Comment on Dyson CameraJet: The only toothbrush with a camera and a jet

Comments

Someone should've been more thorough when they prepped this for release.

I read all of that text. When I got to the part about their mouthwash (rinse) I found xylitol hyped as part of the disinfection regime. Xylitol was just tagged, again, in the literature as a source of cardiac issues and notes were that it was a common ingredient in chewing gum and mouthwash. The risks have been known for several years as documented here [0]. A recent article is this one [1]

After reading all of this I feel like Dyson should consider modifying the composition of their mouthwash to reduce the risk of users ingesting xylitol during or after this process. There are other synthetic sweeteners, each with its own set of problems but xylitol was commonly employed because it had antibacterial effects on bacteria that are known to cause gingivitis. Its use in chewing gum and in some foods probably caused most of the exposure events for people looking at healthier options for common items. Most people don't swallow mouthwash or toothpaste but there will always be some remaining in the mouth that is flushed into the system after brushing.

I checked their "Caveats and Sources" section at the end of the article. If you notice, there are 10 items in that list. When you read the article, there are only 8 tags linking to the Caveat list. Numbers 9 and 10, both related to MyDyson app (9) and claims associated with Dyson mouthwash and how the comparison was made (10) are not found in the text.

I find the whole device intriguing. Anything to simplify the tooth maintenance process and improve it works for me. I like that they attacked the tooth gap issue in an effort to minimize the need for mechanical flossing. I'm not sold on cameras on a toothbrush but if it works, I could be though I do not want a device like this to be connected to any other device that could have access to outside networks. It all needs to work in a self-contained system at point-of-use with data leakage, ever. Dyson doesn't need to learn to improve their devices by aggregating my teeth-brushing activity with that from millions (or thousands, or hundreds if it ever happens) of users. Pay people to participate. Use that data.
