Standard Size
Medium Bristles
Black Colour

Up to 10x more plaque removal than a manual toothbrush

And thanks to its flexible design, it removes up to 10x more plaque from hard-to-reach areas* for a truly deep clean along the gum line and between teeth.

Up to 4x more surface contact** for an effortless deep clean

You get a personalized clean every time you brush with our adaptive cleaning technology. Soft rubber sides flex to let C3 Premium Plaque Defense adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing our sonic cleaning power. Bristles can then adjust to the shape of your teeth and gums so you get up to 4x more surface contact than a regular brush head** for deeper cleaning in hard-to-reach areas.

Automatically selects optimal mode for ultimate results**

You’ll always get the best possible clean with our BrushSync™ mode-pairing feature**. The Philips Sonicare C2 Optimal Plaque Defense brush head syncs with your BrushSync™ enabled Philips Sonicare toothbrush handle**, selecting the optimal brushing mode and intensity level for exceptional cleaning. All you need to do is start brushing.

Philips Sonicare’s advanced sonic technology

Philips Sonicare’s advanced sonic technology pulses water between teeth, and its brush strokes break up plaque and sweep it away for an exceptional daily clean.

Always know when to replace. Always get an effective clean.

Brush heads become less effective after 3 months of use, but with BrushSync™ you’ll be reminded before this happens. Your smart toothbrush will track how often and how hard you brush, and will notify you when it’s time for a replacement. Don’t have a smart Philips Sonicare toothbrush? Just monitor your blue replacement bristles, and when they turn white you’ll know it’s time for a fresh brush head.

Tested to meet your oral health needs

All Philips Sonicare brush heads are safe and gentle on teeth and gums. During tests, each brush head is put through its paces to ensure durability and an exceptional performance every time you brush.

Click-on design for simple brush head placement

They make it easy to choose the right solutions for my teeth and without the hassle of visiting my dentist every time. If you’re looking for the best products and super convenient delivery, definitely check out The House of Mouth. It’s made my oral care routine way easier, plus more affordable.

The whitening gel I buy from The House of Mouth is the holy grail, I have never received so many compliments on how white my teeth are. Always an easy and quick transaction and honestly, their customer service is out of this world. Wouldn’t shop anywhere else!

I recently had a Telehealth appointment to discuss teeth whitening products, and it was a fantastic experience. The process was incredibly convenient, allowing me to connect with a dental professional from the comfort of my home. The appointment was easy to schedule too. During the consultation, the person was attentive and knowledgeable, answering all my questions and providing personalised recommendations based on my dental history and goals. They took the time to explain the pros and cons of different whitening products and methods, ensuring I felt confident in my decision. I appreciated the thoroughness and professionalism of the entire experience. It was clear that my dental health and satisfaction were top priorities. I now have a clear plan for achieving a brighter smile, and I couldn’t be happier with the guidance I received. Highly recommend this Telehealth service

My personal experience at House of Mouth has been incredibly positive. I'm always nervous and sceptical when it comes to anything relating to my health. I had tried the teeth whitening through my own amazing dental practice, but I was looking at increasing the strength of the gel and time was an issue for me. I was attracted to the House of Mouth on Facebook, and after researching the company, and speaking with Daniel, I felt very much at ease and knew that the House of Mouth was a genuinely honest and professional company. Every question I had, was answered very quickly by either Daniel or a member of the Team. I was also interested in renewing the whitening trays, and I couldn't believe how easy and stress-free the whole procedure was. The package I received had step-by-step instructions and before I knew it, I had my new trays. I believe what impressed me the most was the support I received, and believe me, it's ongoing. The House of Mouth definitely has that good old fashioned customer service, and I'm so thrilled with the results I'm getting. You can trust the House of Mouth and I highly recommend them.

Amazing customer service (particularly from Lynsey Fairhurst)I ordered from HoM recently and the Aramex delivery guy stupidly threw my parcel behind the wheel of my house mate’s car. He accidentally ran over my parcel not realising.I messaged HoM to see if they were able to get any compensation from Aramex and they weren’t able to but Lynsey still very kindly sent my parcel out again.Really generous and understanding. My first time ordering from HoM and I’m really impressed with the quality of the whitening gel and their customer service.

Have an auto-immune problem with my mouth which results in constant horrendous dry mouth, waking me at least 4-6 times during the night with no saliva, mouth like the desert. Bought first pack of XyliMelts Dry mouth melts - absolute life saver. Have been able to sleep through the night using them and am using them during the day as well. Brilliant product

I have been extremely happy with the excellent customer service from Daniel and Jasmyn. They helped me sort a postage issue simply and quickly and were very friendly, polite, and professional. They took lots of care with follow up emails too which I appreciated. The mint Xylimelt discs arrived quickly and were packaged really well. I will definitely keep dealing with House of Mouth from now on and highly recommend them.Thanks,Andrew :-)

So these guys are actually amazing to deal with. Super informative when you call up. I even did a click and collect order and they did a courtesy call to make sure I picked the right option to pick up instead of delivery. Absolutely no wonder they have a perfect 5-star rating.

I have ordered teeth whitening gel from here and their assistance was professional and extremely helpful. I then ordered new custom moulds of my teeth and the process was well explained and the service was prompt. I'm so pleased with House of Mouth, and will only order from them in the future. They're really that good!

My dentist did not provide a full amount of whitening gel to get through 30 days treatment. The cost of an extra gel from my dentist was high. I looked online and found THE HOUSE OF MOUTH. I ordered three extra gel syringes for the price of one from the dental surgery. Identical products 1/3 of the cost - WOW... THE HOUSE OF MOUTH has a great website and 5 STAR service. Thanks to all at THE HOUSE OF MOUTH.

I don't normally write reviews, but am making an exception for House of Mouth. The reason is that they provide a top notch service at a cost far less than you'd pay at the dentist. It costs a bundle to get a dentist to make those bleaching trays to whiten your pearlies. House of Mouth will do a perfect job for way less. And you don't have to go into an appointment - you can do it all by mail. Dan is lovely to deal with. And the whole process is easy.

Great products, fantastic prices and fabulous service from support staff, I had a issue on how to use a product that I had purchased and sent an email, I received a telephone call within a couple of hours and Daniel was so patient, I have spoken to a couple of telephone support staff and they are so nice,house of mouth is lucky to have such friendly and knowledgeable people.I would not purchase from anywhere else.You will go to house of mouth for their range and price but you will stay for their sales and support service.

My experience so far has been exceptional!I spoke with Daniel twice over the phone before ordering and he was patient and extremely informative in answering my wide array of questions. I received the whitening pack after just one day (express post) and I have already done my moulds and sent it back, let’s see what the results are from here!!

Thanks again for your dedication to customer satisfaction!
