Detailed answer

Hyperpigmentation refers to the darkening or discoloration of the skin caused by an excess production of melanin. It is mainly caused by factors such as sun exposure, hormonal changes, injuries or skin conditions.

Orthodontic braces or retainers, when worn properly, do not come into direct contact with the skin. They are designed to correct the alignment of teeth and enhance oral health. Hyperpigmentation is not a known side effect of using orthodontic braces or retainers.

However, it is possible for braces or retainers to cause some local irritation or inflammation in the mouth area, which could indirectly lead to hyperpigmentation as a result of increased production of melanin in the skin surrounding the mouth. To prevent this, it is essential to maintain good oral hygiene, follow the orthodontist's instructions, and report any discomfort or irritation to them.

If you are experiencing hyperpigmentation, it is advisable to consult a dermatologist who can evaluate your specific situation and identify any underlying causes or contributing factors. They can provide appropriate advice and treatment options tailored to your needs.
