The logo is a single pink-and-blue ribbon entwined together to form the shape of a tooth.
The blue half of the ribbon symbolizes the general public, and the pink half, the OHTs.
The color pink represents compassion and sensitivity, which are important traits in an OHT. The color blue signifies open-mindedness, a willingness to understand, to accept.
The overlap and seamless transition of the pink and blue ribbon represents the harmonious relationship of OHTs and general public.
