If your hands bled upon washing them, you would probably be concerned. And yet, many people think it's normal for their gums to bleed when they brush or floss. In a 1999 study, researchers at the U.S. National Institutes of Health (NIH) found that half of Americans aged over 30 had bleeding gums. Swollen and bleeding gums could be a sign of gum problems. Without treatment, the gum problem could spread. It could affect the structures that support the teeth in your jawbone. Eventually, your teeth could become so loose that they have to be extracted.
"Peri" means around, and "odontal" refers to teeth. Periodontal problems affect the structures around the teeth. These include the gums, the cementum that covers the root, the periodontal ligament, and the alveolar bone. In the earliest stage of periodontal problems, only the gums are affected. In more severe forms, all of the supporting tissues are involved. For many years, scientists have been trying to figure out what causes periodontal problems. It is now well accepted that the germs found in dental plaque are the major villains. Researchers are also learning more about the effects of gum problems on overall health.
In recent years, gum problems have been linked to other health problems. This is a new and exciting area of research, but many questions remain. Studies have produced varying answers on the connection between gum problems and other medical problems. More extensive research is necessary.
Periodontal problems are caused by the germs found in dental plaque. Plaque is the sticky substance that forms on your teeth soon after brushing. In an effort to get rid of these germs, the cells of your immune system release substances that inflame and damage the gums, periodontal ligament or alveolar bone. This leads to swollen, irritated gums, which is a sign of the early stage of gum problems. Damage from periodontal problems can also cause teeth to become loose. This is a sign of severe periodontitis (the advanced stage of gum problems).
You can prevent periodontal problems by practising good oral hygiene and visiting your dentist regularly. You should see the dentist once every six months. However, if you already have gum problems, you may need to visit more often. When performed correctly, daily brushing and flossing can help remove most of the plaque from your teeth. Professional cleaning by your dentist or dental hygienist will keep plaque under control in places that are harder for a toothbrush or floss to reach.
If you slip up your oral hygiene or skip dental visits, plaque can build up on your teeth. Eventually, it will spread below the gum line. The germs are protected there because your toothbrush can't reach them. If the plaque is not removed, the germs will continue to multiply. Your gum problems may get worse.
The build-up of plaque below the gumline causes the gums to become inflamed. As the gums swell, they detach from the teeth. This process forms a space, or "pocket", between the tooth and gum. Germs can grow rapidly in the pockets. This encourages further plaque build-up. If left untreated, periodontal problems could destroy the periodontal ligament and the alveolar bone – the structures supporting your teeth.
Another reason to remove plaque promptly is that it becomes hardened or calcified over time and turns into calculus. This is commonly called tartar. As calculus has a rougher surface than tooth enamel, it leads to even more plaque accumulation. It is also rougher than cementum, a layer that covers the tooth root. Calculus and plaque build up in layers.
Consult your dentist for information on options that can help reduce and slow down the build-up of calculus.
The germs in plaque are the main cause of periodontal problems. However, several other factors, including but not limited to oral habits and medications, can contribute to gum problems. The following factors can increase and aggravate already existing gum problems:
