Hello
If the gap is less than 2mm you can opt for cosmetic veneers, crowns, laser filling or even a simple composite filling.
This could charge you between 2-8k
Since it is a front tooth.... If you are going for crowns would advise you to opt zirconia. Zirconia crowns have a superior quality and will charge from 10-15k per tooth.
You can also go with braces.... It will be a lengthy treatment and will charge you between 15k- 25k.
Next Steps
would advise you to visit a dentist.
A clinical checkup will give a better examination and thus a proper treatment plan
