For a brighter smile, professional whitening is a well-evidenced, non-invasive first step. Practices in Grendon Underwood tailor the concentration to your natural shade rather than a one-size-fits-all gel. Results can appear in a single in-chair session or build gradually over two to three weeks at home.
Managing Sensitivity After Whitening
Sensitivity is the most common side effect — usually a sharp, transient twinge with air or cold that settles within 24–48 hours. A sensitivity toothpaste used for two weeks beforehand noticeably reduces it.
A brief 'white diet' — skipping strongly coloured food and drink for two days — protects the fresh result. Long-term, good hygiene and an occasional top-up every 12–18 months keep teeth bright.
Professional Whitening Choices in Grendon Underwood
In-chair (laser/light-activated) whitening is done at the practice in one 60–90 minute appointment. A high-concentration gel is applied and activated with a light or laser, giving immediate results — typically a 4–8 shade lift, depending on your starting point.
Take-home tray whitening uses custom trays and professional-strength gel worn daily (30 minutes to overnight) over 2–4 weeks. It builds a gradual result with less sensitivity than in-chair treatment.
Combined whitening blends both approaches: immediate lift in the chair, then home trays to fine-tune and sustain the colour.
Over-the-counter kits sold in shops are limited by law to weak gel concentrations, so they're fine for touch-ups but no substitute for dentist-led whitening.
