As Occupational Health Consultants, our primary aim is to help ensure the health and safety of workers and their families. 1. Smoking is not only damaging to your body but also has serious dental and periodontal effects. We offer people guidance in ways in which to quit smoking. We explain to such people how they can rid themselves of nicotine stains and bad breath, and quit smoking by using the pocket tooth brush. 2. We manufacture sleep splints that have proven beneficial for people who snore or suffer from sleep apnea and have contributed to reductions in the occurrence of traffic and work-related accidents. 3. We produce mouth guards to increase sporting ability and ensure safety in contact sports. People who suffer from temporomandibular conditions are more likely to suffer from uncertain balance making them more susceptible to falls. We teach such people ways in which they can counter this.
