It’s the main accurate way, at least for living trees.
There are other methods but none really have a proven track record of accuracy the way tree-ring based methods do.
For well documented trees that coexisted with literate cultures, historical records can be used, though these records can sometimes be wrong. Some trees have ages from oral tradition too but these are difficult to verify.

They usually use a coring device. It doesn’t do significant damage to the tree.
