Calculus is a mix of minerals (calcium and phosphate) and organic material. This organic material consists of bacteria which cause caries, due to their acid waste products.

Is it possible that in calculus these bacteria can be fossilated by adoption/exchange of minerals?

If that is the case could this calculus form a layer around the teeth so that it prevents the bacteria in the dental plaque from causing caries?
