The most common reason behind poor dental health in mentally taxed patients is the behavioral effects of stress and anxiety. It can be difficult to have the discipline to follow a strict tooth care routine when battling a mental health condition, which is why it’s so important to take time out for self-reflection, which can give you the energy to put into everyday tasks. Depressed people are also more likely to have unhealthy diets and skip visits to the dentist.

Stress can also have physiological effects on the body. Spikes in the stress hormone cortisol weaken the immune system, which makes it easier for bacteria to invade the gums and cause inflammation. Certain antidepressants and anti-anxiety medications can cause dry mouth, which means that saliva isn’t available to clear away food debris after eating.

Those with severe anxiety sometimes exhibit symptoms such as canker sores and teeth grinding. Both of these are detrimental to oral health, with both short-term and long-term effects. In the case of teeth grinding, patients may permanently wear down essential molars and cause irreparable damage to protective enamel.
