Guide to Teeth Whitening Costs in North Finchley (N12)

Professional teeth whitening helps when staining from coffee, tea, red wine, or smoking makes your smile look dull. It also suits aging teeth that have naturally yellowed. Consider this treatment for a special event like a wedding or when you want a confidence boost from a refreshed smile. A healthy mouth with gums in good shape is a sign you may be a good candidate for cosmetic whitening. Unlike over the counter options, professional care is supervised by a dentist for safety and effective results.

Your whitening journey starts with a 30 minute initial check at our Finchley practice to review your dental health and confirm you are suitable. Next we take impressions to make custom whitening trays that fit you precisely. About a week later you return for a 20 minute visit to collect your trays and professional gel. We show you how to apply the gel. Then you wear the trays at home for a few hours daily or overnight for roughly 2 to 3 weeks to reach your desired shade. A final follow-up checks your satisfaction with the results.

Professional take‑home whitening at our practice typically costs between £350 and £500. The price covers your initial check, the custom trays, the whitening gel, and all follow-up visits. There are no hidden fees. A recent North Finchley patient asked for a bright smile before her wedding; her package, including trays and gel, came to £425. Since whitening is cosmetic, it is not covered by dental insurance plans. We can provide a detailed quote during your consultation.

Right after whitening and during the 2 to 3 week treatment period you may notice some temporary tooth sensitivity. It usually fades within 48 hours. To ease it, use toothpaste for sensitive teeth. We advise avoiding strongly coloured foods and drinks like coffee, red wine, and curries for the first 48 hours after each whitening session to prevent re staining. To keep results long term, maintain good oral hygiene and consider occasional top‑ups, perhaps once a year, for which you can buy extra gel from us. If sensitivity is severe or lasts longer, call during office hours.

Professional whitening is highly effective, but other options exist. If staining comes from internal tooth issues or you have restorations, veneers or composite bonding may be better because they mask deep stains and match shades precisely. For minor surface staining, a thorough hygiene appointment can sometimes lift stains and restore brightness. Whitening toothpastes offer little change and can be abrasive, so they are not a true substitute for significant shade improvement. We will discuss the best choice for your smile during your consultation.

To make an informed choice, ask any provider these questions, whether it is us or another practice in North London: What percentage of hydrogen peroxide is in the whitening gel? UK law allows up to 6 percent when prescribed by a dentist. How long can I expect my results to last? Do you create custom fitted trays or are they one size fits all? What are the options if I experience significant sensitivity? Does the quoted price include top up gel or is that extra? This helps you understand safety, effectiveness, and the full cost of treatment.
