In-Chair vs Take-Home Whitening
The two most common professional whitening options in Singapore are in-chair (in-office) whitening and take-home whitening kits prescribed by your dentist. Both use peroxide-based gels, but they differ in strength, speed, and cost.
In-Chair Whitening
In-chair whitening is performed at the dental clinic under professional supervision. A high-concentration whitening gel is applied to your teeth, sometimes activated with a special light. The entire process usually takes 60–90 minutes, and you can see results immediately — often 4–8 shades brighter in a single session.
Prices for in-chair whitening in Singapore generally range from $600 to $1,200 per session, depending on the brand of whitening system used and the clinic.
Take-Home Whitening Kits
Dentist-prescribed take-home kits involve custom-fitted trays and a lower-concentration whitening gel. You wear the trays for 30 minutes to a few hours each day over 1–3 weeks. Results are more gradual but can be just as effective over time.
Take-home whitening kits typically cost between $400 and $800 in Singapore, making them a more budget-friendly option.
What Affects the Price of Teeth Whitening?
- Type of treatment: In-chair whitening costs more due to the stronger gel and professional supervision required.
- Whitening system brand: Premium systems such as Zoom or Opalescence may carry a higher price tag.
- Number of sessions: Some patients need a second session for optimal results, especially if staining is severe.
- Pre-whitening dental cleaning: A professional scaling and polishing (from $85 before GST at Trust Dental) is recommended before whitening to remove surface stains and tartar, ensuring the gel works evenly.
- Severity of discolouration: Deeper, intrinsic stains from medications or trauma may require additional treatments.
How Long Do Whitening Results Last?
Professional teeth whitening results typically last 6 months to 2 years, depending on your habits. You can extend the longevity of your results by:
- Avoiding or reducing coffee, tea, red wine, and dark-coloured foods
- Not smoking
- Brushing twice daily and flossing regularly
- Scheduling regular dental cleanings every 6 months
- Using a dentist-approved maintenance whitening product occasionally
Who Is a Good Candidate for Teeth Whitening?
Teeth whitening works best on healthy teeth with surface or mild extrinsic staining. Good candidates include people who have:
- Yellowed or stained teeth from food, drinks, or ageing
- No untreated cavities or gum disease
- Realistic expectations about the outcome
Whitening may not be suitable if you have:
- Dental restorations (crowns, veneers, or fillings) on visible teeth — these will not change colour
- Severe intrinsic staining from tetracycline or fluorosis
- Very sensitive teeth or active gum disease
- Are pregnant or breastfeeding
Your dentist will assess your suitability during a consultation and recommend the best approach for your situation.
