A "tooth gap" refers to a space or gap between two teeth, often seen in children as they lose their baby teeth and their adult teeth come in. This gap can also occur in adults due to various reasons, such as tooth loss, gum disease, or natural spacing of teeth. Tooth gaps can affect a person's smile and may influence their confidence. While some people embrace their tooth gaps as a unique feature, others may seek orthodontic treatment, such as braces or aligners, to close the gap and achieve a more uniform smile.
