Importance of Balancing the pH of Mouth

Balanced pH of the mouth is very important to teeth health. Your mouth is a pH environment, and the balance of good to bad bacteria in your putting impacts your teeth, gum health, and even your breath. In this post, we will explore the world of pH – what it is, why it matters for your mouth, and how you can keep your oral health at its best by maintaining a stable pH as advised by family dentistry reno.

What is pH?

PH is a scale that ranges from 0 to 14, and it measures the acidity or alkalinity of an aqueous solution. A neutral pH level is set at a value of 7, with anything lower than this considered to be acidic and anything greater than this is alkaline (or basic). In terms of oral health care, your salivary pH is an important factor in keeping a healthy environment in your mouth, and care for such aspects during our initial tests.

The Right pH for Oral Health

An average pH level that indicates being healthy for the mouth is around 6.5 to 7.5. But when the pH falls below 5.5 (which is pretty acidic), all that acid causes demineralization of the tooth enamel — meaning it sucks minerals out of it, weakening the teeth and making them more prone to cavities and decay.

The Importance of pH Balancing Your Mouth

Prevention of Tooth Decay:

  • Acidic Environment: 

A mouth that is too acidic may wear down enamel which also increases the vulnerability of tooth decay. The acid allows these bacteria to thrive in the virtually undisturbed cavemen, and chomp through sugar creating even more acid.

  • Aiding in the Neutralizing Acid: 

Balanced pH can help neutralize acids in the mouth to provide a defense against enamel erosion and cavities.

Healthy Gum Tissue:

Increased acidity contributes to gum inflammation and, ultimately, periodontal disease. A proper pH prepares the area for healthy gum tissue and can help prevent gingivitis and other problems associated with the gums.

Balanced Oral Microbiome:

  • Good Bacteria:

A healthy balance of microbes stimulates good bacteria that thrive on a neutral pH. Protective bacteria will only flourish in a balanced pH environment helps fight against decay causing harmful bacteria as well as more aggressive tissue damaging bacteria creating a step for gum disease.

  • Pathogenic Bacteria: 

An imbalance in pH can cause dangerous bacteria to thrive which are the source of dental problems like bad breath, cavities, and gum diseases.

Fresh Breath:

Bacterial: Most (80-90%) transitionally colonized kids have high numbers of sulfur-producing bacteria, which are caused by a sulfur compound that makes them odorous. It maintains a healthy pH to do this, which in turn keeps the bacteria in check, leading to fresher breath.

What Influences The pH in Your Mouth


Consuming acidic food and beverages like citrus fruits, soft drinks, and wine can reduce the pH in your mouth; this is a good environment for enamel erosion as well as bacterial growth. Sugary foods are the perfect fuel for acid-producing bacteria, keeping pH lower and increasing cavities.

Saliva Production:

The saliva in the mouth serves as a natural buffer, Neutralising the acids and balancing the pH. An important recent study demonstrated that lack of saliva (dehydration, some medications, or medical conditions) decreases this buffering capacity. A sufficient saliva flow can wash away remnants of food and bacteria to prevent it from causing harm to your teeth and gums.

Oral Hygiene Practices:

Brushing and flossing are two of the most effective ways to remove food particles and plaque, which can limit the amount of acid that bacteria produce. Mouthwashes that have fluorides can strengthen enamel and balance the mouth’s pH.

Keeping a balanced pH level in your mouth is crucial as this will help contribute to the health of your teeth making sure that bacteria and plaque do not develop causing various dental issues. Simply by eating the right foods, drinking your water, caring for your teeth, and visiting your dentist, you can ensure that the pH level is optimum. By keeping your smile healthy you can keep your teeth from decay, maintain fresh breath, and keep your gums in good condition. So keep in mind – that a healthy smile starts with a balanced pH.
