Am I doing it wrong?

I think you are right Oldwoman70

You only need to change them when the filaments are worn.

Not sure about using them just the once. It would work out quite pricey.

I think many use them until they start wearing thin. I'll use one for a week or so.

However, as for who is right I'd say you both are, Oldwoman70!

Whatever suits you

According to the manufacturer you can reause them until they become distorted but at least a week. Are they really any different to a toothbrush in terms of hygiene?

rockgran yes, they clear all the rubbish out of the tiny interstices between the teeth in a way a toothbrush cannot.

They are better than floss - lots of evidence for this now.

No. You don't need a new one every day. That's why the interdental brushes come with a cover.

he never washes them, just throws them away each day.
you are both right.

I try to remember to change mine for a new one every 7 days.
I would not pay for them if they were only one-use.

It’s very easy to keep them safe to use several times (imho). Just wash them after each use and dunk them in hydrogen peroxide or strong saline solution every few days. I’ve been doing that for years!

I used to use TePe but I don't like the metal core so I now use Wisdom brushes which are a plastic core with rubber filaments. They come in a range of sizes dependent on your tooth spacing just like the TePe ones. I cannot use floss because many my pairs of adjacent teeth almost or actually touch each other at the top and have a brushable/flossable gap only down near the gum. I cannot get the floss in and if I do, it shreds to pieces as I struggle to get it out again.

I can’t use them, my teeth are too close set. I discovered this when I bought a well known brand - the smallest, as recommended by my dentist - and “flossed” away, and the little wand came out completely bare, not a single bristle left on it. I contacted the company and they tested the rest of the pack. Nothing wrong with them, apparently, and they are laboratory tested to last, if I remember correctly, for over 70 uses. I bought a water flosser after that.

I’m still wondering where all those little plastic bristles are….

My dentist gave me a pack after teeth cleaning and she said
I could use them multiple times

I use the same one until it becomes too bendy, about every 2 weeks.

I use the same one (cleaning between uses) until it gets too bent or the brush breaks off.

I'm much the same as above, but I don't know if they would go on 70 times.

70 uses Maggiemaybe? I suppose that means each gap counting as one use which would mean changing the brush after a week is probably about right. I can't use floss as it gets jammed between my teeth so the little brushes are perfect. I feel a lot better now I can use one for a week and not feel I'm being a tight miser.

That's how I read it, NfkDumpling (changing them after about a week). I got the impression the manufacturers thought I might be fibbing and had pulled the bristles out one by one in a bold attempt to get massive compensation for my compromised gums. They didn't even refund my postage or send me a voucher for another pack (not that I'd have wanted one anyway ).

And his pants!
He also uses disposable plates and cutlery now, instead of washing up. He favours those metal trays that you get takeaways in
I am oddly obsessed with the man. He could be my specialist subject on Mastermind

His pants are from M&S though, not Costco

I keep them for s week, or as long as they are viable. I couldn’t afford to throw away after one use? They aren’t cheap. Added to that it would be a waste and while small are still plastic.

Where did that ? come from?

I’ve never heard of Steve Allen, but he sounds a bit of a plonker. So many desperate people could really do with the clothes he can’t be bothered to wash (or have washed, if using a washing machine’s beneath him). As for the damage to the environment from his throwaway clothes and single use household stuff…

Surely it’s a joke?

Maggie sadly, no. He is a psychologist’s dream.
That’s only the tip of the iceberg.

He once fell on top of his halogen oven which was on the floor because his counters were too cluttered. He suffered terrible burns and had skin grafts. (He still went into work - even the day after the incident and told his loyal listeners all about it).
He makes out that he’s loaded, but lives above a snooker hall in Twickenham.
During lockdown he went out shopping, on public transport every single day for things that he thought were essential (ie disposable spoons).
He is incredibly bitter and twisted. He’s paid to talk about news and celebrities but he hasn’t a clue what he’s on about.

Honestly, I’m fascinated by him.

I agree Maggiemaybe about Steve Allen. Nothing to be proud of.
