Hmm. The article says that after 360 minutes of use, it will tell you to replace. A regular tooth cleaning cycle is 2 minutes. So it’s 4 minutes for morning plus evening. 360/4=90 days..usually I replace my toothbrush head every 2-3 months, and I think this is what dentists also recommend. Why would I ever want to reset this counter?
- I_Am_Nous 3y agoHow long before you are ingesting significant amounts of microplastics from the bristles dissolving?
- resoluteteeth 3y agoIf that's an issue I suppose you could brush your teeth, rinse your mouth, and then use a fluoride mouthwash like act
- contingencies 3y agoIIRC mouthwash has been debunked as a post-brush routine and is better deployed post sugar consumption in lieu of immediate brushing. https://nypost.com/2021/07/13/dentist-warns-to-never-use-mouthwash-after-brushing-teeth/ https://nypost.com/2021/07/13/dentist-warns-to-never-use-mou... https://askthedentist.com/mouthwash-risks-and-alternatives/ https://askthedentist.com/mouthwash-risks-and-alternatives/ https://www.rd.com/article/health-danger-mouthwash/ https://www.rd.com/article/health-danger-mouthwash/
- hnarn 3y agoCategorical statements like these are infuriating. What has been “debunked” is that you should not use mouth wash that has a lower fluoride content than the toothpaste you used right before, or mouth wash that is anti-bacterial. Not all mouthwashes and toothpastes are equal, therefore this categorical statement is wrong, and nothing has been “debunked”. The mouth wash I use is the one recommended by my dentist, it is not anti bacterial and it has 0.2% fluoride. The last article you posted simply lies: > Mouthwash contains an antiseptic compound called chlorhexidine. No it doesn’t. Not all mouthwash contains that. I recognize it though, because it’s what I use as an antiseptic alcohol to clean bruises.
- TheSpiceIsLife 3y agoChlorhexidine isn't an alcohol. Why would a bruise need cleaning? A bruise is always caused by internal bleeding into the interstitial tissues which does not break through the skin.
- c0nsumer 3y agoI think you may be misunderstanding someone who isn't a native English speaker. I believe they, restated, indicated that they are aware of the alcohol content, because they use it to clean wounds to the skin.
- hnarn 3y agoEnglish is indeed not my first language and I wasn’t aware that the definition of a “bruise” required there to be no breaking of the skin, I always thought it just meant a light wound, like you’d get from falling off a bike at low speed. The reason I mentioned alcohol is that chlorhexidine is often combined with alcohol in products used for cleaning wounds, but you are correct, it’s not an alcohol. Regardless, the point of my comment was not on how to properly clean wounds, but that you do not need to rinse your mouth with “wound-cleaners”, not all mouthwashes contain this and that means that the statement that mouthwashes are “debunked” is complete nonsense.
- contingencies 3y agoHey I said IIRC - IANAD. What has been “debunked” is that you should not use mouth wash [...] that is anti-bacterial. Fact: that is approximately all mouthwash. Sure maybe there is some whitening only stuff or other specialist cases, but practically speaking ~everything commonly available as mouthwash is anti-bacterial (source: just checked >20 products at major retailers). It appears that our comprehension is mutual.

- panarky 3y agoThe fact that the device manufacturer profits by selling a replacement part is not evidence that the part does not need replacement.
- drpixie 3y agoBut the fact the manufacturer wants you to replace the part, is not evidence that the part needs to be replaced.
- userbinator 3y agoMicroplastics should be the least of your concerns. You ingest far more reactive substances just from food and breathing.
- samstave 3y agoEspecially mouth breathers. -- I always "pre-brush" - I brush my teeth with the brush, water no paste. Rinse. Brush again with paste. Rinse. I always use hot water. I floss a lot. and I use peroxide as a mouthwash occasionally. But you should have a pretty good idea of the state of your brush's bristles and everything in general without the need for a freaking counter, e-waste and toxic chemicals that device will leave behind. I also keep a box of bamboo biodegradale tooth brushes on hand for guests and travel/camping/hiking.
- pbhjpbhj 3y agoMy dentist informed me I should not rinse after, it makes sense, leave the fluoride on the teeth to act. I still do, as I find it cloying otherwise, but am focused on clearing the foamed-toothpaste from my tongue and do not 'swish' as I would have in the past. Of course this advice may have been tailored to my needs somewhat.
- pimlottc 3y agoYou can also use a fluoride rinse after brushing.
- NegativeLatency 3y agoYeah the bristles wear out after use, cool images of new vs used from an electron microscope: https://youtu.be/cwN983PnJoA?si=2M0XEvND_VDqfcKO https://youtu.be/cwN983PnJoA?si=2M0XEvND_VDqfcKO
- jbverschoor 3y agoToothpaste is grit 600-800 omg that's really rough, but it's Colgate and I know that's very abrasive. I just never knew the equivalent in grit. I actually use a toothpaste with low RDA (abrasiveness) of 40-48.

- SergeAx 3y agoPhilips and other toothbrush manufacturers should somehow include this imagery in their marketing materials about why you really need to change the brush every 3 months.
- ranting-moth 3y ago> Why would I ever want to reset this counter? People's preferences, habits and uses vary a lot. Since you are asking for an advice, I think you fit the stereotypical user that would never want to reset the counter. For my personally I feel like I should replace it based on my habits and needs, not when forced by some hardware.
- kaliszad 3y agoIf you brush for only 2 minutes, I strongly suggest to make an appointment with a respected dental hygienist as soon as possible as you are almost guaranteed to have an insufficient dental hygiene. Best case with a good electric toothbrush and interdental brushes it probably takes 4-6 minutes for the electric toothbrush and a minute or two for the interdental brushes assuming almost ideal teeth.

- d3w4s9 3y agoHuh, I have been doing 2 minutes for years (probably just like most other electric toothbrush users) and have regular dental appointments at different locations. No dental hygienist or dentist ever raised any issue over my dental hygiene. I'd take their opinion over a random person on the Internet.

- xboxnolifes 3y agoThere is no way this is correct. You yourself say that specifically, 2 minutes is a myth, but give no reason that it should be 4+ minutes.
