Airway Obstruction in children is characterised by mouth breathing, snoring, tooth grinding, bedwetting, allergies or frequent ear or other ear/nose/throat infections. Breathing is primary and when obstruction is present, the body adapts muscle positions to create as much airway space as possible. If muscle positions are not normal, then bones grow abnormally.

Facial asymmetries and some TMJ dysfunctions (jaw joint problems) can also be attributed to orofacial muscle imbalances and deviate tongue postures due to airway interferences. The following is list of symptoms associated with airway obstruction in children:
85% of orofacial growth is accomplished by the age of twelve. Therefore, early identification of airway interferences, with diagnosis of the underlying cause, is essential to prevent orofacial growth abnormalities. If you, your dentist, dental hygienist or paediatrician observe any of the above symptoms and suspect possible airway obstruction in your child, evaluation by an ENT (ear, nose and throat) physician should be undertaken.
Did you know that the way your child breathes can affect the development of his or her jaws and facial structure influencing how the teeth fit together? Normal breathing should occur through the nose with the mouth closed. However, if the nasal passage is somehow obstructed, mouth breathing often results. Generally, nasal airway obstruction is caused by one or more of the following: (see figure 1)
All of the above causes the child to breath with his or her mouth open. This open mouth posture causes the facial muscles to generate unnatural constrictive forces on the underlying bony structures (See Figure 2A). Narrowing and elongation of the upper jaw often is the result of such forces (see Figure 2B). In addition, the jaws tend to grow
apart, often causing front open bites which affect the position of the tongue and other facial structures. 
Also, because the lower jaw is dropped for mouth breathing, it tends not only to grow apart from the upper jaw, but also becomes positioned further back than normal, causing an overbite (Figure 2C).
How the tongue rets in the mouth can also negatively affect facial growth. The tongue at rest should be high in the mouth which stimulates normal growth of the maxilla (upper jaw). Enlarged tonsils force the tongue in a downward and forward position which pushes on the lower jaw and the lower teeth (tongue trust). This in turn can contribute to prognathism (protruding of the lower jaw) by overstimulating jaw growth (Figure 3).
Please keep in mind that there are many other factors beside airway considerations that affect dental-facial development (ie. genetics, muscular tone, tooth and jaw sizes, allergies etc). There for addressing just these airway interferences will not always guarantee correction of dento-facial problems. However, if airway interferences are eliminated before facial growth is completed, a suitable environment will be establishes to promote a more normal development of the orofacial structures. This can eliminate or simplify the need for extensive orthodontic treatment. Also in cases where airway interferences have been eliminated, relapse of orthodontic treatment is greatly reduced. The results include not only a more stable dentition and bite, but also a more pleasing facial appearance for your child.
The following professional references have been provided for you and your medical practitioner if they would like to know more about the effects of airway obstruction upon facial growth.
It’s normal for children to snore when they are tired isn’t it? The answer to that is actually – NO! Too often we assume snoring to be the social norm for tired people (big and small) however research has shown that snoring may be more detrimental to our health then we know it. Whilst everyone knows what snoring is, it’s also important to know that heavy, audible breathing also falls under the same category as snoring and is just as bad!

Snoring, or heavy breathing whilst sleeping, is that deep annoying sound that one makes when their airway is blocked. Blocked airway? Yes! That’s right – snoring is due to you or your child not being to breathe properly when sleeping. The simple fact is that if you don’t breathe well when sleeping – you or your child may not be getting a proper night’s rest. We all know how important sleep is! It’s imperative for health and development and this is even more important in our children.
Children can suffer from numerous sleep conditions that severely affect their development. The problems caused by the sleep issues can manifest in permanent problems later on in adulthood that are very difficult/ impossible to correct. This is why problems are best diagnosed and treated when young.
We recommend booking in your children with us so that we can do a Dental & Airway assessment. From there, we may recommend a few options:
The first port of call is to consult a paediatric ENT specialist (ear, nose and throat specialist) or an Oral Myology clinic. ENT experts will check for obstructions in your child’s airway and ears whilst Oral Myology clinics will check your child’s breathing and muscles. Examination may include a scope (flexible camera through the nose), Imaging (e.g x-rays/CT scans), Physical examinations, and sleep studies.
Depending on what is wrong, treatment options include Surgery (best done when young so they recover well), muscle exercises, breathing exercises or medications such as Nasonex.
Even after treatment, the child usually has to relearn how to breathe properly through the nose. This is why it is better to treat early because a habit is easier to unlearn when you are younger.
Early Interceptive Orthodontics is basically doing orthodontic work while a child still has a mixture of primary (baby) and permanent teeth. This typically occurs between the ages of 7 to 12 although this can vary depending on the dental development stage of the child.
The advantage of early treatment is that the early diagnosis and treatment of your child may help an orthodontic problem earlier whilst often minimizing more serious orthodontic problems from occurring. By lessening these problems early, later orthodontic treatment may be shorter and easier (or not required in some cases).
