Boutique Whitening is the UK’s most trusted whitening provider and is a professional, dentist-supervised whitening kit that uses custom-made trays to effectively and affordably lighten teeth up to 7 shades in 2-4 weeks.
Either choose to whiten teeth for 90 minutes during the day (6% hydrogen peroxide) or overnight (16% carbamide peroxide).
Enlighten Evolution is a more advanced whitening system that helps patients with deeper, more stubborn staining achieve the lightest natural tooth shade B1 (up to 16 shades) in around 3 weeks.
Week 1 uses 10% carbamide peroxide overnight, Week 2 uses 16% carbamide peroxide overnight, and Week 3 uses 6% hydrogen peroxide for 1 hour daily.
Endodontic whitening is a specialist whitening treatment designed for a single tooth that’s been treated and darkened after a root canal, trauma or internal staining.
Instead of whitening the teeth from the outside, which will be ineffective in these cases, a whitening material is placed inside the tooth to improve its shade and lighten it from within.
Our professional teeth whitening kits and brands can improve the colour of your natural teeth and are often recommended to use before cosmetic treatments like veneers or bonding. At our Lincoln dental practice, our dentists can effectively target discolouration like:
Following a consultation to assess your suitability for teeth whitening, Castle Dental in Lincoln will recommend the best kit to achieve your desired shade and help ensure a comfortable whitening experience if you have sensitive teeth.

The length of your professional teeth whitening treatment depends on the recommended system you use, your starting shade and how consistently you wear your trays. Typically:
During your consultation, our cosmetic dentists will explain which system will work best, how long it will take to achieve your desired shade, how long to wear your trays and how to use the gels safely.
Professional teeth whitening uses whitening gel placed inside custom-made trays that fit snugly over your teeth to gradually break down stains inside the tooth structure. As the trays are custom-made for your smile, the gel is more effective as it spreads more evenly and stays where it’s meant to be.
For a single dark root-treated tooth, the process is different. Endodontic whitening works from inside the tooth rather than through trays.
Before prescribing professional teeth whitening, our dentists will check your teeth and gums first to make sure whitening is suitable. This matters because whitening should not be used on untreated decay, active gum problems or teeth that are extremely sensitive or require pre-treatment.
If you are a suitable candidate, we’ll take impressions to make your custom trays, and when they arrive, we’ll ensure the perfect fit and provide you with instructions on how to use them at home.
After three or four weeks, we’ll invite you back in to check your results, sensitivity and whether any extra whitening or top-ups are needed.
| Whitening treatment | Cost |
|---|---|
| Boutique Whitening | £395 |
| Enlighten Evolution | £600 |
| Endodontic whitening | £295 |
| Top-up (1 syringe) | £28 |
Top-up kits, for one syringe, can cost as little as £28 in the future.
