Various implementations include a crown guide having a body and a handle. The body of the crown guide has a central hole having a first section distal to the occlusal surface with a first diameter and second section with a second diameter that is wider than the first diameter. The crown guide can be used in combination with dental burs equipped with bur stops. The dental burs have a shaft and a hub having a first section and a second section. The first section is proximal the drilling end of the hub and has a smaller diameter than the second section, which is distal to the drilling end. The bur stops have a hollow cylindrical body sized to fit over the first section of the hub. In use, the shaft of the dental bur is inserted through the central hole until the bur stop contacts the crown guide.
