Patient: I am 28 years old, female, my teeth are straight, white and healthy, but I experienced periodontitis in 2006, and I got pregnant and had a child in 2007. Help me close the gap in my incisors. Luo Wei: Hello Ms. Yu! The best way is to do orthodontic treatment, which needs to be done in the orthodontic department. The advantage is that the effect will be better and will not affect the incisors, but the disadvantage is that you need to wear orthodontic braces for about 1 year. The disadvantage is that the resin has to be glued between the teeth, and the material may become discolored or even fall off after a long time. You can take time to come to the hospital for detailed examination and consultation.
