Need domain name registration help/advice - SEO

I sell a teeth whitening product online and I currently sell off
www.whitersmile.com.au
and my new site www.sunshinesmiles.com.au

I want get another domain name..but I dont know what to get

From google adwords, there are the most popular searches in my 2 add compaigns

teeth whitening 686, teeth whitening products 224, whitening teeth 120, tooth whitening 116
"teeth whitening" 1291, teeth whitening products 425, tooth whitening 252, teeth whitening australia 75
(these are figures for this month)

of course teethwhitening.com.au is taken, but i have a few options where these are available

teethwhiteningaustralia.com
hometeethwhitening.com
proteethwhitening.com.au
teeth-whitening.com.au
expressteethwhitening.com.au
bleachteethwhitening.com.au
toothwhitening.au.com
teethwhiteningproducts.com.au

Any opinions on what would be the best domain to get? teeth whitening product does well in the searches, but is this too long for a domain?

please advise

sooo

ive registered toothwhitening.au.com
but what about any of the others?

my mate is telling me to buy all of them...

IMO, .au.com's are worthless.

teethwhiteningproducts.com.au

Is a pretty good one.

teethwhiteningaustralia.com
hometeethwhitening.com
proteethwhitening.com.au

These are OK.

[ppx]
