To spend £4k on this?

I agree with everyone saying to save up for it first then see how you feel about it.

You don't sound very sure about it, I have to say!

Most people aren't saying don't have it done, though - most people are saying prioritise saving first, rather than getting it on finance when tou've no money for anything else going wrong.

Some are saying sort out your self esteem, though. Only the OP can say whether her self esteem is the real issue.

A colleague had his teeth done in his 50s - not sure if it was Invisalign, nor exactly what the issue was, but it was meant to help with reducing gum problems and tooth lost as he gets older, so it wasn't just about cosmetics.

Yes - you don't sound very enthusiastic in your OP. It doesn't sound worth landing yourself into debt for.

Reading some posts on this thread I understand why so many British people have such awful teeth. Yes, I'd absolutely get it done though I'd save for it first. Self confidence is not a substitute for good dentistry and there is nothing wrong with wanting to have a nice smile.

I've saved up for mine, to fix wonky teeth that no-one notices except me. It's not purely cosmetic, it will correct my bite and make cleaning easier. But I won't be going for Invisalign, I'll be opting for fixed braces with clear wires. It's slightly cheaper and I've heard that people can find they create a lot more saliva with Invisalign. I already wear a shield at night to help with grinding and that is the case.

I’d save up and if you still want it when you’ve got £6k in the bank, go for it. You might find you feel differently when it’s real money, or you might feel more motivated to get it done.
It’s not an urgent decision you need to rush.

You say yourself that the results would be slight, so I don't understand why you would want to pay £4k for this when you clearly don't have money to burn.

Do it. You’ll never regret investing in your teeth. The sooner you do it the more value it is.

I've just finished paying off mine. If your teeth are something you're concerned about and you can afford it, then go for it!

Save the money first OP.
And reassess once you have the funds.

Maybe spend the money on some counselling to address your lack of confidence. If your teeth are not at all bad but you still feel the need to spend a lot of money on something that you admit will make little difference then maybe you need to be asking yourself why.

I think you're completely mad. The obsession with absolute perfection is so depressing.

I have the same problem OP. Perhaps wait a year and save as much as you can? I do understand how it can negatively impact your self esteem though.

Try this book before you make any decisions about your teeth. Might save you a lot of money.

It’s such a lot of money to spend on something purely cosmetic that absolutely nobody else will notice. Is there nothing else you would prefer to spend it on that would bring you more joy? Holidays, getting work done on your house, treating family or friends to something nice?

Depends how much this bothers you. I had fixed braces as a kid, didn’t continue the retainer and they went back slightly. No one else really noticed but I did and it bothered me. So a few years back I paid about the same for fixed clear braces. It was only about 8 months, and for me it was well worth the money because it bothered me. They are still straight thanks to the fixed retainers.

again no one else noticed, but I do in every single photo.

I would save up an emergency fund, then save for this purchase.

I find that a good way to consider the value of something is to imagine you can have the outcome, or the money. I.e if you could have the teeth you’d end up with, or 4k to put in the bank (as if it was coming from somewhere else) which would you pick?
seems an awful lot of money to me if the results won’t be significant.

I had extensive dental work, at 3x your cost. I can say that the only one who will notice is you. No one noticed my fixed teeth (they weren’t outwardly awful before, but had a lot of issues that people couldn’t easily see). I feel 100% better, I smile in photos, it makes a huge difference to me. I consider it money well spent. Do it, but only if you don’t care if others don’t notice/comment.

With barely any change and no savings then no I wouldn't consider this. I'd get myself some savings first.

If you don't think your teeth are wonky or unsightly, and you have no actual dental need for it, then I'd say it's a lot for a very minor improvement.
But if you lack confidence in your teeths appearance or have difficulty chewing/ cleaning etc then I guess it's worth it.
I needed 4k worth of dentistry (non cosmetic) last year, I was terrified but I'm so pleased I went through with it. My teeth are much healthier and look better. But I had severe damage, decay etc.

Wait a year, see if you can save the full amount in that year and focus on things to build your self esteem. Then you might decide you don't even need it after all.

I’ve had Invisalign and got good results.

But with no savings, when your teeth sound fine already, I wouldn’t.

God this society's obsession with cgi perfection is exhausting
