For many, tooth sensitivity is a recurring barrier to enjoying life’s simple pleasures. While traditional sensitivity toothpastes focus on numbing the nerve, Sensodyne Repair and Protect (70g) takes a more advanced, structural approach. It is a daily fluoride toothpaste that is clinically proven to not only provide relief but to actually repair the sensitive areas of your teeth.

Utilizing patented NovaMin technology, this toothpaste seeks out the tiny holes in the dentin (the vulnerable inner layer of the tooth) and builds a robust, tooth-like layer over them. The 70g tube is the standard size for those seeking a long-term solution to sensitivity, providing approximately two months of restorative care when used as directed.

The Innovation: Understanding NovaMin Technology

The standout feature of Sensodyne Repair and Protect is its use of NovaMin, a breakthrough calcium-phosphate technology originally developed for bone regeneration. Unlike the Potassium Nitrate found in the Freshmint variant (which calms the nerve), NovaMin provides a mechanical solution to a mechanical problem.

How the Repair Process Works:

Scanning and Targeting: As you brush, NovaMin particles are activated by saliva. They seek out areas where the protective enamel has worn away and the underlying dentin is exposed.

Building the Shield: Once it finds these vulnerable spots, the technology reacts with oral fluids to form a hydroxyapatite-like layer—the same mineral that makes up your natural teeth.

Physical Reinforcement: This new layer is harder than the underlying dentin, effectively "plugging" the microscopic tubules that lead to the nerve. This prevents triggers like cold air or hot liquids from ever reaching the nerve in the first place.

Comprehensive Oral Care Benefits

Beyond its unique repairing capabilities, Sensodyne Repair and Protect serves as a high-performance daily toothpaste that covers all aspects of oral hygiene.

1. Permanent Sensitivity Protection

With twice-daily brushing, the repaired layer is continuously reinforced. This provides long-lasting protection that doesn't just mask the pain but addresses the root cause of sensitivity.

2. Strengthens Enamel with Fluoride

In addition to the NovaMin technology, the formula contains a therapeutic level of fluoride. This helps to strengthen the remaining natural enamel, making it more resistant to acid erosion caused by everyday foods and drinks.

3. Plaque Control and Gum Health

Healthy gums are the first line of defense against sensitivity. This toothpaste effectively removes bacterial plaque, helping to prevent gum recession—the leading cause of exposed dentin. By keeping the gums tight and healthy, it reduces the likelihood of new sensitive areas developing.

4. Freshness and Cleanliness

Despite its advanced medical-grade technology, the paste offers a clean, refreshing taste. It leaves the mouth feeling sanitized and the breath minty, ensuring you don't sacrifice the "clean" feeling of a cosmetic toothpaste for the benefits of a clinical one.

Usage Instructions for Best Results

To allow the NovaMin technology to bond effectively with the tooth surface, specific brushing habits are recommended:

Brush Twice Daily: Consistency is key. The "repair" layer needs daily maintenance to stay strong.

Technique: Apply a pea-sized amount to a soft-bristled brush. Brush all surfaces of the teeth for at least two minutes.

Avoid Immediate Rinsing: After brushing, spit out the excess paste but try to avoid rinsing your mouth with water immediately. This keeps the active minerals in contact with the teeth for a longer duration, maximizing the repair phase.

Dry Brush Tip: For even better activation of NovaMin, some experts suggest applying the paste to a dry toothbrush before adding water.

Key Ingredients

Active Ingredient: Calcium Sodium Phosphosilicate (NovaMin) - The repairing agent.

Enamel Protection: Sodium Fluoride (1450 ppm) - For cavity prevention and remineralization.

Inactive Ingredients: Glycerin, PEG-8, Silica, Sodium Methyl Cocoyl Taurate, Sodium Saccharin, Aroma (Mint Flavor).

Why the 70g Size is Ideal

The 70g tube is meticulously designed for regular home use.

Ergonomic Design: The stand-up cap ensures that the paste is always ready at the nozzle, reducing waste and keeping your bathroom counter tidy.

Longevity: A single 70g tube typically lasts between 6 to 8 weeks for a single user, allowing enough time for the NovaMin technology to fully establish a protective layer and for the user to feel the clinical difference.

Safety and Guidance

Professional Consultation: If your sensitivity symptoms persist after a few weeks, visit your dentist. Sensitivity can be a symptom of a cracked tooth or a deep cavity that requires professional intervention.

Age Recommendation: This product is generally recommended for adults and children over 12 years of age.

Storage: Store in a cool, dry place and keep the cap closed to prevent the NovaMin from reacting with moisture in the air.

Conclusion

Sensodyne Repair and Protect (70g) represents the pinnacle of sensitivity science. By moving beyond simple pain relief and into the realm of active dental repair, it offers a more permanent sense of security for those with vulnerable teeth. Whether your sensitivity is caused by aggressive brushing, acidic diets, or natural wear, this toothpaste provides the structural reinforcement needed to enjoy a life free from dental discomfort.
