Q. Hi Dr. Patel, I have a permanent retainer on my mandibular incisors for about 6 months now. Past 2 weeks I am noticing that my left mandibular canine is shifting a bit when my tongue puts slight pressure on it. This canine is the last tooth the retainer is attached to… I am worried about why this canine is not stable as my other teeth, and why is feels so loose. I am definelty not looking forward to letting my canine fall out… Like I said, you can’t see the canine moving, but I can feel it going back and forth… Is this something I should get checked right away? I am a dental hygiene student age 19
