Introduction

Bad breath associated with dental prostheses affects more than one in two wearers. This often-taboo problem can impact self-confidence, social interactions, and even overall oral hygiene.

The truth is simple:
a dental prosthesis that isn't properly maintained becomes a breeding ground for anaerobic bacteria, responsible for unpleasant odors.

In this article, you will discover:

• the 6 real causes of prosthesis-related halitosis,

• the home solutions that work,

• the mistakes that make bad breath worse,

1. Why does your prosthesis cause bad breath?

Bad breath is caused by anaerobic bacteria that settle in:

• the micro-cracks in the resin,

• moist areas,

• biofilm plaque,

• food debris.

These bacteria produce volatile sulfur compounds (VSCs), responsible for a smell of rotten egg, plastic, or dampness.

2. The 6 main causes

1. Biofilm buildup

Invisible, but extremely odorous.

Solution : UltraClean Pro+™ (42 kHz ultrasound)

---

2. Wearing the prosthesis at night

92% of bacterial growth occurs at night.

Solution : remove and store in SecureBox Pro™

---

3. Insufficient manual cleaning

Brushing is not enough to remove embedded bacteria.

Solution : FreshTab Pro™ (antibacterial effervescent)

---

4. Coated tongue

80% of bad odors come from the tongue.

Solution : CleanTongue Pro™ (silicone scraper)

---

5. Poor hydration

A dry mouth promotes VSCs.

Solution : drink + antibacterial spray PureSpray Pro™

---

6. Food residues

Get trapped under the prosthesis and ferment.

Solution : HydroJet Pro™ water flosser

---

3. Mistakes that make bad breath worse

• using toothpaste on the prosthesis

• wearing it at night

• storing it in a damp case

• exposing it to hot water

• drinking coffee/tea before cleaning it

• brushing too hard → micro-scratches → bacteria

---

4. Effective home solutions

1. Baking soda soak (1×/week)

→ naturally sanitizes
→ neutralizes some odors

---

2. Cleaning with mild soap

→ removes stagnant saliva
→ prevents abrasion

---

3. 3% hydrogen peroxide (occasional)

→ whitens stains
→ limited use to avoid damaging the resin

---

4. Tongue scraping

→ essential step to reduce overall odors

---
