Daily oral care goes beyond brushing your teeth. A significant amount of plaque and food debris accumulates between teeth, where toothbrushes struggle to reach. That’s why dentists recommend using tools like dental floss, interdental brushes, or a water flosser. But which method is truly the most effective? In this blog, we compare the three based on scientific data, ease of use, and overall effectiveness—and explore how HAIDU products can support optimal oral hygiene.

What does flossing actually do?

Traditional flossing with dental string helps remove plaque and food particles between the teeth and below the gumline. It's affordable, widely available, and effective—if used correctly.

However, studies show that many people don’t floss properly. According to the American Dental Association (ADA), only 30% of users floss effectively. Incorrect technique can also cause gum damage.

How effective are interdental brushes?

Interdental brushes are small, bristled tools that fit between teeth. They are especially useful for people with larger gaps or receding gums. A study published in the Journal of Clinical Periodontology found that interdental brushes are more effective than floss in reducing gingivitis and plaque when used daily.

Advantages of interdental brushes:

• Greater surface area coverage
• Easier to handle than floss
• Less risk of improper use

Downside: not suitable for people with very tight spaces between teeth.

What is a water flosser and does it really work?

A water flosser (also known as an oral irrigator) uses a pulsating stream of water to clean between the teeth and beneath the gumline. This makes it ideal for people with braces, implants, or sensitive areas.

A clinical study in the Journal of Clinical Dentistry showed that using a water flosser alongside brushing is 29% more effective at removing plaque than brushing alone. It also reduced gum bleeding by 93% within four weeks.

Benefits:

• Very user-friendly
• Gentle on sensitive gums
• Reaches hard-to-access areas

Limitation: less effective at tightly packed contact points between teeth.

What do dentists say?

Dentist and periodontist Dr. Jeroen Hoekstra notes: “For patients with healthy gums and tight spaces, flossing is a good option—if done correctly. But for those with inflamed gums or periodontal issues, I recommend interdental brushes or a water flosser.”

The Dutch Dental Association (NMT) also acknowledges that no single tool fits all. Personal preference, dexterity, and dental structure all play a role.

What suits you best?

• Dental floss: Great for people with tight tooth gaps and healthy gums.
• Interdental brushes: Recommended for larger spaces, braces, or receding gums.
• Water flosser: Ideal for sensitive gums, orthodontics, implants, or limited dexterity.
• Electric flosser: Excellent for cleaning tight interdental spaces where water flossers fall short.
