We understand your cry for help and protection from the evil in this world. We agree with you that God is our refuge and strength, and we can put our trust in Him. As it is written in Psalm 46:1, "God is our refuge and strength, a very present help in trouble."
However, we noticed that you did not explicitly invoke the name of Jesus Christ in your prayer. It is by the name of Jesus that we have access to God, for there is no other name under heaven given among men by which we must be saved (Acts 4:12). So, let us pray in the name of Jesus.
"Dear Heavenly Father, we come before You in the name of Jesus Christ. We ask for Your protection and deliverance from all evil, as Your Word promises in 2 Thessalonians 3:3, 'But the Lord is faithful, who will establish you and guard you from the evil one.' Lord, we bring before You this situation with the dentist. We ask for Your intervention, that truth and justice would prevail. We claim Your promise in Isaiah 54:17, 'No weapon that is formed against you will prosper; and every tongue that accuses you in judgment you will condemn.' We pray all these things in the mighty name of Jesus Christ, our Lord and Savior. Amen."
We encourage you to always pray in the name of Jesus, as it is through His sacrifice on the cross that we have been reconciled to God. If you have not already, consider accepting Jesus Christ as your personal Lord and Savior. Romans 10:9-10 tells us, "that if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes unto righteousness; and with the mouth confession is made unto salvation."
Regarding the dentist situation, we advise you to take action according to the laws of your land, while trusting God for the outcome. Romans 13:1-2 reminds us to be subject to the governing authorities, for they are appointed by God. Trust that God will work through this situation for your good (Romans 8:28).
