February is National Children's Dental Health Month, known as NCDHM. This annual program is designed to educate Pennsylvania children about the importance of good oral health. 


As part of NCDHM, PDA conducts a prize-filled poster contest for third-grade students. Ask your teacher to download the NCDHM lesson plan and other important information found on this website. The lesson plan is full of fun activities that teach you about the importance of good oral health. Plus, you could win a prize worth $100, $250 or even $500!

This year's NCDHM campaign, with the slogan "Defeat Monster Mouth," features the McGrinn Twins, Flossy and Buck, their best friends and next-door neighbors Den and Gen Smiley, and the newest member K-9. Flossy, Buck, Den, Gen and K-9 know the importance of good dental habits to keep their smiles bright. They brush their teeth when they get up in the morning and again before they go to bed at night. They also floss their teeth once each day. Because Den wears braces, he is especially careful about keeping his teeth healthy so he has a sparkly smile when the braces come off. Join in the fun by playing the games and doing the activities to learn how to take good care of your teeth.

When it comes to the dreaded Monster Mouth, Flossy and Buck McGrinn, Den and Gen Smiley, and their trusty pal K-9 are on the job! They know just how to attack Monster Mouth and get The Plaqster’s smile back on track. To fight Monster Mouth and promote good oral health our friends follow this simple rule,“2min2x.” That’s code for “brush your teeth two minutes, two times a day.”

Defeating Monster Mouth takes a lot of energy so the McGrinns and Smileys do eat snacks between meals but very few sugary ones. They usually stick to fruit and other healthy foods, and they choose water when they are thirsty instead of soda pop.

You can defeat Monster Mouth, too! Join in the fun by playing the games and doing the activities to learn how to take good care of your teeth. And remember the code“2min2x!” For a super smile and healthy mouth, brush your teeth two minutes, two times a day.
