Common Causes of Brown Residue on Retainers

a. Plaque and Tartar Accumulation:

  • Microbial Debris: Plaque, a sticky film of bacteria, can turn brown when it combines with food particles and minerals.

b. Dietary Habits:

  • Pigmented Foods and Beverages: Consuming foods and drinks rich in color, like coffee, tea, and certain fruits, can contribute to staining.
  • Smoking: Tobacco products can lead to stubborn brown discoloration on your retainer.

b. Dietary Awareness:

  • Hydration and Rinse: Drink water regularly, and consider rinsing your mouth after consuming pigmented substances.
