Yes Invisalign can sometimes cause yellow teeth.
Usually though you can have a dentist clean your teeth and remove that yellowing of the teeth if you have your teeth cleaned soon enough.
French Kissing or even just kissing is possible when you have Invisalign.
The Invisalign may make it more difficult to French Kiss or to just kiss someone but you can still kiss someone while wearing Invisalign.
The wearing of Invisalign is basically invisible to most people and you can easily still kiss someone while you're wearing your Invisalign.
The Invisalign does not affect your kissing ability.
When it comes to straightening and aligning your teeth and you're choosing between braces or Invisalign the Invisalign is much better than the braces.
The braces have a potential to cut your teeth and are less comfortable to wear and they need adjusted often.
But the Invisalign is much more comfortable to wear and does not have the potential to cut your gums.
So the Invisalign is much better for your teeth than braces.
The cost for Invisalign ranges from $3,000.00 to $5,000.00 depending on your location and the dentist you're getting the Invisalign from.
Some insurance will pay for part of the cost for Invisalign or even all of the cost for Invisalign so check with your dental health insurance plan to make sure they cover the cost for Invisalign.
If it's deemed medically necessary for you to have Invisalign to align your teeth then the dental health insurance will usually cover the cost of the Invisalign and treatments.
If it's not deemed medically necessary for your teeth and dental health then you may have to pay for the cost for Invisalign out of pocket.
You could get a personal loan to pay for the cost of Invisalign if the dental health insurance does not cover it.
