How we picked the best teeth whitening gel
We reviewed all seven whitening-related listings in the store. Each was scored on concentration, total gel volume, what is in the box and how clearly the listing explains use. Two LumiBrite 4-syringe listings exist; we picked one and show both in the table.

Concentration
LumiBrite is listed at 32% carbamide peroxide and LumiSmile White at 16%. A higher number is not automatically better for everyone; your dentist can tell you which strength suits your teeth and any restorations.
Total gel volume
Most syringes here hold 2.5 mL. Multiply by the syringe count to compare boxes: 5 mL for a 2-pack, 10 mL for a 4-pack and 15 mL for a 6-pack.
Trays
LumiBrite and LumiSmile listings do not include trays. Two LumiBrite listings say the gel is compatible with custom trays, which are usually made by a dental office. Perio Restore is the exception, with two trays in the box.
Flavor and comfort
LumiBrite is mint; LumiSmile White uses peppermint oil. Both listings mention low sensitivity, but individual comfort varies.
Is 32% or 16% carbamide peroxide better?
On paper, 32% carries twice the carbamide peroxide of 16%. The LumiBrite 6-pack listing (B010E1PEQO) pairs the higher concentration with short sessions of 10 to 15 minutes twice a day. LumiSmile's listing leads with minimal sensitivity and results in about 2 weeks.
If you have whitened before without issues, LumiBrite may suit you; if you are new or sensitive, LumiSmile is the gentler starting point. Our LumiBrite 32% review goes deeper on the stronger gel.
Which whitening gel should you buy?
Pick the LumiBrite 4-syringe refill for a standard course, the 6-syringe refill if you want more gel on hand, and the 2-syringe kit for a first try or a touch-up. Choose LumiSmile White if you prefer 16%. For a tray gel that comes with trays and fits a daily routine, Perio Restore is the one to look at.
Whitening works best on clean teeth, so pair it with a good brush and interdental cleaning. See our at-home oral care products roundup and the Rotadent replacement heads guide.
