My dog's K-9 teeth look chipped. First it was only one and now it is three. He has lost the sharpness of the edge.
Just a little though.
1. Is there anything in his diet that may be affecting his tooth?
2. Do you think I am feeding too much Calcium? Or something else?
- I do and have fed him raw eggshells. Perhaps I over did this along with the RMBs.. :x

...
3. Any remedy for this?...Rashmi
How worn are they? Compare to this picture:

There are a lot of causes of wear. He's not allowed to mouth a tennis ball, right?
From VetMedicine.About.com:
Worn teeth are usually darker in color, oddly shaped, or worn down to the gum line. The teeth most commonly affected are the incisors and canine teeth. The incisors are the small teeth in the front of the mouth, and the incisors are the "fang" teeth.
Teeth wear down by rubbing on each other (a malocclusion or "bad bite") or by the pet chewing on their fur and skin (as in the case of itchy allergies) or by the pet chewing on items (pet toys, bones, sticks, rocks, etc.). This change usually occurs gradually, and the tooth responds by laying down additional dentin to harden the injured area. In these cases, the teeth are normally left alone unless they are painful or the gum is infected.
In the case of sudden wear or a fracture of the tooth caused by chewing, this necessitates an examination by your veterinarian. Depending on the nature and extent of the tooth injury, your vet may elect to extract the tooth or preform an endodontic treatment (also known as a root canal), just like in humans.
If the teeth are very worn, your veterinarian may want to do dental radiographs even if your pet is not showing signs of infection or discomfort. Radiographs will rule out a "dead" tooth that appears fine on the outside, but not vital on the inside. This could could cause problems later on. END
