14t works fine. Chain wear and/or sprocket wear can increase but it's not great in the scheme of things. Poor maintenance will wear them quicker.....
You don't need a new chain or rear sprocket so the 14t front is a very cheap viable way of finding out if you like the change.
When you're ready for a new chain etc. then look at going back to a stock front and up the rear by 3 teeth which will give you about the same ratio but you'd need a longer chain.
