FAQ'S

  • What causes bad breath and how can I treat it?

    There are many causes of bad breath but the main ones would be decayed teeth and diseased gums.

  • Why do wisdom teeth give so much trouble?

    They are hard to reach being so far back. Hence, if not properly cleaned, decay can set in. There is also very little space at the rear so they have insufficient room to come through. Thus, they become wedged in or “impacted”. 

  • What is endodontic treatment?

    This is also called root canal therapy. The infected tooth or damaged pulp is removed from the inside of your tooth. Files are used to clean out the canals and hypochlorite solution, together with saline and EDTA are used to rinse the canals. Once thoroughly cleaned and sterilised, the canals are then sealed with a filling material to prevent further infection. The treatment can take up to 3 visits, depending on how complex the case is. At each visit, the tooth will be isolated with a sheet of rubber, also called rubber dam, to keep the tooth clean and dry so that the canals remain sterilised. An X-Ray is taken at the end of the treatment to confirm that the canals are all sealed to the end of the tip. Sometimes, sedative dressings are placed inside the tooth and temporarily filled to allow the tooth and the surrounding tissues to settle. 

  • Is there an alternative to endodontic treatment?

    There are only 2 choices for an infected tooth: an extraction to remove the infection or root canal therapy to save the tooth. If the tooth in question is a functional tooth and it enhances one’s appearance, it is a tooth worth keeping. There is no real substitute for your own tooth. It is far more efficient in chewing and biting than an artificial tooth.

  • What is gum disease and how do I know if I have got it?

    Gum disease is also know as periodontal disease. It occurs when plaque, a film of bacteria, is allowed to build up on teeth. Toxins produced by the bacteria inflame the gums. This early stage of periodontal disease is called gingivitis and is reversible. If not treated, gingivitis can develop into periodontitis.

  • Why are my teeth sensitive to hot and cold and sweet foods?

    A tooth consists of the visible crown and the invisible root. There are 3 distinct structures called Enamel, dentine and pulp. When a tooth is sensitive it is usually because the dentine is exposed. Gum recession exposes the roots of the teeth and these are less insulated against cold food and drinks. The microscopic dentine tubules contain fluid which moves when exposed to cold, heat, touch or high sugar concentrations in the mouth. This stimulates the nerve and causes pain.

  • How do I care for my new dentures?

    Caring for your dentures is important as like natural teeth, they become dirty as they accumulate food debris and bacteria which can result in swollen gum, discolouration and bad breath. Proper cleaning is most important for partial denture wearers as food can get caught between the denture and natural teeth (eg around the clasps) which can lead to tooth decay.

  • What are dental implants?

    They are the closest possible replacement to natural teeth. They provide a stable foundation for eating and smiling with confidence. They can remove the need to compromise healthy teeth for a bridge and can eliminate pain caused by ill fitting dentures.

Dear Valued Patient,


I would like to thank you for your trust, loyalty, confidence and friendship throughout my thirty six years career in dentistry. I have been fortunate enough to thoroughly enjoy my professional career and so, it is with mixed emotions that I now formally announce that I have sold my practice. 


I have many special memories which will always be dear to my heart. I have learnt many things from you as we have discussed the more interesting things life presents, including food, gardening, the economy and of course, my beloved Ziggy.


I have had the privilege of treating three generations in some families and that only shows how much older I am than when I first started out! It is also a reflection of the enduring relationships I have built and continue to treasure.

I think the time has come to pass on the reins to another and to turn my attention to family, rest and recreation. I am really enjoying being a grandfather and love spending time with Benjamin. He is growing far too quickly and I want, very much, to be a part of his early years.


It took some time for me to formally announce the sale of the practice as I wanted to ensure that you would receive the best possible care. I had a number of candidates who were interested in assuming my practice. I finally selected Dr Alex Sebastian to continue the good will of the practice.

Alex is the principal at his own family practice in Narrabri, where he runs a busy, progressive and successful practice. He has an excellent reputation and is caring, empathetic and highly committed to providing exceptional quality care for all his patients in the many facets of dentistry.

Alex is a great communicator and since starting at the practice, many patients have warmed to him and are impressed by him. The practice continues to grow as he is expanding the number of days and hours, hence making it easier to schedule appointments for you.


Going forward, I plan to maintain a presence at the practice on a part time basis, currently Mondays to Wednesdays, working closely with Alex and helping him get to know your specific oral health care needs. This will ensure an eventual seamless transition. Please feel free to contact me during surgery hours over any queries you may have. As always, I will avail myself.

Dee, Mabel and Emily, our dependable and loyal staff are staying on with Alex. They will continue to assist you with your enquires. The surgery location remains the same, as does the telephone number.


I am confident you will be cared for and pleased with Alex and I hope you will extend him the same courtesy and loyalty you have afforded me over the years as he is passionate about what he does and will give his utmost best at all times.


Once again, together with my wife, Monica, we thank you again for your long- standing support. We look forward to the next chapter of life and wish you all the very best.



Kind Regards,


Michael Sim
