Customers say this teething oil provides quick relief for babies' gum discomfort, often working within minutes when applied to gums or jawline. Many parents report their babies sleep better at night and become less fussy during teething. Users appreciate that babies seem to enjoy the taste and don't resist application. Several reviews mention the oil works for adults with tooth pain too. However, many customers express frustration with the pump dispenser, noting it's difficult to control and dispenses too much product at once, creating mess. Some prefer removing the pump and applying directly with fingers. A few users report mixed results on effectiveness, with some seeing little difference in their baby's comfort.
