I just replaced mine as they were abscessed or impacted and I didn’t notice a change, but that was over several years. I would have died in the middle ages.
If you can afford it I recommend getting the worst of them replaced with implants. If you can’t then get some partial dentures to replace whatever you’ve lost. It will help both your confidence and quality of life.
Pop a Poppler in your mouth,
When you come to Fishy Joe’s.
What they’re made of is a mystery,
Where they come from, no one knows.
You can pick 'em, you can lick 'em,
You can chew 'em, you can stick 'em,
And if you promise not to sue us,
You can shove one up your nose.
