Question about Philips Sonicare W2 Optimal Black

The W2 Optimal White brush heads have a medium degree of hardness, while the C3 Premium Plaque Defence brush heads are also medium-hard. For sensitive gums, the C3 brush heads are a good choice due to their slightly angled shape and the ability to clean hard-to-reach areas. They provide a gentle and thorough clean that is suitable for sensitive teeth and gums.

The main differences between the two brush heads are:

- Cleaning efficiency: the C3 removes up to 10 times more plaque than a manual toothbrush, while the W2 specialises in removing discolouration.
- Objective: The W2 is ideal for removing discolouration and provides bright white teeth, while the C3 focuses on plaque removal.
- Brush shape: The C3 has a slightly angled shape that reaches hard-to-reach areas better.
