Hello If you had braces at 14 years of age, it is unlikely that any orthodontic wire or bracket component would suddenly become visible after so many years. What appears as a “metal-like stain” is more commonly due to tartar/calculus deposits, or staining. If there is no pain, swelling, food lodgement, or discomfort, it is not an emergency. However, I would recommend getting it examined by a dentist

Hello. As per your given history. It might be residual of retainer wire or might be stain.

1. Schedule a Routine Dental Check-up: Visit a dentist or an orthodontist for a professional clinical examination. They can easily verify if it is an intact retainer or if it requires attention. 2. Get a Professional Scaling (Cleaning): If the "stain" is actually tartar or external staining accumulated around the wire over the years, a professional dental cleaning will safely remove it. 3. Evaluate Retainer Integrity: The dentist will check if the retainer is still securely bonded to all teeth. If it has partially detached or if it is no longer needed, they can repair, replace, or safely remove it. 4. Maintain Diligent Oral Hygiene: Continue to clean thoroughly around the area using interdental brushes or floss threaders specifically designed to navigate under fixed retainer wires.

Hello Better to get it, checked by the dentist

Could be just extrinsic staining on teeth or else a bonded retainer if its on the inner surface of teeth ,since you mentioned you are unable to see.. Please visit dentist to get it checked clinically.

Hello Kindly get it checked properly from nearest dentist If those are stains then it can be cleaned with cleaning
