Periodontics is a dental specialty that involves prevention, diagnosis, and treatment of the bone and gum tissue surrounding your teeth.
Gum disease is very common – it affects more than half of adults with natural teeth. It can be treated by a dentist or hygienist and in the early stages the effects can be reversed.
There are three main types of gum disease: gingivitis, periodontitis and acute necrotising ulcerative gingivitis. If you have gingivitis, your gums become irritated by plaque, which is a mixture of food, bacteria and bacterial waste products that can build up on your teeth.
If you don’t clean plaque off your teeth regularly, your gums will become red, swollen and shiny, and they may bleed. This is the early stage of gum disease and is completely reversible. If you remove the plaque, your gums will recover. But if you don’t clean the plaque off your teeth, the gingivitis may develop into periodontitis.
If you don’t get treatment for gingivitis, your gums may begin to pull away from your teeth, leaving small pockets. These pockets trap plaque that you can’t reach with a toothbrush. Over time, the plaque will harden to become tartar (calculus).
Plaque and tartar build-up can cause further irritation, which may gradually spread to the bone structures around your teeth. As time goes on, the pockets can get deeper and more difficult to clean, and your gum and bone may shrink. This is called periodontitis.
If your gums shrink, they can expose some of the roots of your teeth, making them sensitive. And if you have bone loss, your teeth may become loose. If you don’t get treatment for a number of years, your teeth may fall out, or need to be taken out by a dentist.
It’s rarely possible to make the bone structures grow back, so periodontal pockets aren’t generally reversible. However, if you receive the appropriate treatment and make sure you floss and brush your teeth well, the progress of the disease can be stopped.
