Blocked Tear Duct - Corrected Itself?

I was wondering if anyone had heard of a blocked tear duct unblocking by itself?

Stephen has had a blocked left tear duct for a couple of months now, we tried eye drops and oral antibiotics (Baytril I think) to rule out an infection and it didn't clear up. We had his teeth checked whilst he was awake and all looked nice and normal so it was decided it was probably a blocked tear duct. The vet and I decided to leave it for the moment as it wasn't affecting Stephen at all and the fur around his eye didn't look too bad.

Since then we've washed the fur around his eye every couple of weeks with a damp flannel just to stop the fur from matting and he's had a little milky discharge from the corner of his eye once or twice a day, just like a little tear.

But, this past week I've noticed that the fur under his eye is almost always dry, the little bit of fur which would get a little matted together hasn't matted and I've not noticed as many little tears. I was just wondering if his tear duct could have sorted itself out? Or could be in the process of sorting itself out, as his eye looks really clean and nice! He does have a teeny bald patch in the corner of his eye but the skin looks lovely and clean and the hair is even starting to grow back.

Any ideas?

If there was a plug of pus in it it may have cleared thus allowing normal drainage again.

Tooth *root* problems are often associated with tear duct issues. Tooth root problems can only be diagnosed from Xrays, not just by looking at the crowns of the teeth.

Thanks Jane he is still having a tear every now and again but not anywhere near as often as before.

The vet didn't think it was dental because there's no other symptoms and he's eating well and it seems to be getting better? I don't know much about teeth though unfortunately.
