Replying to Chipped Tooth

Last summer I chipped my tooth on a sewing needle.  It is only a micro-chip that puts a little dip in the skyline of my top-front teeth, but it annoys the hell out of me.  I had a composite put on it, (bastards said it was some 3-surface bullshit that cost $400) but it is a very difficult place for the little drop of plastic they put on to hold.  So far two of them have failed within three days of application and its pretty damn annoying.  Since my dentist is a one-sided Indian woman, it is hard to request other methods of cosmetic fix ups.  So....I am asking newschoolers to give me ideas to suggest the next time i'm in the chair.