It’s important to note that Early Interceptive Orthodontics Treatment may be only one part of your Orthodontic journey. It is very likely that you will need to have further treatment such as braces or clear aligners to straighten your teeth. Each case is different, and your dentist will inform you of your tailored treatment plan.
Braces worn only on the adult teeth, while your child still has baby teeth. These normally only involve the front 4 incisors and the first adult molar. This may or may not be used in conjunction with springs which help with some expansion. These are typically used to help resolve crowding in younger children.
Typically done with maxillary expanders (more information here). These can either be removable or fixed. Maxillary expanders help to widen the upper jaw by pushing the teeth and bone outwards, and typically involve turning a super screw.
Functional Appliance Therapy include the MARA appliance, Herbst appliance, Twin-Block appliance or Clear Aligners (Angel Aligner A6). Again, these can be removable or fixed. These appliances help to position the lower jaw in a more forward position, thereby encouraging faster growth of the lower jaw into a more favourable position (eliminating an overjet).
We DO NOT offer fixed functional therapy.
Below is a small list of examples (but not exhaustive) of when you might need Early Interceptive Orthodontics Treatment.
The cost greatly depends on the length of treatment and number of appliances used. The cost for this can range from $2,000 (including all appointments) for a simple appliance up to roughly $10,000+ for more complex functional treatments which involve the alignment of your teeth.
Whilst we are able to do most Orthodontic treatment here at Cranbourne North Dental, we occasionally may need to refer you to an Orthodontist.
As with all orthodontic work – you must wear your retainer after treatment or you may have orthodontic relapse.
Jaw expansion typically will last from roughly 6 months to up to 2 years, depending on the number of plates or devices used.
Orthodontics is the movement of teeth. Functional appliances help to correct the relationship between the upper and lower jaws and is usually either a removable plate or a glued in appliance.
Orthodontic Functional appliances help by ‘moving’ the jaws back or forwards into the correct jaw position. This movement can be combined with Orthopaedic Expansion.
The classic signs that you might need orthodontic functional therapy include the Class II bite or “weak chin”. This is when your chin is retruded or positioned too far back. The opposite, a Class III bite or “underbite” relates to those who have a very strong lower jaw that protrudes past the top teeth. The timing of functional therapy is crucial and is typically done in young patients aged 10 to 14.
It’s important to note that Functional Therapy may be only one part of your Orthodontic journey. It is very likely that you will need to have further treatment such as braces or clear aligners to straighten your teeth. Each case is different, and your dentist will inform you of your tailored treatment plan.
Commonly referred to as “plates” – these are dual arch (top and bottom jaws) appliances that force the jaws into their correct position. Examples include the classic Twin Block or the Bionator.
Similar to the above, however instead of plates, these are done with Clear Aligners. An example of a Clear Aligner brand we use for Functional Therapy includes the Angel Aligner A6 Mandibular Advancement Therapy.
These are glued-in versions of the above. The two classic examples of fixed therapy include the MARA appliance or the Herbst Appliance. These are great for patients with poor compliance, and occasionally can be combined with fixed orthodontic appliances (such as braces).
We DO NOT offer fixed functional therapy.
Depending on whether you need a Fixed (glued-in) or removal jaw expander, the process is fairly similar and involves:
Most functional appliances are designed to speed up the growth of the lower jaw. This is done by forcing the lower jaw to be positioned further forward into the proper relationship, allowing the jaw joint to grow and remodel into this new position. Severe cases may need the lower jaw to be position further forward slowly over a period of time. Once the correct relationship has been established, this position is held for a few months to allow the muscles to adapt to this new position (up to 6 months).
The cost greatly depends on the length of treatment and number of appliances used. The cost for this can range from $2,000 (including all appointments) for a simple appliance up to roughly $10,000+ for more complex functional treatments which involve the alignment of your teeth.
Whilst we are able to do most Orthodontic treatment here at Cranbourne North Dental, we occasionally may need to refer you to an Orthodontist.
As with all orthodontic work – you must wear your retainer after treatment or you may have orthodontic relapse.
Jaw expansion typically will last from roughly 6 months to up to 2 years, depending on the number of plates or devices used.
Sleep apnea is a common but potentially serious sleep disorder that affects many people without them even realising it. It occurs when breathing repeatedly stops and starts during sleep, leading to restless nights. Many people might dismiss the signs as simple snoring or fatigue, but untreated sleep apnea can lead to significant issues like heart disease, high blood pressure, and mood disorders. Understanding the early signs can help you identify whether you or a loved one might have sleep apnea, enabling timely intervention and treatment.
If you often feel tired after a full night’s sleep or your partner complains about your loud snoring, it might be time to have a professional check.
Here are key signs that may indicate sleep apnea:
Sleep apnea can have serious long-term effects on your health:
Treating sleep apnea depends on the seriousness of the condition, but there are several effective options available that can significantly improve your quality of life and overall health. Here are some of the most common solutions:
For mild cases of sleep apnea, lifestyle adjustments can make a significant difference:
CPAP is one of the most effective treatments for moderate to severe sleep apnea. It involves wearing a mask connected to a machine that provides continuous airflow, keeping your airway open while you sleep. This reduces snoring and prevents apneas from occurring, ensuring you get a restful night’s sleep.
