Why Do Dentures Smell Bad Sometimes?

An unpleasant smell from a denture is a reason to look closely at both the appliance and your cleaning routine. Simon's explanation focuses on the deposits that can collect in places a quick rinse misses.

Where the smell can come from

Plaque and food debris can collect between the denture teeth and on the fitting surface underneath. These sheltered areas need cleaning too. A denture can look reasonably clean from the front while still carrying deposits on the side against your gums.

Look after your mouth as well

Take the denture out for cleaning and keep your gums, tongue and any remaining teeth clean. If you have natural teeth, continue their normal brushing and interdental care. Persistent bad breath should be assessed rather than assumed to come only from the denture.

When a professional clean may help

Simon suggests having a denture checked when deposits are difficult to remove. The team can assess its condition and discuss cleaning or polishing. If the material has deteriorated, cleaning alone may not solve the problem. There is no automatic replacement date: the condition, fit and your mouth all need to be considered.
