Without seeing any pics, I can't say without a doubt.  Invisalign can do some amazing things.  Actually, it's the doctor can do some amazing things with Invisalign.  It is totally doctor dependent so I'd advise you to see an orthodontist that is either Elite or Elite 1% and make sure they're an independent office and not part of a chain because Invisalign counts a chain with 50 offices as one doctor.   This makes it appear as if one office is the top Invisalign provider when the doctor in that one office may have only treated 10 total cases.

The first thing I'd do is talk to your doc about your concerns.  I'm not a fan of "6 month smiles" because it's really all marketing as shown by your "9" month smile that you're not happy with.  6 month smiles braces are used by general dentists and not orthodontists.  Normally, it takes a good bit longer to straighten teeth properly which is why orthodontists don't use these type of braces.  Your teeth definitely look better than where they started.  I would approach your doc with a "you'll catch more flies with honey than vinegar" approach.  Most docs will want to make you happy at no charge.  That's what I'd do.

I tell my patients to keep on with life if an attachment falls off.  These things can happen every now and again.  I wouldn't anticipate anything major happening.  Don't sweat it.  Point out which teeth are missing attachments and your doctor can evaluate if they'll put them back on or not.  Sometimes I don't add the attachment back on depending on the type of movement I'm doing if the aligners fit well.

Invisalign Teen was designed for situations just like yours.  Invisalign Teen allows you to lose your baby teeth and allows your adult teeth to still come in while you are straightening the rest of your teeth.  I would recommend seeing an orthodontist that is a Premier or higher provider.

Extracting that molar likely won't affect your chances of getting braces. I would recommend having your dentist check the white spot that's near your finger in that picture.
