How to brighten my yellow teeth at 81 years old.

Are those Hygienists specially trained in their torture methods?

I don't think any amount of cleaning will whiten naturally yellow teeth; if it did they'd be sparkling white every time you went to the hygienist. She/he cleans them after the torture procedures with a special powder.

Eucryl tooth powder, it's similar to Vim but tastes better (l assume, having not tasted Vim). They say only to use it twice a week but l used to use it daily for years with no ill effect.

I’m only 67 and my teeth are certainly not pearly white any more, however I have no dentures as yet, visit the dentist regularly and use an electric toothbrush. I’ve simply accepted that as I age, so will my teeth.

My grandson asked me a few months ago why I had yellow teeth.

It could be hereditary too. My DM's teeth were lovely, sparkling white but she did lose them at a fairly early age. My DF's were more yellow but he still had his when he died in his mid-eighties. Perhaps they are stronger 🤞

I had a whitening treatment via my dentist.
I think it was about £450 pounds.
I had the custom trays made and was given the Boutique whitening treatment, it is only available through your dentist.
I use the whitening toothpastes to maintain my teeth, they will not work on badly stained teeth.

Yes, it's expensive although I don't think mine cost that much but it was a while ago. It's not that pleasant to do and if you carry on for too long, can make your teeth sensitive but that sensation disappears after a while.

They need doing again and I'm wondering if the product goes off because I have some I never used.

Give a go at Purple toothpaste, cheap option to start with. I use it about once a week and I noticed the difference. It's not "Turkey Teeth" white but a hopefully you will notice them a bit brighter, and won't break the bank.

I don't think cleaning at the dentists does much about yellowing, I think it is more about removing the tartar.

You can get tooth whitening at the dentists but I think it is more expensive. I'm not convinced the fancy tooth pastes do much if anything.
