How Smart Toothbrushes Improve Plaque Removal & Gum Health

Summary

Modern toothbrushes are more than just bristles and a handle. Smart toothbrushes, including the Oral-B iO, use features like pressure sensors, timers, app-connected coaching, and 3D Teeth Tracking to help guide brushing technique, coverage, and pressure. This connected toothbrush experience can help personalize daily brushing through real-time feedback and a toothbrush app. These features can support plaque removal and gum health when used as directed.

The Evolution of Toothbrushing

From early cleaning tools to modern toothbrushes, oral care has continued to evolve. Today, smart toothbrush and AI toothbrush technology can help guide brushing time, pressure, and coverage, while the goal remains the same: remove plaque and support gum health.

As toothbrushes become more connected and personalized, they can help people build better daily brushing habits.

The Problem: Are You Really Brushing Effectively?

Even with years of dental advice, many people still struggle to brush effectively. In a systematic review, manual toothbrushes left an average of 58% of plaque behind after brushing.2 Common brushing challenges include:

• Inconsistent coverage: Missing areas, especially back molars or the tongue side of front teeth.
• Insufficient brushing time: Brushing for less than the dentist-recommended two minutes.
• Too much pressure: Brushing too hard, which can be tough on gums.

Manual Toothbrushing: Relying on Technique Alone

Manual toothbrushes depend heavily on user technique, including brushing angle, coverage, pressure, and brushing time. Without real-time feedback, it can be difficult to clean consistently.

In a meta-analysis of clinical studies, only 21% of manual toothbrush users with early gum disease transitioned to healthy gums by 12 weeks, compared with 88% of Oral-B iO users.

Electric Toothbrushes: A Technology Advantage

Electric toothbrushes can help improve plaque removal and support gum health. A Cochrane review of 56 studies found that electric toothbrushes reduced plaque and gingivitis more effectively than manual toothbrushes in the short and long term.

More recent clinical evidence found that oscillating-rotating electric toothbrushes ranked highest among the toothbrush technologies studied for reducing plaque and gingivitis, ahead of sonic and manual toothbrushes.

Many electric toothbrushes also include features such as pressure sensors, two-minute timers, and quadrant pacing timers to help support better brushing habits.

Oral-B iO: Smart Technology for Plaque Removal and Gum Health

The Oral-B iO combines oscillating-rotating technology with gentle microvibrations to help deliver a thorough brushing experience

Clinical evidence supports oscillating-rotating technology for helping reduce plaque and gingivitis, and recent evidence suggests it ranks highly among compared electric toothbrush technologies.

Key features available on advanced Oral-B iO models include:

• Round brush head for a tooth-by-tooth clean: Oral-B’s dentist-inspired round brush head is designed to surround each tooth, while oscillating-rotating motion and gentle microvibrations help deliver a thorough clean.
• Smart Pressure Sensor: Shows you when you’re brushing too hard, not hard enough, or just right, helping guide you toward the right pressure for effective plaque removal.
• Clinically studied gum-health results: A meta-analysis published in the International Dental Journal found that 88% of Oral-B iO users with early gum disease transitioned to healthy gums by 12 weeks, compared with 21% of manual toothbrush users and 54% of sonic toothbrush users.

Your Personalized Guide: AI Toothbrush Technology and 3D Teeth Tracking

AI toothbrush technology can help make daily brushing feel more personalized by using connected features, real-time feedback, and app-guided coaching to help users understand where, how long, and how effectively they are brushing.

With Oral-B iO, features like 3D Teeth Tracking, the Smart Pressure Sensor, brushing modes, in-app health goals, and a 30-day brushing challenge can help personalize the brushing experience and support better daily habits.

In a global in-market evaluation of more than 16 million brushing sessions, users brushed longer and with less overpressure when using live app feedback, and brushing sessions with position detection achieved 94.4% average coverage.

• Real-time 3D Teeth Tracking: The app uses advanced 3D Teeth Tracking to map brushing coverage across up to 16 zones, helping users see which areas may need more attention.
• Personalized brushing modes: Oral-B iO offers brushing modes such as Daily Clean, Sensitive, Gum Care, Intense, Whitening, Super Sensitive, and Tongue Clean, depending on the model, so users can choose the mode that best fits their brushing needs.
• Smart Pressure Sensor feedback: The Smart Pressure Sensor shows when users are brushing too hard, not hard enough, or just right, helping guide them toward the right pressure.
• App-guided goals and challenges: The Oral-B app can support personalized brushing through features such as health goals, progress tracking, and a 30-day brushing challenge designed to help users build better brushing habits.
• Real-world behavior-change data: In a global real-world evaluation, live app feedback helped users brush longer, use less excessive pressure, and achieve 94.4% average brushing coverage.

The Crest + Oral-B System

Technology isn’t limited to the brush. A complete oral care routine can combine an Oral-B iO electric toothbrush with Crest stannous fluoride toothpaste, Crest CPC oral rinse, and Oral-B Glide floss to support plaque removal and gum health.

• 100% of participants reached healthy gums in a 12-week Crest + Oral-B System study: In a study published in the Compendium of Continuing Education in Dentistry, participants with early gum disease used the full Crest + Oral-B System, including an Oral-B iO electric toothbrush, Crest stannous fluoride toothpaste, Crest CPC oral rinse, and Oral-B Glide floss, and transitioned to a healthy gum state.

Long-Term Benefits: Protecting Your Gums

Healthy gums are an important part of a healthy smile. Oral-B iO is designed to deliver a powerful yet gentle clean.

In a 36-month clinical study of people with existing gum recession, Oral-B iO helped stabilize gum recession over time compared with a manual toothbrush.

Oral Care Habits That Support Gum Health

Smart brushing is one part of a complete oral care routine. Oral-B iO electric toothbrushes can help guide brushing time, pressure, and coverage, while Crest stannous fluoride toothpaste, Crest mouthwash, and daily flossing can help support plaque removal and gum health.

• Brush with Oral-B iO electric toothbrushes to help guide brushing pressure and coverage for a more consistent daily clean. In a long-term clinical study, Oral-B iO helped stabilize existing gum recession over time compared with a manual toothbrush.
• Choose the right brush head, such as the Oral-B iO Gentle Care brush head, which is designed with soft bristles to provide a gentle cleaning experience along teeth and gums.
• Crest Toothpaste with stannous fluoride helps fight plaque bacteria that can contribute to gingivitis. Pairing it with an Oral-B iO electric toothbrush can help support plaque removal and gum health as part of a daily routine.
• Add mouthwash, such as Crest Mouthwash, to help support plaque control as part of a complete oral care routine.
• Floss daily with a floss that can fit more easily into tight spaces, such as Glide Floss, to help support gum health as part of a complete routine.

Oral health is part of overall health. Taking steps to help reduce plaque, gingivitis, and tooth decay can support a healthier daily routine.
