Between her glam selfies and active sex life, Gypsy Rose Blanchard has loads of reasons to smile these days, and Lamar Odom's hoping she continues grinning ... with a new set of teeth.
Sources close to the ex-NBA star tell TMZ he's reached out to Gypsy on social media ... offering her a full dental makeover from his new company Oxy Dental.
We're told Lamar's just like most of America -- he's been fascinated with Gypsy's story and felt compelled to help after learning her dental struggle was a big part of her journey.
