Introduction

It is commonly known that a smile exudes confidence, kindness, happiness and warmth. But what happens if a fear of smiling is added to a list of other struggles? Have you ever heard of tooth agenesis? This article will tell you what tooth agenesis is, especially how it can impact someone psychologically and socially.

Tooth agenesis is defined as a congenital lack of teeth. Both sexes and continents have different rates of tooth agenesis. In general, females have 1.37 times the rate of tooth agenesis compared to males. The maxillary lateral incisor and maxillary second premolar were the next most afflicted teeth, after the mandibular second premolar.¹ Although this illness can easily draw attention, it's important to understand how it may impact a person's psychological and social well-being.

The psychological impact of tooth agenesis:

Some serious functional, cosmetic, and psychological issues are linked to tooth agenesis. Of special importance are the emotional and psychological impacts, which affect mental health, social interactions, and self-esteem in a variety of age groups.

Self-esteem and self-image

Missing teeth can cause significant emotional discomfort in children and adolescents alike. Children who have oligodontia, or the loss of several teeth, may be teased or bullied, which can exacerbate feelings of loneliness and low self-esteem.² Such negative social experiences are linked with lower levels of social competence, body image-related self-esteem, and general self-worth.³ Teenagers, who are especially self-conscious about how they look, may shy away from social situations or feel awkward when they smile, which lowers their social engagement and may raise their risk of anxiety and depression.

According to research, the practical and emotional damage increases with the number of missing teeth. For instance, when compared to a control group, a study on children with oligodontia revealed notable variations in oral symptoms, functional limits, and social and emotional well-being.³ These challenges go beyond appearances and include functional concerns like speech, chewing, and everyday social interactions.

Depression and emotional distress

Tooth agenesis carries an emotional cost that goes beyond anxiety and social discomfort. One's facial look can be significantly altered by the obvious lack of teeth, especially in the front of the mouth. People with missing teeth are susceptible to feelings of inadequacy, which can result in sadness and mental anguish in communities where having a complete set of teeth is frequently associated with beauty and health. People may internalise the ideals of beauty set by society, and feeling "less than" others can be made worse by not being able to live up to these standards. Chronic low self-esteem and, in more extreme situations, clinical depression can result from this psychological stress.

Social impact of tooth agenesis

Interpersonal relationships

People who have prominent gaps in their teeth may feel more anxious in social settings. Speaking, smiling, and eating are common social activities that might draw attention to missing teeth, particularly if they are in the front of the mouth. People may become ashamed or self-conscious as a result, causing them to completely avoid social situations. Some people may grow so wary of public speaking or socialising that they deliberately avoid these situations to hide their missing teeth from being criticised. This can intensify feelings of isolation and loneliness, especially since someone's perception of self-worth is based on how they believe other people judge their appearance.

Professional challenge

Beauty and social interaction are highly valued in fields like sales, fashion, and the media, which makes them especially difficult for people with missing teeth. How people are viewed in various professional contexts can be greatly impacted by the stigma associated with tooth gaps. Missing teeth may unjustly be interpreted by coworkers or employers as a sign of incompetence or poor personal hygiene, especially in positions requiring regular interaction with the public. This prejudice can worsen the psychological effects of tooth agenesis by impeding professional advancement, resulting in lost opportunities, and causing emotions of stress, frustration, and low self-esteem.⁵ 

Quality of life

According to research, the degree of challenges with everyday activities like eating and drinking, particularly in social situations, increases with the number of missing teeth. Social anxiety can be made worse by these functional difficulties because people may worry about being stigmatised or criticised for their perceived shortcomings. These fears frequently deter people from attending social events where eating is not only a need but also a meaningful way to connect.⁴ Consequently, this withdrawal from social activities can negatively impact an individual’s overall quality of life and emotional well-being.

