27y/o and exploring braces. treatment includes using quad helix expander(8-10mo) in molar and braces at the same time to fix cross bite. does it work?
4 doctors weighed in across 2 answers
Be careful: If your cross bite is dental (upper teeth tipped inward) quad helix is modestly effective for adults. There are so many more effective tooth expanders available. If cross bite is skeletal (upper jaw too narrow when compared to lower) the jaw itself has to be widened, and in adults that means doing expansion coupled with surgery. Make sure you see a qualified Orthodontic Specialist for your care

It can: Traditional literature would say that expanders can not be used effectively past the age of puberty, but we have had surprisingly good results with patients into their 20's. That is not to say that it will definitely work for you-- at your age the bones may have fused to the point that an expander will have no effect, but as we have told our 20-something patients-- there's little harm in trying

I've had braces for 12 months, I had an expander for 6 months (its gone now), I have a powerchain (only on top teeth), no gaps between any teeth, and have had bands for 2 months. My bite looks really good. When will my braces most likely be off? Thx?
I have crowded teeth and they have some mobility. My orthodontist has said it is caused by pressure from crowding but with my regular brushing, it will not ever fall out. Should my teeth soon enough tighten a bit after I get braces and an expander?
