Numerous studies have shown unsuspected links between oral health and general health. Knowing this, it is essential to adopt a rigorous oral hygiene and consult the dentist at least once a year. Even if everything is fine: the vast majority of gum inflammation and periodontal disease sets in without painful signs.
Sinusitis? Maybe because of a cavity
Most often, sinusitis is caused by an upper airway infection, but not always. The dental roots of the upper jaw are very close to the sinuses. “Hence the possibility that an infection such as a cavityspreads to the sinus and inflames it in turn,” says Dr. Francis Mora, periodontist-implantologist and expert from the French Dental Association.
Pathogenic bacteria from the mouth can also colonize the lungs. It is therefore recommended, in case ofpulmonary infectionto carry out an examination of the oral cavity.
Teeth and back pain, a possible link
At the origin of some back pain or neck pain, there is sometimes a dental malocclusion: poor positioning between the upper and lower teeth.
Dr. Mora: This imbalance can generate tension in the entire muscular chain of the back.
Conversely, a stature problem, for example a leg slightly longer than the other, can, when there is muscular fragility, sound up to the jaws and induce dental pain. The care will combine osteopathy sessions and wearing a gutter made by the dentist.
Periodontitis and diabetes, a dangerous link
“The relationship between diabetes and periodontal disease is established: hyperglycemia promotes the multiplication of oral bacteria and molecules modifying the inflammatory response. And it weakens the body’s defense cells,” explains the specialist. Unbalanced diabetes can thus weaken the supporting tissues of the tooth and expose them to a greater risk of periodontitis.
Conversely, untreated periodontal disease can, by generating inflammatory molecules, increase insulin resistance: blood sugar is then more difficult to control, and the risk of vascular complications is increased.
Take care of your teeth to protect your heart
Several works suggest a relationship between high blood pressurecardiovascular risk factor, and periodontitis : one would aggravate the other. Furthermore, “a bacterial attack could be involved, alongside other risk factors, in the mechanisms of atherosclerosis. »
The presence of Porphyromonas gingivalis, the bacterium involved in periodontal disease, has been found in the atherosclerotic plaque of patients who have developed a heart attack. “This does not mean that she is solely responsible for the coronary accident, but a study of nearly 10,000 people showed that the risk of infarction was increased by 25% in men suffering from periodontitis”, says Dr. Mora.
Bleeding caused by gingivitis and periodontitis – caused by poor oral hygiene – can indeed pass bacteria into the bloodstream, which can cause cardiovascular disease or a stroke.
Pregnant, better watch your teeth
An American study revealed it in 1996: pregnant women with periodontitis are 7.5 times more likely to give birth prematurely or give birth to a low-weight baby. Especially since because of pregnancy hormones, pregnant women are more at risk of developing this kind of dental pathologies, especially from the 3rd month.
« One of the hypotheses evokes the migration of bacteria which cause periodontitis in the vaginal flora through the blood circulation. »says Dr. Mora.
Hence the interest for those who have a baby project to consult their dentist: “Treating periodontitis before pregnancy reduces the risk of premature delivery by 60%”concludes Dr. Mora.
