She knows - its $800. I think she's trying to figure out if she has decent insurance, because there is the option of switching from her husband's plan to her plan.
And at this point, its worth looking at her benefits and delaying until she can enroll in her plan if the benefits are better.
Also, OP, you should know that there usually isn't a burning need for two phase braces. My daughter had them, and something like 80% of kids who have phase one will need phase 2. If you skip phase one and wait, phase two will take longer - but its rare that there are issues that REALLY should have been fixed by phase one braces. For us, two phases wasn't a financial stretch - if it is for you, get a second opinion on two phases. Orthodonists love it - its more money for them - and frankly, I loved having my daughters teen set on for less than a year - but its an expensive choice.
I would add too, you should see more than one orthodontist. Consults are usually free. Not only do prices vary (by a lot!) but so do treatment options. On the same kid, I have been told 2 phases, wait until later, want to pull teeth, no pulling teeth, ortho wants to make a custom appliance, etc., etc.,
I made my final decision by talking to their dentist. Without giving Orthodontist names, I told her the treatment options I was given. I have 3 kids, and she picked the same ortho for all 3.
In that mix, one waited to have braces and will have them for 2 years. 2 will have 2 phases. One needs teeth pulled the other did not.
Our dental insurance seems to change annually (ugh) Insurance has covered $1000 in one plan and $1500 the next plan. (not all kids had braces at the same time)
So check different orthodontist too. Don't be lured by the cheapest, especially if they want to pull teeth. That is done by an oral surgeon, and it may not be the cheapest option in the end, if you know what I mean. However, it doesnt take from the orhodontist benefit, and sometimes medical insurance picks up part of the tab.
Been there, done that... times 3
