Is the sentence correct?

We saw our Dentist at the park on Saturday.

Answer: I think dentist doesn't need to be capitalized

Right.

To confirm if the sentence "We saw our Dentist at the park on Saturday" is correct, we can analyze the capitalization rule for common nouns such as "dentist."

In general, common nouns do not require capitalization, unless they are at the beginning of a sentence or a part of a proper noun. Proper nouns, on the other hand, refer to specific names of people, places, or things, and should be capitalized.

In this case, if "dentist" is being used as a common noun to refer to a profession rather than a specific person's name, it does not need to be capitalized. Therefore, the corrected sentence would be:

"We saw our dentist at the park on Saturday."

It is important to note that if "Dentist" is the name or title of a particular individual, it would then be treated as a proper noun and capitalized accordingly.
