Hello  you can opt for  clear aligner s.veneers are good  but as your age good for braces your  natural  teeth can be corrected  rather than  placing  some artificial  .

Hi..only frenectomy won't help. Braces are compulsory in your case. Temporary solution is composite veneers Regards

It might leed to closure of gaps The frenum surgery ELse you can go for veneers If maintained properly they can last 15-20 years Since yoh are young plz reconsider ortho treatment Bcoz any thing added to tooth has a life ! So it will eventually fail

You said you have a missing tooth! Ideally The tooth will require to be replaced either with implants or fixed prosthesis. But you say the gap is only 3mm . In that case you may opt for veneers or crowns depending on your case. Orthodontically even if you close this gap it will not look esthetic cause there will be no symmetry between teeth on left side and right side . This is because if you observe your front teeth each tooth looks different, it’s shape ,size. So even if u go for orthodontic treatment you will need esthetic correction in the form of veneers or something later.

Cosmetic smile correction, is the quickest to do the needful but the apt would be orthodontic methods / clear braces .think about it .

If the gap is around 3mm then you can try composite or veneers but some times your front teeth may look bigger if the gap is more and filled with composite You also have option of crowns but we need to judge all this seeing you clinically and also the anatomy and size of the teeth too matters Please put a pic for better answer

If aesthetic reason is something which stops you from thinking as Braces as an option then Go for Aligners . There are various brands available with the dentists. The best being Invisalign. Though with Aligners also you need to be patient enough and wait for the results after a couple of months or a year but looks like that would be the best modality of treatment in your case.
