From what I can observe in your photo, there appears to be some crowding in the lower front segment and some mal-alignment of the upper front segment too.
These are fairly straight forward problems to resolve with a course of orthodontics (braces). You will find that a simple course of either fixed or removable (e.g. Invisalign) orthodontics will leave you with aligned teeth, a stable bite and a nice smile!
There are other options besides orthodontics, for example using porcelain veneers or crowns to correct the shape and alignment of teeth. But orthodontics tends to be the least invasive and a superior clinical option if your primary objective is to align your teeth to improve your smile.
Generally speaking in Singapore fixed braces can range from $3000 onwards and a full course of Invisalign (clear aligners) can range from $6000 onwards.
I do hope this has been helpful to you
Kind regards,
