If you are a mouth breather, it can have negative impacts on your dental health such as risk of decay and periodontal disease, the pathological inflammation of the gum and bone support surrounding the teeth. Mouth breathing leads to dry mouth and decreases the production of saliva. Saliva is important to regulate your mouth bacteria and neutralize acids.
In 2016, a study showed that individuals who are a mouth breather while they sleep experience higher acidity levels than those who do not.
This study measured ten healthy volunteers who slept with a nose clip to force them to breathe through their mouths. They slept with a device that measured the pH and temperature of their mouth. The volunteers wore this device to sleep for two sets of 48 hours. In addition, they wore the nose clip on two nights and without it for two nights to prevent any natural bias from affecting the study.
Mouth Breathing & Teeth: The Results
PH measures acidity, with pH 7 being neutral, under 7 is acidic, and above 7 is basic. An acidity level of pH 5.5 is the threshold in which tooth enamel begins to break down.
The results showed that a daytime mouth pH was 7.3 and during sleep it was 7.0. The mean pH during sleep with mouth breathing was 6.6. At some points during the night, mouth-breathing individuals had mouth pH levels of 3.6, which is far below the level in which tooth enamel breaks down.
The significance of the results shows that breathing through your mouth is detrimental to your overall oral health, but specifically tooth enamel through acid breakdown.
