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 decolourations 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 Tooth 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.

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.

Some people will experience increased tooth and gum sensitivity during treatment. In most case this sensitivity will go away after treatment.

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

  • Finally, a dental service I can rely on and honestly don't mind visiting. Our whole family see Carolyn and her team on a regular basis. The general dental care we receive is wonderful. Carolyn's thorough yet relaxed and friendly manner leave us feeling like we have made the right choice in moving to her clinic from elsewhere. I personally had a problem with clenching/grinding my teeth at night, which was damaging and wearing them down. Carolyn suggested I have a specially moulded retainer made to wear whilst sleeping. I was worried it would be uncomfortable, or wouldn't really work, but I am absolutely amazed at its success, and it is actually comfortable. No further wear and tear on my teeth and no more waking up with headaches. Also, thank you Carolyn for all your help and guidance through my recent, major wisdom tooth extraction.

  • Thanks Carolyn and co for the care extended to Team Collett over the last four years. We really couldn’t be happier! We have one child who now wants to study dentistry and adores all the gory stories. And another that will now happily turn up for the joy of choosing the wackiest sunglasses. The journey with him in particular has included star jumps to shake out nerves, text messages from the Tooth Fairy congratulating him on his bravery, the fantastic monster paste to encourage brushing performance, and now matching emoji glasses. We really can’t thank you enough for the empathy and creativity used, but most importantly the amazing professional care. We tell everyone how amazing you are!

  • I can’t recommend Newmarket Family Dental Care highly enough!  From my first contact with the team, throughout my dental work, to the follow up calls – every stage with Carolyn and her lovely team exceeded all my expectations and put any nerves I had at ease. They even supplied me with a pink unicorn hot wheat sack, blanket and funky glasses…ever seen anyone so happy and at home having their wisdom teeth extracted?  If you’re a nervous patient looking for a lovely dental team, or just wanting excellent dental treatment from a well trusted and highly skilled dentist, don’t look past Newmarket Family Dental Care!  Thank you team!

  • Finding Carolyn was one of the best things that happened to me since I moved to Auckland 2 years ago. I've had my share of bad dentists over the past couple of decades, which was both costly and painful. So when my dental floss got stuck in a problematic filling, I got really nervous with the prospects of seeing a new dentist. As Carolyn was trying to fix the bad work of a previous dentist, the filling broke. My gums were bleeding a lot because of the bad filling, and I had to take more injections so that Carolyn could continue working on my tooth. I got so nervous that my legs started shaking. At this point, Carolyn did two unforgettable things. Firstly, I could see in her eyes that she felt empathy for my suffering, and she did everything in her power to make me feel safe in her capable hands. Secondly, she fixed my tooth after 10 years of discomfort and two bad dentists. I am grateful for Carolyn with all my heart.

  • Carolyn and her team provide an outstanding dental service. Carolyn seems very up to date with best practice and new research in dentistry and dental health. She seems very thorough and precise, and determined to deliver a quality outcome that fits a patient’s needs and preferences. I was particularly impressed with Carolyn’s attention to detail in finding a way of making a large filing replacement work in a tooth that was in a difficult location with uncertain strength in its remaining enamel walls. Carolyn crafted the replacement to fit extremely well in a manner that seems to have maintained the required strength. I was also impressed with her attention to detail and current best practice in oral health, particularly the relationship between diet (high fruit intake) and dental hygiene.

  • 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.

  • Good morning Elaynor Thank you for the follow up call. The treatment has worked well and I have recovered fully. My long term association with your Clinic and repeated visits are a testimony of the good and professional care provided by Dr. Langrell-Read and her staff. I am always impressed with her eye for detail and the ability to listen and to communicate with her patient regarding the treatment planned and undertaken. I have recommended her services to my daughter in law.
