Smileactives Whitening Power Kit vs SmilePro Ultimate Whitening Set

The SmilePro Ultimate Whitening Set is the better buy for most people. It pairs a red and blue LED light with 6% hydrogen peroxide gel and potassium nitrate, includes 60 treatments plus toothpaste, and holds a 4.8 rating from 8,489 buyers. The Whitening Power Kit is a simpler gel-and-pen routine with no light, a 3.8 rating from 8,715 buyers, and a gentler no-sensitivity claim. Both promise up to 8 shades in about two weeks; SmilePro gets there in a 7-day course, the Power Kit in 14 days.

  • Choose the Whitening Power Kit if you want a low-effort routine you add to your existing toothpaste and prefer a pen for spot stain touch-ups without an LED light.
  • Choose the SmilePro Ultimate Whitening Set if you want a full LED course, a fixed 10-minute routine, and enough pens and toothpaste to maintain results for over a year.

Questions and answers

Which is better for fast results?
SmilePro. Its 7-day LED course claims up to 8 shades, while the Power Kit spreads the same claim over 14 days.
Which is gentler on sensitive teeth?
Both are built for comfort. The Power Kit leans on its Polyclean foam and no-sensitivity claim; SmilePro adds potassium nitrate to its peroxide gel and buyers report no sensitivity.
Is the SmilePro set worth stepping up to?
Yes if you want an LED light, a fixed 10-minute routine and a year of top-ups in one box. The Power Kit suits people who want whitening folded into brushing.
Will either work on stains from antibiotics or thin enamel?
SmilePro buyers report it does not. Neither kit is a fix for intrinsic staining; see a dentist for those cases.
Can I use the Power Kit with veneers or crowns?
The maker says it is safe for veneers, crowns and dentures. SmilePro's peroxide gel is the more conventional choice for natural teeth.
How long does each set last?
SmilePro covers a 7-day course plus bi-weekly top-ups for over a year. The Power Kit's 60 gel treatments last about two months of daily use, with the pen for upkeep.
