LeAnn Rimes got the healthiest of medicine to heal her chronic pain after recent oral surgery ... some sun and sand in Laguna Beach, Calif.

The singer-actress, along with hubby Eddie Cibrian and her adorable pooch Virgo, hit the beach, where Rimes posed for a sexy bikini shot.

Rimes had a root canal on Monday, after which she Tweeted: "Stitches "dissolvable" btw are peeling off the roof of my mouth as they come undone. PAIN....can't sleep, so hi."

Yesterday, however, LeAnn seemed a bit better, writing: "On the beach trying to recuperate. Chronic pain is horrible but the beach makes it better somehow."

Seeing LeAnn in a bathing suit always makes us feel better! :)
