See your dentist to determine the cause of your problem and treatment to correct the misaligned movement of your teeth. Non-treatment of this type of problem can lead to early tooth loss.
Dr. Joe Ferraro
Sometimes, people develop gaps between teeth due to cavities, teeth fracturing, or gum disease. In the case of gum disease, the bone supporting the teeth is lost and the bite flares the upper front teeth outward towards the lips, which causes the gaps to develop. I would strongly recommend you see a dentist.
