The Role of Saliva in Oral Health
Saliva plays a vital role in maintaining your oral health. Saliva is produced by the salivary glands and helps protect your teeth and gums.
One of saliva's primary functions is to wash away food particles and neutralize acids (these acids can erode the tooth's enamel and cause cavities) produced by bacteria. Saliva contains bicarbonate which helps balance pH levels and further reduce acid damage.
Additionally, saliva is rich in minerals like calcium and phosphate which help in the remineralization of the enamel (process where minerals, like calcium and phosphate, are added back to tooth enamel, helping to strengthen it) This process helps repair early signs of tooth decay and strengthens teeth over time. Saliva also contains antimicrobial agents, including lysozymes and antibodies, which help combat harmful bacteria and reduce the risk of gum disease.
Furthermore, saliva plays a crucial role in digestion. It contains enzymes such as amylase, which begin breaking down carbohydrates before food reaches the stomach. Saliva also aids in swallowing and enhances taste perception by dissolving food particles.
A lack of saliva, known as dry mouth or xerostomia, can lead to various oral health problems, including bad breath, tooth decay, and gum infections. Staying hydrated, chewing sugar-free gum, and avoiding tobacco can help maintain healthy saliva production.
