Hello!
There are many methods for irregular teeth, but older teeth need to look at periodontal conditions, and there are many indications for porcelain teeth. If the periodontal conditions are not good, you can't make porcelain teeth. The price range of porcelain teeth in Beijing is about 400 ~ 4000.
In your case, my suggestion is that you can go to more places, have a free check-up and listen to the doctor's advice face to face.
