Teeth Whitening Advice


Do you like the idea of having whiter teeth but not sure how to make it happen?

FIRST, we must start with the law.

On 31 October 2012, the EU Council Directive 2011/84/EU came into force in the UK. It sets out who can use what strength of product when carrying out tooth whitening.

In the UK, the changes were brought into force by the European Communities (Cosmetic Products) Regulations 2004 to 2013.

The Regulations say that products containing or releasing up to 6% hydrogen peroxide can be used, as long as:

  • Products of this strength are sold only to dental practitioners.
  • A dentist has first examined the patient to make sure there are no risks or any other concerns about their oral condition.
  • The patient is over 18 years old.
  • For each cycle of use, the first use is by a dental practitioner or under their direct supervision by a dental hygienist or dental therapist.

Over-the-counter products

  • Tooth-whitening products and kits bought over the counter on the internet can legally only contain up to 0.1 percent hydrogen peroxide.
  • This concentration is too low to have any noticeable effect on the colour of the teeth.
  • Products that contain over 0.1 percent hydrogen peroxide can legally only be sold to a dentist.

Who cannot provide tooth whitening?

  • The General Dental Council takes the view that applying materials and carrying out procedures designed to improve the appearance of the teeth amounts to ‘the practice of dentistry.
  • This decision confirmed that tooth whitening can only be provided by a qualified and registered dentist, dental hygienist, or dental therapist working to the prescription of a dentist.


How to Proceed?

We do understand that having it carried out by a dentist will cost more than looking online or maybe if you see a beauty shop performing treatments? But it is vital to say that it is not safe to buy and use unlicensed products.

At Boundary Implant Centre we offer two choices of whitening.


  • Opalescence Go,


This is a prefilled whitening tray process providing professional strength teeth whitening with unrivaled convenience.


The dentist prescribes the kit to you and guides you on how to use it, then we review you after 10 days.


The kit comes with 10 pre- filled trays in one box, you take it home and wear the trays top and bottom for up to 90 minutes a day.


Top-ups are then required as and when you feel like you need to.


  • Custom made.

This process involves more visits.

To begin the dentists must take impressions of your teeth to make custom-made trays for you to wear.

You then return 1 week later to have the trays fitted and your whitening gel prescribed.

You inject your gel into the trays yourself and wear them (normally overnight) for up to 10 days.


Where whitening is carried out, each case sees a different result. It is vital to say that you cannot whiten crowns, implants, or bridges and if you have any white fillings on the front of the teeth these may need to be changed.

Option one is the more affordable route, from £200.

Option two may be needed if the teeth are crowded.
