My dentist want to pull out my canine. (photo)

NO, NO, NO! Do NOT remove a single canine tooth. You clearly have excessive crowding but removing your canine tooth is definitely NOT the best way to resolve the crowding. Find a doctor who understands epigenetic orthodontics. You can easily save your canine teeth with proper orthodontic treatment. Canine teeth are extremely important teeth for aesthetics and function. Good luck!

You have very severe crowding.  I would give it a 9 on a scale of 1-10.  I hope you are seeing an orthodontist and he or she has explained the reasons for the teeth that need to be removed.

Canines are among the strongest teeth in the mouth but if the gum support around them is compromised, sometimes they are removed as part of orthodontic treatment.

Your gum tissue looks like you might need a through cleaning before starting orthodontic treatment.  Moving teeth if the gums are inflamed can lead to severe bone loss and even loss of teeth.

If this has not been discussed with you, get some other opinions.  

That said, you have very nicely shaped teeth and they look like you have taken good care of them despite the crowding that can make brushing difficult.  They will look very good when the crowding is corrected.
