Toothpaste while you wear clear aligners

For most people, the best toothpaste while you wear clear aligners is an ordinary fluoride toothpaste you are happy to use several times a day; you do not need one marketed for aligners. If you want extra help with sensitivity, gum health or surface stain, choose a fluoride paste that carries the American Dental Association's Seal for that job. If your dentist has recommended a particular paste for your teeth, use that. Cleaning the trays is a separate step, usually with water and a soft brush, and depends on your aligner's instructions.

Why toothpaste matters more with aligners

Aligners sit over the teeth for most of the day. They can trap liquids and food against the teeth, raising the risk of cavities and gum disease, so the American Association of Orthodontists asks wearers to brush before putting the trays back in after eating or drinking anything but water. Depending on how often you eat, that can mean brushing more than twice a day. The toothpaste does the same job as before; you use it more often, so pick one you are comfortable with.

The ADA recommends brushing twice a day with a fluoride toothpaste. Over-the-counter fluoride toothpastes in the US generally contain 1,000 to 1,500 parts per million (ppm) of fluoride, as sodium fluoride, sodium monofluorophosphate or stannous fluoride; the Drug Facts panel names the one in your tube.

Choosing by the job it does

The ADA Seal of Acceptance is a voluntary program: a company submits evidence, and the ADA lists the specific claims it accepts for that product, such as helping prevent cavities or reducing sensitivity. These are examples from the Seal list, checked on October 22, 2026. They are not a ranking, and other accepted products exist.

What whitening toothpaste can and cannot do

The ADA says all toothpastes remove some surface stain through mild abrasives, and that whitening toothpastes accepted for stain removal have extra polishing agents. Unlike bleaching products, they do not change the natural color of the teeth; they only remove stain on the surface. One quirk: US labels for stannous fluoride toothpastes note that the ingredient can itself cause surface staining, which good brushing usually prevents and a dentist can remove. Bleaching during aligner treatment is a separate question for your dentist, covered in teeth whitening and clear aligners.

Sensitive teeth during treatment

Teeth can feel tender for the first days of each new tray. If they are sensitive to hot, cold or sweet things, tell the dentist or orthodontist looking after your treatment.

A sensitivity toothpaste with the ADA Seal is an ordinary option. It is not an aligner treatment, and it does not replace a check if one tooth keeps hurting.

After food and acidic drinks

Brush before the trays go back in whenever you can. If you cannot brush straight away, rinse your mouth and the trays with water, put them back, and brush at the next chance. After acidic food or drink, the ADA's news service suggests waiting about 30 minutes before brushing, and notes that brushing before breakfast avoids the issue at that meal. Ask your orthodontist how to fit that wait around your wear time. Habits that help are in eating and drinking with clear aligners.

Cleaning the trays is a different step

Toothpaste is for teeth. For the trays, follow the instructions for your appliance. Invisalign's usual care note is a soft brush and lukewarm water; one Invisalign page allows a small amount of toothpaste on the aligner, and its Vivera retainer page asks for a non-abrasive toothpaste. Where the instructions ask for a non-abrasive paste, that rules out gritty whitening pastes. Do not leave toothpaste in the trays in place of brushing your teeth. Tablets, powders and foams made for aligners are compared on the aligner and retainer cleaner page.
