Randhawa Dentistry offers professional take-home tooth whitening using custom-fitted trays and prescription-strength whitening gel — a clinically proven method that delivers gradual, even results with minimal sensitivity. Unlike over-the-counter strips, the custom trays ensure the gel contacts every surface of the tooth evenly, and the concentration of active ingredient is calibrated to your starting shade and sensitivity level. Most patients achieve a noticeably brighter result within two to three weeks of nightly use.

Whitening gel only acts on natural tooth enamel — it has no effect on porcelain, ceramic, or composite restorations. If you have crowns, veneers, or bonding on visible teeth, whitening your natural teeth may create a shade mismatch. The dentist will assess your existing restorations before recommending whitening and advise you on realistic outcomes.
Results typically last between one and two years, depending on your diet and lifestyle habits — regular consumption of tea, coffee, red wine, and tobacco will accelerate re-staining. Because you keep your custom trays, top-up treatments using a small amount of additional gel are straightforward and significantly more affordable than starting from scratch.
Professional tooth whitening carried out under dental supervision is considered safe for the vast majority of patients. The dentist will check for any contraindications — such as active decay, cracked teeth, or severe sensitivity — before prescribing the gel. Temporary sensitivity during treatment is common but resolves within a day or two of pausing use.
