Dry mouth, also known as xerostomia, is more than just an uncomfortable feeling. It can significantly increase your risk of developing cavities and other dental problems. Saliva plays a critical role in protecting your teeth and maintaining a healthy mouth. When saliva production decreases, the mouth loses one of its most important natural defense systems.
Saliva helps wash away food particles and harmful bacteria that collect on the teeth and gums throughout the day. It also neutralizes acids produced by bacteria after eating and drinking. Without enough saliva, these acids remain on the teeth longer, weakening the enamel and increasing the likelihood of tooth decay.
In addition, saliva contains important minerals such as calcium and phosphate that help repair and strengthen enamel through a process called remineralization. A dry mouth reduces the mouth’s ability to heal early damage before it becomes a cavity.
Many factors can contribute to dry mouth, including medications, mouth breathing, dehydration, stress, sleep disorders, radiation therapy, and certain medical conditions.
Common signs include difficulty swallowing, sticky saliva, dry lips, bad breath, and waking up with a dry mouth at night.
If you experience persistent dry mouth, it is important to seek professional care. Early intervention can help protect your teeth, improve comfort, and reduce your risk of cavities and gum disease.
