A toothbrush supports Periodontal Disaease

Dee-Dee 28 June 22, 2026

[This review was collected as part of a promotion.] The DiamondClean Smart 9300 has truly impressed me with its powerful cleaning performance. Its C3 replacement brush head removes plaque effectively and leaves no residue on my teeth. The adjustable cleaning modes are well designed and easy to use, making daily brushing simple and comfortable. Because I have been diagnosed with periodontal disease, this electric toothbrush has been a real benefit to my oral‑health routine. I highly recommend the DiamondClean Smart 9300 for anyone managing periodontal disease and seeking a deeper, more effective clean.

Model 9300 Diamond Clean Rates a 10+

Light Doctor June 19, 2026

[This review was collected as part of a promotion.] I have used a different Sonicare toothbrush model for about five years and decided to upgrade to the #9300 Diamond Clean model. I am very pleased and wish I had upgraded sooner! This Sonicare Model 9300 with the accompanying App work very well together. Through the App, I have been able to correct many of my old brushing habits where I was not brushing my teeth properly and holding my toothbrush correctly. The App and Sonicare working together is Amaxing! I highly recommend the Model 9300 Diamond Clean!

It has improved my teeth on a per use basis

Candaceangel83 May 10, 2026

[This review was collected as part of a promotion.] It has been great in cleaning my teeth, whitening my teeth and also overall health of my teeth. Well worth the money for the device

Great but gimmicky

Queen Suzy July 15, 2026

[This review was collected as part of a promotion.] This brush is still a bit aggressive but I am getting used to it. I just hope it will not cause abrasion lesions on my teeth at the gumline. I feel like the mechanisms on the brush could be simplified. There are different levels of intensity labeled in a way that I have no idea how the levels are different one from another. I also feel like Phillips caters too much to public opinion by labeling brush heads as "medium" when they aren't and medium brush heads should never be used. Just be honest with consumers relabeling something to give us what you think we want.

Not a good choice for me.

AZretired1 March 18, 2026

[This review was collected as part of a promotion.] Unfortunately for me this DiamondClean Smart 9300 HX9903/65 Rechargeable Toothbrush doesn't do the trick.I stopped using my current brand brush to start with this because the bush head seemed smaller and more of a better fit for my mouth. After using the DiamondClean Smart 9300 HX9903/65 Rechargeable Toothbrush for a little over a month, I went for my cleaning and my hygienist asked me what happened. My teeth had been doing so much better at my last check up. I explained I switched to the DiamondClean Smart 9300 HX9903/65 Rechargeable Toothbrush from my previous brand and maybe that had something to do with it. Personally for me, my teeth feel better and cleaner with my previous brand. I have always had Phillips Sonicare electric brushes in the past until I changed to the other brand. For my teeth the other brand is better so I will go back to using it and be disappointed I spent so much money on the DiamondClean Smart 9300 HX9903/65 Rechargeable Toothbrush.

Need better QC Process for this model

New England September 1, 2025

[This review was collected as part of a promotion.] It broke and using the site to ask for a replacement brings you through a circular process. Brush head won't attach now. Center component is wiggly and looks like it is not connected somewhere inside. FRUSTRATING. Been using Philips Sonicare products for 15 years. This model is not as well built as previous models.

Sonicare quality has significantly

UNSA1980 June 5, 2026

[This review was collected as part of a promotion.] I thought is was time to replace me 10 year old Sonicare. My new Sonicare couldn't hold a charge to complete one toothbrush cycle. So I'll keep using my old Sonicare until it doesn't work and although I am impressed with my current Sonicare after my recent experience with Diamond care I won't be buying a from Sonicare again

SHAME ON WALMART !!

Liz April 18, 2026

This is a review of Walmart's non-disclosure practices on this purchase, not the product itself. My Sonicare was received with a blue label attached reading, "RESTOCK," and with a bar code and about a 20-digit ID code. This indicates a previously-opened and returned item which was NOT disclosed on the purchase information on the Walmart site; and I only noticed this when I was looking for information on the box after I had opened the boxing and used the product to register it with Philips. There were also other additional labels glued on top of the original boxing labels: Bar codes, etc. Shame on Walmart for such practices!!! I will be writing customer support to request a 3-year extended warranty on this purchase at NO COST TO ME. If it is not honored, I will be filing formal complaints.

This toothbrush arrived used. There was toothpaste around the base of the brush handle. There were no brush heads and the user manual was missing. Since it was sold by a third party seller, Walmart will not accept the return via mail. The closest store requires a car to get to. I do not have a car. The best the agent could do to help me is give me a $10 gift card. I am disgusted with the purchase and very disappointed with Walmart.
