Smile designing is an artificial way of getting the teeth arranged in shorter time..
But Orthodontics is the best and natural Way of treating irregular teeth. Please consult an orthodontist and get opinion regarding the recent aesthetic options available. Remember that natural teeth are always natural.
1 Metal braces
2 Ceramic braces
3 Invisible braces (lingual orthodontics)
These are the options for aligning irregular teeth. Best options for your friend can be decided after assessing treatment time, cost and treatment plan. An Orthodontist consultation would help.
Invisible braces offer an aesthetic and barely visible alternative to standard braces. The clear aligners (also called clear braces) are manufactured using advanced computer technology that predicts tooth movement, making it possible for the removable orthodontic appliance to gradually straighten teeth. You can opt for either Invisalign or clearpath aligners to straighten your teeth. Alternatively, you can opt for cosmetic dental procedures to correct the crowding only in the front teeth. But I would advise caution before undertaking any cosmetic procedures.
