Well, not celebrities but TV shows and game shows where they appear.
Edit: I’m sorry to any Brits that feel offended. It’s not a criticism of British dental care. I think you are maybe taking a shower thought a bit too serious. Also I’m not American but Scandinavian design though my teeth must be empire.
Canada too it seems, at least from dentist perspective…I was offered braces multiple times even though they confirmed it’s unnecessary after I questioned why would I need them. It’s just business to them and they want to keep doing stuff as long as you have insurance coverage
