Should I just get my canine tooth pulled? (Photo)

Your narrow jaw is a problem in more than just cosmetic ways.  You have an increased risk of snoring, sleep apnea dur to a small airway.  Extracting or amputating teeth will make the problem worse.I suggest looking into the DNA Appliance and Epigenetic Orthodontics to gradually expand your maxilla and make room for all your teeth.Contraction Orthodontics vs Expansion Orthopedics / orthodonticsThe healthiest physiology will result from expansion not from contracting an underdeveloped maxilla.  Ira L Shapira DDS, D,ABDSM, D,AAPM, FICCMOChair, Alliance of TMD Organizations

The fastest way to get rid of that canine is to extract it. It is the most invasive option but it is also the fastest option. Your other teeth are fairly all in line so extracting the canine will not be that big of a deal for function or aesthetics.

Your upper jaw is narrow, and you have significant crowding.  That is why your upper canine tooth is completely sticking out of the upper arch.  Expanders usually work properly and well until our mid-teens (generally).  As an adult, any claims to significantly expand your upper jaw (without surgery), to the point that an extra tooth like yours can be fitted in, and without extractions, need to be considered carefully - as this is not a sound approach.  Please make sure you seek the advice of an Orthodontist (specialist) or a couple of orthodontists - not a general dentist who does orthodontics.  There is a difference.  Your case appears more involved and should be handled by someone who has 2-3 years of full time additional university education on how to move teeth and help shape your jaw.
