Tooth decay and cavities Archive

A 2023 study suggests that toothbrushing twice daily can lower rates of hospital-acquired pneumonia in seriously ill hospitalized patients.

Tooth, gum, or jaw pain can stem from many health problems. For example, tooth pain can result from a cavity, cracked filling, or an infection. Gum pain can come from irritation due to tooth brushing, food, dentures, gum disease, or infection. Jaw pain can be triggered by disorders of the temporomandibular joint, narrowed heart arteries, or even a heart attack. All persistent tooth, gum, and jaw pain should prompt a call to a dentist as soon as possible. Sudden neck or lower jaw pain can signal an emergency and warrants a call to 911, especially in a person with known heart problems.

A 2023 study found that patients in intensive care units (ICUs) were less likely to die and spent less time on a ventilator during their stay when their teeth were brushed twice daily. Toothbrushing appears to protect patients from pneumonia, the most common ICU-acquired infection.

New research suggests that people who are hospitalized in an intensive care unit are far less likely to develop pneumonia if their teeth are brushed twice daily. They also need ventilators for less time, are able to leave the ICU more quickly, and are less likely to die in the ICU.

Certain healthy habits can fight chronic inflammation, such as eating a healthy diet, exercising regularly, getting enough sleep, maintaining good oral health, and reducing stress. If adopting all those habits seems daunting, taking little steps in their direction can help. For example, a person might eat fatty fish twice a week, since it contains omega-3 fatty acids known to reduce inflammation; or go for a quick daily walk, since exercise may increase the production of hormones that help keep inflammation in check. The combined effects of many little habits can eventually add up to keep people healthier.
