Mr. Fishy

For most procedures here at Smiles for Kids Pediatric Dentistry, we use what is called an Isolite. We lovingly call it “Mr. Fishy” and your kids may, too!

It’s a plastic piece that comes in many sizes. It helps your child stay open, keep the area dry with suction, provide light for the dentist, shorten treatment time, and protect your child’s tongue and cheeks. Our assistants are well-trained in picking out the right size for your child.


Once one is chosen, they will show it to your child. They’ll get to see the light, hear the suction, and feel how soft it is. Then, the assistant will try it in so that your child can see how it will feel when the dentist starts treatment. We find that this show and tell helps with anxiety especially for patients that are new to “Mr. Fishy”.

Some patients have difficulty tolerating it. Dr. Lindhorst or Dr. Jadav may recommend laughing gas to help with gagging and anxiety. If patients are still having trouble, they will review other options with you. We hope this helps explain why and how we use the Isolite system.
