Costco is known for bulk deals on everything from groceries to electronics, and dental care is no exception. If you've been browsing Costco teeth whitening kits, you've probably noticed a mix of LED devices, whitening strips, and bundle packs from brands like Crest, SNOW, and CurrentBody, each with different price points and claims. Figuring out which one is actually worth your money takes a bit of digging.
At Remi, we make custom dental night guards, retainers, and teeth whitening foam designed alongside in-house dentists, so we spend a lot of time evaluating what works (and what doesn't) in oral care. That perspective helps us break down these kits with a practical eye, not just on price, but on what you're actually getting for it.
Below, we've rounded up five teeth whitening kits currently available at Costco, complete with pricing, what's included in each bundle, and key details to help you compare. Whether you're looking for a simple strip-based routine or a full LED whitening system, this list covers the range so you can pick the right fit without second-guessing your cart.
1. Crest 3D Whitestrips Professional Effects
Crest 3D Whitestrips Professional Effects is one of the most recognized names in at-home teeth whitening, and Costco regularly carries it in a larger bundle than what you'd find at a drugstore, making it one of the more popular costco teeth whitening kits on the shelf.
What you get in the Costco bundle
Costco typically packages this product with 44 strips (22 treatments), which covers a full whitening cycle. The bundle often includes a bonus set of Whitestrips or a whitening toothpaste, giving you more product per dollar than the standard retail box.
How it whitens and how fast it works
The strips use hydrogen peroxide gel that penetrates the enamel surface to break down stain molecules from the inside. Crest states you can see noticeable results after three days of daily use, with the full recommended cycle running 20 days at 30 minutes per treatment.
Consistent daily use drives results here far more than occasional application does.
Who it suits best
This kit works best for people dealing with surface and moderate staining from coffee, tea, or red wine. If you haven't used whitening strips before, the Professional Effects formula is a reliable entry point with a long track record of consumer use.
Typical Costco price range and deal timing
Costco prices this bundle between $45 and $55, depending on your warehouse location. You're more likely to catch a discounted price in early spring or around the holidays when Costco rotates oral care promotions through its seasonal deals.
Sensitivity and safety notes
Some users experience tooth sensitivity or mild gum irritation during or after the treatment cycle. Crest recommends skipping a day if discomfort develops and avoiding these strips if you have crowns or veneers on your front teeth, as the peroxide won't affect existing dental work the same way it does natural enamel.
2. Crest 3D Whitestrips Professional Treatments
Crest 3D Whitestrips Professional Treatments take a different approach than Professional Effects by focusing on faster, more intensive sessions rather than a 20-day daily routine. If your schedule doesn't allow for a longer whitening cycle, this option among Costco teeth whitening kits may fit better.
What you get in the Costco bundle
Costco typically packages this product with two boxes totaling 20 strips (10 treatments), sometimes paired with a whitening toothpaste or a bonus strip pack. The bundled quantity gives you more product per dollar than a single retail box at a drugstore.
How it whitens and how fast it works
These strips use a higher hydrogen peroxide concentration that works in just one hour per treatment. Crest states visible results can appear after a single session, making it a practical pick when you need quick improvement before an event or appointment.
One-hour treatments deliver noticeable whitening faster, but consistent use across the full cycle drives lasting results.
Who it suits best
This kit works best for busy users who want meaningful results without committing to a daily 30-minute routine spread across three weeks.
Typical Costco price range and deal timing
Costco prices this between $40 and $50, with periodic promotional pricing tied to seasonal oral care deals throughout the year.
Sensitivity and safety notes
The higher peroxide concentration makes sensitivity more likely here than with standard strips. Take a break between treatments if you notice gum irritation or tooth discomfort developing during the cycle.
3. Crest 3D Whitestrips with Monthly Brighteners
Crest 3D Whitestrips with Monthly Brighteners adds a maintenance layer on top of a standard whitening cycle. Among Costco teeth whitening kits, this option suits people who want ongoing brightness rather than treating stains after they've already built up.
