They care regardless of what professional program you’ve applied to - pharm, vet, optometry, etc.
In your case you need to show them why dentistry is the correct choice. Do so via shadowing hours, working in the dental office, and possibly having an LOR from a dentist. As well as your essays.
Because you declined your offer, you’re in better shape than had you accepted, matriculated, and then dropped out.
Just be prepared to thoughtfully answer the why dentistry question and why not whatever professional school you had applied to. The application asks only if you applied to other programs, I don’t know if it asks specifics but schools would probably ask you to clarify.
