How does potassium nitrate reduce tooth sensitivity

Special care can reduce tooth sensitivity

GUM® SensiVital® + is a new combination of toothpaste and mouth rinse with an effective double action that can bring about a rapid and long-lasting alleviation of dentin hypersensitivity. In addition, when it comes to oral hygiene, it is advisable to ensure particularly gentle cleaning, as with the new battery-operated GUM® ActiVital® Sonic sonic toothbrush, which vibrates with 12,000 vibrations / min. gently and thoroughly cleans the teeth and stimulates the gums.

Dentinal hypersensitivity, also known as dentinal hypersensitivity (DH), is a widespread condition affecting 42% of the adult population 1 . Characteristic complaints are short, stabbing pains in response to thermal, chemical, mechanical, osmotic, or stimuli generated by air currents. Typical triggers are cold or warm / hot food and drinks, sweets or sour treats, contact with food or during dental care, and breathing in cold air. The pain intensity is individual and variable, it ranges from minor to severe. Affected people complain of difficulty in eating and try to avoid the trigger as much as possible. In this context, daily oral hygiene is not infrequently neglected.

Exposed dentinal tubules responsible for pain

DH can have many causes, as a result of which there is exposed dentinal tubules. Dentin has a high water content, the tubules of which are filled with fluid. If the dentin is exposed, the liquid reacts to external stimuli with faster movements within the tubules and thus activates the mechanoreceptors of the free nerve endings in the pulp. Cold contracts the tubular fluid, creates a rapid outward fluid flow and leads to sharp, sharp pain. In the case of heat, on the other hand, a current develops towards the pulp (inward fluid), which is associated with dull, less severe pain. Hypersensitive dentin has 8 times more tubules with a diameter that is 2 times larger than insensitive dentin2 .

Dentin can be exposed on the one hand by the loss of tooth enamel and on the other hand by receding gums. Loss of enamel can result from abrasion (attrition, abfraction) or bruxism, from excessive consumption of soft drinks / fruit juices, excessive use of tooth whitening products or persistently excessive pressure when brushing teeth. A gingival recession occurs with acute or chronic periodontitis, possibly after periodontal or orthodontic treatments or as a result of incorrect oral hygiene. The extent of DH is primarily dependent on the extent of the exposed dentin and, to some extent, on the age of the patient. If left untreated, DH can adversely affect the general health of the patient.

Close dentinal tubules, improve oral hygiene

The aim of DH therapy is to seal the exposed dentinal tubules. The common chemical agents used for this purpose include toothpastes and mouthwashes with special ingredients, as they have a number of advantages: They can be used by the patient themselves, are non-invasive, inexpensive and are widely accepted. In addition to the use of these products, a simultaneous change in oral hygiene with the use of a soft toothbrush and gentle vertical movements when brushing from “red to white” as well as gentle interdental cleaning is important. The battery-operated GUM® ActiVital® Sonic sonic toothbrush, which vibrates with 12,000 vibrations / min. gently cleans the teeth and stimulates the gums. The microfine bristle tips reach the interdental spaces much more effectively than a manual toothbrush and remove many times more plaque in the gingival sulcus. The handle of the sonic toothbrush is ergonomically shaped and the brush head and battery are interchangeable.

GUM® SensiVital® + closes, seals, strengthens and desensitizes

GUM® SensiVital® + is a new solution that provides rapid and long-lasting alleviation of DH symptoms. This is achieved through an effective double effect: a combination of closing the dentinal tubules and desensitizing the nerve endings. The toothpaste closes the open canals with hydroxyapatite and seals them with an additional protective layer of copolymer. In addition, it strengthens the enamel and exposed dentin with a patented combination of fluoride and isomalt and desensitizes the nerve endings with potassium nitrate. Hesperidin (extract from organ peel) protects against root caries by stabilizing the collagen matrix of the dentin and reducing mineral loss. The mouthwash provides additional, long-lasting reduction in tooth sensitivity with potassium nitrate and a strengthening of the enamel and dentin with calcium glycerophosphate in conjunction with fluoride and isomalt. In a clinical study, the subjects who used the GUM® SensiVital® + toothpaste twice a day reported a significant improvement in their DH symptoms within 3 days 3 . In addition, according to the test subjects who used the mouthwash, the benefits lasted up to 12 hours after use.
