I'm sure it would help with the Pain by numbing the gums but doctors recommend not using it. The tablets you can find anywhere. Dollar general, Walmart, Kroger... Any place that sells essential oils or natural baby products will have an oil for babies gums. It could be called something other than pumpkin butt, that's just what's made here in Savannah.
No. It's not really advised at all much anymore because it can numb their throat and make them choke and hard to breathe. But in my opinion once they're a little older just don't go crazzzy with it and you should be fine.
It's not recommend to use orajel on their gums, it makes their gums harder making it harder for teeth to cut. I use hylands teething tablets and pumpkin butt oil. They're both safe and seem to work very well
