What to do if i still have baby teeth and im 18, i'm looking for an alternative for braces?

Invisalign: Invisalign is a possible choice, but if you still have primary teeth, then those would need to be extracted. If the secondary teeth are impacted, they will most likely need to be surgically exposed, and then brought into position with traditional orthodontics. Invisalign has its limitations.

Two issues:: The first issue is whether or not you need orthodontics due to a malocclusion (bad bite) or for esthetic reasons. The second issue is how to deal with the baby teeth. If your occlusion is bad, only conventional orthodontics or invisalign can improve that. If the baby teeth need to be removed, i would recommend implant supported crowns. You will need to discuss all these issues with your own dds.

2 choices: Non-surgical choice: move teeth into best possible positions orthodontically. Know that braces are twice as effective as clear aligners at moving teeth. Surgical choice: restorations to reshape or replace teeth. Best solution: have restorative dentist and orthodontist both examine you, consult with each other, and present you with the best choices.
