Well, I guess you already know that braces are the treatment of choice for forwardly placed teeth. Add to that malalignments and spacing, braces can really help you.
There are other "cosmetic" options, though. Wherein you cut and add to teeth (trim the jutting out part and build up some part). Composite veneers, laminates and crowns are part of this treatment modality.
At the age of 23, when you should plan to have your teeth in a healthy condition for at least the next 50 years, I would recommend Orthodontics. Some options like clear aligners and lingual braces are available for those who cannot have the braces seen.
Next Steps
Reconsider Orthodontics, may be invisible options
Health Tips
Cosmetic solutions most often involve causing a lot of damage to the existing teeth and need a lifelong high maintenance.
