Do Crooked Teeth Get Worse With Age?

Crooked teeth, also known as malocclusion, refer to any misalignment of the teeth or jaws. The answer to whether crooked teeth worsen with age is yes; these dental misalignments can indeed progress over time, affecting both the appearance and function of the mouth.

The Reality of Age-Related Dental Shifts

Teeth are not static structures; they undergo continuous, subtle movements throughout an individual’s life. These natural, slow shifts often go unnoticed for years. One such natural phenomenon is “mesial drift,” which describes the inherent tendency of teeth to gradually move forward towards the front of the dental arch. This movement helps maintain contact between adjacent teeth, compensating for natural wear that occurs from chewing. The oral environment is dynamic, constantly responding to various forces and changes, including the subtle pressures from lips, tongue, and cheeks, as well as the daily impacts of biting and chewing. Over decades, these consistent, low-level forces can accumulate, leading to noticeable changes in tooth position.

Key Factors Driving Worsening Misalignment

Several factors contribute to the progressive worsening of crooked teeth over time.

Changes in bone density and jaw structure

As individuals age, the jawbone can experience a decrease in density and volume. This reduction in bone support can make teeth less securely anchored, increasing their susceptibility to shifting out of alignment. The lower jaw, in particular, may exhibit changes in its angle and position, potentially leading to increased crowding of the lower front teeth.

Tooth wear and loss

Over years of chewing, teeth naturally experience wear on their biting surfaces, which can create small gaps. The loss of a tooth creates an open space, prompting adjacent teeth to drift or tilt into the void, disrupting the overall alignment of the dental arch. This movement can lead to new misalignments and bite issues.

Gum disease, or periodontal disease

Gum disease, or periodontal disease, affects the tissues supporting the teeth, leading to the deterioration of the jawbone and ligaments that hold teeth in place. As the supporting structures weaken, teeth can become loose and shift, often resulting in increased spacing or crowding. If left untreated, the infection can advance, causing significant bone loss.

Oral habits and forces

Oral habits and forces also exert continuous pressure on teeth, influencing their position. Chronic clenching or grinding of teeth (bruxism) places tremendous stress on the teeth and their supporting structures, which can cause teeth to shift over time. Habits such as tongue thrusting, where the tongue pushes against the front teeth during swallowing, or even consistent pressure from the lips or cheeks, can also contribute to dental misalignment.

Previous dental work

Previous dental work can sometimes play a role in later misalignment. Dental restorations that are no longer properly fitted or aligned with the bite can introduce uneven forces, potentially causing other teeth to shift. For individuals who have undergone orthodontic treatment, neglecting to wear prescribed retainers can lead to a relapse, where teeth gradually shift back towards their original, misaligned positions.

Consequences of Progressive Dental Changes

The progressive worsening of crooked teeth can lead to a range of oral health problems and functional issues beyond aesthetic concerns.

Misaligned teeth create areas that are difficult to clean effectively

Misaligned teeth create areas that are difficult to clean effectively, increasing the risk of oral health issues. Crowded or overlapping teeth provide crevices where food particles and plaque can accumulate, making proper brushing and flossing challenging. This persistent buildup can lead to a higher incidence of cavities and gum disease.

A misaligned bite can also result in chewing and speech difficulties

When teeth do not fit together correctly, the efficiency of chewing can be compromised. In some cases, significant misalignment can affect speech articulation.

Jaw pain and temporomandibular joint (TMJ) issues

An improper bite can place undue stress on the temporomandibular joints. This can lead to symptoms such as jaw pain, headaches, clicking or popping sounds in the jaw, and even limited jaw movement.

Uneven tooth wear

Uneven tooth wear is another problem arising from misaligned teeth. When the bite is not properly aligned, certain teeth may bear disproportionate amounts of force during chewing. This uneven distribution of pressure can lead to accelerated wear of the tooth enamel, potentially causing sensitivity, chipping, or even fractures over time.

Beyond the physical effects, aesthetic concerns and self-confidence

Beyond the physical effects, aesthetic concerns and self-confidence can be impacted by worsening misalignment. The visual changes in a person’s smile due to increasingly crooked teeth can affect their self-perception and willingness to smile freely.

Proactive Steps for Maintaining Alignment

Maintaining proper tooth alignment as one ages involves a combination of consistent oral care and professional oversight.

Regular dental check-ups and cleanings

Regular dental check-ups and cleanings are fundamental for monitoring oral health and detecting early signs of misalignment. These professional visits allow dentists to assess the condition of teeth and gums, identifying potential issues before they become more significant. Early intervention can often prevent minor shifts from progressing into more complex problems.

Addressing oral habits

Addressing oral habits is also important. For individuals who clench or grind their teeth, managing bruxism, often with a custom-fitted nightguard, can protect teeth from excessive wear and reduce forces that contribute to shifting. Other habits, such as chronic nail-biting or tongue thrusting, can also be identified and managed to reduce their impact on tooth alignment.

For those who have undergone orthodontic treatment, consistent use of retainers

For those who have undergone orthodontic treatment, consistent use of retainers is essential for maintaining alignment. Wearing retainers as prescribed, often for a lifetime, stabilizes the teeth in their corrected positions while the surrounding bone and tissues adapt.

Considering an orthodontic consultation

Considering an orthodontic consultation is advisable if significant shifting or new alignment problems arise. Orthodontic treatment, including braces or clear aligners, can be effective at any age, provided the teeth and gums are healthy. An orthodontist can assess the specific situation and recommend appropriate interventions to correct misalignment and improve long-term oral health.

Good oral hygiene practices

Good oral hygiene practices, including daily brushing and flossing, are foundational. These practices help prevent gum disease, which is a major cause of tooth movement and loss of support. Maintaining healthy gums and surrounding bone structures provides a stable foundation for teeth.
