If the glass gets damaged, the easier and safer solution is to replace the complete screen assembly since the glass, digitizer and LCD screen are bonded together tightly by the help of very strong adhesive, and it is very hard to separate neither of them for individuals. Though there is front glass replacement sold separately. The reason is that it is possible to remove the glass from the LCD, as long as you have special tools as well as professional skill. Otherwise, it is better to replace the whole assembly rather than just the glass.
