Introduction
Denture-related bad breath may be caused by poor oral hygiene, issues with denture materials, dental caries, gingivitis, gastritis, or other factors. It is important to maintain good personal oral hygiene, keep dentures and surrounding teeth clean, avoid using strongly irritating oral care products, and pay attention to other potential health conditions that could contribute to bad breath, in order to preserve both oral and overall health.
In general, bad breath associated with dentures may be caused by poor oral hygiene, issues with denture materials, dental caries, gingivitis, gastritis, or other factors. Treatment can include general measures and medication under the guidance of a healthcare provider. Specific causes are analyzed as follows:
1. Poor Oral Hygiene
When oral cleaning is inadequate, food debris can become trapped between the dentures and natural teeth or on the surface of the dentures, creating an ideal environment for bacterial growth. These bacteria break down food particles and produce volatile sulfur compounds and other odor-causing substances, leading to bad breath. It is important to maintain good oral hygiene and brush teeth regularly.
2. Denture Material Issues
Certain denture materials may be incompatible with the oral environment, causing allergic reactions or irritation that lead to bad breath. In daily life, it is advisable to switch to more suitable denture materials and avoid using oral care products with strong irritants.
3. Dental Caries (Tooth Decay)
Long-term consumption of high-sugar and acidic foods, along with improper oral hygiene, are primary causes of tooth decay. When teeth surrounding the dentures develop cavities, bacteria erode the tooth structure and produce unpleasant odors, resulting in bad breath. This may be accompanied by symptoms such as tooth pain and sensitivity. Treatment may involve medications such as sodium fluoride glycerin paste, artificial bezoar metronidazole capsules, or ibuprofen sustained-release capsules, as directed by a physician.
4. Gingivitis
Gingivitis is commonly caused by poor oral hygiene and plaque buildup. Improperly fitting dentures may exacerbate gingivitis, contributing to bad breath. Symptoms may include redness, swelling, and bleeding of the gums. Treatment under medical supervision may include metronidazole tablets, cefradine capsules, or iodine glycerin.
5. Gastritis
Bacterial infection, diabetes, kidney stones, and other conditions can trigger gastritis. Such diseases may cause stomach contents to produce large amounts of gases like hydrogen sulfide under the action of bacteria such as *Helicobacter pylori*. These gases are expelled through belching, leading to bad breath. Symptoms may also include nasal congestion and sore throat. Patients should follow medical advice to take medications such as omeprazole enteric-coated capsules, cimetidine tablets, or famotidine tablets.
To maintain oral and overall health, individuals should pay special attention to personal oral hygiene, keep dentures and surrounding teeth clean, avoid using irritating oral care products, and monitor other potential systemic health issues that may contribute to bad breath.
