After many months of waiting, some orthodontic patients are incredibly disappointed to see that their teeth are a complete mess after the braces come off. Improper oral hygiene and a lack of dentist check-ups can lead to yellow teeth after braces, to white spot lesion, and even cavities on the tooth surfaces. Receiving orthodontic treatment puts you at risk of oral disease, as the teeth are harder to clean, and certain tooth surfaces remain hidden as there are brackets on top of them, leading to yellowness of the teeth after the braces come off. Damage can also be incurred from the appliance itself.
