If you are addicted to drugs, its high time you call it a quit as a research has found that doing drugs can also cause tooth decay. The findings, led by Hooman Baghaie from the University of Queensland in Australia, showed that drug use affects oral health through direct physiological routes such as dry mouth, an increased urge for snacking, clenching and grinding of teeth and chemical erosion from applying cocaine to teeth and gums. The lifestyle that often accompanies problematic drug use also affects oral health through high sugar diets, malnutrition, poor oral hygiene, and lack of regular professional dental care.Patients with substance use disorders also exhibited greater tooth loss, non-carious tooth loss and destructive periodontal disease. In addition, tolerance to pain killers and anaesthetics also contributes to poor dental care, the researchers said, in the paper published in the journal Addiction. Oral health has significant consequences on quality of life and general health. In addition to functional and self-esteem issues that accompany bad teeth, the chronic inflammation and bacteraemia (bacteria in the blood) characteristic of poor oral health increases the incidence of coronary heart disease, stroke, diabetes and respiratory disease. Researchers suggested that doctors and clinicians should screen people with substance use disorders for oral diseases and arrange for dental care as needed.
