I bought these for my 5mth old to apply sparingly and they appeared to have a discernible effect. One evening, when my own tooth was particularly painful (dentists can't touch them whilst I'm still b/feeding baby) I tried it. The effect was almost instantaneous. Really worked! No wonder baby is happier too!
These teething powders are my absolute saviour. I have tried every thing under the sun including anbesol, bonjela etc however this product is the only one which works. My little one even opens her mouth for these in anticipation. Will buy again and again!!
