Professional teeth whitening remains one of the most popular cosmetic dental treatments, and for good reason. It’s relatively quick, non-invasive, and can make a noticeable difference to how your smile looks.
At Diggers Rest Dental House, we offer both in-chair and take-home whitening options. Which one suits you depends on your timeline, sensitivity levels, and how much whitening you’re after. Here’s what you need to know before booking.
In-Chair vs Take-Home: The Real Differences
Both options use professional-strength whitening agents, but they work differently.
In-chair whitening:
- Takes 60-90 minutes in a single appointment
- Uses higher-concentration gel with light activation
- Results visible immediately
- Ideal if you want quick results for an event
Take-home kits:
- Custom-fitted trays made from impressions of your teeth
- Lower-concentration gel worn for 1-2 hours daily
- Full results in 2-4 weeks
- Better for gradual whitening or sensitive teeth
Some patients combine both: in-chair for immediate impact, then take-home trays for maintenance.
Here’s What Whitening Can (and Can’t) Do
Whitening works brilliantly on extrinsic stains, the surface discolouration from coffee, tea, red wine, and everyday life. Most people see their teeth lighten several shades.
What whitening handles well:
- Coffee and tea stains
- Red wine discolouration
- General yellowing from age
- Tobacco staining
What whitening can’t fix:
- Intrinsic stains (discolouration inside the tooth)
- Tetracycline staining from childhood antibiotics
- Existing crowns, veneers, or fillings (these don’t whiten)
- Grey discolouration from trauma
During your consultation, we’ll assess your staining type and let you know what results to realistically expect. If whitening isn’t suitable, we can discuss alternatives like veneers.
The Sensitivity Question
Temporary sensitivity is the most common side effect of teeth whitening. It typically lasts 24-48 hours after treatment and responds well to sensitive toothpaste.
We take several steps to minimise discomfort:
- Applying protective barriers to your gums
- Using desensitising agents before and after treatment
- Adjusting concentration levels for sensitive teeth
- Recommending take-home options for patients prone to sensitivity
If you’ve experienced sensitivity with whitening before, let us know. We can adjust our approach accordingly.
How Long Do Results Last?
Professional whitening typically lasts 6 months to 2 years, depending on your habits. Coffee drinkers and red wine enthusiasts will notice fading sooner than those who avoid staining foods.
To extend your results:
- Use a straw for staining drinks
- Rinse with water after coffee or wine
- Maintain regular brushing and flossing
- Consider periodic touch-ups with take-home trays
We can supply top-up gel for your custom trays, making maintenance straightforward.
What Happens During Your Appointment
For in-chair whitening, here’s the process:
- We check your teeth and gums are healthy enough for whitening
- We photograph your current shade for comparison
- We apply protective barriers to your gums and lips
- We apply the whitening gel in several rounds
- We rinse and reveal your results
The whole appointment takes about 90 minutes. You’ll leave with noticeably whiter teeth and instructions for maintaining your results.
Payment Options
We accept all major health funds with HICAPS for on-the-spot claims. Payment plans through Afterpay and Humm are also available if you’d prefer to spread the cost.