Psychological and social challenges by gender and age group

Individuals of all ages and genders experience the psychological effects of tooth agenesis differently, with particular difficulties arising at every stage of life. Some variables, including self-esteem, cultural expectations, and the significance of dental aesthetics, can affect how severe and how these difficulties occur.

Gender

The psychological effects of tooth agenesis affect both individuals assigned female at birth (AFAB) and persons assigned male at birth (AMAB), although, in societies where individuals AFAB  are frequently evaluated based on their appearance, persons AFAB may feel more emotional discomfort because of cultural expectations that place a higher value on attractiveness and aesthetics.⁶ According to research, persons AFAB are more likely to voice worries about being unattractive and how it can affect their social and professional lives. It is crucial to remember that these gender disparities are not always present and can change depending on personal experiences, cultural background, and dental care accessibility.

Children

Missing teeth can have a big emotional impact on kids, mostly because of bullying and victimisation by peers. According to a study by Seehra et al., children who have obvious dental differences frequently endure ongoing bullying, which can result in social isolation and low self-esteem.⁴ Children who have lost teeth may also have trouble eating and speaking, which can further impair their emotional health and social interactions.⁷ As individuals mature, these early experiences may have a lasting impact on their sense of self and capacity to build healthy relationships.

Adolescent

Adolescence is a particularly delicate time for the formation of self-esteem, and identity is greatly influenced by one's physical appearance. Teenagers are frequently more self-conscious about their appearance, and having missing teeth can make them feel even more insecure. Social withdrawal, avoiding hanging out with peers, and a higher chance of developing anxiety or depression can all result from missing teeth.⁷ Social expectations about beauty and the idealised concept of a "perfect smile" can exacerbate these feelings of inadequacy, leading to a negative body image and a decline in self-confidence.

Adults

The psychological effects of tooth agenesis on adults go beyond issues of self-worth to include social and professional issues. People may have self-consciousness about how they look, which can impact their confidence in social and professional contexts. People who deal with the public regularly, such as those in leadership or customer service positions, could be concerned that their dental appearance will make them appear less capable or professional. Social withdrawal, trouble establishing romantic relationships, and trouble sustaining a positive self-image can result from this worry.⁶ In addition, chronic low self-esteem or even depression can be brought on by the pressure to live up to society's standards of beauty.⁸ 

Older adults

Even though they might be better able to adjust to the changes in their dental look, older persons may nonetheless be emotionally distressed by tooth agenesis. Some people may still experience functional limitations, including chewing difficulties and limited dietary options, which might affect their quality of life, even if they have learnt coping mechanisms over time.¹  The discontent resulting from these functional difficulties might impact interpersonal relationships and emotional health, particularly in settings where bonding is primarily facilitated by eating and socialising.

Management

The management of tooth agenesis involves a multidisciplinary team for the intervention. Tooth agenesis treatments include prosthetics, implants, and orthodontics, but psychological care is especially important. Orthodontic treatment appears to significantly impact a range of psychological and aesthetic scales.⁹ Missing teeth can impact self-esteem, particularly in children and adolescents. Counselling or therapy can help individuals build confidence and cope with appearance-related concerns, making psychological support a critical part of holistic care alongside dental solutions. Individuals with missing teeth could benefit from joining a support group with people having similar conditions.

Summary

Tooth agenesis goes beyond being a physical condition; it carries significant psychological consequences that affect individuals' self-perception, confidence, and mental well-being. Its impact is most profound during life stages where appearance and social acceptance are paramount, such as childhood and adolescence, but it continues to influence adults and older individuals in unique ways. These psychological challenges highlight the importance of comprehensive care that extends beyond functional restoration.

By integrating psychological support with dental treatments, healthcare professionals can not only address the visible effects of tooth agenesis but also nurture emotional resilience and self-esteem. Ultimately, tackling both the physical and psychological dimensions of tooth agenesis is essential for improving the overall quality of life for affected individuals and fostering a sense of well-being and inclusion in society.
