  • What is Linämel?

    Linämel is a trifecta of cavity fighting ingredients in our LINHART toothpaste. They are:

    THEOBROMINE is an extract of the cocoa bean and helps strengthen enamel.

    FLUORIDE is a hallmark of modern cavity prevention; a naturally occurring ingredient found in rivers and hot springs around the world. The use of Fluoride in toothpaste is a tried and true method for remineralizing and protecting enamel from acid attacks that cause decay.

    XYLITOL is a natural sugar that prevents tooth decay by keeping the mouth at a neutral pH level.

  • Does LINHART Linämel Toothpaste contain Silica?

    Yes, it does contain Silica, which is a mild abrasive that helps clean tooth enamel. However as dentists, we intentionally minimized the amount of silica to ensure that there are no harmful effects such as recession.

    Some "whitening" toothpastes with high levels of silica can abrade your enamel over time, leading to thin enamel, sensitive teeth, gum recession, and other irreversible conditions!

  • Where is LINHART Toothpaste made?

    We proudly make all of our consumable products in the United States, so we can guarantee the quality of ingredients and ensure manufacturing is up to our high standards.

    As dentists in New York City, we wanted to make sure everything is local and under our strict supervision, just like in our dental practice.

  • Does LINHART Toothpaste Whiten Teeth?

    Yes! You should see whiter teeth with daily use; however, for a more significant whitening effect, we recommend that you use our LINHART Tooth Whitener in conjunction with the toothpaste.

  • How much Toothpaste should I use?

    We recommend that you brush your teeth twice a day, every day. Once in the morning and once before bedtime.

    You should use a pea sized amount of toothpaste when brushing, and half that amount for children under 12.

    Children under 3 should not use toothpaste without strict adult supervision!

  • What are the ingredients in LINAMEL Toothpaste?

  • 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!
