What are the ingredients of the whitening syringe gel?
Ingredients: Glycerin, Urea Peroxide, Propylene Glycol, Xylitol, Carbomer, Mentha Piperita (Peppermint) Oil, Triethanolamine, Aqua
Xylitol: 100% natural sweetener derived from vegetable sources has low impact on blood sugar, reduces tooth decay and treats dry mouth. We use xylitol in multiple LINHART products like our toothpaste and tooth whitener gel.
Urea / Hydrogen Peroxide: extremely gentle with oxidizing properties that act like a bleaching agent when used in our whitening gel.
Carbomer: another teeth whitening agent that works with an oxidizing effect, unlocking your teeth’s whitest shade!
Mentha Piperita (Peppermint) Oil: adds a clean, refreshing taste plus has the medicinal and germicidal benefits of diminishing harmful bacterial growth inside the mouth, leaving breath smelling and feeling fresh.

What is the difference between your Linhart Whitener Gel tube and Whitening Syringes?
Good question! Both of these gels have been specifically formulated to achieve teeth whitening, however even though they seem similar, they are used in very different ways.
Our Whitening Syringes are meant to be used inside either our 16-LED Whitening Light tray, or custom trays made by your dentist (or us at Linhart Dentistry)! The gel is meant to be left on your teeth for 30-60 minutes a few times a week for a significant whitening boost.
Our Tooth Whitener Gel is placed on top of your regular toothpaste, preferable Linhart Toothpaste, and then you brush as usual. The gel is a great way to enhance your smile and maintain optimal white teeth long term.
Both of these gels are included in The Whitening Collection!
