Without further information or context, it is impossible to determine if the old Philips Sonicare is broken. It would be best to inspect the toothbrush for any visible damage or malfunctioning parts. If the toothbrush is not working properly, it may need to be repaired or replaced. **

The Philips Sonicare Smart may not be able to connect to the app due to several reasons. It could be due to a compatibility issue with the device's operating system or software version. Additionally, there may be a problem with the Bluetooth connection between the toothbrush and the app. It is also possible that there is a temporary issue with the app's servers or the toothbrush itself. Troubleshooting steps such as restarting both the toothbrush and the app, ensuring they are both updated to the latest versions, and checking for any Bluetooth interference may help resolve the connection issue. **

The Philips Sonicare uses high-frequency vibrations and sonic technology to create a dynamic cleaning action that effectively removes plaque and tartar from the teeth. The rapid movement of the bristles helps to break up and dislodge plaque and tartar, preventing them from building up and causing discoloration. This thorough cleaning action helps to maintain whiter teeth by preventing the accumulation of stains and discoloration caused by plaque and tartar. Additionally, the Sonicare's gentle yet effective cleaning action helps to prevent gum disease and promote overall oral health, contributing to a brighter and healthier smile. **

I would recommend the Philips Sonicare DiamondClean Smart 9700. It has advanced features such as multiple cleaning modes, a pressure sensor, and a smart brush head recognition system.

Black Friday deals can be a mix of real bargains and fake discounts. Some retailers may inflate the original prices to make the discounts seem larger than they actually are. It's important for consumers to do their research and compare prices before making a purchase to ensure they are getting a genuine deal. Additionally, some products may be older models or lower quality items that are being sold at a discounted price, so it's important to consider the value and quality of the product before making a purchase. **
