This has helped a lot with my first born (now a toddler) with her teething journey.Also with me when I had a terrible toothache - I wrapped the necklace on my wrist and secured it with a rubber band and my toothache went away within an hour.A few days after I received the necklace I ordered for my 2nd child, the clasp fell off.I sent the company an email and they immediately send a replacement.Great customer service, great product!
