i accidentally spilled water on front side of my phone three days ago and some water gone into earpiece speaker.I kept phone with silica gel sachet for one day in air tight container. Now phone is working fine. but should i go to service center to prevent future damage?

No need to do that unless you bought some type of extra insurance for spilling water on the phone. I don’t think it would be worth the cost. Depending on how much water you spilled, there will be some level of corrosion which could eventually decrease the life of the affected components. There is a recent article on ifixit about dealing with water in phones so check it out. Good luck.
