Pericoronitis
Caries

Cysts/Tumors
[Orthodontic Purposes]

Prophylaxis
prevention of future pathology
controversial

Is Prophylactic Removal Warranted?
No
evidence of pathologic potential is mostly anecdotal
cost-benefit analysis does not support it
procedure is morbid and may cause lasting injury (sensory dysfunction)

Yes
surgery at younger age allows better periodontal healing, faster recovery, less risk of morbidity than later (age 30 or over)
delaying removal requires second anesthetic, second surgery, greater social costs

Yes (continued)
early surgery prevents later suffering
morbidity from surgery is low and only increases with age

    This may be a stupid question. My daughter had her records appointment recently. At the consultation, ortho told us one or both of her canines were impacted. They would most likely put the braces on and then 6 -8 months later we would do oral surgery to pull them down. At the records appt, they thought maybe just one canine was there. If there is just one, what would be the next step? We had made the appt for the spacers and braces, but ortho called, cancelled this appt and made another consultation appt where she has to have pan x-rays and then they will discuss with me. This may be a stupid question, but if you do not have the perm teeth to replace a baby tooth, do you still lose the baby tooth?
