Bacteria
Gauged ears can create a warm, moist environment that is ideal for bacteria growth. This can lead to a buildup of bacteria, which can produce a foul odor.
Earwax
Gauged ears can also cause an increase in earwax production. This earwax can build up and become impacted, which can also lead to a bad smell.
Infection
If the gauged ear becomes infected, this can also produce a foul odor. Infection is more likely to occur if the ear is not properly cleaned or if jewelry is inserted that is too large or not properly sterilized.
To prevent your gauged ears from smelling, it is important to keep them clean and dry. Wash your ears regularly with soap and water, and use a saline solution to clean the piercings. Avoid wearing jewelry that is too large or too tight, and only insert jewelry that is clean and sterilized.
