Coffee, tea, red wine, smoking — and sometimes nothing more than the passing years. Tooth enamel picks up stains gradually, so most people don’t notice their smile dimming until they see an old photo. Professional whitening reverses that change, often in a single visit, and does it far more safely than the endless shelf of home remedies suggests.
Whitening strips and over-the-counter kits use low concentrations of peroxide because they have to be safe without supervision. In-clinic whitening uses professional-strength gel, activated by LED or laser light, applied by a dentist who first protects your gums and checks that your enamel is healthy enough to treat. That combination is what makes a six-to-eight-shade improvement possible in around an hour — something no pharmacy product can honestly promise.
The active ingredient breaks down the pigmented molecules trapped inside the enamel rather than scraping the surface, which is why professionally supervised whitening does not damage teeth when used correctly.
We start with a quick examination — whitening works on natural, healthy teeth, so cavities, gum irritation, or heavy tartar need to be dealt with first. Your dentist records your starting shade, isolates and protects the gums, applies the whitening gel, and activates it in cycles. Most sessions take 60 to 90 minutes including preparation. If you prefer a slower, gentler route, we can make custom-fitted take-home trays instead, which whiten gradually over one to two weeks.
Whitening isn’t permanent — new stains build the same way old ones did. Results typically hold for 6 to 12 months, longer if you go easy on staining drinks and maintain good hygiene. Many patients book a short top-up session once a year, which keeps the shade stable indefinitely.
Whitening looks simple, but the difference between a bright, even result and blotchy, sensitive teeth is clinical judgement — knowing which stains will respond, protecting the soft tissue properly, and matching gel strength to your enamel. At Dermax Medical Center your whitening is planned and supervised by dentists, not technicians, using certified professional systems. If whitening alone won’t give you the result you want — for example with internal discolouration or old restorations — we’ll tell you honestly and explain what will.

Most patients gain between four and eight shades in a single professional session, depending on the type and depth of staining. Yellow-toned stains respond best; grey tones from medication or trauma respond more slowly and may need combined approaches.
No — professionally supervised whitening does not weaken or erode enamel. The gel works on stain molecules inside the tooth rather than stripping the surface. Problems arise mainly with misused home products or treatment on unhealthy teeth, which is why we always examine first.
Some patients notice mild, temporary sensitivity for 24-48 hours. We reduce this with desensitising agents before and after treatment, and it settles on its own. If you already have sensitive teeth, tell us — we adjust the protocol accordingly.
Typically 6 to 12 months, sometimes longer. The biggest factors are coffee, tea, red wine, and smoking. Good brushing habits and an occasional top-up session keep the shade stable long term.
In-clinic whitening gives the biggest change in one visit and suits deadlines like weddings or events. Take-home trays whiten gradually over one to two weeks and suit people who prefer slower change or have mild sensitivity. Many patients combine both: a clinic session first, trays for maintenance.
