Orthodontists have many tools that are used to move teeth in variable directions. Orthodontists use powerchains (or linked color-ties) to move teeth together and close spaces, or rotate teeth. Since your powerchain is not connected all the way across your teeth, it appears that your orthodontist is moving your teeth on both sides away from your blocked out tooth so that your blocked tooth will eventually have enough room to move forward. The best way to find out is to ask your orthodontist's office.
It does look like your teeth sit forward of your lip line and are putting strain on your lips. You might benefit from treatment with teeth being extracted so that the front teeth do not lean forward as they do now. I would advise an in-person consultation with an orthodontist to check out your options. I see that you are located near Beverly Hills, Dr. Dovi Prero has an office near you and could help guide you through your questions.
Braces or clear aligners can be used to fix the alignment of your lower teeth. You may need some reshaping between your lower teeth to get them to straighten properly. An in-office consultation with an orthodontist will help you understand your options for treatment. Happy smiles!
