Dentist Review

The Philips Sonicare ProtectiveClean 5100 electric toothbrush is designed to effectively clean your teeth and gums.

Brushing your teeth is a breeze, with high-quality bristles that remove plaque and improve gum health. In fact, according to Philips Sonicare, it’s up to 100% better than a manual toothbrush.

After testing it out for multiple days, I particularly appreciated the three unique brushing modes it offers.

My favorite was the Gum Care mode paired with the G2 brush head, which provided exceptional cleaning for my teeth and gums.

However, I would have appreciated brush handle grips to prevent slipping and a tongue cleaner to further enhance my oral hygiene routine.

The BrushSync technology is another feature that makes the Sonicare 5100 electric toothbrush enjoyable to use. The toothbrush uses sensors to track how long you have been using the brush head and how hard you are brushing.

Then, when it’s time to replace the brush head, the toothbrush will alert you with a light on the handle. This ensures that you always use an effective brush head that is not worn out.

Overall, the Philips Sonicare ProtectiveClean 5100 electric toothbrush is an effective tool for improving your oral health.

With its sonic technology, three cleaning modes, BrushSync technology, and pressure sensor, you can be confident that you get a thorough and effective clean every time you brush.

What’s the Difference Between 5100 & 5300?

The Philips Sonicare ProtectiveClean 5100 and 5300 are both high-quality electric toothbrushes, but there are some differences to consider when choosing between them.

The primary distinction lies in the brush head options and pricing. The Sonicare 5300 offers three brush heads: one G2 and two W brush heads, providing greater versatility and customization for your oral care routine.

On the other hand, the Sonicare 5100 comes with a single G2 brush head, making it more suitable for users with basic oral care needs.

As a result of the additional brush heads, the Sonicare 5300 typically carries a higher price tag than the 5100 model.

When selecting between the two, consider your specific requirements and preferences. If you desire more brush head options for a tailored cleaning experience, the 5300 may be the better choice, despite the slightly higher cost.

However, if you are looking for a more budget-friendly option that still delivers excellent oral care, the Sonicare 5100 remains a solid choice.
