What Causes Orthodontic Problems?

From 6-10 years of age, children are getting their first permanent teeth. At this stage, the teeth can become crowded and the jaws misaligned. Habits such as mouth breathing, incorrect lip and tongue function (known as poor myofunctional habits) are the major causes of poor jaw development and tooth alignment. Research shows that these problems continue through to the permanent dentition, requiring complex orthodontic treatment.

Braces and extractions do not resolve these problems and are best treated as soon as they are evident. These habits are easier to correct in the growing years. Once the causes are corrected, natural growth and dental alignment can take place

Problems Associated with Mouth Breathing

Apart from affecting jaw and facial development, mouth breathing is also one of the main contributors of Sleep Disordered Breathing (SDB) problems. Symptoms include

  • Snoring
  • Morning Tiredness
  • Learning difficulties
  • Interrupted sleep
  • Obstructive Sleep Apnea where a child stops breathing at certain times during the night

Is Orthodontics with Braces / Invisalign the Only Treatment Option?

Since 1989, Myofunctional Research Co. (MRC) have developed appliances that provide a more effective option for the growing child with orthodontic problems. The appliances are designed not only to straighten teeth, but also to treat the underlying causes of crooked teeth by correcting poor oral habits such as mouth breathing, tongue thrust and incorrect swallowing patterns.

Unlike traditional orthodontics, the primary goal of MRC’s approach to treatment is to achieve naturally straight teeth for life – often without the need for braces or retainers. Treating the causes of crooked teeth also improves general health and allows children to reach their maximum growth potential.



Myofunctional Treatment and MYOBRACE is focussed on treating the causes of teeth crowding using specific removable appliances and specific exercises for the oral muscles. By removing the causes leading to crooked teeth your child will develop straighter teeth and proper jaw alignment naturally.

Main causes of teeth crowding include:-

  • Tongue tie
  • Mouth breathing
  • Habits such as thumb-sucking
  • Poor lip and tongue posture from extended use of pacifiers or milk bottles.

Normal Vs Crowded Teeth


The function of the tongue, cheeks and lips determines tooth position. Correct facial growth depends on correct function and breathing patterns.

How It Works?

MRC has pioneered the use of appliances to correct myofunctional habits in growing children and has proven success in orthodontic correction without braces. This treatment also leads to better facial development in growing children. The key to this treatment is correcting the position and function of the tongue, obtaining correct nose breathing and retraining the oral muscles to function correctly. At Coast Dental, a programme comprising of specific breathing exercises, tongue exercises, lips exercises, swallowing exercises and nutrition will be customised for your child. These exercises together with the use of the myobrace appliances will correct myofunctional habits and retrain the oral musculature to align the teeth. A client log in password will be issued for all patients undergoing the Myobrace programme to keep track of their exercises on their home desktop, laptop, handphones and other smart devices
