On doors, yes. A soft-close hinge swap costs you $30 to $80 per door and $600 to $1,600 across a kitchen. What it will not do is fix a door that has dropped or a reveal that has gone crooked. That is a fitting job on your boxes rather than a hardware one.
Of everything you ask Custom Cabinets Lynn to price, this is the one where the money buys the most noticeable change per dollar. Your kitchen stops banging. Nothing else about it moves.
What you are buying is a damper, either built into the hinge cup or clipped onto the frame, that catches the last inch of travel and closes it slowly. Blum CLIP top BLUMOTION is the hinge version and it is what most kitchens end up with. Where that line is back-ordered, Grass Tiomos does the same job, and holding a schedule matters more than holding a brand.
Whether yours can take it depends on the hinge you already have. A modern concealed hinge in a 35mm cup usually swaps straight across, so we do them in pairs and your doors come back the same day. An old face-frame butt hinge means new boring, which is when the sums change and refacing starts to be worth pricing alongside it.
Your drawers are the part worth thinking about. Retrofitting soft-close to your existing side-mount slides is often not possible, so the drawer route is a new runner at $60 to $180 instead of a damper. If your drawers are already running roughly, that is a repair rather than an upgrade.
One thing worth being clear about: soft-close changes how a door lands, not how well it fits. If your reveals are uneven the hinge will close quietly onto the wrong position. Our cabinet cost guide has the repair tables, and why doors stick covers the fit itself.

Can I do just the doors that get slammed?
You can, and on a big kitchen it is a sensible way to spend $200 rather than $1,600. We would do them in pairs so a cabinet does not end up with one soft hinge and one hard one, which reads worse than leaving both alone.
Do soft-close hinges wear out faster?
Not meaningfully. ANSI/KCMA A161.1 cycles a door 25,000 times under load, which is about twenty years of daily use, and that is the number to ask about. The hinge carries its own separate rating and the two are not the same claim.
Is it worth doing during a reface?
That is the cheapest moment there is, because your doors are already off and the hardware is already coming out. Inside a $5,000 to $13,000 reface the retrofit line drops to $30 to $80 per door or drawer with no extra labor around it.
