LA Pacific Enzyme Whitening Stain Removal Toothpaste might just be the world's very first enzymatic whitening toothpaste. Offering at-home results, the enamel-safe toothpaste promotes a whiter and brighter-looking smile without the harmful effects of using hydrogen peroxide. Through consistent use, it helps polish the look of teeth, brightening and fortifying against future staining. There's no synthetic bleach, giving you teeth whitening that doesn't damage teeth in any way or cause sensitivity. There isn’t enough clinical evidence to support cannabidiol, aloe vera, or vitamin E for gum health, and as with Colgate's gum toothpaste, ‘invigorate gums’ is not a scientifically meaningful phrase. Created by oral care experts, the formula combines LA Pacific’s unique whitening enzyme along with:

Zendium gave us evidence from clinical studies that support the combination of antibacterial enzymes in this toothpaste (amyloglucosidase, lysozyme, glucose oxidase, lactoperoxidase and lactoferrin) for plaque control and to reduce gum inflammation and bleeding. Colgate told us its studies on Elixir White are confidential so it was unable to provide us with any specific evidence to show it's better than other whitening toothpastes.

Hydrogen peroxide (a bleaching agent) is commonly used in whitening toothpastes, but it's a bit of a red herring as the legal limit for over-the-counter toothpastes is too low to actually affect the colour of your teeth. But, you can find the same or similarly effective stain-removal ingredients in cheaper products too.

Glucose oxidase and zinc are antibacterial agents that help with mild to moderate gum disease, stannous fluoride and stannous chloride can reduce toxins that cause inflammation.But there are also plenty of marketing claims, such as ‘strengthens enamel’ and ‘prevents decay’, that are redundant because all fluoride toothpastes, regardless of price, will do these things. Colgate said evidence for this formulation was also commercially sensitive, but there is evidence that the zinc oxide and zinc citrate combination used has antibacterial properties, which our experts said should give this product advantages in reducing gum inflammation vs basic fluoride toothpastes. Eugenol and ginseng root extract may have antibacterial properties that help reduce gum swelling or bleeding, but we didn’t see robust evidence about their concentration or action in this specific toothpaste. Stain removal should be reasonable with this toothpaste (better than regular fluoride toothpaste), thanks to abrasives such as silica, and surfactants (foaming agents) including sodium lauryl sulfate and cocamidopropyl betaine, plus the addition of phosphates for tartar reduction.

Toothpaste alone isn't a magic solution though. Proper brushing technique and interdental cleaning are also vitally important for good gum health. SensitivityZendium's marketing based on oral bacteria and enzymes instead of minerals is unique, but again, while it will be better than conventional toothpastes at reducing gingivitis, cavity protection should be similar. Low abrasion Silica works to gently remove stains from the surface of the tooth and restores the natural brightness. RDA Relative dentin abrasivity 75​​* Hydrated silica and calcium carbonate are mild abrasives that work to remove surface stains on teeth, while pyrophosphates can reduce calculus and tartar formation. Through consistent use, it helps polish the look of teeth, brightening and fortifying against future staining. Pentasodium Triphosphate - acts as a stain dissolving agent preventing food particles from settling on the teeth.
