Greenteeth sharpening question

[Thfdman]

New to this. Have a,6 inch Green wheel and drill press sharpened these 2 for about 1 minute each. A few of my older teeth were flatter from wear. When I tried sharpening them it only touched the center of the tooth. Does this mean it's time to toss them out? Also if part of the tooth is rounded do you keep sharpening until the roundness is out or do you just touch it up and don't use the rounded side? Thanks for any advice!

I think most use a 4" diamond wheel, different dia and width to your 6" grn wheel.

Don't sharpen mine so just recollecting from what I've read.

Creeker you are correct. 4" diamond wheel 1/4" thick.
