Even if your wisdom teeth don't bother you, do you still need them removed?

I had an appointment today, and dentist told me that my wisdom teeth needed to be removed for the prevention of future problems. I am little bit scared of going to dentist that's why i was kind of nervous so he tried to explain me that in most cases wisdom teeth aren't removed until they cause problem due to either patients scared to get them removed or they ignore

Should i get my wisdom teeth removed?

Your xrays may show that there is not enough room for the wisdom teeth, or that they are in crooked, etc. Ask your dentist to explain why he thinks they need to come out. I had the opposite problem, with dentists telling me for years that I just needed to let them come in. After years of pain, an oral surgeon removed all 4. He said they were poorly developed and two of them were growing into the jaw. He had to cut those ones out. Just like with a doctor, you need a specific explanation, and if you are uncomfortable about the explanation, get a second opinion and another set of xrays.

Both of my wisdom teeth have already come in, upper left and lower left. He said that lower left wisdom tooth has come in rotated, i've looked and it's slightly rotated, it isn't fully aligned with my molar teeth. He said if i don't want to get them removed, it is okay but he adviced me to get them removed.

Should i get my lower left wisdom tooth removed or both of my wisdom teeth removed or i don't need to get them removed?

You don't want to have one on the bottom and missing one on the top or vice versa.  I think that is not good for your bite.

shortcircuited is correct.
