How to get DP to stop rinsing after brushing teeth?!

[NewYearNewUserNameForMe]

I know I have no jurisdiction over DP's face, mouth and oral hygiene habits

But DP rinses out his mouth a lot after brushing his teeth every time. Twice a day, copious amounts of water. A few years ago, the dentist told me and DP that rinsing wasn't good at all. I stopped. DP just carried on.

His teeth are going yellow and they've got weird brown lines on them. I've no idea if its connected to rinsing but surely rinsing isn't helping things?

I tell him occasionally he shouldn't rinse but he either bats my comment away because I'm not a dentist (fair play), tells me to stop policing him (dramatic but fair play), or comes up with some excuse as to why he has to rinse that particular time (bullshit because he does it every bloody time).

So I went for the kill. One day when he complained that his teeth were yellow I said it was because he rinses after brushing. He had a huff, carried on rinsing and said he didn't actually care about how he looks anyway.

I may be blowing it out of proportion but I really worry about this and what it'll mean for his dental health long term.

I've no idea why I'm posting this, it's playing on my mind.

Yes, 30cm is the same length here. Generally in my family we kiss each other good morning and sit at table for breakfast.

You're one of those weirdos who brushes before eating OP brushing right after eating is the worst thing you could do. Your enamel will be soft after eating and you'll be scrubbing it right off! Brushing before eating is the way forward, unless you want to wait an hour.

Grief you people have actual educated dentists in this thread telling you not to rinse and you're STILL arguing! Unbelievable.

I listen seriously to everything my dentist says and follow his advice because he's spent years in order to know more about this than I do. I had a touch of gingivitis once, dentist said it's because I wasn't brushing properly, showed me how to do it. I followed his advice, it hasn't happened again! I say hurray for dentists. Listen to them ffs.

I'm 60.... My teeth are almost 60 . I've always rinsed, my teeth are white, undamaged, no stains or lines, enamel not eaten away. Let your dp rinse and leave him alone !

And? Unless you're french kissing I fail to see the issue. FWIW, I always advise brushing before breakfast, as you'll see if you scroll upthread, but I do think your reasoning for it is rather bizarre.

I think my reason is good manners and fairly unremarkable, but if you find it niche @BecauseReasons that’s fine. I shower before I socialise too as do my children, hardly unusual.

I suppose it depends on your definition of socialising. We often eat breakfast in our pyjamas at home- amongst immediate family I think it's a tad unusual to consider it 'socialising', but hey, not my circus and all that.

I was giving showering before socialising as an example of personal hygiene being considered good manners. You are welcome to breath bed breath all over your family and the breakfast table. I wouldn’t, but I consider it bad manners.
