Costs vary by treatment. At Denstudio, Harley Street, composite bonding starts from £350 per tooth, teeth whitening from £395, porcelain veneers from £1,200 per tooth (or £9,999 for 10 veneers including whitening), and Invisalign from £2,950. We offer 0% finance on all treatments and free consultations so you can explore your options without commitment.
The right treatment depends on what you want to change. Composite bonding is ideal for chips, gaps and minor discolouration — it's same-day, pain-free and fully reversible. Porcelain veneers deliver a permanent, premium result for more significant changes. Invisalign straightens teeth without wires or brackets. Teeth whitening brightens your natural shade by several tones. During a free consultation at our Harley Street practice, Dr Jana Denzel will assess your teeth and help you choose the right path.
Yes. Denstudio is located at 139 Harley Street, London W1G 6BG — the heart of London's medical district. The practice is easily accessible from Oxford Circus, Regent's Park and Bond Street Underground stations.
Look for documented clinical results (before and after photos), verifiable patient reviews, and a dentist who shows you a trial smile before any irreversible work. Dr Jana Denzel is twice awarded Young Dentist of the Year in the UK and named among the top 32 dentists globally as a Slow Dentistry ambassador. Our patients travel from across the UK and internationally to Harley Street for treatment.
Most cosmetic treatments at Denstudio are comfortable or completely pain-free. Composite bonding requires no injections and no drilling. Teeth whitening uses custom-fit trays designed to minimise sensitivity. Invisalign is smooth and gentle. Porcelain veneers involve local anaesthetic during preparation to ensure complete comfort. Sensitivity after whitening or veneer prep typically resolves within a few days.
Porcelain veneers last 15–20 years with proper care. Composite bonding lasts 5–7 years. Professional teeth whitening results last up to 3 years (with top-up gel available). Invisalign results are permanent when retainers are worn as directed. We provide comprehensive aftercare guidance with every treatment.
Absolutely — and many patients do. A popular combination is Invisalign followed by composite bonding or veneers, or teeth whitening as a finishing touch after any smile transformation. Our team will design a phased treatment plan that fits your timeline and budget.
Yes. Denstudio offers 0% interest-free finance on all cosmetic treatments, making it easier to spread the cost of your smile transformation. Ask about finance options at your free consultation.
