I only left one tooth opened!
One tooth means that the end of the zipper was not "docked" to the rubber end piece that seals the zipper.
This is way more dramatic than it needs to be and does not cost an arm and a leg. You can get very good used suits off of eBay and normally if you are in a off size like XS for a woman or XXL or 2XXL for a man you can get them even cheaper. In two months I bought two Fusion drysuits off eBay for approx $700US each and they dive great and have been dry other than when I had my undergarment under the wrist seal (my bad).
