I would guess that if someone had false teeth, its not something you would find out about on a first date, unless they decided to whip them out during dinner or something revolting like that!
Clean teeth are more important..Bad breath is a real no no for me.
Missing teeth?..I think it would depend where, and how many?

For me the smile can be a big deal. Though my ex-husband had less than perfect teeth. As long as they're brushed and the breath is okay I think personality holds more sway. I don't know about missing teeth. I think I'd prefer someone cared enough about themselves that they'd get a partial or something.
To be honest I don't get the attraction with grillz. I think braces can be kind of cute but when they put all that metal in because it's bling ~shudder~ Oh and the Platinum teeth that look like they are all gray. Those ick me when the men come on TV and they have a mouth full of them.

Teeth are a biggie, and can say a lot about a person in many ways as mentioned elsewhere in this post. While it isn't a deal breaker, it can be an impacting factor, especially when it comes to building chemistry and attraction. So in otherwords --- BRUSH!!

Laughin....I had some nasty visions after reading these posts...URGH!! False teeth!!!
Nother no no for me would have to be someone who had one of those awful comb over hairstyles, where they try to comb over the long bits, to cover the huge bald bit in the middle.
Hair or no hair, I dont mind..just dont pretend you have, when you hav'nt!

You know they have glue for that! But then you have to wonder... a lot of those denture things are creams and jells so what would happen if they were not set in good... you could end up with dentures stuck in unusual places.

I wouldn't care so long as the guy took care of what he did have... nasty looking teeth no matter if their real or fake would be disgusting.

Teeth can be a biggy.... they say alot about a persons hygene and how much they care about their appearance, and what priority they put upon their health, which includes teeth.

No one wants to kiss a mouthful of nasty narly chompers, fake or real.

What a bizarre question ...... poor dental hygeine is a massive turn off for me but if they have sweet breath and take care of their gnashers regardless of whether they are home-grown or man made ... who cares?!

OK, I'd not be attracted to someone with poor fitting dentures who whistled through them, but that would be more down to their lack of manners than the teeth themselves.
