Some heads felt polished and gentle, one wore out fast, and the differences were real. Here is what I found. I also watched for gum irritation and frayed bristles, since a head that hurts your gums or wears out fast is a poor buy at any cost..

Why Philips Sonicare C3 Two-in-one Is Necessary
A toothbrush head is a small purchase with a daily impact. The right head cleans thoroughly, protects your gums, and lasts the full three months without fraying, while a poor head can irritate gums, miss plaque, and wear out in weeks. Since you use it twice a day, the difference between a good head and a bad one adds up fast.
The choice between genuine and compatible heads is really a choice between performance and price. Genuine heads clean better and last longer, while compatible heads cost far less and let you replace them more often. Knowing the trade-off helps you decide based on your budget, your gums, and how often you are willing to replace heads.
Finally, a good head encourages better brushing. When the bristles feel soft and the fit is secure, you brush longer and more thoroughly, and your dentist notices the difference. Choosing well means picking a head that fits your handle perfectly, feels gentle on your gums, and stays effective for the full recommended period.
