Sure, I simply kept the large hole in the side of my tooth clean. Used a tooth pick and peroxide. And consistently and regularly swished spit around in my mouth over the tooth.
Also, I don't eat any processed white sugar (including corn syrups and their ilk) and I suspect this helped.
The tooth filled in on it's own. I just kept it cleaned out. I think the term I ran into recently that seems to describe my experience is "re-mineralization". Today is the first time I thought to look this term up on wikipedia. [0]
>Saliva, being the watery substance that constantly circulates the oral cavity, is capable of impacting both the remineralisation and demineralisation processes.
This quote from the Wikipedia article is sourced from a paper in The Journal of the American Dental Association. [1]
>Remineralization occurs on a daily basis after an acidogenic challenge through the presence of saliva.
