if you have not-so-jialat teeth and higher budget, can go for invisalign

will be less noticeable also if that's what you're worried about.
but actually right, i also thought i had not-so-jialat teeth but when i went for consultation then the dentist told me my overbite is quite severe so itll take me abt 2 years to get it aligned nicely.. so you might want to consider going consultation first!!
