it as you would the case. If a tray is cutting you, or you cannot get it off, contact the clinician who prescribed it rather than forcing it.

Chewies

Some systems provide or recommend chewies, which Invisalign sells as seaters. Invisalign says its seaters help close small air gaps between tray and teeth. Follow your own instructions on when and how long to use them. A product page may call one "more powerful"; that is the seller's description, not evidence that treatment speeds up. Chewies are soft and wear out; replace one that is torn.

If a tray still does not fit fully after using chewies as directed, contact the clinician before moving to the next one. Extra aligners are explained in refinement aligners.

A travel and work setup

• Case, with the trays in it whenever they are out
• Travel toothbrush and small toothpaste; let the brush air-dry when you can
• Floss picks
• A bottle of plain water, for rinsing when you cannot brush
• Your previous tray, if your clinician wants you to keep one as a backup
• Optional: cleaning foam for days away from a sink

Eating out and travel are covered in eating and drinking with clear aligners.

Cleaning and whitening products

Cleaning tablets, powders, foam and ultrasonic machines are compared in aligner and retainer cleaners, and the daily routine is in how to clean clear aligners. Whitening is a separate treatment. A pen included with an aligner order is the company's extra; a bleaching plan comes from a dentist who has seen your teeth.