What you get in the Costco bundle
Costco packages this with a full Professional Effects set plus dedicated monthly brightener strips designed to extend your results between deeper whitening sessions.
How to use the monthly maintenance treatments
Complete the initial whitening cycle with the standard strips first, then apply the monthly brightener strips once per month to stop surface stains from creeping back.
Staying consistent with the monthly treatments is what keeps results from fading within weeks of finishing the main cycle.
Who it suits best
This kit works best for people who drink coffee or tea daily and want a low-effort routine to keep new staining from accumulating over time.
Typical Costco price range and deal timing
Costco typically prices this bundle between $45 and $55, with occasional discounts tied to seasonal oral care promotions throughout the year.
Sensitivity and safety notes
The brightener strips carry a lower peroxide concentration than the main treatment set, which keeps sensitivity risk lower during the ongoing maintenance phase compared to the initial cycle.
4. SNOW Teeth Whitening LED Wired Kit
SNOW takes a different approach from strip-based options, combining a serum applicator with an LED mouthpiece for a hands-free whitening session. Among the available costco teeth whitening kits, this one stands out for its device-driven format.
What you get in the Costco kit
The Costco bundle includes the wired LED mouthpiece, multiple whitening serum wands, and a charging cable, giving you everything needed to start your first session right out of the box.
How the gel and LED system work
You apply the serum directly to your teeth using the wand, then wear the LED mouthpiece for roughly 9 to 30 minutes. The LED light activates the serum to accelerate the whitening process beyond what the formula alone would achieve.
The LED accelerator is what separates this system from strip-only options when speed matters.
Who it suits best
This kit works best for people who prefer a device-based routine and want a faster treatment window than traditional strips offer.
Typical Costco price range and deal timing
Costco typically prices this kit between $60 and $80, with occasional markdowns during seasonal oral care promotions throughout the year.
Sensitivity and safety notes
SNOW formulates its serum to reduce irritation, but users with existing sensitivity should start with shorter sessions to gauge tolerance before committing to the full treatment time.
5. CurrentBody Skin Teeth Whitening Kit
CurrentBody is better known for its LED skincare devices, but the brand also produces a teeth whitening kit that has made its way into Costco teeth whitening kits offerings, bringing a more clinical aesthetic to the at-home whitening category.
What you get in the Costco kit
The Costco bundle includes the LED tray mouthpiece, a set of whitening gel syringes, and a charging cable. Everything ships together so you can start your first session without needing any additional purchases.
How the LED tray system works
You apply the whitening gel to the tray, insert it, and run a session for around 16 minutes. The blue LED light accelerates the gel's whitening action, similar to in-office lamp systems but scaled for home use.
Consistent sessions across the full recommended cycle matter more than any single treatment for lasting results.
Who it suits best
This kit works best for people who want a device-forward routine with a clean, minimal setup and are comfortable with a tray-based format instead of strips.
Typical Costco price range and deal timing
Costco typically prices this kit between $70 and $90, with promotional markdowns appearing during seasonal oral care sales.
Sensitivity and safety notes
Start with shorter sessions if you have sensitive teeth, and follow the gel application instructions closely to avoid unnecessary gum contact.
Quick recap
All five Costco teeth whitening kits covered here get the job done, but they work differently and suit different needs. Crest Whitestrips remain the most accessible option for straightforward strip-based whitening, with the Professional Effects, Professional Treatments, and Monthly Brighteners versions covering different timelines and maintenance goals. If you prefer a device-driven routine, the SNOW LED Wired Kit and CurrentBody LED tray system both accelerate results using blue light activation, though they come at a higher price point than strips.
Your best pick depends on how much time you can commit per session, how often you plan to whiten, and whether you want a one-time cycle or an ongoing routine. None of these kits protect your teeth from grinding or clenching at night, though. If that is something you deal with alongside wanting a brighter smile, a custom night guard from Remi adds protection without the dental office price tag.
