I'm trying to find a correct Standard Irish translation for "Time does not heal all wounds". The most acceptable option I've been able to find is "ni leigheas gach creachta e an t-am" (I realize I don't have the punctuation correct). I believe this equates to "wounds do not heal all the time". If someone could please help me with a better option that translates better to "Time does not heal all wounds" it would be greatly appreciated!! Thanks in advance!

Actually, the suggestion you found is closer to what you wanted than you thought. Your translation of it is mistaken, probably because you were approaching the syntax from an English-speaking point of view. In Irish, the subject can often come at the end, as it does in a sentence like this. With a few changes, you could use:

Ní leigheas ar gach uile chréacht é an t-am
Time is not a cure for every wound

or, in a shorter version:

Ní leigheas ar gach créacht é an t-am
Time is not a cure for each/every wound

Edited to remove the genitive ending.

You are AWESOME! thank you so much

Out of curiosity, what does "ar" add to the sentence structure? I took 3 years of Spanish and none of it is helping me now lol

"Ar" is the preposition "on," but it's used in this kind of sentence in much the same way we would use "of" in English: Time is not the healer/cure of every wound. It may sound odd in English, but it makes perfect sense in Irish. Prepositions play a huge role in the Irish language, and their meaning can vary depending on what kind of idiom is used. In this case, "ar" is exactly what's needed.

Spanish, as a Romance language, is very, very different from a Celtic language such as Irish. So although learning any language helps a bit with learning a new one, there's not much specifically about Spanish that you could apply to Irish, other than such things as adjectives following the nouns they modify.

What about using lot rather than créacht? It sounds better with leigheas I think.
Ní leigheas gach loit (é) an t-am
Ní leigheas ar gach lot (é) an t-am.

Alternatively:

Ní gach créacht/lot/cneadh a (dh')íocann/leigheasann/chneasuigheann an t-am. (SL)
Ní gach créacht/lot/cneá a íocann/leigheasann/chneasaíonn an t-am. (CO)

If you use ar, no genitive case is needed: ... leigheas ar gach créacht ...

I noticed that that some sentences used the genitive and others used the dative(?) with a preposition,

leigheas gach loit, leigheas gach créachta....
vs
leigheas ar gach lot, leigheas ar gach créacht....

Would there be a difference in meaning or is it just two different ways of saying the same thing?

Oh and does "gach" count as a definite article in the genitive, like "mo"?
Do you need
Is é leigheas gach loit...or is leigheas gach loit...?

A lot of questions, I know, but I am sure someone here has the answers...

Ooops. of course you're right. Ive corrected my first post.
