You have to undergo orthodontic treatment. Extracting teeth for the purpose of orthodontic treatment will not affect your vision. Generally teeth with normal alignment will have only single point contact. So, maintaining oral hygiene by brushing and flossing is not difficult. But, when there is a malocclusion, especially crowding of teeth, instead of a single point contact, the teeth will have surface contact. Accumulation of food debris is more and brushing and flossing becomes very difficult. Oral hygiene cannot be maintained. So, Orthodontic treatment is essential. Extracting teeth to gain space for orthodontic treatment is harmless and it would not affect one's vision. Moreover, orthodontic treatment would improve your smile and confidence.
