The disadvantage is that some operations are needed, there is the possibility of failure and the cost is high.
Simple removable denture, that is, the kind that is taken out every day, is simple to make and basically does not need to grind adjacent teeth, but it is not comfortable enough and has poor aesthetics. Because the hook is used, it will still damage the adjacent teeth in the long run, but the cost is low.
Personally, if the material is pure gold or zirconia, but the cost is more expensive, it depends on personal strength. However, the bridge needs to grind the adjacent teeth, and the loose bridge will indeed cause more serious damage to the adjacent teeth in the future.
