What if my retainer smells even after cleaning?
If the retainer isn’t dried properly or if there are micro-cracks, bacteria can linger. Consistently consuming strong-smelling foods or drinks can also contribute to odor. If you notice a smell after cleaning, try a weekly soak with a retainer-cleaning tablet or use a baking soda paste. If the odor persists, contact your orthodontist, as there may be microscopic damage or material breakdown that requires professional help.
