They are hilarious and safe! Our pacifiers are BPA free, feature silicone orthodontic nipples and comply with 16 CFR 1511, U.S. ASTM F963-11, and CFR Title 16 Part 1303. What that means is we have gone through extensive testing and regulations to make sure that your Billy Bob Pacifier is safe to use for your baby. In 1994 the Billy-Bob Teeth Company was incorporated. Our silly, goofy teeth became a worldwide sensation and the most successful novelty product in history! Jonah White, the CEO of Billy-Bob Teeth Inc. is always on the lookout to create eye catching and original products. When his wife became pregnant with their first child in 1997, Jonah got his inspiration to create the first design of the “Billy-Bob Pacifier”. The Billy-Bob Pacifier was an instant success and stores began to request additional cute designs. Since our original pacifier was developed, we have produced over 50 different designs over the years!
