The Role of Saliva in Oral Health: Why It’s Important and How to Maintain It

Saliva plays a crucial role in maintaining oral health, yet it’s often overlooked in discussions about dental care. This natural fluid not only helps keep your mouth moist but also performs a variety of essential functions that protect your teeth and gums. At Quartz Dental, located at 9 Duchess Walk, London SE1 2SD, we emphasise the importance of saliva in oral health and provide tips on how to maintain healthy saliva production.

Why Saliva Is Important for Oral Health

1. Neutralises Acids

Saliva helps to neutralise acids produced by bacteria in your mouth after eating and drinking. Cavities can result from these acids' erosion of tooth enamel.

  • Acid Neutralisation: By neutralising acids, saliva protects your enamel from erosion and reduces the risk of tooth decay.
  • Buffering Capacity: Saliva’s buffering capacity helps maintain a stable pH level in your mouth, creating a less hospitable environment for harmful bacteria.
2. Aids in Digestion

Enzymes found in saliva, such as amylase, initiate the breakdown of food as soon as you start chewing.

  • Food Breakdown: These enzymes help break down starches into simpler sugars, making it easier to digest food.
  • Swallowing Aid: Saliva moistens food, forming a bolus that is easier to swallow and digest.
3. Protects Teeth from Decay

Saliva provides a constant flow of essential minerals, such as calcium and phosphate, to your teeth, which helps strengthen enamel and repair early signs of decay.

  • Remineralisation: Saliva helps in the remineralisation process, repairing small areas of enamel that have begun to break down.
  • Decay Prevention: The minerals in saliva contribute to stronger enamel, reducing the risk of cavities.
4. Washes Away Food Particles and Bacteria

Saliva acts as a natural cleanser for your mouth, washing away food particles and bacteria that can lead to plaque buildup and bad breath.

  • Plaque Prevention: By washing away debris, saliva reduces the amount of plaque on your teeth, helping to prevent cavities and gum disease.
  • Bacterial Control: Saliva contains antimicrobial agents that help control the population of harmful bacteria in your mouth.
5. Supports Healthy Gums

Adequate saliva flow helps keep your gums healthy by preventing dryness and irritation, which can lead to gum disease.

  • Gum Moisturisation: Saliva keeps your gums moist, preventing them from becoming dry and irritated.
  • Protect Your Oral Health: By avoiding tobacco, you reduce your risk of developing serious oral health problems and improve your overall well-being.

Causes and Symptoms of Dry Mouth (Xerostomia)

When your saliva glands don't create enough saliva, you get dry mouth, also known as xerostomia. If left untreated, this illness can result in a number of oral health problems.

Causes of Dry Mouth
  • Medications: Certain medications, such as antihistamines, decongestants, painkillers, and antidepressants, can reduce saliva production.
  • Medical Conditions: Conditions like diabetes, Sjogren’s syndrome, and Parkinson’s disease can cause dry mouth.
  • Dehydration: Lack of adequate water intake can lead to dehydration and reduced saliva flow.
  • Lifestyle Factors: Aside from caffeine, alcohol, and smoking, these factors can also cause dry mouth.
Symptoms of Dry Mouth
  • Dry or Sticky Feeling: A persistent feeling of dryness or stickiness in the mouth.
  • Bad Breath: Chronic bad breath due to reduced saliva production and increased bacterial growth.
  • Difficulty Swallowing or Chewing: A lack of saliva can make it difficult to swallow or chew food.
  • Sore Throat or Hoarseness: Dry mouth can lead to a sore throat, hoarseness, or dry nasal passages.
  • Increased Tooth Decay: Without enough saliva, the risk of tooth decay and gum disease increases.

How to Maintain Healthy Saliva Production

1. Stay Hydrated

Drinking plenty of water is one of the simplest and most effective ways to maintain healthy saliva production.

  • Daily Water Intake: Aim to drink at least eight glasses of water a day to keep your mouth moist and support saliva production.
  • Sip Throughout the Day: Keep a water bottle with you and sip water regularly, especially if you feel your mouth getting dry.
2. Chew Sugar-Free Gum

Chewing sugar-free gum stimulates saliva flow, helping to keep your mouth moist and clean.

  • Chewing Action: The act of chewing increases saliva production, which helps wash away food particles and neutralise acids.
  • Choose Xylitol: Sugar-free gum with xylitol is especially beneficial as it helps reduce the risk of tooth decay.
3. Avoid Dehydrating Substances

Certain drugs can cause dry mouth by decreasing salivary flow.

  • Limit Caffeine and Alcohol: Both caffeine and alcohol can dehydrate your body and reduce saliva flow. Opt for water or herbal teas instead.
  • Quit Smoking: Smoking can dry out your mouth and increase the risk of gum disease. Quitting smoking is beneficial for your overall oral health.
4. Use a Humidifier

Using a humidifier in your bedroom at night can help keep the air moist, reducing the likelihood of waking up with a dry mouth.

  • Nighttime Relief: A humidifier adds moisture to the air, which can help alleviate dry mouth symptoms while you sleep.
5. Consider Saliva Substitutes

If you struggle with chronic dry mouth, over-the-counter saliva substitutes and oral rinses can provide relief.

  • Artificial Saliva: Saliva substitutes can help mimic the effects of natural saliva, keeping your mouth moist and comfortable.
  • Oral Rinses: Some oral rinses are specifically formulated for dry mouth and can help soothe and protect your oral tissues.
