ORAL-B 1.2.3 CLASSIC MEDIUM / 40 TOOTHBRUSH

Product classification

Generic category: Manual medium-bristle toothbrush
Brand: Oral‑B Official Website
Product name: Oral-B 123 Medium 40 Toothbrush
Intended population: Adults and adolescents requiring routine daily plaque removal and oral hygiene maintenance.

Medical/device description

The Oral-B 123 Medium 40 Toothbrush is a manual oral hygiene device intended for mechanical removal of dental plaque, food debris, and superficial stains from tooth surfaces. The toothbrush incorporates medium-firmness bristles with auxiliary cleaning elements designed to improve access to difficult-to-reach areas and enhance cleaning performance during routine daily use.

Structural characteristics

1. Medium bristle configuration

• Uses medium-firmness nylon filaments
• Intended to provide a balance between cleaning efficiency and brushing comfort
• Designed for routine plaque removal from enamel surfaces

Medium bristles generally provide stronger mechanical cleaning than soft variants but may exert greater force on gingival tissues if excessive pressure is used.

2. Power Tip / extended bristle design

• Longer bristles positioned near the brush tip
• Intended to:
  • improve access to posterior teeth
  • reach interdental spaces
  • clean difficult areas along gingival margins

These bristles assist in reaching regions often missed during standard brushing.

3. Indicator bristles

• Blue-colored indicator filaments gradually fade with repeated use
• Intended to indicate loss of optimal cleaning efficiency and replacement timing

Recommended replacement usually occurs when approximately half of the indicator color fades or after about 3 months of use.

4. Tongue cleaner

• Integrated textured cleaning surface
• Intended to:
  • remove tongue debris
  • reduce odor-causing bacterial accumulation
  • improve breath freshness

Tongue cleaning can contribute to reduction of oral malodor.

5. Polishing cup technology

• Specialized cup-shaped cleaning component designed to retain toothpaste around tooth surfaces
• Intended to:
  • remove superficial stains
  • improve polishing action
  • contribute to cosmetic tooth brightness

This effect primarily targets extrinsic stains rather than intrinsic discoloration.

6. Ergonomic control grip

• Non-slip handle structure
• Intended to:
  • improve control during brushing
  • reduce hand fatigue
  • facilitate stable brushing movements

Mechanism of action

The toothbrush functions by mechanical disruption and removal of oral biofilm.

Mechanisms include:

1. Disruption of plaque adherent to enamel
2. Removal of trapped food particles
3. Reduction of bacterial accumulation near gingival margins
4. Removal of superficial tooth stains
5. Reduction of tongue bacterial load

Routine plaque reduction may contribute to prevention of:

• dental caries
• gingivitis
• halitosis
• progression of periodontal disease

Claimed functional benefits

Manufacturer and retailer descriptions indicate that the device may:

• Improve daily plaque removal effectiveness
• Reach difficult-to-clean posterior and interdental regions
• Assist with removal of surface stains
• Improve breath freshness through tongue cleaning
• Provide visual indication for toothbrush replacement timing

Directions for clinical use

Recommended use:

• Apply fluoride toothpaste to bristles
• Position toothbrush approximately 45° toward gingival margin
• Use gentle circular or short sweeping movements
• Brush:
  • outer tooth surfaces
  • inner tooth surfaces
  • chewing surfaces
  • tongue surface
• Brush for approximately 2 minutes twice daily

Avoid excessive horizontal scrubbing force because force rather than brushing frequency is a major factor associated with enamel abrasion and gingival recession.

Precautions

Use cautiously in patients with:

• gingival recession
• dentin hypersensitivity
• active periodontal inflammation
• recent oral surgery

Because this is a medium-bristle toothbrush, individuals with sensitive gingiva or existing recession may often tolerate soft-bristle variants better.

Replace the toothbrush approximately every 3 months, or sooner if bristles become distorted or indicator bristles fade.