A customised oral appliance, called a Mandibular Advancement Splint (MAS), often called a sleep apnea mouth guard, can be an effective alternative for those with mild to moderate cases of sleep apnea. This device helps keep your airway open by repositioning the lower jaw and tongue during sleep. Cranbourne North Dental can provide a custom-fitted Mandibular Advancement Splint to alleviate your symptoms.
In cases where other treatments aren’t effective, surgery may be recommended to address the physical causes of sleep apnea. Surgical options include removing excess tissue from the throat, repositioning the jaw, or even implanting devices to stimulate airway muscles.
For some individuals, sleep apnea may only occur when sleeping on their back. Positional therapy involves training the body to sleep in a different position, typically on the side, to prevent airway blockages.
Getting tested for sleep apnea is important for diagnosing the condition and starting the right treatment. Here’s what you can expect during the testing process:
Your first step is to visit a healthcare provider, such as a GP or dentist, who will assess your symptoms and medical history. If sleep apnea is suspected, they may recommend a sleep study or refer you to a sleep specialist for further evaluation.
In need of a sleep evaluation? All Sleep consults are currently performed by Dr Daniella Lim – however, all of our dentists are able to do an initial screening to determine if you are required to see Dr Daniella Lim. Book online now.
A sleep study, known as polysomnography, is the most accurate way to diagnose sleep apnea. This test monitors your breathing, oxygen levels, heart rate, and brain activity while you sleep.
There are two options for a sleep study:
Once the sleep study is complete, a sleep specialist will review the data to determine whether you have sleep apnea and how severe it is. They will then discuss the best treatment options based on your results.
After diagnosis, it’s important to follow up with your healthcare provider to discuss treatment options and begin managing your sleep apnea effectively. This might include lifestyle changes, the use of a CPAP machine, or a custom sleep apnea mouth guard.
Recognising the symptoms of sleep apnea is essential, but knowing when to seek help is just as important. If you or a loved one experiences any of the following signs, it may be time to consult a professional. Contact Cranbourne North Dental today to book a consultation for your sleep apnea.
A bright, white smile can significantly boost your confidence and leave a lasting impression. Teeth whitening has become increasingly popular as more people seek ways to enhance their appearance and maintain a youthful look. By learning how to whiten teeth and understanding the best methods for achieving a radiant smile, you can make informed decisions about your dental care and avoid the issues of ineffective at-home remedies.
Teeth discolouration is a common issue that affects many people. It can occur due to various factors such as the consumption of certain foods and drinks (like coffee, tea, and red wine), smoking, aging, and even certain medications. The enamel, or the outer layer of the teeth, can become stained or worn down over time, revealing the yellowish dentin beneath. This can not only affect the aesthetics of your smile but also your confidence and oral health. If you struggle with yellow teeth contact our friendly team today for options.
Looking to brighten your smile? Explore our special offers for professional teeth whitening today.
Professional teeth whitening performed in a dental clinic is one of the most effective ways to achieve a brighter smile. During an in-clinic procedure, a dental professional will apply a high-concentration whitening gel to your teeth. This process may be repeated multiple times to achieve a great result. This process can significantly lighten your teeth in just one visit, often achieving results that are several shades whiter.
Choosing professional teeth whitening over at-home methods offers several key advantages. While DIY kits and remedies might seem convenient and cost-effective, professional treatments provide superior results in a safer, controlled environment.
Professional teeth whitening treatments are conducted under the supervision of a dental expert, ensuring that the procedures are both safe and effective. The high-quality whitening agents used in dental clinics are more potent than those found in over-the-counter products, delivering better results without compromising the health of your teeth and gums. The custom made trays are what makes the biggest difference, ensuring that the bleaching product does not get diluted with saliva and most importantly not damage the gums.
Every individual’s dental needs are unique. Professional teeth whitening allows for a customised approach tailored to your specific situation. Your dentist will evaluate the condition of your teeth and recommend the most suitable whitening method. This personalised care ensures that you achieve the best possible results while addressing any underlying dental issues that may affect the outcome.
One of the significant benefits of professional teeth whitening is the longevity of the results. The high-quality materials and advanced techniques used in dental clinics help to maintain a bright smile for a longer period. Additionally, dentists provide advice on maintaining your newly whitened teeth, helping you extend the effectiveness of the treatment.
Undergoing teeth whitening in a professional setting means you have access to expert advice and support throughout the process. Dentists can monitor the progress and make any necessary adjustments to ensure optimal results. They can also address any concerns or questions you might have, providing peace of mind and confidence in the procedure.
While it may be tempting to try at-home teeth whitening remedies due to their accessibility and lower cost, these methods often come with significant risks. Here’s why professional treatments are a safer and more effective choice:
When it comes to teeth whitening, safety should always be a top priority. Consulting a dentist before starting any whitening treatment ensures that you choose a method that is both effective and safe for your specific dental condition.
