Mouth to sleep not only cause dry mouth, but also a threat to oral health. New United states University of NY study found that prolonged mouth breathing, such as mouth to sleep, the mouth is more likely to be corroded, tooth decay risk will rise.
The researchers selected 10 healthy volunteers who asked them to wear an oral appliance to measure the pH in the saliva. PH value can reflect the water-based solution (such as saliva) pH, usually, saliva normal PH value range of 6.6 to 7.1.
During the four-day trial period, the investigators asked participants to wear nose clips to stimulate their mouths to breathe. The results showed that people who were forced to breathe their mouths had a PH value of 6.6 for saliva and was acidic. When the participants were forced to breathe at night with their mouths, the pH of their saliva in the mouth dropped significantly to 3.6.
The university researcher, Dr. Joan, points out that the PH value in the oral cavity drops in the normal sleep state, but the mouth breathing causes the value to drop more. In addition, when the PH value drops below 5.5, the teeth began to lose minerals, resulting in less protection of the teeth, in addition, mouth breathing so that the rapid evaporation of saliva, resulting in reduced protective effect on the teeth, increase the risk of tooth decay The In addition, bacteria that produce acidic substances can thrive in the absence of saliva. Acid foods break down the teeth, cause tooth decay, and stimulate the soft tissue in the mouth. As the amount of saliva produced at night will be reduced, so people who breathe more easily feel dry mouth, tooth decay and the risk of inflammation of the gums will increase.
Experts remind that people should beware of the performance of tooth decay, such as excessive tooth sensitivity, bad breath, faded spots on the teeth and oral odor, once found to be timely treatment, or tooth decay can cause more serious oral problems, such as tooth abscess and gum disease.
Leading to long-term breathing with the reasons for nasal congestion, sleep disorders and personal physiological and structural differences, etc., timely response to these conditions, not only contribute to the health of the respiratory system, but also vital to dental health. In addition, we should pay attention to oral hygiene clean, every day with fluoride toothpaste to brush your teeth twice, every 3 minutes, every day with at least floss to clean the teeth once, these are necessary for the prevention of tooth decay.
