UPDATE...Adventures in Invisalign...

So, here are a few more updates on my quest for Invisalign. I've seen 2 more doctors in the last 2 days and I'm more confused than ever!!

Doctor 3:
Very nice lady, she has an office in the loop and in my home town. Oh, she is an Orthodontist. The first 2 doctors I saw were Dentists.
Treatment: She does NOT want to give me invisalign. Instead, she wants me to wear clear braces for 18 months. She says that clear braces would not only straighten out my teeth, but they would correct my bite. She would make room to straighten my teeth by widening the arch in my mouth, no teeth shaving or tooth removal. She also stated that if I went with Invisalign, that my teeth would probably revert to the way they are now. She also stated that she would have to put a permanent retainer behind my front teeth after treatment ends.
Duration: Clear Braces 18 months ----- Invisalign 12 months approx.
Price: A whopping $6,000 for Invisalign or Clear Braces

Doctor 4:
Incredibly hot guy, with a fabulous ass!! Va-Va-Va-Voom!!!!!! His initial consultation was the most thorough of ALL the dentists thus far. He took x-rays and did a small exam. He is an Orthodontist as well.
Treatment: He gave me several options, which I liked! Option 1: Correct my overbite with Invisalign. Option 2: Clear braces, this option has 2 different paths. Path 1: Remove 2 teeth to make room for my front teeth to be straightened out. Path 2: Shave a bit off each of my teeth to make room for my front teeth. At the end of treatment I would clear Invisalign like retainers at night.
Duration: Clear Braces - 18 Months ------ Invisalign 12 months approx.
Price: $5,100 - With some excellent payment options!!

Adventures in Invisalign...

I am gearing up to straighten out a couple of my teeth. So I have been talking to dentists and orthodontists regarding my teeth and Invisalign. I have spoken to 2 dentists and have 4 more consultations scheduled for Invisalign. Here is the consensus thus far...

Dentist 1:

Treatment: She would give me aligners just for my top teeth, and shave those teeth to make room to straighten out my teeth.

Duration: 1 Year

Price: $5,400

Dentist 2:

Treatment: Widen the arch of my upper teeth, creating space to move my teeth, thus widening my smile and giving me more upper lip support. No teeth shaving.

Duration: 5 Months

Price: $3,000 approx. (I don't have a set price yet)

I don't understand how these 2 opinions could be sooo different. I have several other appointments coming up, I will follow up here after each appointment. Hopefully, I can find what the real answer should be!
