Orthodontic Treatment for Patients with Periodontal Disease and Bone Loss

A history of periodontal (gum) disease does not automatically prevent a patient from undergoing orthodontic treatment. In many cases, orthodontics plays a valuable role in improving the long-term prognosis of teeth affected by periodontal disease — but only when undertaken with the right level of specialist oversight and careful timing.

Lusk Orthodontics, led by Dr Erfan Salloum, has extensive experience managing orthodontic treatment for adult patients with a history of periodontitis, bone loss, or reduced but healthy periodontium. Dr Salloum works in close collaboration with leading periodontists across Dublin to ensure that all such cases are planned jointly, sequenced appropriately, and delivered with the highest level of specialist oversight.

The Relationship Between Orthodontics and Periodontal Health

Periodontal disease damages the bone and soft tissue that support the teeth. When bone loss has occurred, the centre of resistance of each tooth shifts, which alters how teeth respond to orthodontic forces. This means that standard orthodontic force values and mechanics must be modified to account for the reduced periodontal support — if not, there is a risk of causing further bone loss rather than achieving the intended movement.

However, the relationship between orthodontics and periodontal health is not entirely one of risk. There is good evidence that correcting certain types of malocclusion can improve periodontal outcomes. For example:

• Correcting crowding and overlapping teeth improves the patient’s ability to clean effectively, reducing plaque accumulation in areas that were previously inaccessible
• Uprighting tilted teeth improves the bone architecture around those teeth and facilitates better periodontal maintenance
• Correcting excessive overbite or traumatic occlusal contacts can reduce the mechanical forces contributing to localised bone loss

Essential Pre-Treatment Requirements

Before orthodontic treatment can begin in a patient with a history of periodontitis, the following conditions must be met:

Periodontal disease must be fully controlled. Active periodontal disease — characterised by bleeding on probing, pocketing, and ongoing bone loss — is an absolute contraindication to orthodontic treatment. Moving teeth through infected or inflamed tissues accelerates bone loss and worsens the prognosis.

Periodontal stability must be confirmed. Stability means that disease activity has been arrested, the patient is compliant with a maintenance programme, and the treating periodontist is satisfied that the condition is under control.

The periodontist must be in agreement. Orthodontic treatment in these patients is only undertaken with the explicit agreement of the treating periodontist. Ongoing communication between both specialists is maintained throughout treatment.

How Treatment Is Modified for Periodontal Patients

Several adjustments are made to the way orthodontic treatment is planned and delivered in patients with periodontal disease or bone loss:

Lighter forces. Teeth with reduced periodontal support are more susceptible to adverse bone changes under heavy load. Orthodontic forces are reduced accordingly to achieve tooth movement without compromising the remaining attachment.

Slower treatment pace. Teeth are moved more gradually to allow the periodontal tissues adequate time to remodel and follow the moving root.

More frequent monitoring. Periodontal status is reviewed at more frequent intervals throughout treatment. Any sign of renewed disease activity or adverse tissue change results in immediate review and, if necessary, a pause in treatment until stability is re-established.

Careful appliance choice. Clear aligners can be advantageous in some periodontal patients because they are easier to remove for oral hygiene maintenance. Fixed braces, when used, must be managed with particularly rigorous home care.

Retention planning. Retention is especially important in patients who have experienced bone loss, as the risk of tooth movement and relapse following treatment is heightened. Permanent fixed retainers are commonly recommended.

Situations Where Orthodontics Is Particularly Beneficial for Periodontal Patients

Tooth uprighting. Molars that have tilted into the space of a missing tooth develop an unfavourable bone topography on the tilted side. Uprighting the tooth improves the bony architecture and can enhance the outcome of periodontal treatment.

Correction of crowding. Where crowding prevents effective brushing and interdental cleaning, straightening the teeth significantly improves the patient’s ability to maintain periodontal health.

Space management for implants. Where missing teeth are to be replaced with implants, orthodontic treatment can be used to create ideal spacing and ensure the implant is placed in the optimal position for both aesthetics and longevity.

Intrusion of over-erupted teeth. Teeth that have over-erupted following the loss of an opposing tooth can be intruded orthodontically to correct the occlusal plane and facilitate restorative or implant treatment.

Book a Specialist Assessment

If you have a history of gum disease or bone loss and are considering orthodontic treatment, book a consultation for a full assessment. Where appropriate, coordination with your periodontist will be established from the outset.
