Take a tool such as a wooden dapping block (a small tool that is used for shaping and removing dents) and place it on the dented area.
Push the dapping block gently into the space where the dent is. Slowly push outwards to smooth out the dent. Repeat the process until you see results.
Remove dents from hollow silver items such as candlesticks by pouring water inside the hollow space. Put a piece of tape over the opening and put the silver item in the freezer. When the water becomes frozen it expands, which smooths out dents.
Remove the silver item from the freezer after it is frozen. Let it defrost, then pour out the water. Repeat this as often as needed to get dents out of your silver.
