Dentists recommend replacing the floss head once a week to ensure optimal oral hygiene. Users with tighter teeth may need to replace it every 3-5 days. If you need replacements, feel free to subscribe on our website for the best prices.
Each box contains 12 replacement floss heads. If you replace them weekly, one box can last up to 3 months. If your teeth are tighter or you use them more frequently, we recommend ordering every 2 months to ensure you always have enough. You can subscribe on our official website for better prices, and the refills will be automatically delivered to your doorstep, so you never run out or forget to order.
SLATE floss does not contain any harmful chemicals such as PTFE (polytetrafluoroethylene) or PFAS (per- and polyfluoroalkyl substances). We use an uncoated woven floss made from ultra-high molecular weight polyethylene (UHMWPE), which is Teflon-free.
SLATE’s nano-hydroxyapatite (nHA) is a natural mineral that effectively helps remineralize tooth enamel. We use it as a natural alternative to fluoride to combat tooth demineralization, making your teeth healthier.
The classic gray and new white floss heads have no flavor or coating and contain no chemicals. The light blue nano-hydroxyapatite floss head contains natural nano-hydroxyapatite, which helps restore tooth enamel. All floss heads are made from ultra-high molecular weight polyethylene and are Teflon-free.
In principle, the material of our floss heads is very durable, and using cleaning agents will not damage the material or affect its function. However, since this is a product that comes into direct contact with the mouth, to avoid any residue from cleaning agents entering your mouth, we recommend cleaning it the same way you would clean a toothbrush: rinse with water and let it air dry. Alternatively, you can use a small amount of toothpaste for enhanced cleaning. This way, it stays clean and safe! 🦷✨
Yes! The SLATE Multi-Functional Electric Flosser can gently and effectively clean around dental crowns without causing any damage.
Yes! Our electric flosser has an IPX7 waterproof rating, ensuring it can be used underwater at a depth of 1 meter for up to 30 minutes without damage. You can safely use it in the shower.
Currently, our electric flosser cannot be used with a lingual retainer. However, you can still use it to clean the posterior teeth, as most cavities occur in that area.
We apologize, but currently, the SLATE Multi-Functional Electric Flosser cannot be used with dental bridges. However, we are working hard to develop related products, so stay tuned!
Hello! We completely understand your hesitation because this is a new category in oral care. Traditional floss is great, but our goal is to make "using floss daily" easier and more enjoyable. SLATE is loved by over 25,000 users and recommended by more than 500 dental professionals. We believe that the best tool is the one you are most willing to use every day. We hope you will give it a try! 😊
This is a great question and one of the most common concerns we hear. The "pain" or discomfort you feel may actually be a warning sign that your gums are inflamed. As our collaborating dentist, Dr. Zhao, says, mild discomfort or bleeding in the early stages is a reminder that you "must start" cleaning between your teeth. After a few days of gentle and consistent use, the inflammation will improve, and the discomfort will disappear. This is the only way to make your gums healthier! Stick to daily flossing, stick to daily SLATE.
This is a very common misconception! In fact, the opposite is true. When you don’t use floss, dirt accumulates in the gaps between your teeth, causing the gums to become "inflamed and swollen." When you start using floss and remove this dirt, the gums "de-swell" and return to a tight, healthy state. The "gaps" you see are actually the healthy state of your gums after the swelling has subsided. They have always been there, but were previously covered by swollen gums. Using floss does not make the gaps between teeth larger; it makes your gums healthier!
This is a great question! Our floss heads are reusable and made from 450+ strands of woven fibers, making them very durable. Dentists recommend replacing the floss head "once a week" to ensure optimal cleaning. After each use, simply rinse with water and let it air dry. Currently, individual purchases come with 5 floss heads that can last for 5 weeks. If you purchase a refill box (12 pieces), it can last about 3 months under normal use!
Yes, with traditional floss, dirt easily attaches to the thin thread, so you may need a new section for each gap. The SLATE Electric Flosser uses sonic vibrations to shake off the dirt, so the floss head does not easily get dirty. Just like a toothbrush, you can rinse it with water and continue cleaning the next area. Our floss heads are made from 450+ strands of woven fibers, making them very durable and reusable. Dentists recommend replacing the floss head once a week for optimal cleaning. After each use, simply rinse with water and let it air dry. Currently, we provide 5 floss heads that can last for 5 weeks, and a refill box (12 pieces) can last about 3 months under normal use!
This is the advantage of SLATE’s replaceable head design! If the floss breaks (or after a week of use), you simply remove the old floss head and "click" a new one into place. It’s quick, convenient, and more eco-friendly than disposable floss picks!
Thank you for your suggestion! SLATE’s brush head is compact and angled, making it easy to clean the posterior teeth (where most cavities occur). We will film more cleaning videos for the posterior teeth in the future!
