Professional Teeth Whitening in Harold Wood, Romford

Why choose professional whitening?

• Stronger, dentist-only gels for noticeably brighter results

• Custom-fitted trays for even, comfortable whitening

• Choose day or overnight treatment, whichever fits your routine

• Supervised by a dental professional — safe for gums and enamel

• Longer-lasting than shop-bought strips and kits

Your whitening options

Not every case needs the same approach — we'll recommend which type, or combination, suits you at your consultation:

• At-home tray whitening — custom-fitted trays with dentist-grade Philips Zoom gel, worn as a day treatment (60–90 minutes) or overnight, whichever fits your routine.

• Selective (intense) whitening — targets specific teeth that are more heavily stained or slower to lighten, rather than treating the whole arch.

• Internal whitening — for a single darkened tooth, usually after root canal treatment, where gel is placed inside the tooth itself rather than just on the surface.

What to expect during treatment

Most patients whiten over 4–6 weeks, though it's common to take short breaks if teeth feel sensitive, which can extend this to two or three months — there's no rush, and you're always in control of the pace. Mild to moderate sensitivity is normal, as is teeth whitening at slightly different rates from one another. Worth knowing beforehand: whitening only lightens natural enamel, so any existing fillings, crowns or bonding won't change colour and can look slightly darker by comparison — many patients choose to refresh these afterwards with composite bonding. We'll usually see you for a review around 8 weeks in, and you're welcome to get in touch sooner if anything doesn't feel right.

Getting the best results

For a couple of weeks either side of treatment, it helps to go easy on strongly-coloured food and drink — coffee, tea, red wine, curry, soy sauce and beetroot — along with smoking, vaping and acidic or fizzy drinks; these won't stop the whitening working, but can affect the surface finish. If you do feel sensitive, sensitive toothpaste (such as Sensodyne or Colgate Sensitive Pro-Relief) placed in your trays overnight can help, and you can always pause for a few days and pick back up when you're ready.

How much does teeth whitening cost in Romford?

At-home Philips Zoom whitening starts from £375, with intense and in-surgery options up to £750 for stubborn discolouration. We'll confirm the right option at a short consultation — whitening pairs beautifully with hygiene treatment, or as the finishing touch before bonding or veneers.

Whitening FAQs

Is teeth whitening safe?

Yes, when supervised by a dental professional. By UK law, whitening must be carried out or prescribed by a registered dentist — which protects your teeth and gums.

How long do results last?

Results are long-lasting for most people — a top-up usually isn't needed, though many patients choose one anywhere from two to five years later to keep their smile at its brightest.

Will whitening work on crowns or veneers?

Whitening only lightens natural tooth enamel, not existing crowns, veneers or bonding — we'll plan around any restorations, and can refresh them afterwards if needed.

What's the difference between standard, selective and internal whitening?

Standard (at-home) whitening treats your whole smile using custom trays. Selective, or intense, whitening targets specific teeth that need extra lightening. Internal whitening treats a single darkened tooth from the inside, usually after root canal treatment. We'll recommend the right option, or combination, at your consultation.

Can I pause if my teeth feel sensitive?

Yes — sensitivity is normal and you're always in control. You can shorten wear time, take a few days off, or use a sensitive toothpaste in your trays, and pick back up whenever you're ready.
