Sensodyne Repair & Protect Deep Repair, powered by NovaMin, is specifically formulated to help repair dentin deep inside the tooth and restore a protective mineral layer over exposed dentin.
Here's a more detailed look at why this toothpaste, and others with similar formulations, are effective:
-
Understanding Dentin and its Repair: Dentin is the layer of tooth structure beneath the enamel. When enamel erodes or recedes (e.g., due to gum recession), the dentin becomes exposed. This exposed dentin can lead to tooth sensitivity. Repairing dentin involves remineralization, a process where minerals are deposited back into the dentin structure to strengthen it and reduce sensitivity.
-
NovaMin Technology: NovaMin is a key ingredient in Sensodyne Repair & Protect Deep Repair. It releases calcium and phosphate, which are the building blocks of tooth mineral. These ions help to form a protective, tooth-like mineral layer over the exposed dentin, effectively repairing it.
-
How it Works:
- Exposure: When dentin is exposed, it becomes vulnerable to stimuli that cause sensitivity (hot, cold, sweet, acidic).
- NovaMin Action: The NovaMin particles in the toothpaste bind to the exposed dentin.
- Mineral Release: NovaMin releases calcium and phosphate ions.
- Remineralization: These ions precipitate and form a new layer of hydroxyapatite (the main mineral component of teeth) over the dentin tubules, effectively sealing them.
- Reduced Sensitivity: By sealing the tubules, the toothpaste helps to block the transmission of pain signals to the nerves in the tooth, reducing sensitivity.
-
Beyond Sensodyne Repair & Protect: While Sensodyne Repair & Protect Deep Repair is specifically highlighted, other toothpastes that promote remineralization may also aid in dentin repair. Look for toothpastes containing:
- Fluoride: Fluoride strengthens enamel and can help remineralize dentin.
- Hydroxyapatite: This is the mineral that makes up tooth enamel and dentin. Toothpastes with nano-hydroxyapatite can directly deposit this mineral onto exposed dentin.
- Stannous Fluoride: Some studies suggest stannous fluoride may be more effective than sodium fluoride in reducing sensitivity.
-
Important Considerations:
- Consult a Dentist: It's always best to consult with a dentist or dental hygienist for personalized recommendations. They can assess the extent of dentin exposure and recommend the most appropriate treatment plan.
- Proper Brushing Technique: Using a soft-bristled toothbrush and gentle brushing technique is crucial to prevent further enamel erosion and gum recession.
- Dietary Habits: Limiting acidic foods and drinks can also help protect enamel and dentin.
In summary, Sensodyne Repair & Protect Deep Repair, along with other remineralizing toothpastes, can be valuable tools in repairing exposed dentin and reducing tooth sensitivity, but a dentist's advice is always recommended.
