sevices snoring


Grinding or clenching your teeth (bruxism) can not only damage your teeth, cause headaches and jaw joint (TMJ) pain, but it can also be a sign of a sleep disorder. Sleep bruxism (grinding/clenching at night) is considered a sleep-related movement disorder and can be related to snoring and sleep apnoea, which can have effects on your general health.


Snoring is not a laughing matter (especially in children). It indicates a physical obstruction in your airway and a reduction in oxygen levels that affects every part of your body. It also disrupts the sleep of your bed partner!
Medical research shows that sleep disordered breathing (causing sleep deprivation) is linked to chronic health problems like high blood pressure, obesity, depression, diabetes, heart disease, dementia/alzheimers, cancer, strokes and the list goes on.

In children, enlarged tonsils and adenoids can physically block their airways. This results in changes to their breathing and swallowing patterns, which affects their growth and development of their face and jaws. This can often result in narrow upper jaw, crowded/crooked teeth, underdeveloped lower jaw, mouth breathing or open bite. Interceptive orthodontic treatment is often called for in this group of patients.

It comes as a surprise to most of our patients that a dental assessment can reveal that a patient may have some sleep disorders! Here at Bright-On Bay Dental, Dr Janice looks beyond the teeth and brings a holistic approach to looking after her patients.
