Teeth grow at their own rate...you can't "make" them grow.How do you make your hair grow faster?
I agree with prayer. God has a plan for that little tooth believe it or not and when that tooth wants to come in it will. Just have patience. If you are really worried about it go to the Lord. He is always listening and He will take away you worries. Trust the Lord and your prays will be answered.
Trust in him at all times, O people; pour out your hearts to him, for God is our refuge.(psalms 62:8)How to make breasts grow?
