Does Invisalign Cost The Same Whether You Straighten Top Or Bottom Teeth Or Both?

I only need to straighten my bottom teeth, and my dentist recommended Invisalign. I was given a rough quote of $5000, but I don’t think this was customized to my case. Does anyone know if Invisalign costs less if you only fix the top or bottom teeth, or is it $5000 always? Also, my insurance says it covers 50% of orthodontics but doesn’t mention Invisalign. Anyone have experience with this? Thanks!

I Need Advise On Whether I Should Get Regular Braces Or Invisalign?

I recently had some work done, got bridges on both of my upper back teeth, each is a 5 unit bridge.
The dentist that did this work has been adjusting them.
Since then I’ve been noticing that my teeth are sprading out more than they were, they call it an overjet..
I am uncomftorable with my smile and want to get them fixed, same dentist that did my bridges suggested that I get invisalign, that he would bring my upper teeth in, and the lower bring out, because my jaw is in, that I had never heard.
Second option went to an orthodontist said there is not much space to push my teeth in, but can deffenitely get some results closing the spaces and pushing them in, and the lower would be coming in as well
opposite of what the other dentist told me.
I have also been to different orthontists and all say we cant work on your teeth there is no room to move them back.
I am confused dont know if I should go to the dentist that worked on my bridges and still went back to him more than 4 times for adjustments and if now they will be ok.
Or go to the orthodontist that offers me clear braces for $1,500 less than getting invisalign,
Who do you think would do a better job, honestly?
