Maintaining good oral health is easy with the PAZ Generix heads for Philips Sonicare ProResults Standard toothbrush heads. Designed to work with multiple Sonicare models, these snap-on replacement brush heads feature a large surface area and radial-trimmed, contoured bristles to thoroughly clean and massage teeth and gums. Angled Bristles Cover Larger Surface Area The curved surface area created by the brush head's radial-trimmed bristles help you maintain contact with the surfaces of the teeth and gums as the brush head pivots. The bristles' contoured pattern fits the natural shape of your teeth. Peaks and valleys along the length of the brush head are ergonomically designed to fit between teeth, so you're less likely to miss places when you brush. This means you can remove more disease-causing plaque for a healthier mouth. Replace Every Three Months You can't see it, but your brush head wears over time. Dental professionals recommend replacing your brush head every three months. Sonicare technology helps you remove more plaque than a manual toothbrush. Fits Multiple Sonicare Handles The PAZ Generix for ProResults brush head works with the following Sonicare models: DiamondClean, FlexCare+, FlexCare, HealthyWhite, and EasyClean. The heads easily snap onto handles and come with caps for hygienic storage and travel.
