I have a gap in between my front two teeth due to ulcerated gingivitis, which has now cleared up. I’ve noticed that my gum has shrunk away from my teeth and sometimes they hurt when I bite crusty bread or an apple. One of my front teeth has moved slightly forward as well. I brush my teeth twice daily and use inter-dental brushes when cleaning my teeth, plus use a mouthwash that is designed to improve gum health.What would you advise to correct this gap?
