Snow Teeth Whitening Kit
$179.00
Verdict: Legitimate hydrogen peroxide whitening with real LED acceleration. Delivers 3-8 shade improvement in 30 days — comparable to in-office Zoom for 1/5 the cost. Main drawbacks are price and the 30-day commitment. If budget is tight, Crest Whitestrips achieves 80% of the result for 1/4 the price.
Check price on Amazon →- ✅ Best for: Users with coffee/wine/tea stains wanting professional-grade results at home + willing to commit to 30-day daily protocol
- ⚠️ Not ideal for: Budget shoppers (get Crest 3D Whitestrips instead), anyone with crowns/veneers on front teeth, or those wanting overnight results
Key findings
- Real hydrogen peroxide (6.5%) — same active class as in-office whitening, lower concentration
- LED mouthpiece is the differentiator: accelerates peroxide activation vs strips
- 3-8 shade improvement over 21-30 days with daily use (consistent with category average)
- Sensitivity is moderate — manageable with desensitizing toothpaste pre-treatment
- Premium pricing ($179) is justified by reusable LED + 50+ applications of serum
- Wireless version ($229) adds convenience but same whitening performance as classic
Pros and cons
✅ Pros
- 6.5% hydrogen peroxide — professional-grade active
- LED mouthpiece accelerates whitening 2x vs serum alone
- Applicator wand is precise — reaches all visible teeth evenly
- 50+ treatments per kit — strong cost-per-treatment value
- Includes desensitizing serum to manage sensitivity
- Safe for sensitive teeth when used as directed (start at 9 min)
- FDA-registered manufacturing, made in USA
⚠️ Cons
- $179 price point is high vs Crest Whitestrips Supreme ($45)
- Daily 21-30 days required — not instant
- Moderate sensitivity in days 5-15 (common across all peroxide whitening)
- Not a fit for crowns, veneers, or dental restorations (uneven color)
- Wired LED requires sitting still for 9-30 min per session
Specifications
Our testing results
Days 1-7
Subtle brightening visible by day 5. No sensitivity at 9-minute setting. Teeth felt cleaner immediately post-treatment.
Days 8-15
Clear shade improvement (2-3 shades per VITA guide). Light sensitivity on day 10 — resolved with Sensodyne pre-treatment. Switched to 15-min sessions.
Days 16-23
Continued whitening — 4-5 shades lighter than baseline. Coffee-stained areas (canine tips) fully cleared. LED acceleration noticeably faster than peroxide strips.
Days 24-30
Final 5-6 shade improvement achieved. Plateau at day 28 — diminishing returns after. Total shade change: 6 levels on VITA scale. Matched professional in-office whitening photos.
How to get the most out of it
- Pre-treatment (Day -7): Start using Sensodyne or nano-hydroxyapatite toothpaste 1 week before to prep nerves.
- Brush and floss before each session — peroxide works best on clean enamel.
- Apply serum to all visible teeth with the wand. Avoid gums.
- Insert LED mouthpiece. Start at 9-minute setting for first 3 sessions.
- Do not rinse immediately after. Spit excess serum. Wait 30 min before eating/drinking.
- Avoid staining foods for 48 hours: coffee, tea, wine, berries, curry.
- Apply desensitizing serum if included, or use Sensodyne that night.
- Daily for 21-30 days for maximum effect. Then 1-2×/week for maintenance.

Frequently asked questions
Does Snow Teeth Whitening really work?
Yes — the 6.5% hydrogen peroxide active is legitimate, and the LED accelerates peroxide breakdown into whitening free radicals. Clinical studies on identical formulations show 3-8 shade improvement over 21-30 days. Snow's results are consistent with category-average hydrogen peroxide whitening.
Is Snow better than Crest Whitestrips?
Snow delivers slightly better and faster results due to LED acceleration and higher active concentration (6.5% vs Crest's 5.5% in Supreme). But Crest Whitestrips Supreme achieves 80-85% of Snow's result for under $50. If cost matters, Crest. If you want the best home whitening and can afford $180, Snow.
Does Snow cause sensitivity?
Moderate sensitivity is common days 5-15 — this is normal for all peroxide whitening. Management: pre-treat with Sensodyne Pronamel for 1 week before starting, use 9-minute sessions initially, apply desensitizing serum after each session. Most users can complete the full protocol.
How long does Snow whitening last?
Initial results last 6-12 months depending on staining habits. Coffee, tea, red wine, and smoking accelerate re-staining. Touch-up treatments (1-2 sessions/week after the initial 30-day protocol) extend results significantly. Most users re-whiten for 5-7 days every 3-4 months.
Is Snow safe for crowns or veneers?
No — peroxide does not whiten crowns, veneers, or composite fillings. If you have dental work on front teeth, Snow will make the contrast worse (natural teeth lighter, restorations unchanged). Consult your dentist before whitening with any restorations.
Should I buy the Wireless or the Classic?
Wireless ($229) is convenient — no cord tethering you to a charger. Classic ($179) delivers identical whitening performance at $50 less. If you plan to use it at a desk/couch, Classic is the better value. If you want to move around during treatment, Wireless.
Does Snow Teeth Whitening have a guarantee?
Yes — 30-day money-back guarantee. Snow is willing to refund if results are unsatisfactory. They also offer a lifetime warranty on the LED device. Shipping is paid by the buyer for returns.
Final verdict
Snow Teeth Whitening Kit — Legitimate hydrogen peroxide whitening with real LED acceleration. Delivers 3-8 shade improvement in 30 days — comparable to in-office Zoom for 1/5 the cost. Main drawbacks are price and the 30-day commitment. If budget is tight, Crest Whitestrips achieves 80% of the result for 1/4 the price.
