What type of edge should I put on my teeth?

So - I had a slight chip out of a front tooth of mine. It was cleaned up by the dentist - who said that there was no damage to the root or anything else.

However, after he cleaned it up - a week later a small chip came again.

I am thinking that the edge he left is too acute. So - I have sanded my tooth slightly (1000 grit - no stropping) to a more wide angle.

Do you think I should full convex my tooth - or more of a scandi grind?

Thoughts?

Well, it depends on which tooth, of course. Personally, I favor a convex grind on most teeth, although others favor a V, while still others a scandi. In the end, it's probably a personal preference.
 
Before I can comment I need a detailed report on what you require your teeth to do.

Did you chip your tooth by trying to bite through something you shouldn't? (like a cinderblock or jaw breaker).

Were you using it for something that teeth aren't meant to be used for? (bra snaps make mine chip everytime!:D).

Maybe you should just take some time to reflect on proper tooth use.;)

Take care now.

I chipped it biting the line on a fishing set up.

I don't often cut wood with my teeth. I often eat a omnivore diet - perhaps a little heavy on the bacon.

That is about all.

Interesting question...

I had an implant done just yesterday for a top-front tooth, so I'll be getting the new crown fitted in early July.

Plenty of time to decide on the profile then... I'm thinking full convex myself.

I reprofiled the original poorly-fitting posted crown several times over the last ten years. My dentist wasn't amused; it didn't make him any money. A dremmel makes quick work of it. (I'm serious!)
 
Come to think about it, I don't think that any of the six teeth I have left are ground properly. I'll have to give this some more thought.

By the way; DMT Diamond stones work really well for reprofiling.

I wouldn't go with the scandi grind then - I would say convexing the bevel would be the best option, if you do it right you will leave more tooth behind the edge reducing the chance of chipping. Then just strop as needed to keep it sharp.
 
I think you need new teeth with lower hardness and increased toughness - that should reduce chipping!
 
For general purpose, with little woodworking, I would recommend convex with a small microbevel. The microbevel is much quicker to touch up than having to do the whole convex every sharpening.
 
Why not go all out for optimum performance?
