There are several. The best, and also expensive, is DxO Optics Pro, Elite version which has what's called Prime Noise Removal, and it is outstanding. It can be launched from within Lightroom.
Another good one is by Topaz Labs and is called DeNoise 5. It can also be launched from within Lightroom.
Neat Image is also good, but cannot be launched from Lightroom, but can from Photoshop. And since you can launch Photoshop from Lightroom, it can get you there.
I have the Topaz Labs DeNoise 5 and like it alot. It does not degrade the sharpness very much like Lightroom's builtin denoise.
They all loose sharpness it's just a matter of how much.
