How Long Does it Take for Braces to Straighten Teeth?

Having braces can be an effective way to achieve a beautiful smile, but it also requires extra attention to oral hygiene. Proper care and maintenance are essential to ensure the health of your teeth and gums throughout the orthodontic treatment. 

In this article, we will provide you with valuable tips for maintaining oral hygiene with braces, helping you navigate this exciting journey while keeping your smile bright and healthy.

Factors Influencing Teeth Straightening Duration

a. Severity of Dental Misalignment

1. Mild Cases: Spacing or Slight Crowding

Treatment Overview: Mild misalignment often requires less time to correct, as the amount of movement required for each tooth is relatively minimal.

Average Duration: The treatment time for mild cases can be shorter, often ranging from a few months to a year or two.

2. Moderate Cases: Overbites, Underbites, and Crossbites

Treatment Overview: These bite discrepancies often involve a more complex shifting of the teeth and jaw, necessitating a longer and more involved treatment.

Average Duration: Depending on the specific nature of the misalignment, treatment can take anywhere from 1 to 3 years.

3. Severe Cases: Rotated teeth, Impacted teeth, and Significant Misalignments

Treatment Overview: Severe dental issues often require a combination of orthodontic devices, potential tooth extractions, and, in some instances, surgical procedures to rectify.

Average Duration: Severe cases often take multiple years to treat, with some complex cases lasting 3-5 years.

b. Age and Bone Density

Children vs. Adults: Speed of Treatment

Children: Their jaws and bones are still growing, which can make teeth movement faster and often more responsive to orthodontic treatment.

Adults: Adult bones are denser and no longer growing, which can extend the treatment duration.

How Does Bone Density Affect the Movement of Teeth?

The denser the bone, the slower and more challenging it can be to shift teeth. Conversely, less dense bone allows for quicker movement, but may also present risks of instability.

c. Type of Treatment Selected

1. Traditional Braces

Treatment Overview: Utilize brackets and wires to apply pressure and move teeth.

Average Duration: Typically, 18 months to 3 years, depending on the case’s severity.

2. Clear Aligners (e.g., Invisalign)

Treatment Overview: Custom-made, clear plastic aligners are changed every couple of weeks to progressively shift teeth.

Average Duration: Generally, 6 months to 2 years, although it can vary based on individual needs.

3. Lingual Braces

Treatment Overview: Similar to traditional braces but placed on the inside (lingual side) of teeth.

Average Duration: Can range from 18 months to 3 years, comparable to traditional braces.

4. Palatal Expanders

Treatment Overview: Used mainly in children and teens to widen the upper jaw, creating more space for teeth.

Average Duration: Typically worn for several months up to a year, depending on the expansion required.

d. Patient Compliance

Importance of Following Orthodontist’s Guidelines

Successful treatment largely hinges on the patient’s commitment to the prescribed treatment plan. Non-compliance can extend treatment duration significantly.

Regular Appointments and Adjustments

Consistently attending scheduled appointments ensures that the treatment progresses as planned. Missing or delaying appointments can hinder progress.

Wearing Devices as Recommended, e.g., Elastics, Retainers

Additional orthodontic devices often play crucial roles in treatment. Not using them as instructed can slow down treatment and compromise results.

Potential Setbacks and Delays in Teeth Straightening

1. Injuries or Breakages:

Potential Impact: Damage to orthodontic devices, such as broken braces or wires, can halt or even reverse progress. Immediate attention is necessary to prevent complications.

Prevention: Avoiding hard or sticky foods, wearing mouthguards during sports, and maintaining proper oral hygiene can reduce the risk of breakages.

Solution: Regular dental check-ups and prompt repairs if any breakage occurs.

2. Missing Appointments:

Potential Impact: Regular adjustments are vital for the progress of teeth straightening. Missed appointments can prolong treatment time.

Prevention: Schedule reminders and prioritize orthodontic visits.

Solution: Reschedule missed appointments as soon as possible.

3. Not Following Orthodontist’s Guidelines:

Potential Impact: Non-compliance with treatment instructions, like not wearing aligners for the required hours or neglecting to use elastics, can delay or even reverse progress.

Prevention: Understand the importance of each guideline and commit to adhering to them.

Solution: Regular consultations with the orthodontist to reinforce the significance of compliance and rectify any lapses.

Post-Treatment Considerations for Straightened Teeth

The Role of Retainers in Maintaining Straightened Teeth:

Importance: After the active phase of orthodontic treatment concludes, teeth have a natural tendency to drift back to their original positions. Retainers prevent this relapse.

Types: There are different types of retainers, such as removable retainers (like Hawley or clear plastic retainers) and fixed or permanent retainers (bonded wire behind the teeth).

Duration of Retainer Use:

Initial Phase: Immediately after treatment, retainers are usually worn full-time, except during meals and oral hygiene activities.

Long-Term: After the initial phase, many orthodontists recommend nighttime wear indefinitely to ensure the teeth remain in their new positions.

Frequency Adjustments: The orthodontist might adjust the wear frequency based on individual needs and observed stability.

Potential for Teeth to Shift Back:

Reasons for Relapse: Aging, gum or bone loss, oral habits, growth, or other natural forces can cause teeth to shift over time.

Prevention: Regular wear of retainers as prescribed, maintaining good oral hygiene, and regular dental check-ups.

Monitoring: It’s essential to monitor any shifts or changes in the teeth alignment. If noticed early, minor shifts can often be easily corrected.

Remember, post-treatment care is just as crucial as the teeth straightening process itself. Adhering to post-treatment guidelines ensures that the time, effort, and resources invested in achieving a beautiful smile have lasting results.


Maintaining oral hygiene with braces requires diligence and consistency, but the results are well worth the effort. By following these tips for maintaining oral hygiene with braces, you can minimize the risk of dental issues and ensure a healthy smile throughout your orthodontic journey. Remember to brush regularly, floss diligently, rinse with mouthwash, and attend regular check-ups with your orthodontist. With proper care, you’ll achieve a beautiful, healthy smile that lasts a lifetime.
