Hi and welcome,
Wisdom teeth are the last teeth to erupt in the oral cavity and they are often impacted in bone. Horizontally impacted teeth have almost no chances of erupting straight or vertical in the oral cavity.
As you have been waiting for a year now , i suggest you to get the tooth extracted surgically approaching your dentist
There is no use waiting unncessary if the tooth is causing you pain and discomfort, because such impacted teeth may disturb the adjacent teeth,lead to caries , infection and bone loss ,they may radiate pain to ear and neck if kept for long so better get it removed.
It is a minor surgery done under local anesthesia
, and the wound after extraction is sutured in position for faster healing ,you just have to follow the course of medication and post extraction instructions so go for it.
