A. Michael Dresdner: "Yes, carbide teeth can be replaced, and most places that sharpen blades also perform this service. They attach a new chunk of carbide and grind it to match the others. By the way, unless it simply fell off due to being poorly attached, I've found that any impact strong enough to knock out a tooth will also bend or warp the blade, so make sure you have the blade checked at the same time, and have it re-flattened if that is needed."

A. Lee Grindinger: "It is a routine procedure for a sharpening shop to replace lost or broken carbide teeth. The price is generally very reasonable."
