At our periodontal practice, we focus on helping patients protect their gums because healthy gums are essential to a healthy smile. While brushing, flossing and routine dental visits are well-known tools in preventing gum disease, there is another natural defense that often goes unnoticed: saliva production.
Saliva is not just a source of moisture. It is a powerful tool your body uses to fight bacteria, balance acids and keep the mouth clean. Maintaining healthy saliva levels is an important part of preventing gum disease and preserving long-term oral health.
Saliva Cleanses the Gums and Teeth
One of saliva’s most important functions is to wash away food particles and bacteria. Every time you eat, bacteria feed on leftover sugars and starches. This results in plaque buildup, a sticky film that clings to the teeth and gums. If not removed, plaque leads to gingivitis and, over time, periodontitis, a serious gum infection that damages the soft tissue and destroys the bone that supports your teeth. It is the advanced stage of gum disease (also called periodontal disease) and can lead to tooth loss if not properly treated.
The good news is, saliva helps reduce plaque by rinsing away harmful oral debris. This natural cleansing effect limits how much bacteria can stick to the teeth and gumline between brushings.
It Neutralizes Harmful Acids
The acids produced by bacteria after meals can irritate gum tissue and wear away vital tooth enamel. Saliva contains compounds that help neutralize these acids. By maintaining a healthy pH in the mouth, saliva protects soft tissues from inflammation and supports the body’s natural ability to repair and defend itself.
Saliva Contains Natural Defenses
Saliva is packed with antimicrobial agents, such as enzymes and proteins, that help control the bacteria in your mouth. These substances support a healthy balance in the oral microbiome and reduce the risk of gum infections. This natural defense system is especially important for patients undergoing periodontal treatment, as it helps protect healing tissues from reinfection.
Since saliva serves as a first line of defense against harmful microbes, thanks to its abundance of antimicrobial agents such as hydrogen peroxide, lactoferrin and lysozyme, when saliva production is impaired, it can lead to a range of issues. These include difficulty with tasting, chewing and swallowing, and a higher risk of developing oral health problems like tooth decay, gum disease, oral thrush and even infections in the respiratory tract.
Moisture Promotes Healing and Comfort
Dry or irritated gum tissue is more vulnerable to injury and disease. Saliva helps keep the gums hydrated, which improves comfort and supports tissue health. After procedures such as scaling and root planing or gum graft surgery, saliva plays a role in the healing process by keeping the area moist and reducing the buildup of bacteria.
The Risk of Dry Mouth
Dry mouth, or xerostomia, occurs when the salivary glands fail to produce enough saliva. This condition is common among patients taking certain medications, as well as those with chronic health conditions or those experiencing hormonal changes.
Without enough saliva, oral bacteria can multiply more quickly, plaque accumulates faster and the gums become more prone to inflammation. Patients with dry mouth often notice sore gums, bad breath and a higher risk of tooth decay and gum disease.
If you have dry mouth, it is important to let your periodontist know.
How to Support Saliva Production
You can support healthy saliva flow by:
- Drinking water regularly throughout the day
- Chewing sugar-free gum or lozenges to stimulate saliva
- Avoiding tobacco, alcohol and excessive caffeine
- Practicing good oral hygiene habits at home
- Scheduling routine periodontal care
