Can you tell me docs, is invisalign better in certain cases than metal braces?

Yes: If you want improvement of tooth positions and refuse to wear braces or standard removable appliances, invisalign type treatment is better as there's not much else you can do!

Choices: Both can provide you with a beautiful smile and each have their pros and cons. Invisalign will likely cost you more and take longer, but as an adult you may prefer how it looks while you are in treatment.

Better?: More esthetic...yes. Better...no. In the hands of a qualified Orthodontic Specialist, braces are >90% effective. Clear aligners about 41% effective. So it's a question of vanity vas efficacy.

If you have crowns: If most of your teeth are crowns it may be easier to use Invisalign instead of braces that would need to hold to the crowns
