    Hello Dr Chamberland, thank you so much for your work and for education of patients around the world, My son just tuned 19 this week, he has impacted canines, the doctor recommended removal right the way which absolutely terrifies me, I was hoping if you can evaluate his x-ray to give as a hope it’s not to late to start treatment and save the teeth or a least one, thank you so much I’ll be happy to send X ray if it’s possible. thank you so much

    1. At 19, prognosis of forced eruption is favourable. I would likely try to pull it unless it is very deep in the mandible. You may send the xray via my professional FB page.

    2. At 19, prognosis of forced eruption is favourable. I would likely try to pull it unless it is very deep in the mandible.

      It could be a good solution to remove the canine if the space is close. 2 condition are require: cl II dental relationship of Cl I + crowding in the lower arch that would justify 2 lower premolar extraction.

      However, I would definitely try to pull the canine orthodontically first. Then reassess later. I hope that help.
