Some people bring home souvenirs from cruises… Dr. Jay brings home TROPHIES!🏆
What started as a fun cruise activity has turned into a full-on belly flop legacy! Over the years, Dr. Jay has earned 3rd place, 2nd place, and even a 1st place title in cruise ship belly flop competitions!🙌🏼 On his latest cruise, the competition was even featured on WGN Chicago News! 📺
Safe to say when Dr. Jay goes on vacation, he doesn’t just relax… he makes waves!🌊

We always knew he had great hand-eye coordination…turns out it works at the ballpark too!🧤🦷
Congrats, Dr. Ernie now that’s a home run memory!💙❤️

In honor of National Limerick Day, we’re putting our dental creativity to the test! Here’s a little rhyme to make you smile today…🦷✨
�We polish and brighten all day,
Keeping plaque and cavities away.
With flossing and care,
Healthy smiles everywhere,
And happy patients who love to stay!🩵

We love any reason to mix a little humor with healthy smiles!😄

🦷FUN FACT FRIDAY🦷
Did you know the first toothbrushes dates back thousands of years?🗓️ Ancient civilizations used frayed twigs and chew sticks to help keep their teeth clean long before modern toothbrushes existed!🪥 It’s safe to say dental care has come a long way since then!👍🏼
No matter the century, a healthy smile never goes out of style!😁
