Chairside Teeth Whitening – In-clinic System

Professional whitening typically refers to teeth whitening professionally done by a dentist in a dental clinic. At NoFrills Dental, we offer patients a number of chairside teeth whitening brands; namely, Opalescence Whitening and Philips Zoom Whitening. Results are noticeable after a single session that lasts between 60 and 90 minutes.

Most tooth whitening products utilise between 20% – 40% of hydrogen peroxide gel or carbamide peroxide gel, this process is then enhanced through a lighting and heating elements which helps expedite the teeth whitening process through the breakdown of the whitening agent. A specially designed teeth whitening lamp is used illuminate the teeth with a gentle blue light that activates the peroxide substance.  

Breakdown of the peroxide material creates free oxygen radicals on the tooth surface, which then enter the enamel layer of the tooth structure, and whitens the tooth while doing so. 

Maintaining Your Bright Smile

Any results achieved from teeth whitening is not permanent and will slowly fade over the course of 8 – 12 months. The speed of this ‘fading’ varies from person to person and greatly depends on a variety of external factors, such as diet, social habits and overall oral health. 

Patients can typically help upkeep their white teeth by:

  • Having regular dental checkups every 6 months. 
  • Practice good oral hygiene habits such as using proper tooth brushing techniques.
  • Maintaining results through the use of take-home whitening kits.
Teeth Whitening Process
  • Gums and lips and prepared for the teeth whitening procedure by protecting them using a dental dam or other protective materials.
  • Whitening Gel containing peroxide material is applied onto the teeth
  • A specially designed lamp emitting harmless blue light is placed above the patient’s mouth, activating the whitening gel.
  • During this time, patients can relax while waiting for the gel to do its job.

Causes of Teeth Staining & Discolouration

Patients have asked our dentists “I’ve been brushing my teeth diligently all of my life but why are my teeth still so yellow?” Teeth staining and discolouration can be caused to a variety of factors, some of which aren’t even related to dental health. In general, the discolouration of teeth can be segmented into 3 types of causes: External Causes, Internal Causes and Age-Related Causes.

External causes include:
  • The consistent consumption of dark-coloured drinks such as red wine, tea and coffee.
  • Smoking is another common cause of teeth discolouration; due to the tar contained in cigarettes, causing teeth to turn dark brown or yellow.
  • Poor oral hygiene habit leading to the build-up of hardened yellow plaque.

Extrinsic stains can be removed by dentists through the use of various cleaning and whitening techniques. Moreover, patients can utilise whitening toothpastes that may help remove surface stains and reduce the amount of discolouration as well.

Internal causes include:

These types of stains cannot be removed, simply due to the fact that these stains are internal stains that cannot be removed by cleaning or abrasives.

  • Tetracycline – Antibiotics taken by young children or pregnant mothers may lead to this form of teeth staining.
  • Excessive Fluoride Application – excessive application of fluoride below the age of 8 down can cause white to brown spots on teeth.
  • Root Canal Treatment – The discolouration of teeth can also be caused by root canal treatments when part of the pulp have not been fully removed from the tooth. Causing teeth to become discoloured to be dark-grey or brown colour.
  • Traumatic Injury to Teeth – Injured teeth tend to look reddish, brown or pink.
Age related causes:

Age plays an important factor in the colour of teeth. Over time, the enamel layer of a person’s tooth gets worn off due to wear, erosion or the grinding of teeth, causing it to get thinner. This thinning of the enamel causes teeth to start developing a yellow hue.

Pre-Treatment Best Practices

  • Maintain Excellent Oral Hygiene Before Treatment: Make sure to brush your teeth before going for teeth whitening, get rid of any food particles through flossing if needed. Any food build-up will prevent the peroxide whitening gel from reaching those areas. Preventing patients from reaping the maximum benefits from the treatment. Our dentists encourage patients to undergo scaling and polishing before starting whitening treatment. 

Post Treatment Best Practices

  • Avoid Dark-Coloured Beverages & Foods: The first few days after teeth whitening treatment are crucial, as any consumption of dark-coloured drinks or foods may stain teeth. 
  • Avoid Acidic Food: Avoid consumption of acidic foods and beverages such as lemon, orange and lime. This is to reduce the risk of tooth sensitivity after treatment. Patients will be provided teeth desensitizers to help with the sensitivity.

Is Teeth Whitening Painful or Hazardous?

During teeth whitening treatment, most of our patients are comfortable as they enjoy a sound sleep or watch a movie. However, most patients experience some form of post whitening treatment sensitivity, which typically only lasts just a day. This sensitivity occurs as the teeth would have been dehydrated during the whitening process.

Once the teeth are rehydrated, the tooth sensitivity naturally vanishes. Patients should be in good oral health before starting any form of teeth whitening. Our dentists ensure that any existing oral health conditions are addressed before proceeding with teeth whitening. All products used in teeth whitening are safe and non-acidic. There isn’t going to be damage to the tooth structure. The by-products of peroxide only comprise of oxygen and water.
