Oral health and mental wellbeing are two aspects of our overall health that are often overlooked or considered separately. However, research has shown that there is a strong connection between the two, with poor oral health having a negative impact on mental wellbeing, and vice versa. Understanding this connection is crucial for maintaining good overall health and improving our quality of life. In this article, we will explore the various ways in which oral health and mental wellbeing are interconnected, and how taking care of one can positively affect the other.

The Oral-Systemic Connection

Our mouth is not an isolated part of our body; it is connected to the rest of our body through various systems. The oral-systemic connection refers to the relationship between oral health and overall health, particularly the impact that oral health can have on systemic conditions such as cardiovascular disease, diabetes, and respiratory infections.

Research has shown that poor oral health, such as gum disease, can contribute to the development or worsening of these systemic conditions. For example, gum disease has been linked to an increased risk of heart disease and stroke. The bacteria present in the mouth can enter the bloodstream and cause inflammation in the arteries, leading to the formation of plaques and increasing the risk of cardiovascular events.

Furthermore, individuals with diabetes are more prone to gum disease, and gum disease can make it more difficult to control blood sugar levels. This bidirectional relationship between oral health and systemic conditions highlights the importance of maintaining good oral health for overall wellbeing.

The Impact of Oral Health on Mental Wellbeing

While the oral-systemic connection is well-established, the link between oral health and mental wellbeing is a relatively new area of research. However, emerging evidence suggests that there is a significant association between the two.

1. Psychological Impact: Poor oral health can have a negative psychological impact on individuals. Dental problems such as tooth loss, bad breath, and discolored teeth can lead to low self-esteem, social anxiety, and even depression. Individuals may feel self-conscious about their smile and avoid social situations, leading to isolation and a decline in mental wellbeing.

2. Pain and Discomfort: Oral health issues such as tooth decay, gum disease, and oral infections can cause significant pain and discomfort. Chronic pain can have a profound impact on mental health, leading to increased stress, anxiety, and depression. The constant presence of pain can also disrupt sleep patterns, further exacerbating mental health issues.

3. Cognitive Function: Research has shown that poor oral health, particularly gum disease, may be associated with cognitive decline and an increased risk of developing conditions such as Alzheimer’s disease. The inflammation caused by gum disease can affect brain function and contribute to cognitive impairment.

4. Eating Disorders: Oral health problems are often prevalent in individuals with eating disorders such as bulimia nervosa and anorexia nervosa. Frequent vomiting in bulimia can lead to erosion of tooth enamel, while malnutrition in anorexia can result in weakened teeth and gums. These oral health issues can further contribute to the mental and physical health challenges faced by individuals with eating disorders.

The Influence of Mental Wellbeing on Oral Health

While poor oral health can negatively impact mental wellbeing, the reverse is also true. Mental health conditions can have a significant influence on oral health, leading to neglect of oral hygiene and an increased risk of dental problems.

1. Neglect of Oral Hygiene: Individuals experiencing mental health conditions such as depression, anxiety, or schizophrenia may struggle with daily activities, including maintaining proper oral hygiene. Brushing and flossing regularly may become challenging due to lack of motivation, fatigue, or cognitive difficulties. This neglect can result in the development of dental issues such as cavities, gum disease, and bad breath.

2. Medication Side Effects: Many medications used to treat mental health conditions can have adverse effects on oral health. For example, antidepressants and antipsychotics can cause dry mouth, which increases the risk of tooth decay and gum disease. Additionally, some medications may cause bruxism (teeth grinding) or clenching, leading to tooth damage and jaw pain.

3. Substance Abuse: Substance abuse is often associated with poor oral health. Individuals who abuse drugs or alcohol may neglect their oral hygiene, have a higher risk of tooth decay and gum disease, and experience oral health issues such as oral infections and tooth loss. Substance abuse can also lead to nutritional deficiencies, which can further impact oral health.

Improving Oral Health and Mental Wellbeing

Given the strong connection between oral health and mental wellbeing, it is essential to prioritize both aspects of our health. Here are some strategies to improve oral health and promote mental wellbeing:

  • Practice good oral hygiene: Brush your teeth at least twice a day, floss daily, and visit your dentist regularly for check-ups and cleanings.
  • Manage stress: Stress can contribute to poor oral health and mental wellbeing. Find healthy ways to manage stress, such as exercise, meditation, or engaging in hobbies.
  • Seek professional help: If you are struggling with mental health issues, seek support from a mental health professional. They can provide guidance and treatment options to improve your mental wellbeing.
  • Address substance abuse: If you are struggling with substance abuse, seek help from a healthcare professional or addiction specialist. They can provide resources and support to overcome addiction and improve your oral health and overall wellbeing.
  • Eat a balanced diet: A nutritious diet is essential for both oral health and mental wellbeing. Limit sugary and acidic foods and drinks, and opt for a diet rich in fruits, vegetables, whole grains, and lean proteins.


Oral health and mental wellbeing are intricately connected, with each influencing the other. Poor oral health can have a negative impact on mental wellbeing, leading to low self-esteem, pain, and cognitive decline. Conversely, mental health conditions can contribute to neglect of oral hygiene and an increased risk of dental problems. By prioritizing both aspects of our health and seeking appropriate care, we can improve our overall wellbeing and enjoy a healthier, happier life.
