x-pur crystal bottle
In-Office Desensitizer

Ingenious, natural and fast-acting desensitizer


Mechanism of action

X-PUR Crystal is a proprietary blend of natural acids and salts that quickly form insoluble calcium oxalate crystals to provide effective patient relief for general root or exposed dentin sensitivity in only a few seconds. This innovative blend rapidly blocks the fluid flow to help provide relief from sensitivity.


• Cost-effective:
  • 1-2 drop(s) per site
  • 10ml bottle = 320 drops
• Easy application: no drying, isolation or curing necessary
• Long-lasting, quick and easy application (20 sec. saturate + 20 sec. rest)
• Non toxic: no gluma and no harm to gingival tissues
• Prevents the migration of bacteria towards the vital pulp
• Slows the demineralization process and promotes remineralization
• Use pre and post SRP and whitening, and under restorations


In-office desensitizer ideal for these situations:
• Crown preparation : before and after
• Exposed cementum and root dentin
• Heavy calculus along cervical neck that extends along the root surface
• Pain from removal of an orthodontic bracket
• Prophylaxis : before and after
• Re-wetting agent
• Temporization
• Under restorations (amalgams, composites, crowns and veneers, inlays and onlays)

Clinical uses

• Periodontitis
• Tooth sensitivity
• Whitening

Directions for use

Do not etch
1. Clean and rinse the area of all foreign debris (biofilm or other particles). X-PUR Crystal is more effective when the mouth is first rinsed with warm water and teeth gently brushed without the use of toothpaste.

2. Place 1 to 2 drop(s) in a clean dish of your choice or a dappen dish. More drops may be needed depending on the size and number of teeth to be treated.

3. Using a cotton plier, take a small cotton pellet and saturate it with X-PUR Crystal.

4. Gently rub the wet pellet of X-PUR Crystal onto the affected tooth by saturating the area for about 20 seconds. Allow to remain and gently air dry for 20 seconds without any air blast. X-PUR Crystal may be applied to a damp surface and dabbed around crown margins and onto the exposed tooth roots that are sensitive to cold or air stimuli. X-PUR Crystal will not harm soft tissue. You may gently rinse after 30 seconds.
5. If the desired relief is not immediately gained, then a second or third application may be made without any tissue damage.
