A diastema is a space or gap between two teeth, most commonly noticeable between the two front teeth. It can occur anywhere in the mouth but is most noticeable in the front. Diastema is a normal feature in many species of mammals, especially herbivores, but only humans can seek dental care to correct the problem. The condition can be caused by a disproportionate relationship between the jaw and the size of the teeth, alignment problems, protruding teeth, or oversized tissue. In some cultures, diastema is considered a sign of attractiveness and fertility. Treatment options for diastema include orthodontics, composite fillings, veneers, crowns, and braces. In some cases, psychological counseling can be an option to avoid unnecessary treatments, and many people choose to embrace the gap between their teeth as a unique characteristic of beauty. Its important to note that diastema is usually a cosmetic concern and does not have a negative impact on oral health or function.
