Q: Can the Diamond Clean W3 replacement heads be used with this model?

A: Yes. All of the bush heads can be used on the Sonicare 9900 Prestige

Q: Is this brush water resistant enough to use in the shower?

A: Hello! It is completely safe to use your Philips Sonicare Toothbrush in the shower. Make sure to never store your Philips Sonicare Toothbrush in the shower between brushings. Allow the toothbrush to air-dry between uses. Also, do not place the charger where it might risk contact with water.

Q: Is there any way to see what % battery is remaining on the brush? Or do you have to use the app? Is there any indicator that there is low battery?

A: Hello! The Philips Sonicare Prestige HX9990/12 toothbrush does not display the exact percentage of battery directly on the toothbrush. However, here's how it works: Solid white light, battery is fully charged. It blinks white, partially full. Blinks amber, and the battery is low prompting you to charge it soon.

Q: Where do you buy the matching color replacement brush heads?

A: High Sarah. I will answer this question really quickly for you. No matching brush heads. I have the navy blue toothbrush and I recently ordered new brush heads from the actual Philips website, and nope, only black or white brush heads is what they offer. So I have a navy blue handle and a black brush head.

Q: Does this model sense tongue brush heads and adjust the mode for tongue care?

A: Hello there! Thank you for your question. The Philips Sonicare 9900 Prestige HX9990/12 with SenseIQ works with several Sonicare brush heads, including the TongueCare+ tongue brush. While it recognizes standard brush heads, it doesn't automatically detect the TongueCare+ head or switch to a tongue-cleaning mode. To clean your tongue, simply attach the TongueCare+ head and manually select the TongueCare mode on the handle.

Q: Is the champagne one with gold accents or rose gold? The same gold as the black one?

A: Hello there! The Philips Sonicare 9900 Prestige Rechargeable Electric Toothbrush in the Champagne color features gold accents. Both the Champagne and Midnight versions share the same gold accents.
