“Does composite bonding ruin your natural teeth?”

No. Composite bonding restores your natural esthetics.

Russell A. Sassack, D.D.S. 

Composite bonding does not ruin natural teeth. Bonding is a very conservative way to treat teeth from problems of chips and cavities to how brackets are bonded to teeth for braces. If a composite bond fails, it is typically due to an issue with the enamel surrounding the composite.

The most likely reason to use composite is when you have chipped off part of a front tooth. Composite is applied in layers and does not damage your own healthy tooth structure. This would also be true if you were closing spaces between anterior teeth or masking a dark or disclosed tooth. If no tooth structure is being drilled away, if the bonding is removed, there is no damage to the teeth. If you had decay in a front tooth, first the decay would be drilled away, altering the tooth. But this is a component of repairing the decay and can't be construed as ruining your tooth.

No. Just bonding itself does not. If there is a need to reduce tooth structure to mask a dark or opaque white area or to accomplish desired contours for the tooth then you might need to remove enamel. Removing enamel is the outer hard surface of the tooth and some would attribute to weakening the tooth, but if it needs to be done to accomplish the desired goal then we reduce as little as neded.

It generally just adds to any voids or chipped areas, so it shouldn't damage them at all.
