Teeth Whitening.

Results vary significantly. Most patients lighten by 3 to 8 shades. Yellow tones whiten well; grey tones less predictably. Existing fillings, crowns and veneers don't whiten, sometimes we replace these afterwards to match the new shade.

Some sensitivity to cold during whitening is common, usually transient, fading within a day or two of stopping. We can adjust the gel strength, recommend desensitising toothpaste, or take rest days if it's significant.

Professionally-prescribed whitening gel used as directed is well-tolerated and doesn't damage enamel. The risk is more around overuse, excessive concentration, or whitening on damaged teeth, which is why we assess first.

Custom trays hold the gel exactly where it needs to be, don't slip, don't irritate the gums, and use a stronger gel safely. Over-the-counter strips can work but results are less predictable and less even.

Most patients hold their result for 12 to 24 months with occasional top-ups. Coffee, tea, red wine, smoking and curry pigments will all gradually pull the colour back over time.

Yes, always whiten first if you're planning new front-tooth work. Crowns and veneers are made to match your current shade, so it's important to settle on the colour you want before they're made.
