What You'll Learn

Oral-B electric toothbrushes
Oral-B toothbrushes feature 3D Cleaning Action technology, which provides superior plaque removal. Different models have additional features such as multiple cleaning modes, pressure sensors, Bluetooth connectivity, and real-time feedback on brushing habits. The toothbrushes also have unique, dentist-inspired round brush heads with a special CrossAction bristle design that pulsates to break up plaque and then rotates to sweep it away.
The iO Series, for example, delivers a professional clean feeling with its Interactive Color Display, Smart Modes, and Smart Pressure Sensor. It covers every tooth surface and all 16 zones of your mouth with AI Recognition and 3D Tracking. The iO5, available in Blush Pink, offers a $40 discount.
The iO toothbrush also features iO Magnetic technology, which combines micro-vibrating bristles with Oral-B's dentist-inspired round brush head. The pressure sensor displays red when brushing too hard, white when brushing too light, and green when the pressure is just right, helping to protect gums. The toothbrush also has a 2-minute timer and can be paired with the Oral-B app to provide personalized brushing intelligence.

ADA-acceptance criteria
The American Dental Association (ADA) has specific criteria that electric toothbrushes must meet to receive their Seal of Acceptance. The ADA Seal of Acceptance indicates that a toothbrush is both safe and effective at removing plaque and reducing gingivitis.
To earn the ADA Seal of Acceptance, electric toothbrushes must pass a series of rigorous ADA laboratory tests and meet dental standards set by the ADA and the American National Standards Institute (ANSI). These tests evaluate qualities like electrical safety, tuft retention, mechanical strength, and chemical resistance. In addition, toothbrush manufacturers must submit safety testing certifications, provide claims of safety and efficacy, and include instructions for use.
The ADA also requires electric toothbrushes to complete clinical studies demonstrating their safety for use on oral hard and soft tissues and dental restorations. These studies must show that the toothbrush can be used without supervision by an average adult to achieve a significant decrease in mild gum disease and plaque over a 30-day period. The ADA Council on Scientific Affairs carefully evaluates the scientific evidence provided by manufacturers according to objective requirements.
The ADA Seal of Acceptance was founded in 1931 to help consumers find safe and effective oral health care products. By meeting the stringent ADA-acceptance criteria, electric toothbrushes can assure consumers that they have been objectively evaluated for safety and efficacy by an independent body of scientific experts.

ADA Seal of Acceptance
The ADA Seal of Acceptance is the gold standard for evaluating the safety and efficacy of dental products. It has been the leading mark of dental product safety and efficacy since 1931. The American Dental Association (ADA) Council on Scientific Affairs evaluates products based on objective requirements to determine if they meet the ADA's rigorous standards.
To earn the ADA Seal of Acceptance, powered toothbrushes undergo a series of tests based on ANSI/ADA standards. These tests assess qualities like electrical safety, tuft retention, mechanical strength, and chemical resistance. Additionally, toothbrushes must demonstrate clinical safety and effectiveness and meet the dental standards of the ADA and the American National Standards Institute.
The ADA Seal of Acceptance is not limited to toothbrushes; it also applies to other dental products such as toothpaste and mouth rinses. These ADA-accepted products meet U.S. and international safety standards, including pH levels. The Seal is awarded for a five-year period, and companies must submit updated chemical and safety data if the product composition changes during this time.
Oral-B electric toothbrushes are among the few that have received the ADA Seal of Acceptance. Their toothbrushes feature 3D Cleaning Action technology, which provides superior plaque removal and helps prevent and reduce gingivitis. The Bitvae Smart Electric Toothbrush is another ADA-accepted toothbrush, recognised for its safety and efficacy in removing plaque and improving gum health.

ADA recommendations for brushing
The American Dental Association (ADA) recommends brushing teeth twice a day for two minutes using a fluoride toothpaste. Brushing for two minutes has been shown to achieve clinically significant plaque removal, and the use of a toothpaste containing fluoride helps to decrease the risk of caries and aids in the remineralization of teeth. ADA recommends using a toothbrush with soft bristles as it helps to minimize the risk of gingival abrasion.
ADA also suggests placing the toothbrush against the gum line at a 45-degree angle to remove plaque from above and just below the gum line. The brush should then be moved gently back and forth in short strokes. To clean the inside surfaces of the front teeth, the brush should be tilted vertically and several up-and-down strokes should be made.
ADA recommends cleaning between teeth once daily to remove plaque and food particles from between the teeth and under the gum line. It also recommends eating a balanced diet that limits sugary beverages and snacks.
The ADA Seal of Acceptance is a guide to consumer dental care products. To earn the Seal, a powered toothbrush goes through rigorous tests based on the ANSI/ADA standards for testing powered toothbrushes. These tests evaluate qualities like electrical safety, tuft retention, mechanical strength, and chemical resistance. The Seal program also requires powered toothbrushes to complete a clinical study demonstrating that they are safe for use on oral hard and soft tissues.

ADA-approved toothbrushes
The American Dental Association (ADA) has approved several electric toothbrushes that meet their rigorous standards for safety and efficacy. Oral-B was the first brand to have its electric toothbrushes accepted by the ADA. The following Oral-B toothbrushes are ADA-approved:
- Oral-B Pro 1000: This toothbrush has a competitive price, cleaning power, a brush timer, an oscillating head, soft bristles, and affordable replacement brush heads. It also has a two-minute timer that signals you to move mouth quadrants every 30 seconds.

- Oral-B CrossAction: This toothbrush has a unique dentist-inspired round brush head with a special CrossAction bristle design and 3D Cleaning Action technology that pulsates to break up plaque and then rotates to sweep it away.
Other ADA-approved toothbrushes include:
- Bitvae Smart Electric Toothbrush: This toothbrush has been deemed safe and effective in removing plaque and preventing and reducing gingivitis when used as directed.
- Quip Sonic: This is a basic, ADA-approved battery-powered brush that uses a single AAA battery that needs to be replaced about every three months. It has a combination of soft bristles and rubber fingers to effectively brush the contours of your teeth, and it also has a two-minute timer and a pressure sensor.
It is important to note that while ADA approval indicates that a toothbrush is safe, effective, and of high quality, it is not necessary for maintaining oral health. The ADA emphasizes that the critical factors for oral health are brushing for two minutes with a reasonably soft brush and using the proper technique.
