Premolar extraction orthodontics for overbite ruined my face. is there any way to fix this?

Yes: There may be several options available to establish facial support depending on where the deficiencies are. Get several opinions on all your options and a clear idea of your final goals.

Not so: Premolar extraction did not ruin your face. Bad mechanics and/or diagnosis maybe. The evidence is overwhelming: gianelly, ao 2003 drobocky ; smith, ajo 1989 young ; smith, ajo 1993 mclaughlin ; bennett, ao 1995 luppanapornlarp, et al ao 1993 johnson ; smith, ajo 1995 paquette, et al ajo 1992 boley et al ao 1999 bowman ; johnston ao 2000.

Apples and oranges: Premolars extractions are usually required when there is moderate to severe crowding or when there is a large horizontal overbite. If your overbite was both skeletal as well as dental, jaw surgery plus braces is often the best treatment. See a qualified orthodontic specialist for options.

Yes, within limits: You can get an improved result by seeing an orthodontist to reopen the spaces. Implants would have to be placed in this scenario. Probably better to find an orthodontist that doesn't routinely use extractions to resolve crowding.

Some critics exaggerate the harm from extraction orthodontics but a consultation with an orthodontist or two will give you an update on your current options. Sometimes teeth do need to come out to avoid gum complications.
