I think a very good example would be a person who is unable to access dental care for an immediate problem, such as a toothache. They have an infected tooth that either needs to have a root canal treatment or it needs to be taken out. If they're not able to get to a dentist and receive the care they need, they end up in the emergency ward of the local hospital. In that appointment, they're seen and assessed, but the definitive treatment is not rendered. There are very few hospitals that have dental departments in them. As a result, that person is given a prescription for an antibiotic, sort of on speculation, whether or not they actually need it, but they're given it just in case. Now we have the potential overuse of antibiotics, which has a whole lot of other implications for health. As well, they're given a prescription for, usually, very strong painkillers, such as an opioid.
The root of the problem has actually not been addressed. That visit to the health system costs the provincial health system anywhere from $500 to $700 and still they did not get the treatment that would have taken care of the problem, which in a dental office would probably have cost less than half of that. That would be a very direct example of an emergency situation.
I'm on staff at the University of Toronto faculty of dentistry. I teach in emergency and oral diagnosis, so we see people with an awful lot of chronic conditions—diabetes, cardiovascular diseases, rheumatoid arthritis and the inflammatory effects of gum disease—what we call periodontal disease—which is actually a disease of bone that has significant effects on the inflammatory processes in the human body, so there are lots of implications. Whatever happens in the mouth is either a sign of something happening in the body or the result of something happening in the body and/or the treatment of it.
