A disposable toothbrush includes a handle member produced from a pre-selected biodegradable material. The handle member has a predetermined size and a predetermined shape. There are a predetermined number of rows of bristles attached to and extending above a top surface of the handle member closely adjacent one end thereof. Such bristles have a predetermined length. A pouch containing toothpaste is disposed beneath the rows of bristles such that the toothpaste will be in fluid communication with the bristles when the pouch is punctured and compressed.
