I have the wide gaps and deepbite. Will this treatment fix that? (photo)

Most orthodontic problems are fixable. It just depends on what appliances are used to treat it. Not all of them work the same and can produce the same results.

We need more information on what "this treatment" is. Wide gaps and deep bite problems can certainly be corrected or at least improved by various orthodontic methods but we need to know which method is going to be used. Would also help to know if it is a Class I bite or a Class 2 bite. Looks like probably class 2 which is more difficult.
