TEETH WHITENING
If staining or tooth colour is something you would like to change, professional whitening may be an option. At Doncaster Hill Dental, we can assess your teeth, discuss what whitening may realistically achieve and explain the options available.

UNDERSTANDING TOOTH COLOUR
Professional whitening uses a whitening agent to lighten suitable natural tooth structure. It can change some discolouration, but different stains respond differently.
Whitening is primarily a cosmetic treatment. Whiter teeth are not necessarily healthier teeth, and whitening does not treat decay or gum disease.
Fillings, crowns, veneers, bridges and other restorations generally do not change colour with whitening. They may become more noticeable if the surrounding natural teeth lighten.
Tell your dentist about any dental work in your smile before deciding on treatment.
ASSESSMENT COMES FIRST
Your teeth and gums should be assessed before whitening. The cause of discolouration matters: surface staining, natural tooth colour and a tooth that has darkened after injury may need different approaches.
Decay, gum inflammation, cracks, damaged teeth and exposed root surfaces may need attention before cosmetic treatment.
Existing sensitivity and the location of fillings, crowns or veneers affect the options and the colour change to expect.
Discuss what you would like to change, your starting shade and any previous whitening. No particular final shade can be promised.
A check-up and clean can help assess oral health and remove some surface deposits. It is different from whitening. Choosing to leave healthy teeth their natural colour is also an option.
PROFESSIONAL SUPERVISION
In-chair whitening is performed at the dental practice. A professional whitening gel is applied to suitable teeth, with appropriate protection for the surrounding tissues, following the system’s clinical instructions.
Your dentist can explain the product proposed for you, its limitations and alternatives before you proceed.
Allow time for individual care. Appointment times vary with assessment, preparation and the whitening protocol used. Ask the team how much time to allow when booking.
WHAT TO EXPECT
Your dentist checks your teeth and gums and discusses your goals, sensitivity and previous dental treatment.
Discuss realistic colour change, the proposed treatment, risks, costs and any care needed first. Ask how your starting shade and progress will be reviewed.
Before proceeding, your dentist explains the whitening steps and tissue protection, how discomfort will be managed, and the instructions to follow afterwards.
Assessment may identify a reason to delay whitening or choose another approach. Booking an appointment does not mean you must proceed with treatment.
REALISTIC EXPECTATIONS
The degree of whitening varies with starting shade, the type of staining, tooth structure, age, previous dental treatment and individual response.
Some discolouration responds less readily than others. Whitening cannot guarantee a particular shade or an even colour where restorations are present.
Your dentist can discuss what may be achievable for your teeth. Results are not permanent; diet, tea and coffee, smoking, oral habits and maintenance can influence how long the colour change lasts.
Temporary sensitivity can occur during or after whitening. Soft-tissue irritation is also possible.
Tell your dental team about existing sensitivity or any discomfort. They can advise on appropriate management, which may include adjusting or pausing treatment and recommending suitable products.
Follow the instructions supplied. Contact the practice if discomfort persists or concerns you, rather than continuing to whiten through it.
COMPARE YOUR OPTIONS
We can discuss in-chair and take-home approaches and confirm which options are available and suitable for you. Your teeth, sensitivity, preferences and ability to follow instructions help guide the choice.
Read about at-home teeth whitening and discuss which approach is appropriate for you.
Take-home whitening may be considered after in-chair treatment for ongoing whitening or later touch-ups. Whether you need this, and how often, should be discussed with your dentist. A combined approach is not necessary for everyone, and longevity still varies.
CLEAR INFORMATION ABOUT FEES
Ask our team for the current whitening fee and an explanation of what is included before booking treatment.
Your treatment plan should set out the proposed whitening option, any take-home component, reviews and any additional dental care recommended first.
Confirm whether the assessment, cleaning, trays or gel are included or charged separately. This helps you compare the complete cost and decide whether to proceed.
ONGOING CARE
Good cleaning supports oral health. It does not guarantee that teeth will stay the same shade.
If you are considering new restorations, discuss the order of treatment before choosing their shade. Whitening may sometimes be planned first, with time for the colour to settle before final shade selection.
For concerns about shape or proportions as well as colour, learn about porcelain veneers and composite veneers. These involve different benefits, risks and maintenance and are not a routine next step simply to achieve a whiter shade.
YOUR QUESTIONS
Contact our team for the current fee and inclusions. Ask about assessment, any cleaning needed first, and whether take-home trays, gel and reviews form part of the quoted treatment.
Appointment times vary with your assessment, preparation and the clinical protocol. The team can advise how much time to allow for your visit.
Temporary sensitivity or gum irritation can occur. Tell your dentist about sensitive teeth before treatment and speak up if you feel discomfort. Treatment can be reviewed and management tailored to you.
No particular shade can be guaranteed. Your starting colour, staining, tooth structure, previous dental work and individual response all influence the result.
Whitening is not permanent. Colour may change again with diet, smoking and other individual factors. Your dentist can discuss maintenance and whether a touch-up is appropriate.
These restorations generally retain their existing colour. Natural teeth around them may lighten, creating a mismatch. Having veneers does not automatically rule out whitening other teeth, but the overall colour needs assessment.
Neither is best for everyone. In-chair treatment is carried out at the practice; take-home treatment works gradually with the supplied instructions. Suitability, sensitivity and your preferences help guide the choice.
Whitening is not suitable for everyone. Have your teeth and gums assessed first, particularly if you have pain, decay, gum concerns, cracks, sensitivity or restorations. Tell your dentist if you are pregnant or breastfeeding so they can advise about postponing elective whitening.
If you would like to know whether professional whitening is suitable for you, our team can assess your teeth, discuss the available options and explain what you can realistically expect.
