Quick answer: No it all is determined by what is going on on for your mouth (what work you want, present conditions, past private care, and many others). If your mouth is a multitude, with Zoom whitening or other whitening products, which you could nonetheless immediately (good for the Zoom laser about an hour appointment) whiten your tooth through several colorations...The fixing part nonetheless, absolutely will depend on what is going on on to your mouth. If you want straightening, veneers could also be utilized and to be able to take about two weeks in whole. If enamel are really crooked, then Orthodontic work (braces) perhaps needed, and in an effort to take months and months. Mostly teeth are so bad, a full mouth restoration is performed. And a full mouth restoration case normally takes years...Oral surgeons (implants), beauty dentists (veneers, white fillings), periodontists (gum surgical procedure), orthodontists (straithening with braces), medication time before other work can be achieved, and so forth. Like I mentioned, it all depends on whats occurring, what you want, and the way capable your general practitioner(s) is/are. Hope that helps.
