Metal braces are a commonly used option for treating moderate to severe crowding. They are fixed to the teeth during treatment, giving the orthodontist control over the position of individual teeth. This can be useful when teeth are rotated, tilted, overlapping, or sitting outside the normal dental arch.
Crowded teeth cannot always be corrected by simply moving them into a straighter position. The available space in the dental arch has to be considered, along with the position of each tooth and whether tooth extraction is necessary. As treatment progresses, teeth gradually change position, and some stages can look quite different from the final result. After the braces are removed, retainers are used to hold the teeth in their new positions.
For patients considering metal braces, it is useful to know what happens during treatment, how crowded teeth change, what can affect the final result, and how to look after the teeth and braces during treatment.
Why Are Metal Braces Used for Complex Crowding?
Metal braces consist of brackets attached to the teeth and an archwire that passes through the brackets. The wire applies gentle, controlled pressure to change the position of the teeth over time. As the braces stay attached to the teeth during treatment, pressure is applied consistently without the patient having to put the appliance in or take it out.
For crowded teeth, metal braces can be used to:
• Correct rotated teeth – The bracket and archwire can gradually change the direction of a tooth that has turned away from its normal position.
• Align teeth within the dental arch – A tooth positioned towards the tongue, palate, or cheek can be gradually aligned with the other teeth.
• Control the position of the tooth root – Braces can affect the position of both the visible part of the tooth and its root, which is important when a tooth needs to be placed in a more upright position.
• Handle significant tooth movement – With severe crowding, there may be limited space for the teeth to reach their normal positions. Fixed braces give the orthodontist more control when larger changes are required.
• Improve the bite – Elastic bands and other orthodontic attachments can be added when the upper and lower teeth do not fit together correctly.
Before treatment begins, the orthodontist assesses the amount of crowding, the bite, the position of each tooth, and the available space. This assessment determines whether metal braces are a suitable choice and whether other steps, such as tooth extraction, may be required.
How Do Metal Braces Create Space for Crowded Teeth?
Crowded teeth need space before they can be aligned. The approach depends on how much space is required, the bite, and the condition of the teeth, gums, and supporting bone.
Aligning With or Without Extraction
In mild to moderate crowding, braces can often align the teeth using existing space or by creating additional space within the dental arch. In severe crowding, removing one or more teeth may be needed. Whether crooked teeth can be corrected without extraction is decided during the orthodontic assessment.
Interproximal Reduction With Braces
Interproximal reduction (IPR) removes a small, controlled amount of enamel between selected teeth. It can be combined with braces when a limited amount of extra space is required.
Springs and Power Chains
Small coil springs may be placed on the archwire to open space for a crowded tooth. Elastic chains, called power chains, may be used to close spaces or bring teeth closer together. These attachments are adjusted during routine appointments.
Bonding Displaced Teeth Later in Treatment
A tooth that is severely out of position may be left without a bracket at the beginning of treatment. Space is first created in the dental arch, and the bracket is added once there is sufficient space to place the tooth into alignment.
What Changes During Treatment for Crowded Teeth?
Teeth gradually change position with metal braces, and the appearance can vary at different stages of treatment. Some changes that seem unexpected at first are part of the process of correcting crowding.
Why Teeth Can Look Worse Before They Look Better
At the beginning of treatment, some teeth may appear more uneven or may tilt forward slightly. The initial stage focuses on creating space and levelling the dental arch, so the teeth can look different before they reach their final positions. This is a normal part of treating crowded teeth.
Why Small Gaps May Appear
Temporary gaps can appear as teeth are separated, rotated, or repositioned. These spaces are usually closed later in treatment as the teeth are brought into their final positions.
Why the Wires Are Changed in Stages
Treatment usually begins with thin, flexible wires that apply light pressure to severely crowded teeth. As alignment improves, these are replaced with thicker, firmer wires that provide more precise control over the position of the teeth and their roots.
Adjustment Appointments
Regular appointments are needed to change wires, adjust attachments, and check the progress of treatment. The interval between visits depends on the treatment plan and how the teeth are responding.
How Long Treatment Takes
Treatment time depends on the severity of crowding, whether extraction is needed, the bite, and how the teeth respond to treatment. Attending appointments as scheduled and following the orthodontist’s care instructions can keep treatment progressing as expected.
What Results Can Be Expected in Crowding Cases?
Metal braces can improve the alignment of crowded teeth and the way the upper and lower teeth fit together. The final result varies based on the severity of the crowding, the type of orthodontic treatment required, the health of the gums and supporting bone, and how well the recommended care is followed.
Things to Consider During Treatment
• Wearing elastics or other attachments as instructed – These are used when additional control is needed during treatment.
