FAQ's About In Chair Teeth Whitening in Gosnells

In-chair teeth whitening is best for individuals with healthy gums and teeth without restorations. People who have yellowish teeth are more likely to benefit from it. However, this cosmetic treatment is not suitable for everyone.

If you have front teeth that have been bonded or have tooth-coloured fillings, bleach may not be effective. The bleach will not change the colours of these materials, and they will stand out if you whiten your other teeth. Before going in for the tooth whitening procedure, consult with your dentist, especially if you have a lot of fillings, crowns, or dark stains.

Also, if you have any of the following, you may not be a good candidate for tooth whitening:

  • You have sensitive teeth.
  • You have dark stains or severe discolouration.
  • You use tobacco products.
  • In-chair professional teeth whitening
    In-chair treatments are among the most popular and common treatments since they provide quick results while taking an hour out of your day. Most bleach treatments, such as ZOOM, BOOST, and KOR Whitening, offer the most outstanding results on the market today.

    The procedure involves the use of one of the active ingredients, hydrogen peroxide or carbamide peroxide. Dentists can choose to use an LED light or not as part of the process.

    In-office whitening can whiten your teeth by two or three shades whiter in a single dental visit. Alternatively, you may choose to have tooth whitening while having your regular checkups, which are done every six months.
  • Take-home teeth whitening
    It is a more time-consuming and labour-intensive whitening treatment than an in-office whitening method. To make a custom-fitted set of moulds, your dentist will first make impressions of your mouth.

    Depending on how frequently you apply it, your dentist will provide you with six months’ worth of whitening trays and whitening gel. For a longer-term procedure, they’ll ensure there’s enough on hand so that you aren’t left short while waiting for the next batch.

    This technique is ideal for individuals who want a fast, efficient, and aggressive teeth whitening procedure.
  • Pre-whitening:
    The dentist will first take a look at the shade of your teeth. It is to give you an indication of how much whitening is required. It will also assist the dentist in determining how strong the whitening solution must be to achieve that shade.

  • Cleaning and drying:
    The dentist will then polish and clean your teeth with pumice. A dry surface best absorbs the whitening chemical, so your dentist may keep a gauze pad in your mouth for as long as necessary.

    Cleaning your teeth also aids in the removal of any existing plaque from your teeth before bleaching. A specific peroxide concentration will then be applied using retractors to prevent your gums, tongue, and lips from disrupting it.

  • Applying the whitening agent
    A certain hydrogen peroxide percentage is used, which will be the ideal bleaching agent for teeth whitening. The front of your teeth will be whitened, while the back will remain untouched. The goal of tooth whitening is to improve the appearance of your smile, and the backside of your teeth does not show.

    When applied to your teeth, the bleach solution penetrates and removes stains from the inside, whitening your teeth from the inside out. The solution will stay on the teeth for around 30 minutes before the dentist moves on to the next step.

  • Rinsing:
    The mouth will then be washed thoroughly. It is to ensure there is no residue of the solution left in your mouth. At times, the dentist will brush your teeth as well since the next step is applying fluoride treatment.

  • Fluoride treatment:
    Your teeth will be polished with fluoride varnish to maintain the brightness and whiteness of your teeth. Fluoride also aids in the removal of any existing plaque on your teeth.

Most in-chair whitening procedures take about 60 to 90 minutes. There may need to be several sessions to reach the desired shade, depending on how much lightening your teeth need. To maintain results, teeth whitening should be repeated regularly.


During the whitening process, you may experience temporary sensitivity. In this case, it occurs because of dentin exposure during treatment, which is otherwise protected by tooth enamel.

Furthermore, it’s always a good idea to talk with a dentist before undertaking any teeth whitening. If you have tooth sensitivity, it means that the tooth enamel on your teeth has already been damaged and needs protection. They would advise on the best type of process for sensitive teeth.

Gum irritation

One of the many hazards of teeth whitening is chemical burns. The solution might irritate sensitive tissue such as your gums and oral mucosa, resulting in soreness or a raw feeling for days.

The bleach will also cause your gums to turn white as soon as it comes into contact with them. It’s most likely the case if you’re using a professional whitening solution. Although this is the case, most tooth whitening solutions’ irritation will subside, and the soft tissue will return to normal soon after exposure. On the other hand, patients would be concerned about their gums after coming into contact with hydrogen peroxide or carbamide peroxide.


  • Keep your mouth healthy by following good oral hygiene, which includes brushing thoroughly at least twice a day and flossing regularly.
  • You may choose to use an electric toothbrush since they come with several advantages, but one of the most significant is their speed at removing plaque.
  • Regular dental checkups and cleanings from a hygienist are essential to keeping your natural teeth healthy—schedule appointments with your dentist twice a year. By doing so, you can prevent tooth decay and plaque from forming.


  • Eliminate or reduce the consumption of stain-causing foods and beverages.
  • To reduce contact between your teeth and sugary or acidic beverages, drink through a straw.
  • When you consume highly-pigmented food or drink, rinse your mouth with water or chew sugar-free gum afterwards to prevent staining your teeth.
  • Avoid smoking or the use of tobacco products. 

Typically, in-chair dental treatments cost around $260 per tooth.

Teeth whitening is typically considered safe, although some individuals are concerned that it might make their teeth weaker or that the chemicals are harmful to them. The cells of the gums can be damaged by the peroxide in teeth whitening solutions. It may also harm the nerves, blood vessels, and connective tissues of a tooth. In either case, if these chemicals are used excessively, they might induce tooth sensitivity and gum irritation.

Overapplication or incorrect usage of whitening gels might wear away tooth enamel and irritate the dental nerves. Chemical burn is a risk caused by teeth whitening. It can result in more severe discomfort and inflammation if the whitening product reaches the gums repeatedly.
