If you use a Philips Sonicare electric toothbrush, you know that eventually, you’ll need to replace the brush heads. But with options like the Sonicare C2 and C3 replacement heads, how do you choose?
In this guide, we’ll compare the Philips Sonicare C2 and C3 brush heads side-by-side. I’ll overview the key differences and similarities to help you decide which brush head is right for your Sonicare toothbrush model and oral health needs.
Philips Sonicare offers a wide variety of electric toothbrush heads that are specifically designed and tested to work with Sonicare toothbrush handles. Two of their most popular options are the C2 and C3 brush heads.
As I explain in my guide to the best Sonicare brush heads, Philips Sonicare uses descriptive names to indicate what each brush head is designed for. For example:
- C stands for Clean — fighting plaque
- G stands for Gum — gentle gum stimulation
- W stands for White — removing surface stains
- P stands for Power — deeper cleaning for gingivitis
The number then indicates if it is from the lower-end 100/200 series (1), mid-range 300/700 series (2) or highest-end DiamondClean/900 series (3).
Keep this naming convention in mind as we look at how the C2 and C3 differ.
The Philips Sonicare C2 Optimal Plaque Control brush head is designed to deliver exceptional daily cleaning and plaque removal.
The contoured bristles are angled to effectively disrupt and sweep away plaque. This brush head is compatible with mid-range Sonicare models like the Philips Sonicare 3 Series and HealthyWhite+.
Key Features and Benefits:
- Contoured bristle design to enhance plaque removal
- The angled base of bristles reaches between teeth
- Designed to optimize the performance of mid-range Sonicare models
- Screw-on design for easy replacement
- Provide a gentler clean for sensitive teeth
The C2 brush heads tend to be slightly less expensive than the C3 models. So the C2 is a great option if you want quality plaque removal without paying a premium for some of the more advanced brush heads.
The Philips Sonicare C3 brush head takes plaque removal to the next level. This brush head is engineered to work with the highest-end DiamondClean Smart and other advanced rechargeable Sonicare models.
It features extra-long bristles to give you that deep clean feel while disrupting plaque in hard-to-reach areas. The densely-packed central stain removal bristles also boost your brushing effectiveness.
Key Features and Benefits:
- Extra-long bristles for maximized plaque removal
- Densely packed central stain removers
- Contoured profile aids with maneuverability
- Designed for top-of-the-line Sonicare models
- Provides that invigorating deep clean feel
- Screw-on for easy replacement
The C3 brush heads utilize premium materials and an advanced bristle arrangement to deliver exceptional cleaning power.
Now let’s break down the C2 and C3 brush heads side-by-side to understand the key differences and similarities:
Feature Comparison:
Cleaning Focus:
- Sonicare C2 Brush Head: Plaque removal
- Sonicare C3 Brush Head: Plaque removal
Bristle Design:
- Sonicare C2 Brush Head: Angled base
- Sonicare C3 Brush Head: Extra long
Compatibility:
- Sonicare C2 Brush Head: Mid-range models
- Sonicare C3 Brush Head: High-end models
Central Bristles:
- Sonicare C2 Brush Head: Regular density
- Sonicare C3 Brush Head: Densely packed
Price:
- Sonicare C2 Brush Head: $$
- Sonicare C3 Brush Head: $$$
In summary:
- Both provide exceptional plaque control, the core focus of the “C” brush heads
- The C3 uses extra long bristles and denser stain removers for enhanced cleaning power
- C2 works with mid-range Sonicare models while the C3 is optimized for premium models
- The advanced C3 brush heads come at a higher price point
So if you have a lower or mid-priced Sonicare, the C2 is likely the ideal replacement head. But if you own a DiamondClean Smart or other premium Sonicare, consider stepping up to the C3 for maximum plaque-fighting capability.
Before choosing replacement brush heads, it’s helpful to understand why they need regular replacement in the first place.
Over months of normal use, electric toothbrush heads wear down as the bristles fatigue. This degrades their ability to clean effectively. My tips for brush head care can extend their lifespan slightly, but replacement is inevitable.
Philips Sonicare recommends swapping out brush heads at least every 3 months. But there are a few signs that indicate it’s time for a new brush head:
- Frayed or splayed bristles
- Reduced vibration/motion
- Less effective cleaning
- The brush head feels loose on the handle
Replacing your Sonicare brush head routinely is key to experiencing the full cleaning and performance benefits. Don’t wait until brushing feels ineffective. Be proactive with your brush head replacements.
When purchased individually, Philips Sonicare replacement brush heads range from $$-$$$. But you can save money buying brush heads in packs of 2, 3 or 4 replacements:
I recommend buying packs for convenience and maximizing savings. Consider mixing up your brush heads — trying both C2 and C3 — to find your ideal blend of affordability and cleaning power.
Choosing between the Philips Sonicare C2 and C3 ultimately depends on your specific toothbrush model and bristle preference. Ask yourself:
- Do I have an entry-level or mid-range Sonicare? → C2
- Do I own a DiamondClean, 9000, or other premium Sonicare? → C3
- Am I satisfied with my current plaque removal? → C2
- Do I want to boost plaque-fighting performance? → C3
- Is maximizing savings a priority? → C2
- Am I willing to pay more for advanced features? → C3
Evaluate your priorities to select the right replacement head. Both the C2 and C3 deliver exceptional Sonicare cleaning — it’s just a matter of which level fits your needs and budget.
To recap, the key differences between the Philips Sonicare C2 and C3 brush heads are:
- Designed for different Sonicare models
- Bristle arrangement and plaque fighting performance
- Price point
No matter which you choose, proper brush head hygiene and replacement every 3 months help ensure you get the most from your Philips Sonicare electric toothbrush.
