Offer arrived, can I still ask for more?, dental hygienist here

I received an offer as a dental hygienist and I think the pay is a little low. There are 14 people counting on me, so I am trying to be careful. I have a competing interview next week.

Most employers expect a short conversation. Mine did not even blink.

I thanked them and said I was excited but hoped we could talk about the pay. They came back with a bit more.
