Wondering if it's absolutely necessary that i have the wisdom tooth removed or will it eventually turn out alright?

Depends.: If a wisdom tooth has fully erupted and is in alignment, no need to remove it. Whether or not to remove asymptomatic 3rd molars depends on many factors. See a board certified oral surgeon for an expert opinion. At age 42, the risks of removal are higher.

That depends: If they are bothering you and/or have an infection than the only way to solve this problem is to have them removed. As this can be complicated in an adult you must have this done by an oral surgeon, not a general dentist. If they do not bother you and do not show signs a cysts forming upon radiographic exam, than leave then alone. Your dentist and/or oral surgeon should be able to guild you.

Exam/consult: Wisdom teeth may erupt correctly and not create any problems. But since the teeth are so far back, it is often hard to keep the teeth free or plague and hard to floss, often leading to decay, gum problems or both. I you get the upper wisdom tooth out, it is wise to get the opposing one out to avoid problems with eruption of the opposing tooth. I suggest a consult with an oral surgeon.
