If the gap between the incisors is corrected using traditional orthodontic treatment to close the gap, the adult orthodontic treatment usually takes longer, taking 1-2 years to complete the entire treatment. In addition to orthodontic treatment, you can also choose to use porcelain veneers or all-ceramic crowns to close the gap between the incisors, these two methods of treatment is relatively short, usually 1-2 weeks to complete the treatment. The use of porcelain veneers to close the gap is also a relatively common clinical treatment, mainly after two steps of treatment: First, the lip surface of the teeth after grinding off a layer of modeling, sent to the processing plant to process the production of porcelain veneers, about 7-10 working days after the porcelain veneers can be processed out. Secondly, the clinician will cement the veneers into the patient’s mouth, and the whole procedure will take about 2 weeks.
