How to Remineralize Teeth: A Dentist Explains

To remineralize your teeth, it's essential to adopt a comprehensive oral routine including brushing your teeth regularly with remineralizing toothpaste and improve your lifestyle and habits, such as limiting eating starchy foods combined with reducing exposure to cigarettes and alcohol.

The primary goal of remineralizing toothpaste is to help repair and strengthen weakened enamel by depositing essential minerals, such as calcium and phosphate, back into your teeth. For example, nano hydroxyapatite toothpaste is great for remineralization because it is made of the same components as your natural tooth structure.

Further, using expandable floss and tongue scraping daily helps remove harmful substances that can otherwise lead to demineralization and tooth decay.

In this article, I'll explain everything you need to know about the demineralization process and how you can remineralize your teeth at home.

Understanding Tooth Demineralization

A Demineralizing Tooth


Demineralization
is the process in which acids, often produced by the bad bacteria in our mouths, remove essential minerals like calcium and phosphate from our teeth. Through this process, our enamel surface gets weakened, and this eventually leads to tooth decay.

Without intervention, demineralization and dental decay can then progress to full blown dental caries (also known as cavities).

Preventing demineralization and promoting tooth remineralization are essential for protecting your teeth and promoting good oral health. The most popular tools for preventing demineralization include nano hydroxyapatite or fluoride toothpaste.

Causes of Tooth Demineralization

Tooth demineralization is primarily caused by the interaction of acids with tooth enamel. These can be dietary acids or simply acids produced by the bad bacteria in our mouth.

Let's walk through some of the other causes of demineralization:

Bad Bacteria & Plaque

Dental plaque is a thin, sticky film that naturally forms on our teeth. It consists of bacteria colonies that feed on sugars and carbohydrates from the foods we consume.

As they metabolize these sugars, they produce acids as byproducts. These acids can gradually erode the minerals, primarily calcium and phosphate, from our teeth which leads to demineralization.

Regular brushing and flossing help remove dental plaque, reducing the presence of acid-producing bacteria and their harmful effects on enamel.

Dietary Acids

Consuming acidic foods and beverages can directly introduce acids into our mouths, disrupting our oral pH.

For example, citrus fruits, carbonated sodas, and fruit juices are naturally acidic. When these acidic substances come into contact with tooth enamel, they can weaken the enamel's mineral structure, making it more susceptible to demineralization.

Limiting the intake of acidic foods and practicing good oral hygiene can help mitigate the impact of these dietary acids on teeth.

Poor Oral Hygiene

Inadequate oral hygiene practices, such as infrequent or insufficient brushing and flossing, can lead to dental plaque accumulating on tooth surfaces.

When plaque is not regularly removed, it provides a breeding ground for acid-producing bacteria. These bacteria thrive in the plaque and continuously generate acids as they metabolize sugars.

The prolonged exposure of teeth to these acids can result in demineralization, making regular and thorough oral care essential for preventing enamel damage.

Dry Mouth

Saliva is known for its ability to neutralize acids and support the remineralization of enamel. It's an essential component of your oral microbiome.

However, conditions that reduce salivary flow, such as certain medications, medical conditions, or dehydration, can leave the mouth dry. In a dry mouth environment, acids are not effectively neutralized, and the protective effects of saliva are compromised.

This can lead to an increased risk of enamel demineralization and tooth decay, making it essential for individuals with dry mouth to manage this condition effectively.

To combat dry mouth, certain toothpastes and chewing gums contain xylitol, a compound that has been proven to promote saliva production and normalize oral pH.

Acid Reflux

Conditions like acid reflux (gastroesophageal reflux disease or GERD) or frequent vomiting expose teeth to stomach acids, which are highly acidic and corrosive.

When these strong acids come into contact with tooth enamel, they can rapidly erode the minerals from the enamel surface, leading to demineralization.

Individuals with these conditions are at an elevated risk of enamel damage, and managing acid reflux or vomiting episodes is crucial to protect dental health.

What is remineralization?

Teeth remineralization

Remineralization is a natural process in which essential minerals, primarily calcium and phosphate, are deposited back into the enamel (aka the outermost layer of your teeth). This process repairs and strengthens enamel that has been weakened or damaged by acids and bacteria, ultimately reducing your risk of tooth decay and cavities

While remineralization is a process that can take weeks or months to occur, brushing with nano hydroxyapatite toothpaste for two minutes daily, using expandable floss at least three times per week, and limiting acidic and sugary foods in your diet can help.

Overall, remineralization is a fundamental aspect of maintaining strong and healthy teeth, and it takes not only good oral hygiene practices to achieve but also the use of remineralizing toothpaste and a balanced diet.

Now that we understand the demineralization/remineralization process, let's walk through some tips for remineralizing teeth.

Brush with Nano Hydroxyapatite Toothpaste

Nano hydroxyapatite toothpaste contains tiny particles of a synthetic form of hydroxyapatite, a mineral naturally found in your teeth and bones.

Brushing with this toothpaste can help strengthen enamel by depositing nano hydroxyapatite particles onto tooth surfaces. These particles bond with enamel, fill in minor surface defects, and promote remineralization. In fact, studies show that nano hydroxyapatite is effective at remineralizing teeth and reducing sensitivity in as little as 8 weeks.