• Attending adjustment appointments as scheduled – Regular visits are needed to make changes to the braces and check the position of the teeth.
• Avoiding damage to brackets and wires – Hard, sticky, or chewy foods can damage the braces and interrupt treatment.
• Maintaining good oral hygiene during treatment – Brushing and cleaning between the teeth reduces the risk of tooth decay and gum problems.
• Wearing retainers after the braces are removed – Retainers keep the teeth in their new positions after active treatment.
Small Triangular Gaps Near the Gums
When overlapping teeth are straightened, small triangular spaces can become visible near the gum line between some teeth. The overlap may have covered these spaces before treatment. Depending on the shape of the teeth and the amount of space, the appearance can sometimes be reduced by reshaping the areas where the teeth touch.
Why Rotated Teeth Need Extra Attention
Teeth that were rotated before treatment can have a higher chance of rotating towards their previous position after the braces are removed. The tissues around the tooth need time to adjust to the new position, which is why retention is particularly important for previously rotated teeth.
Retention After Braces
Once the braces are removed, a retainer is used to keep the teeth in their new positions. This may be a removable retainer, a fixed retainer bonded behind the teeth, or both. Previously crowded teeth often require long-term retainer use because teeth can gradually shift after orthodontic treatment.
How to Care for Crowded Teeth During Braces Treatment
Crowded and overlapping teeth can be more difficult to clean, and brackets and wires can give plaque more places to build up. Good oral hygiene during treatment is important for protecting the teeth and gums while the braces are in place.
Cleaning Around Brackets and Overlapping Teeth
• Brush around each bracket – Clean above and below the wire, as well as along the gum line.
• Use interdental brushes – Small brushes can clean between the teeth and under the archwire.
• Use floss threaders or orthodontic floss – These make it easier to pass floss under the wire and clean between the teeth.
• Clean areas where teeth overlap – Plaque can build up where teeth remain close together or overlap, particularly during the early stages of treatment.
• Use fluoride toothpaste – Fluoride protects the enamel around the brackets and reduces the risk of tooth decay.
Foods to Avoid
Hard, sticky, and chewy foods can loosen brackets or bend wires. Examples include hard nuts, ice, sticky sweets, and chewing gum. Foods such as apples and raw carrots can be cut into small pieces before eating.
Discomfort After Fitting and Adjustments
The teeth may feel tender for a few days after the braces are fitted and after adjustments. Soft foods can make eating more comfortable during this time. Orthodontic wax can be placed over brackets that rub against the cheeks or lips.
Loose Brackets or Wires
If a bracket comes loose or a wire causes discomfort, inform your orthodontist. Do not try to cut or remove the wire yourself.
Are Metal Braces or Clear Aligners Better for Severe Crowding?
For severe crowding, metal braces are often preferred because they provide precise control of rotated, tilted, and displaced teeth. Clear aligners can treat many cases of mild to moderate crowding, but severe cases can involve tooth movements that are more difficult to manage with aligners. The suitable option depends on the orthodontic assessment.
The following points are considered when choosing between metal braces and clear aligners:
• Severity of crowding – Larger changes in tooth position and severely displaced teeth are often treated more predictably with fixed braces.
• Root control – Braces provide greater control over the position of the roots, which is important when a tooth has to be repositioned significantly.
• Extraction cases – When teeth are removed, closing the spaces left by extraction is often more predictable with fixed braces.
• Patient cooperation – Clear aligners need to be worn for most of the day, usually 20 to 22 hours. Metal braces remain attached to the teeth and do not depend on daily wear time.
• Appearance – Clear aligners are less visible, which some patients prefer for mild to moderate crowding.
The final recommendation depends on the severity of crowding, the bite, the position of the teeth, and the findings from the orthodontic assessment.
Metal Braces Treatment at Al Miraya Medical Center
At Al Miraya Medical Center, our orthodontic specialists provide metal braces and other orthodontic options for children, teenagers, and adults. Each case is assessed individually based on the severity of crowding, tooth position, bite, jaw development, and the health of the gums and supporting bone
For patients with crooked or crowded teeth, the orthodontic assessment covers:
• Available space – Whether there is sufficient space within the dental arch or whether additional space is required.
• Tooth position – The position, rotation, and angle of individual teeth.
• Bite – How the upper and lower teeth fit together.
• Extraction requirements – Whether one or more teeth need to be removed as part of treatment.
• Suitable appliance – Whether metal braces or another orthodontic option is appropriate for the case.
When metal braces are recommended, treatment is carried out in stages with regular appointments to check the position of the teeth and make adjustments. After the braces are removed, retainers are used to keep the teeth in their new positions.
