Thank you for the enquiry. It seems likely to me based on your description that there is pain due to the biting trauma from the upper tooth that is biting on the lower gum partially covering the lower left wisdom tooth.
Dr Gerald has given a thorough description of what should be done and I agree with all that he has said.
An alternative solution to relieve the pain would be to do something called crown lengthening. Crown lengthening is as follows:
Basically its to uncover the gum over the tooth that is causing pain and this procedure is medisave claimable. I do feel that you should consider this rather than extraction since you do have a fully functional wisdom tooth that is upright tooth.
Hope this helps and all the best!
Warm regards,
Dr Beth Seow
