Had braces when I was 15 years old, when braces were removed I got a plate (type of temporary braces to retain position)for upper jaw to put only for some time. Teeth were perfectly fine for many years until 4 years back when a slight gap started occuring in front 2 two teeth so I saw a doctor he said put the plate again for sometime a wire has to be put (on the backside of teeth) for around a year to retain them at same place, however i just used the plate things were fine for sometime even after leaving the usage of plate , now from few months again i can see a increasing gap in front two teeth and front 4 teeth coming out wards. What is the permanent cure?
