Jana's full-range of dental treatments

Preventive Dentistry

A six monthly check-up and clean is recommended to maintain a healthy oral environment. Jana's goal is to keep your natural teeth in as good condition for as long as possible. Good oral health has a direct impact on general health.

Anti-wrinkle micro injections

Jana has completed training to administer anti wrinkle injections in the facial area including frown lines on the forehead, crows feet around the eyes and in the glabella area. Botox and Dysport injections can also be used to treat Bruxism (teeth grinding). 

Cosmetic Dentistry

Jana is guided by a restorative approach to cosmetic dentistry, and administers whitening teeth, veneers, crowns and implants to her patients.

Root Canal Therapy


Root Canal Therapy is a sequenced treatment for the nerve of a tooth in order to eliminate infection and to protect the tooth from future bacterial attacks.

Emergency Dentistry


A dental emergency can happen at any time and includes knocked out or broken teeth, tooth abscess, gum swelling. These emergencies have to be taken seriously and should be addressed immediately to prevent more serious and permanent damage.

On all days, Jana has emergency appointment slots available to treat patients.

Sleep apnoea splint

Jana has helped many patients get better sleep that contributes to the health and overall quality of life, with oral appliance therapy. She customises the fit of a splint, a device that looks something like a mouthguard.


It repositions the jaw slightly forward and open and depresses the tongue to prevent tissues from blocking the airway. a sleep study by a sleep physician is recommended to see if this device is suitable for you.
