It is not normal to have gaps between teeth, if it is caused by congenital development, then it can be left untreated or orthodontically treated, if it appears slowly later in life, then it may be periodontal disease and need periodontal sequence treatment. Normally, in a standard occlusal relationship, the teeth are in point or surface contact with each other and there is no gap. Some people have some natural loose gaps between teeth due to genetic or developmental reasons, and these do not require special treatment. If aesthetics are important, orthodontic treatment can close the gaps. If there are no gaps in the early stages, and scattered gaps slowly appear with age, then it may be periodontal disease and require periodontal sequence treatment. It is recommended to go to the dentistry department of a regular hospital for consultation as early as possible, depending on the condition.
