Tooth Whitening

Tooth whitening is a bleaching process that lightens stains in the enamel of your teeth, to give a brighter tooth colour. Tooth whitening may be done to live teeth and to teeth that have had root canal treatment. 

Newmarket Family Dental offers dentist strength whitening treatments that are effective and affordable. Dr Carolyn Langrell-Read will check your teeth and recommend the most appropriate treatment method to suit your individual needs and the level of tooth lightening you desire.

Before you have your teeth whitened it is important to check your teeth are suitable to be treated. Conditions such as dental decay, cracks, and gum disease may need to be treated prior to the whitening procedure. Root filled teeth will often need more advanced whitening procedures to remove the stain from within the tooth. Teeth with fillings and crowns will not lighten during the whitening process and may need to be changed after the whitening process has been completed.

Prior to undertaking a whitening process the teeth will need a professional cleaning procedure (Scaling and Polishing) to remove decolouration’s caused by plaque / calculus deposits and extrinsic stains such as tea / coffee / wine / coloured juices / smoking. If the bacterial deposits have resulted in gum infection (gingivitis or periodontitis) then this will need to be treated prior to commencing.

Teeth with recession related to tooth brush abrasion or to past gum disease may not be suitable for whitening processes.

How Does Teeth Whitening Work ?

You already know that whitening works, but do you know how?

Stains on teeth can be classified in one of two ways: extrinsic or intrinsic.
Extrinsic stains appear on the surface of your teeth. Intrinsic stains live between
the microcracks in your enamel and deep within your dentin (the layer of your tooth
underneath your enamel). Whitening toothpastes and mouth rinses may be able to remove
some of the extrinsic stains on your teeth. But only teeth whitening agents can remove
the stubborn extrinsic stains and the unsightly intrinsic stains that cause your teeth
to look discolored.

The gels used at Newmarket Family Dental Care contain an active whitening ingredient (either carbamide peroxide or hydrogen peroxide) that penetrates your enamel to get to discolored molecules. Oxygen
molecules from the whitening agents react with the discolored molecules in your teeth,
breaking the bonds that hold them together. The oxygen molecules spread, whitening the
entire tooth. As a result, you are left with a brighter, whiter smile.

Caution should be taken if you consider using home bleaching treatments without professional guidance.

Professional Prophylaxis (cleaning and scaling) will remove unsightly bacterial plaque and hardened calculus deposits along with surface stains (Tea / coffee / wine and Tobacco) leaving your mouth fresher your gums healthier and the bonus of a new brighter / whiter smile.

Root filled teeth are lightened by placing a bleach agent inside the tooth. This can be undertaken immediately following the completion of the root canal treatment, or at a later date if the tooth has discoloured in the years following root canal treatment.

The tooth is partially opened into where the root canal filling was placed – the root filling is sealed and the bleaching agent is placed inside the tooth. The tooth is then resealed and left for 7-10 days. It may be necessary to repeat the process 2-3 times to be effective.

If the root filling is older / poorly sealed or the tooth has signs of infection present the root filling will need to be retreated prior to the bleaching process.

Dr Langrell-Read will be happy to discuss options for reducing tooth sensitivity during and after the bleaching process.

Long term research indicates that the structure of the tooth is not changed by the process.

What Are my options if standard whitening processes are not effective for my teeth?

In some cases whitening may be ineffective or may not be the most appropriate treatment to whiten your teeth.

Alternative treatment such as Dental Crowns or Dental Veneers may be more appropriate to meet your individual needs.

Patient feedback

  • As a very anxious dental patient I was recommended Carolyn Langrell-Read by a family member who happens to be a dental nurse herself, high praise in itself. I have now been a patient since 1986 and am extremely happy with her caring and professional manner. I required a significant amount of work to be done and have been well informed throughout each stage of the process. Over the past few years my attitude has changed since my first visit when I was terrified to even walk through the door, recently I was so relaxed that I nearly fell asleep in the chair and not due to sedation!! That is due to Carolyn’s patient, kind and thoughtful nature, it makes travelling from the North Shore very worthwhile indeed.

  • I have known Carolyn Langrell - Read for 6 years. In this time she has treated my gum disease, suggested that I should consider braces, (my bottom teeth were breaking my top teeth), and given me superior dental treatment. Her skill in filling, reconstructing, capping and saving teeth some that have been filled generously with amalgam in the past is extraordinary. Her manner is friendly and professional. She gives you an excellent explanation (both verbal and written) of the treatment she proposes or has achieved. Her equipment is excellent and this combined with her expertise enables her to achieve a very high standard of dental work I feel very confident that Carolyn will look after my teeth in the future and I can recommend her as an exceptional dentist.
