What is Myofunctional Appliance?

  • Myofunctional appliances are intraoral devices that utilize the forces of orofacial muscles to guide and influence dental and skeletal growth and development. It is also sometimes called “tongue trainer”.

  • It can be comparable to nightguards in certain aspects, such as their intraoral design and nighttime wear, but their purposes are different.

  • It is a preventative treatment that attempts to:

    • correct breathing habits, encourage nose breathing,

    • train tongue positioning/hyperactivity

    • desensitizing patients to intraoral appliances

  • It is well known that poor habits can affect jaw growth/bite patterns which contributes to orthodontic issues such as underbite, underdeveloped jaws and more.

    • The primary goal of myofunctional treatment is to reduce these effects and hopefully reduce the severity compared to non-treatment.

  • It is often prescribed for early intervention for children with already apparent orthodontic issues but not yet suitable for full orthodontic treatment.

What are the Risks and Limitations?

  • Doctor supervision and prescription should always be followed

    • Certified Orthodontists are the best professionals to determine when the patient is ready for orthodontic treatment or not.

    • If any questions arise, remember to address it to your orthodontist as soon as possible.

  • Generally, the appliance carries low risk when proper oral hygiene is maintained and periodic monitoring is performed—even with long-term use.

    • It is important that the appliance is thoroughly cleaned each day.

    • Our office can provide additional tips and guidance to help ensure effective cleaning and safe use.

  • It is important for the patient to understand that:

    • The extent of improvements depends on patient’s compliance and individual’s biology

    • It is understood that since it involves soft tissues, it is NOT a precise treatment

    • Will still likely require orthodontic treatment after, involving metal fixed appliances, braces and/or clear aligners

    • Myofunctional treatment alone is insufficient to resolve all major orthodontic issues
