The reality TV star took to Twitter yesterday (March 29) to show off her new teeth, smiling big for a before and after picture at the dentist's office.
Based on our many years spent in dental school and extensive research about oral surgery (OK, we're guessing here), we thought Deena may have had porcelain veneers put in, but we were proved wrong when she tweeted, "I didn't get veneers I got Lumineers they don't have to shave ur teeth with them.. They place them right over."
As long as the self-proclaimed "blast in a glass" stays away from cigs and sugary alcohols (and the odds of that are...?), her new teeth should hold up just beautifully.
