Italian to English Medical Medical: Dentistry dental procedures

This is from an article in a dental journal, describing the history of a patient treated by the authors.

"Dal racconto anamnestico, si evince che 2 giorni prima la paziente si era recata dal proprio odontoiatra di fiducia per eseguire *terapie conservative*".

This is in a file that I am proofreading. The linguist translated this as "... she had gone to her dentist 2 days before for *conservative treatment*."

So I'm just verifying the translation ... I have a feeling that maybe it needs something different. To me, "conservative treatment" means nothing too radical, nothing too extensive or elaborate, just the minimum that needs to be done. I'm wondering if there is a different meaning for "terapie conservative" here, in this dental context. Or does "conservative treatment" (in English) have a special specific meaning in dentistry?

Grazie dell'aiuto.
