Oral hygiene is the practice of keeping the mouth and teeth clean to prevent dental problems, most commonly, dental cavities, gingivitis, and bad breath. There are also oral pathologic conditions in which good oral hygiene is required for healing and regeneration of the oral tissues. These conditions included gingivitis, periodontitis, and dental trauma, such as subluxation, oral cysts, and following wisdom tooth extraction.
Chewing gum is a soft, cohesive substance intended for chewing but not swallowing. Humans have used chewing gum for at least 5,000 years. Modern chewing gum was originally made of chicle, a natural latex. By the 1960s, chicle was replaced by butadiene-based synthetic rubber which is cheaper to manufacture. Most chewing gums are considered polymers.
Teeth cleaning is part of oral hygiene and involves the removal of dental plaque from teeth with the intention of preventing cavities (dental caries), gingivitis, and periodontal disease. People routinely clean their own teeth by brushing and interdental cleaning, and dental hygienists can remove hardened deposits (tartar) not removed by routine cleaning. Those with dentures and natural teeth may supplement their cleaning with a denture cleaner.
A registered dental hygienist (RDH) is a licensed dental professional who specializes in preventive oral health, typically focusing on techniques in oral hygiene. Dental hygienists provide three types of services to their patients. The first of these is preventive services to promote and maintain good oral health. The second is educational services to help patients develop behaviours that promote better oral heath and help them understand the importance of practicing these behaviours. The third type of service provided is therapeutic services which are treatments meant to stop disease and maintain healthy tissues in the mouth. Local dental regulations determine the scope of practice of dental hygienists. In most jurisdictions, hygienists work for a dentist, and some are licensed to administer local anesthesia. Common procedures performed by hygienists include cleanings known as prophylaxis, scaling and root planing for patients with periodontal disease, taking of prescribed radio graphs, dental sealants, administration of fluoride, and providing instructions for proper oral hygiene and care.
Dental hygienist work together with dentist to contribute to a co-therapist environment, while providing optimum oral health care to the public. Dental hygienists also offer expertise in their field and provide the dental hygiene diagnosis, which is an integral component of the comprehensive dental diagnosis.
Dental diseases may affect the teeth, the gums, or other tissues and parts of the mouth. Dental diseases can cause much more serious problems than a toothache; they can affect our ability to chew, smile, or speak properly. Their severity may range from a simple aphthous ulcer or a common tooth cavity, to oral cancer.
These are among the most common diseases in humans and include dental caries, gingivitis, periodontitis and many more oral conditions. The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such as oral medicine, oral and maxillofacial surgery, and endodontics.
