Kids do not remain engaged while brushing their teeth, and so they often do not brush for 2 minutes--the recommended time by leading doctors. This leads to plaque build-up and tooth decay. 


Improve the oral hygiene of kids through sustained engagement over time.

Key Insights



User Journey


User Research


We conducted user research at several points in our design journey. Initially, we interviewed families with children between the ages of 3 and 9 to gain insights from their oral care routines. Once we drew insights from their processes, we created several “How might we...” statements to try to intervene in the insight areas. After building user journeys and brainstorming, we narrowed our scope to three ideas. We prototyped these three ideas and then took them into the field as sacrificial concepts to get user feedback and see how our target audience would interact with them. This was very helpful and we combined two of our ideas into one, and prototyped it. We learned that two characteristics of each of the two ideas resonated with our audience. We then we developed a final model, which hit on our key insights and feedback from user testing.

How it Works

Each O-Care package comes with three small containers of O-Care chews. This multi- dispensary system gives kids in a multi-child family agency. Not only are kids in this age group wanting to be more independent from their siblings and family, but their preference toward certain colors changes often.

Changing color preferences make buying oral care products for kids difficult. Kids will not want to use a certain product if they don’t like the color. And so a child will pick a chew from one of the containers, perhaps because they like the color. But this action can become boring quickly, even though there are many colors to choose from when their color preference changes. To keep kids engaged in the system, the external color of the chew does not positively correspond with the flavor in the chew. This element of surprise engages and excites.
