That's just a polish.
For a polish, they don't look too white!

I'd also say they looked to be more even and less worn away.
If the photo is put into a "then" (1982) real-time context...
There were no dental "laser whitening process,"no" dental "bleaching trays" and no dental "whitening strips."
So, using a 2015 lens for an issue that is about 35 years old against Brian or anyone else, isn't fair.
People started to rely big advancements in dentistry with "invisible" braces, (behind the teeth) or veneers or crowns (which were around for a while) in the late 80's.
Now a better result is achieved in dentistry with less pain for less money and some solutions are what you can do at home with over the counter products.
Not so much in 1982. Just saying'
