“…excellent medical device…”

I have been treating patients with dry mouth for many years. The SaliPen is an excellent medical device to stimulate salivary flow.  As such, I am now prescribing it to my patients that suffer from dry mouth.

The SaliPen is especially valuable for the patient who cannot tolerate salivary stimulant medication. Nevertheless, it can be used alone or as an adjunct to salivary stimulant medication or to local agents like mouthwashes, lozenges, gels, etc.

“…massive impact on patients’ quality of life…”

“The SaliPen sends out little electric impulses through to the salivary glands, triggering them to produce saliva. It’s so subtle you can’t feel it.
It has a massive impact on patients’ quality of life.”

Scientific articles about the SaliPen® device

The following articles researched how Saliwell® devices successfully treat dry mouth by electrostimulation

Alajbeg I et al. Intraoral electrostimulator for xerostomia relief – a long-term multicenter open-label uncontrolled clinical trial. Oral Surg Oral Med Oral Pathol Oral Radiol, 2012;113:773-781.

Objective. A previous sham-controlled multinational study demonstrated the short-term efficacy and safety for xerostomia treatment of an intraoral device that delivers electrostimulation to the lingual nerve. The objective of this study was to test the hypothesis that those beneficial effects would be sustained over an 11-month period.

Study Design.
The device was tested on a mixed sample of 94 patients with xerostomia in an open-label, uncontrolled, prospective multicenter trial. Statutory outcome assessments were done at 5th, 8th, and 11th months and analyzed by multiple comparisons.
Results. Improvements achieved at month 5 from baseline were sustained throughout the follow-up period for the primary outcome, xerostomia severity, and the secondary outcomes resting whole salivary flow rate, xerostomia frequency, oral discomfort, and difficulties in speech, swallowing, and sleeping. No significant side effects were detected.

The beneficial effects of a removable intraoral electrostimulating device was proved, and grows steadily with consistent use.

Strietzel FP et al. Efficacy and Safety of an Intraoral Electrostimulation Device for Xerostomia Relief: A Multicenter Randomized Trial. Arthritis & Rheumatism, 2011;63:180–190.


Objective: To evaluate the efficacy and safety of an intraoral electrostimulation device, consisting of stimulating electrodes, an electronic circuit, and a power source, in treating xerostomia. The device delivers electrostimulation through the oral mucosa to the lingual nerve in order to enhance the salivary reflex. Methods. The device was tested on a sample of patients with xerostomia due to Sjögren’s syndrome and other sicca conditions in a 2-stage prospective, randomized, multicenter trial. Stage I was a double-blind, crossover stage designed to compare the effects of the electrically active device with the sham device, each used for 1 month, and stage II was a 3-month open-label stage designed to assess the long-term effects of the active device. Improvement in xerostomia severity from baseline was the primary outcome measure.

Results: A total of 114 patients were randomized. In stage I, the active device performed better than the sham device for patient-reported xerostomia severity (P < 0.002), xerostomia frequency (P < 0.05), quality of life impairment (P < 0.01), and swallowing difficulty (P < 0.02). At the end of stage II, statistically significant improvements were verified for patient-reported xerostomia severity (P < 0.0001), xerostomia frequency (P < 0.0001), oral discomfort (P < 0.001), speech difficulty (P < 0.02), sleeping difficulty (P < 0.001), and resting salivary flow rate (P < 0.01).


Our findings indicate that daily use of the device increased salivary output, alleviated oral dryness, discomfort, and some complications of xerostomia, such as speech and sleeping difficulties.

The results show a cumulative positive effect of the device over the period of the study, from baseline to the end of the trial.

Strietzel FP et al. Electrostimulating device in the management of xerostomiaOral Diseases, 2007; 13: 206–213

Introduction: The present study was undertaken to evaluate the safety and effectiveness of a recently developed electrostimulating device mounted on an individualized intra-oral removable appliance.

Materials and methods: The device, containing electrodes, a wetness sensor, an electronic circuit and a power source, was tested on patients with xerostomia in a crossover, randomized, sham-controlled, double-blinded, multicenter study. Electrical stimulation and also sham were delivered during 10 min to the oral mucosa, in the mandibular third molar region. Oral dryness was measured by the sensor. As the primary outcome, sensor dryness and xerostomia symptom changes as a result of device wearing were assessed, and compared between active and sham modes. In addition, side-effects were recorded.

Electrostimulation resulted in a significant decrease in oral dryness, leading to a beneficial effect on patients’ subjective condition. No significant side effects were observed.

Wolff A et al. Electrostimulation of the lingual nerve by an intraoral device may lead to salivary gland regeneration: A case series studyMed Oral Patol Oral Cir Bucal, 2018; 23(5): e552-e559

Salivary gland function is controlled by the salivary reflex, whose efferent arm is composed by the parasympathetic and the sympathetic divisions of the autonomic nervous system. Parenchymal injury is the main salivary gland involvement of Sjögren’s syndrome and head and neck radiotherapy, but neural damage has been reported as well. Recently an intraoral device for electrostimulation of the lingual nerve in vicinity to the lower third molar has been introduced. At this point this nerve carries efferent fibers for the innervation of the submandibular, sublingual and several minor salivary glands and afferent fibers of the salivary reflex. Therefore, excitation of these fibers potentially leads to increased secretion of all salivary glands. Thus, the study objective was to assess whether comprehensive neural activation by electrostimulation of the lingual nerve carries the potential to induce the regeneration of damaged salivary glands.

Materials and methods:
The device was tested on three patients with no collectable resting and stimulated secretion of saliva during a double blind, sham controlled period of two months and nine open-label months.


All three subjects developed the capacity to spit saliva, not only in direct response to the electrostimulation but also after many hours without electrostimulation.

In addition, their symptoms of dry mouth severity and frequency were improved.

Dr. Andy Wolff. Electrostimulator and xerostomia. Dentaltown website. Retrieved February 2019.

…at the end of the trial other subjective parameters such as oral discomfort, speech difficulty, frequency of waking at night and the rate of salivary flow (both unstimulated and stimulated by mastication) had improved.

“…clinical studies have shown that in patients without any salivary output lingual nerve stimulation led to regaining their ability to spit saliva…”

Zadik Y et al. Safety and efficacy of an intra-oral electrostimulator for the relief of dry mouth in patients with chronic graft versus host disease: Case Series. Med Oral Patol Oral Cir Bucal, 2013 Oct 13.

Objectives: Patients with chronic graft-versus-host disease (cGVHD) often suffer from dry mouth and oral mucosal lesions. The primary objective of this study was to investigate the safety of an intra-oral electrostimulator (GenNarino*) in symptomatic cGVHD patients. The secondary objective was to study the impact on the salivary gland involvement of cGVHD patients. Study Design: This paper presents a case series. The study included patients treated for 4 weeks, randomly assigned to the active device and then crossed-over to a sham-device or vice versa. The patients and clinicians were blind to the treatment delivered. Data regarding oral mucosal and salivary gland involvement were collected. 

…the use of GenNarino* resulted in subjective and objective improvements in dry mouth symptoms.

*GenNarino is an earlier generation device utilizing similar technologies as SaliPen does.
