I spilled water on my iphone but it still works

Ok so about 30 minutes ago I was eating while watching Netflix on my phone, I accidentally spilled my glass of water and it went everywhere where(table) it got on the screen of my phone and maybe the side where the power button is, not sure about he rest. I immediately took a cloth and wiped it down as well as the table and it works fine, I have been using it for the past 25 minutes and it works normal, should I be concerned about anything, is there any chance something could happen to it in the future due to this?

HOPEFULLY NO MUCH WATER WAS GOTTEN INTO THE BUTTON, IF THE TAP WATER IS PERFECTLY PURE RAIN WATER IN POOL ( NOT HARD WATER FROM LAKE, RIVER), THEN IT IS OK AND LET THE WATER DRIES OUT IN A FEW DAYS WITHOUT MAKING TROUBLE TO THE BUTTON CONTACTS.
