Many expectant mothers don't realize that gum inflammation doesn't just affect teeth and gums, but can also impact pregnancy. Studies show that periodontitis can be linked to premature births and low birth weight. This article explains why this is the case – and how you can protect yourself and your baby.
Periodontitis is a chronic inflammation of the gums caused by a disrupted biofilm – a layer of bacteria on the teeth. Pathogenic mechanisms of bacteria such as Porphyromonas gingivalis cause inflammation and can attack the gums and jawbone. If left untreated, this not only leads to bleeding gums and tooth loss, but also affects your overall health.
When you're pregnant, your hormone levels change. Your gums become more sensitive, more prone to inflammation, and bleed more easily – dentists call this pregnancy gingivitis. If left untreated, it can develop into periodontitis.
Why is this problematic? Inflammatory messengers and bacteria can reach the placenta via the bloodstream. Research shows that this can be associated with an increased risk of premature birth and lower birth weight.
Researchers discovered that bacteria such as P. gingivalis release inflammatory molecules (for example, prostaglandins). These can trigger labor in the body—far too early. According to a study by Offenbacher et al. (1996), women with severe periodontitis had up to a seven times higher risk of premature birth.
Important: Periodontitis doesn't just affect the mouth – it can have systemic consequences. This is precisely where PerioTrap's research comes in: The patented PerioTrap® technology specifically blocks the harmful properties of certain bacteria without destroying the beneficial ones in the mouth.
Approximately every second pregnant woman develops gingivitis – but few know that this can increase the risk of premature birth.
