Wondering if CariFree toothpaste pairs well with your electric flosser? We explain how its nano-hydroxyapatite and fluoride formula complements flossing for better cavity protection.
Quick Answer
Yes, CariFree toothpaste works perfectly with any electric flosser, including the Slate Pro. The toothpaste's remineralizing ingredients and low abrasion formula are designed to complement mechanical cleaning, not interfere with it. Use the flosser first to dislodge debris, then brush with CariFree for maximum fluoride and nano-hydroxyapatite uptake.
How CariFree Toothpaste Complements Electric Flossing
Electric flossers like the Slate Pro remove plaque and food from between teeth and along the gumline. Once those surfaces are clean, brushing with CariFree toothpaste allows its active ingredients—0.24% fluoride and nano-hydroxyapatite—to reach enamel more effectively. The patented pH+ technology in CariFree also neutralizes acids left behind by bacteria, creating a friendlier environment for remineralization.
Because CariFree is a low-abrasion gel, it won't wear down enamel even when used twice daily. This makes it a solid choice for anyone using an electric flosser regularly, since the combination of mechanical cleaning and chemical remineralization tackles both plaque and early decay.
Can You Use CariFree Toothpaste with the Slate Pro Electric Flosser?

Absolutely. The Slate Pro uses woven floss, gum brushes, and sonic vibrations to clean areas a toothbrush can't reach. CariFree toothpaste is applied with a toothbrush, not the flosser, so there's no conflict. In fact, the Slate Pro's tongue scraper can help remove bacteria before you brush, letting the toothpaste's nano-hydroxyapatite and fluoride work on a cleaner surface.
One practical tip: after flossing with the Slate Pro, wait a few seconds before brushing to allow saliva to rebalance. Then brush with a pea-sized amount of CariFree for two minutes. Avoid rinsing immediately afterward so the active ingredients stay on your teeth longer.
What Makes CariFree Toothpaste Different from Standard Toothpaste?
CariFree Gel 1100 combines two cavity-fighting agents: 0.24% fluoride (a proven anti-cavity ingredient) and nano-hydroxyapatite (nanoXIM by FLUIDINOVA), which is globally recognized for oral care. The nano-hydroxyapatite particles can fill microscopic pores in enamel, helping to remineralize early white spots. The pH+ technology further neutralizes dietary and bacterial acids.
Standard toothpastes often rely on fluoride alone or use higher abrasivity to remove stains. CariFree's low-abrasion formula is gentler on enamel, making it a better match for people who floss daily and want to preserve tooth structure over the long term.
Frequently Asked Questions
- Should I floss before or after brushing with CariFree?
- Floss first. The Slate Pro or any electric flosser removes debris and plaque, allowing the fluoride and nano-hydroxyapatite in CariFree to reach enamel directly. Brush afterward and don't rinse for at least 30 minutes. Floss → brush → wait → better remineralization.
- Can I use CariFree toothpaste with a water flosser instead of an electric flosser?
- Yes, CariFree works with any flossing method. However, an electric flosser like the Slate Pro uses woven floss that physically scrapes plaque, which may expose more enamel surface for the toothpaste to treat. Water flossers are gentler but less effective at removing sticky biofilm. Electric flossers may enhance CariFree's remineralization benefits.
- Is CariFree safe for sensitive teeth and gums?
- Yes. Its low-abrasion formula and pH-neutralizing technology make it suitable for sensitive mouths. The nano-hydroxyapatite can also help reduce sensitivity by sealing exposed dentin tubules over time. A good option if you experience sensitivity from flossing or brushing.
Product Facts
- CariFree Toothpaste (with Fluoride and Nano-Hydroxyaptite): CariFree Gel 1100 combines 0.24% fluoride, nano-hydroxyapatite (nanoXIM by FLUIDINOVA), and patented pH+ technology to neutralize acids and remineralize teeth. It is a low-abrasion floss serum. The low abrasion means it won't wear down enamel when used with an electric flosser routine, and the nano-hydroxyapatite can repair early decay that flossing exposes.
