ORAL-B 123 MEDIUM TOOTHBRUSH (HERO DESIGN)

ORAL-B 123 MEDIUM TOOTHBRUSH (HERO DESIGN)

PRIMARY USES

1. Superior Plaque Removal with Cavity Defence Bristle Technology
Primary Use: Features a unique cavity defence bristle design with tightly packed centre bristles encircled by taller angled ones, creating a polishing cup effect that reaches between teeth and along the gum line to help protect against cavities, removing significantly more plaque than a standard flat-trim toothbrush .
How it helps: For the dentist and dental hygienist, interdental spaces and the gingival margin are the primary sites where carious lesions initiate. The cup-shaped bristle configuration is specifically designed to envelop each tooth, cleaning from multiple angles simultaneously to disrupt bacterial biofilm in these high-risk areas . The tightly packed centre bristles provide thorough cleaning power, while the taller angled outer bristles flex to penetrate tight spaces between teeth . For the patient, this means a manual toothbrush that actively reaches the areas most prone to decay, providing superior cavity protection with every use.

2. Polished, End-Rounded Bristles for Enamel and Gum Safety
Primary Use: Medium bristles feature polished, end-rounded tips that deeply penetrate hard-to-reach areas and effectively clean along the gum line while remaining gentle on tooth enamel and gum tissue, with the unique tuft design including both flagged (split-end) and end-rounded filaments for optimal cleaning action .
How it helps: For the dentist advising patients on toothbrush selection, bristle design must balance cleaning efficacy with safety. Hard or unpolished bristles risk enamel abrasion and gingival trauma over time, particularly if patients brush aggressively. The Oral-B 123 incorporates a scientifically designed tuft configuration: tufts of the first type have a smaller cross-sectional area (1.4mm diameter) with flagged (split) filaments for plaque penetration, while tufts of the second type have a larger cross-sectional area (2.8mm diameter) with end-rounded filaments for gentle gum cleaning . The larger diameter tufts have a chamfered upper surface angled toward the handle by approximately 15.5-16 degrees, enhancing comfort along the gum line . For the patient, this means a toothbrush that effectively cleans while remaining safe for daily use.

3. Oval Brush Head for Access to Posterior Teeth
Primary Use: Features an oval-shaped brush head specifically designed to help access and clean posterior teeth (molars), which are often the most difficult areas to reach during routine brushing and are high-risk sites for interproximal decay .
How it helps: For the dental professional, the distal surfaces of the last molars and the posterior interproximal spaces are the most frequently missed areas during brushing, making them the most common sites for new carious lesions. The oval brush head design allows for better manoeuvrability in the narrow confines of the posterior oral cavity, reaching behind the back teeth to clean areas that standard rectangular brush heads cannot access effectively . For the patient, this means thorough cleaning of the teeth furthest back in the mouth—areas often missed even by diligent brushers.

4. Textured Tongue Cleaner for Fresher Breath
Primary Use: Features an integrated textured tongue cleaner on the back of the brush head designed to remove odour-causing bacteria from the tongue surface, significantly reducing oral malodor and leaving breath feeling fresh .
How it helps: For the general dentist addressing patient complaints of halitosis (bad breath), the tongue dorsum is a primary reservoir of volatile sulfur compound (VSC)-producing bacteria that cause oral malodor. Standard brushing does not address the tongue. The integrated tongue cleaner allows patients to brush their tongue immediately after brushing their teeth without needing a separate tool . This removes bacterial biofilm from the tongue surface, tackling halitosis at its source. For the patient, this means fresher breath and a more complete-feeling clean in a single integrated tool.

5. Blue Indicator Bristles for Optimal Replacement Timing
Primary Use: Features blue Indicator bristles that fade halfway with use, providing a visual cue that signals precisely when the toothbrush needs to be replaced for optimal cleaning performance, typically every 3 months .
How it helps: For the dentist and dental hygienist, patient compliance with the recommended 3-month toothbrush replacement schedule is notoriously poor. Worn bristles are significantly less effective at removing plaque and can harbour more bacteria. The Indicator bristles fade halfway, removing the guesswork—when the blue colour has faded, it is time to replace the brush . Dentists recommend replacing your toothbrush every 3 months, or when bristles are faded and worn, for a better clean . For the patient, this means a simple, visual reminder to change their toothbrush at the optimal time for maximum cleaning effectiveness.

SECONDARY USES

1. Post-dental hygiene maintenance between professional cleanings: For patients in the recall interval between professional dental cleanings, the cavity defence bristle configuration and oval head design help maintain low plaque levels and healthy gingiva by cleaning interdental and posterior areas effectively, supporting the results of professional prophylaxis.

2. Orthodontic patient oral hygiene (braces): For patients undergoing orthodontic treatment with fixed braces, the oval brush head and cup-shaped bristle design help clean around brackets and wires, reducing the risk of white spot lesions and decalcification during orthodontic treatment.

3. Charcoal-infused variant for additional stain removal: The hero design is also available in a black charcoal-infused variant (Cavity Defense Black), where charcoal extract in the bristles helps remove surface stains for a brighter smile while providing the same cavity defence benefits .

4. Periodontal maintenance phase support: For patients in the maintenance phase following non-surgical periodontal therapy, the polished, end-rounded bristles help maintain gingival health by disrupting subgingival bacterial recolonisation between maintenance visits while remaining gentle on healing gum tissues.

5. Travel and everyday use for adults seeking professional-grade manual brushing: The durable construction and classic 123 design make this toothbrush suitable for daily home use and travel, providing professional-grade cleaning without batteries or charging, available in multiple colour variants including green, red, purple, and blue .
