If you’ve ever shopped for dental floss (and you really should!), you may have noticed there are two common varieties of traditional nylon floss: waxed and unwaxed. While they both serve the same purpose, they feel very different and can work better for different mouths.
If you’ve ever wondered which type is best, here’s a simple breakdown of the pros and cons of each.
Waxed Dental Floss
Waxed floss is coated with a thin layer of wax, which helps it glide more smoothly between teeth. Because of this coating, it tends to be stronger and less likely to tear or shred while you floss.
Many people prefer waxed floss because it feels sturdier and is easier to maneuver, especially if you’re still getting used to flossing regularly.
Benefits of Waxed Floss
- Slides more easily between teeth
- Less likely to shred or break
- Often easier to handle for beginners
Unwaxed Dental Floss
Unwaxed floss does not have the same smooth coating, which means it may feel thinner. Some people actually prefer this because it can fit into very tight spaces more easily. If your teeth are crowded or closely spaced, unwaxed floss may be more comfortable.
However, unwaxed floss can be more likely to fray or snap, especially if your teeth have rough edges or if you have dental work such as fillings or crowns.
Benefits of Unwaxed Floss
- May fit better between very tight teeth
- Often feels thinner and more flexible
- Typically less slippery, which some people prefer
What About Flavor?
Another difference between waxed and unwaxed floss is that waxed floss is more likely to come in flavored varieties, such as mint. For some people, this is a bonus and can make flossing feel fresher and more enjoyable.
On the other hand, if you prefer floss that is plain and unflavored, unwaxed floss may be a better option.
Are There Any Safety Concerns?
Some floss products may contain specialty coatings or materials that help them slide between the teeth more easily. Certain consumers prefer to avoid these coatings due to concerns about specific chemical ingredients used in some floss products.
If you are unsure about the ingredients in your floss, check the packaging or look for brands that clearly label their materials. There are also floss options marketed as natural or chemical-free for those who want a simpler product.
Which Floss Works Better?
The good news is that both waxed and unwaxed floss can effectively clean between your teeth when used properly. The best floss is the one you will use consistently.
If waxed floss slides easier and feels more comfortable, choose waxed. If unwaxed floss fits better between tight teeth, choose unwaxed. The goal is simply to remove plaque and food particles that your toothbrush can’t reach.
What If You Have Braces?
If you have braces, waxed floss is usually the better choice. Unwaxed floss can be more likely to shred and leave small strands behind, which may get caught in brackets and wires.
Many people with braces also find it helpful to use floss threaders, orthodontic floss, or even a water flosser to make cleaning between teeth easier.
The Bottom Line
Waxed and unwaxed floss both get the job done. The right choice depends on your teeth, your comfort level, and your personal preference. If you’re unsure which option is best for your mouth, ask your dentist or hygienist during your next visit—they can recommend the right floss for your needs.
No matter which type you choose, flossing daily is one of the best habits you can build for a healthier smile.
