Hi Looking at the picture, the patient has a tongue thrusting habit where the tongue position is a little bit forward than normal. This pressure will cause gaps between teeth over time.

U need orthodontic treatment ideally. If you want quick solution u can go for veneers or zirconia crowns

Hie... there are three solutions : 1.orthodontic treatment with wire or without wire 2. Veneers of upper front two teeth 3. Caps on the teeth All these treatment has different time limit alongwith costing charges

Permanently solution is orthodontic treatment as it doesn't involve any tooth invasion. But braces need to be apolied to both upper and lower teeth in order to establish proper bite.

Hey there, Only front two teeth can be straightened with veneers! Long standing solution would be porcelain veneers. Low maintenance. Cheaper option would be composite veneers. However they might need some repair over a few years due to wear. These are some of the quickest ways of achieving your desired result. If you are open to the option of orthodontic treatment and willing to go in for braces/aligners then thats also an option. However you will have to invest in some time in that.
