Is there a utility for mac that shows the information of an SSD like the health etc…?
If you're OK with Command Line utilities, you can always use smartmontools from http://www.smartmontools.org/.

You would need XCode to compile them from source (unless someone here knows binary distribution for Mac OSX), but if I remember correctly I had no issues compiling the package. 

I have an OCZ SSD retrofitted into my MBP 15" mid-2010 and I can use smartctl command to monitor various stats, including your Total Bytes Written (called here Lifetime_Writes) as well as Media Wearout Indicator (shown as percentage). 

To give you an idea, here's the example output: 

MacBook:~  smartctl -a /dev/disk0 
smartctl 6.0 2012-10-10 r3643 [x86_64-apple-darwin12.2.0] (local build)

The exact parameters and stats shown for your SSD might vary, but as it's a free tool, you can try and see for yourself!
