My lower jaw is not aligned with my upper jaw.. it is smaller than my upper jaw. Therefore I might need mandibular expansion for fixing it. I read out over the internet that mandibular expansion doesn't work out well in adults. Will it work for me I'm 24? How much mandibular expansion cost? Is there any other non surgical procedure for correction of my crossbite?

Hi, i recently got self- ligating braces. I have to relocate to another city for work. Can I get my braces tightened from another dentist/orthodontist?  I haven't yet paid the full amount to my dentist for the treatment. So if I go to another dentist will this cost me extra? If yes, how much?

My lower set of teeth is slightly crooked.Last time I went for a dental checkup they said I have a possible deep bite.I don't personally want braces and If it's essential I would prefer an Invisalign.Every once in a while I get sensitivity in the slightly crooked part of my teeth.It comes and goes after sometime and comes back again after a month or so.I have the sensitivity right now and I have a feeling that flossing the bottom row of teeth has caused the are to be sensitive again.I'm pretty sure this pain will go in sometime.Is it concerning or serious? Would also like to know how much clear braces /Invisalign cost approximately? I am an 18 year old male
