Saliva lubricates, rinses, cleans, and neutralises acids. It helps us experience taste and is an important protective factor for your mouth. It’s truly an amazing fluid! A dry mouth is the subjective feeling of not having enough saliva to keep the mouth wet, a condition also known as xerostomia. It could also be you have decreased saliva production, known as hyposalivation, or both. Remember, dry mouth is not a disease. However, with less saliva, the teeth become more vulnerable to tooth decay (caries). The soft tissues, such as gums and tongue, in your mouth become sensitive and susceptible to infection and oral thrush.
