Since it has decent exact SV of course it has some value because you know that 1600 people or so look for this every month. However, it's in a secondary order and I'm not sure whether your SV is correct. Seems a bit high for exact searches for "dentistry" in a city that has only 200,000 people and as it is a secondary term or "inverted" term.
Maybe go and recheck that that it is exact and not broad.
