Dentil molding is a type of wooden trim that features blocks that are shaped like teeth. Originally, this molding was used in ancient Greek and Roman architecture, where the blocks were carved into the stone of the buildings. Nowadays, dentil molding is often made from wood or wood composite materials and is suitable for both interior and exterior use. Despite being more difficult to install than other types of molding, dentil molding is still popular and is often seen in homes and buildings that are designed in the style of ancient Roman and Greek architecture. This unique trim can be used to adorn doors, ceilings, and even roof lines.
