How Long Does Remineralization Take? A Dentist Explains

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.

For minor enamel erosion or early stages of tooth decay (also known as white spot lesions), remineralization can often start to reverse the damage within a few weeks of consistent exposure to nano hydroxyapatite toothpaste.

However, for the remineralization process to effectively repair enamel and significantly reduce your risk of cavities, it needs to be an ongoing effort that includes maintaining a diet low in acidic and sugary foods, practicing good oral hygiene, and ensuring regular intake of remineralizing agents.

It's important to note that while remineralization can repair early enamel erosion and small lesions, you cannot remineralize cavities that have progressed to form holes or structural damage in the teeth.

In this article, I'll explain everything about how long remineralization takes and how to remineralize your teeth at home.

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 populars tools for preventing demineralization include nano hydroxyapatite or fluoride toothpaste.


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 main causes of demineralization:


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.


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.

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.


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.


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.


Demineralization involves the loss of minerals from tooth enamel due to acid exposure, which can lead to weakened enamel and tooth decay. Remineralization, on the other hand, is the natural process of depositing minerals back into the tooth structure which repairs and strengthens teeth.

Maintaining a balanced oral environment, practicing good oral hygiene, and using remineralizing toothpaste are essential for preventing demineralization and supporting the remineralization process to maintain healthy teeth.


Saliva plays a vital role in remineralization by:

  • maintaining a balanced pH in your mouth

  • neutralizing acidic conditions that promote demineralization

  • and providing essential minerals like calcium and phosphate

It also contains antimicrobial properties that control harmful bacteria, reducing acid production and contributing to a healthier oral environment.

Essentially, saliva forms a protective coating over your teeth, acting as a barrier against external factors and providing lubrication to help maintain enamel integrity.

Additionally, increased salivary flow during activities like chewing stimulates remineralization by delivering minerals to tooth surfaces and rinsing away acids and debris.

Okay, so what is 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.


Remineralizing toothpaste is a type of toothpaste formulated with ingredients that enhance the natural process of remineralization in tooth enamel.

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.

Remineralizing toothpaste can be particularly beneficial for individuals with early signs of enamel demineralization, tooth sensitivity, or a higher risk of cavities.

How to Remineralize Your Teeth

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


A jar of NOBS Toothpaste Tablets

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, stimulating a process called remineralization. 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.


Silk Expandable Floss

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.


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.


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.


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.


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.


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.


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.

Frequently Asked Questions

How can you tell if your teeth are remineralizing?
You can tell if your teeth are remineralizing through various signs, such as a decrease in tooth sensitivity, improved enamel strength, and a smoother tooth surface. Additionally, your dentist may observe less visible signs of demineralization during regular check-ups, such as the appearance of white spots diminishing or the reversal of early signs of decay. Consistent use of remineralizing toothpaste or other dental products containing ingredients like nano hydroxyapatite can also contribute to the remineralization process, leading to healthier teeth over time.

How can I speed up my tooth remineralization?
To expedite tooth remineralization, you can implement several strategies. Firstly, maintain good oral hygiene practices, including regular brushing and expandable flossing to remove plaque and bacteria. Consider using remineralizing toothpaste containing ingredients like nano hydroxyapatite, which can aid in remineralization. Avoid excessive consumption of sugary and acidic foods and beverages, as they can contribute to demineralization. Additionally, ensure you're getting enough calcium and vitamin D in your diet, as these nutrients are essential for strong teeth. Finally, visit your dentist regularly for professional cleanings and assessments to monitor your progress and receive personalized recommendations.

How long does bone remineralization take?
The duration of bone remineralization can vary depending on factors such as the extent of bone loss, individual health factors, and treatment approaches. In general, bone remineralization can begin within weeks to months of initiating appropriate treatment, such as dietary changes, supplementation, or medical interventions. However, complete restoration of bone density and strength may take several months to years, especially in cases of more severe bone loss or conditions like osteoporosis. It's crucial to follow healthcare provider recommendations and maintain a healthy lifestyle to support the process of bone remineralization effectively.

Does remineralization fix cavities?
Remineralization can potentially help reverse early-stage cavities by restoring minerals to the enamel, making it stronger and more resistant to decay. However, once a cavity has progressed beyond the initial stage and has formed a hole or pit in the tooth, remineralization alone may not be sufficient to repair the damage. At this point, the cavity typically requires dental intervention, such as a filling, to restore the tooth's structure and prevent further decay. Regular dental check-ups can help detect cavities early when remineralization may still be effective as a preventive measure.
