It depends on how severe the case is or what type of treatment works best for you. I would recommend consulting with an orthodontist that will determine the best treatment for you.
Thank you for your question.
Hope this helps.
Congrats on deciding to have straighter teeth. Both invisalign and traditional braces have pros and cons to them, but in the end they will both do a pretty good job of straightening your teeth.
The first thing you should answer to yourself is whether you are concerned with only your front teeth and whether you want your back teeth straightened or not.
Also you should talk to whoever is providing the services, they may have preference based on the location of your teeth currently. If your preference does not match up with their preference then try a different dentist.
Best of luck to you
