If i have a loose tooth in the front on the bottom and i get that tooth pulled, can i then close that gap with invisible aligners?

Have yourself examined by a dentist for periodontal issues. Determine which teeth can remain and which teeth are hopeless. Then consult with an orthodontist to discuss treatment options for closing the spaces. Some things are possible with clear aligners, some are not.

If one space is closed, it affects the position, and therefore the occlusion, of all the other teeth. Seek evaluation by your General Dentist and a specialist Orthodontist. Looseness in one tooth signifies periodontal disease, which may not be localized to just that tooth, and which may require treatment by a gum specialist Orthodontist. Choose the practitioner, not the gadget.
