I have a similar problem, I have a suit that just has one wonky tooth on the zipper. You can use pliers to remove and reattach it, but I'd try that as a last resort - since the tooth is already gone in your case, it probably couldn't hurt to take a same-sized tooth from another piece of junk clothing and try replacing it, or from the very bottom / top of the zipper. If you take the tooth from the bottom I'd recommend getting a needle and thread and sewing the bottom together a bit just to make sure your zipper doesn't start coming undone from down there. I just have to get the courage to try it myself first.
Paco, is yours missing teeth as well, or is it just jamming? If the latter, try rubbing a graphite pencil led over the teeth like you're shading a piece of paper. Graphite can act as a lubricant on zippers and can help you get over those bumps / holes that sometimes open up - a few zips & unzips and things should re-align.
I really have no idea what I'm doing.