Using nano hydroxyapatite toothpaste as part of your daily oral care routine can contribute to maintaining strong and healthy teeth.

Floss with Expandable Floss Daily

Daily flossing with expandable floss is an excellent way to remove food particles and plaque from between your teeth and along the gumline. This practice supports overall oral health and reduces the risk of enamel demineralization by preventing the buildup of harmful bacteria and acids in these hard-to-reach areas.

We recommend using expandable floss at least three times per week but preferably daily for best results.

Use a Tongue Scraper Daily

SWIPE Tongue Scraper

Tongue scraping helps remove bacteria and debris from the tongue's surface, promoting fresher breath and reducing the presence of harmful microorganisms in the mouth.

Maintaining a cleaner oral environment can indirectly support remineralization by minimizing the impact of harmful bacteria.

Use Alcohol Free Mouthwash As Needed

SWISH Mouthwash

Alcohol-free mouthwash can be a gentle choice for maintaining oral hygiene. It helps freshen your breath, reduce the growth of harmful bacteria, and provide supplement your usual routine of brushing and flossing.

Using alkaline mouthwash can help maintain a favorable environment for remineralization, especially when needed for additional oral care.

Choose a Toothbrush with Soft Bristles

Opting for a toothbrush with soft bristles is essential to avoid damaging enamel and gums during brushing. A soft-bristled toothbrush effectively removes plaque and food particles without causing unnecessary abrasion or damage to your enamel.

Avoid Charcoal Toothpaste

Despite its popularity, charcoal toothpaste can be unecessarily abrasive and potentially harmful to enamel. Its abrasive nature can lead to enamel erosion, counteracting the remineralization process.

Instead, we recommend avoiding charcoal toothpaste choosing toothpaste with proven remineralizing agents like nano hydroxyapatite instead.

Avoid Sugary and Acidic Foods in Your Diet

Limiting the consumption of acidic and sugary foods and beverages is crucial for preventing enamel demineralization. These items can weaken enamel and contribute to dental issues.

To prevent issues with demineralization, we recommend that you reduce your consumption of acidic and sugary foods. Further, you can also rinse your mouth out with water or alcohol free mouthwash to neutralize the acidic and restore the natural pH of your mouth.

Stop Smoking Cigarettes

Smoking cigarettes can have detrimental effects on oral health, including an increased risk of gum disease, tooth decay, and oral cancer. Quitting smoking is a significant step toward supporting both your overall and dental health.

The Bottom Line: Remineralizing Teeth

Ultimately, we need to adopt a holistic approach to oral care for remineralization including brushing with nano hydroxyapatite, daily tossing with expandable floss, and using a tongue scraper.

Further, certain lifestyle changes like maintaining a diet low in acidic or sugary foods along with quitting smoking can certainly contribute to healthy, remineralized teeth.

By combining all of these practices into your daily life, you can actively support the remineralization of your teeth and ensure your long-term oral health.

Frequently Asked Questions

How long does it take to remineralize your teeth?

Studies show that remineralizing toothpaste with nano hydroxyapatite can promote remineralization in as little as 8 weeks.

That said, remineralization is a gradual process that can vary in duration depending on several factors. For example, the extent of enamel damage is a rate limiting factor as minor surface defects or early enamel lesions remineralizing more quickly than deeper or more extensive damage.

Can you really remineralize your teeth?

Yes, you can remineralize your teeth through a combination of proper oral care and healthy diet and lifestyle practices. Remineralization is a natural process that helps repair and strengthen enamel, reducing the risk of tooth decay and cavities. By brushing twice daily with nano hydroxyapatite toothpaste and using expandable floss to remove bacteria along the gemlike, you actively support the remineralization of your teeth.

How can I rebuild my teeth enamel naturally?

To naturally rebuild teeth enamel, you should brush daily with a remineralizing toothpaste with nano hydroxyapatite and limit your consumption of sugar, acidic foods, alcohol, and cigarettes. Remineralization is a natural process that helps repair and strengthen enamel, reducing the risk of tooth decay and cavities. By brushing twice daily with nano hydroxyapatite toothpaste and using expandable floss to remove bacteria along the gemlike, you actively support the remineralization of your teeth.

What mineral rebuilds teeth?

The primary minerals that play a crucial role in rebuilding teeth enamel are calcium and phosphate. These minerals are essential components of hydroxyapatite, a crystalline structure that makes up a significant portion of tooth enamel. Hydroxyapatite is responsible for the hardness and strength of our teeth. When our enamel is demineralized due to acids and bacteria, remineralization occurs as calcium and phosphate ions are deposited back into the enamel structure from our saliva or toothpaste. This process repairs, rebuilds, and strengthens our teeth.

What mineral deficiency causes tooth decay?
A deficiency in several minerals and nutrients can contribute to tooth decay, but one of the most significant deficiencies linked to this dental issue is a lack of calcium. Calcium is essential for maintaining the strength and mineral density of tooth enamel. Without proper calcium intake or brushing with a nano hydroxyapatite toothpaste daily, our enamel becomes more susceptible to demineralization by acids and bacteria, increasing the risk of tooth decay and cavities.
