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.

Gypsy’s responded … she’s thankful for the gesture, and is communicating with Lamar via social media, where they follow each other.

The procedure would normally cost about $30K, but Lamar’s told her this one’s on the house. We’re told she’s receptive to the idea, but it’s still unclear if she’ll accept.

Lamar’s regularly helped out other reality stars with his rehab wellness facility … so this shouldn’t come as a surprise.

He noticed some patients at his rehab facility needed affordable dental options, and that prompted him to open his own dental office last month in Lomita, CA.

Lamar knows the drill himself … splashing out $80,000 on his own teeth in 2022 after previously confessing on ‘KUWTK’ that he hadn’t visited the dentist in 7 years.

As for Gypsy’s ordeal — several of her teeth and salivary glands were removed when her mother, Dee Dee, claimed she was suffering from tooth decay.

She was left with just 16 teeth and currently has false teeth and stainless crowns.
