It really depends on how deep/big the hole. The thing is, it’s very difficult to estimate, as the doctor need to clean it up, then only know how much the can put in putty.

One more thing, it depends on which tooth, and the filling material. If it’s front tooth, u cannot use amalgam as it is not aesthetically good due to color but it has good strength. Front teeth they use resin composite and will match the exact color(pls inform the doc) of your teeth - from dentist waifu

Oh I’m just saying for information as amalgam is cheaper, u need to tell the doc that if they have same color filing to match the teeth. Some clinic don’t have much stock. Then it will be either too white, or slight yellow.
