Oral manifestations of diabetes can include:
- Dry or burning mouth,
- Altered taste,
- Fungal infection,
- Swelling of salivary glands,
- Increased tooth decay,
- Progressive periodontitis.
A dry mouth or burning mouth is a common complaint among people with uncontrolled diabetes, but it is also a symptom of many diabetes medications. Oral dryness makes the soft tissues more susceptible to infection by fungal organisms such as Candida and is usually associated with poorly controlled diabetes.
While increased levels of decay have been found in association with uncontrolled or poorly controlled diabetes, most evidence suggests someone with well controlled diabetes experiences less tooth decay.
