Complete Smiles is a leading teeth whitening clinic in Harrow that offers both Philips Home Whitening Kits as well as Philips In-surgery Whitening Treatments.

The safest way to whiten teeth is by using gel prescribed by a dental professional. Whitening products that you can buy outside of your dentist only contain 0.1% Hydrogen Peroxide and very little active ingredients to whiten your teeth. Some products don’t contain any whitening ingredients but instead harmful ingredients such as lemon juice, citric acid and bicarbonate soda to dissolve stains which can damage the enamel. Therefore, ask one of our dentists about Teeth Whitening and we will be more than happy to explain the various options available.

If you wish to choose home teeth whitening procedure, then the dentist will take an impression of your teeth to make a mouthguard. Using your mouthguard at home, you regularly apply the gel for a specified period of time over 2 to 6 weeks.

We use Philips Zoom as our in-surgery teeth whitening option. It’s a light-activated technology for powerful whitening, unlike many other systems, Philips Zoom uses a proprietary LED light to accelerate whitening for maximum results in minimal time. This is administered by one of our dentists, so you know it’s the best, healthiest option for your teeth. In clinic whitening takes about an hour depending on the patient’s needs.

How Does Teeth Whitening Work?

During your visit to your dentist for teeth whitening your dentist will apply a thin layer of whitening gel to your teeth. The Zoom light and whitening gel penetrate the tooth to remove stains and discoloration. Your dentist will use a blue LED light 3 times throughout the 45 minute treatment, that will shine on the teeth and speed up the process. After treatment a post-treatment gel is applied to reduce sensitivity and protect the enamel.
If you choose to do teeth whitening at home, your dentist will take an impression of your teeth and a mouthguard will be made. Then, using your mouthguard at home, you regularly apply the gel for a specified period of time over 2 to 6 weeks.

What is Philips Zoom?

We choose to use Philips Zoom at Complete Smiles because it delivers exceptional results and is long-lasting. The treatment time is 45-60 minutes and involves us using a whitening gel and a special LED accelerator. The results can be teeth that are up to 6x lighter than their original shade. The treatment is also suitable for patients with sensitive teeth.

Is teeth whitening permanent?

Teeth whitening is a temporary fix. It can last anywhere from 3 months up to 3 years and it differs for everyone, but smoking cigarettes or drinking red wine, tea or coffee will cause stains that negate the effects of teeth whitening in no time flat. Unfortunately teeth whitening doesn’t work on dentures, crowns, fillings or veneers.

Before After

The difference you’ll notice before and after your teeth whitening should be very pleasing. You’ll love showing off that pearly white smile!

Teeth Whitening

We always recommend using our dentist for instant teeth whitening, even if you choose to do the treatment at home. Some home kits or salons do not have the right kits or trained staff and could cause damage to your gums and cause sensitive teeth.

Teeth Whitening FAQs

Professional dental products used under the guidance of a professional dentist do not damage the teeth or gums. Some sensitivity may occur after the whitening process; however this can be easily treated with non-invasive gels.

Teeth whitening methods work by oxidising the teeth. Oxygen molecules from the bleaching gel interact with bright molecules trapped in the base, causing them to separate and produce whitening of the teeth.

Our dentists would be happy to discuss the different ways to whiten your teeth to help achieve the Complete Smile you have been looking for!

Undoubtedly, the answer to this question is "yes", Please ignore some of the widely thought of Myths .... "Teeth whitening strips a layer of your tooth" "Teeth whitening ruins your teeth" "Teeth whitening damages the enamel" Studies have shown no significant long-term effects associated with home-based treatments containing 10%, 16% carbamide peroxide or 6% hydrogen peroxide. As a dentist, it is our job and responsibility to make sure you have healthy teeth that are suitable for whitening and that the procedure is done safely. Be aware of the illegal dental whitening services offered in the UK and the many non-certified online products for sale. These can cause painful and permanent damage to the teeth, lips and gums. In the UK, safe, effective, and long-lasting dental safety can be set up for you by a qualified dentist.

There are major points to consider; 1. Safety 2. Success Safety - As already mentioned, illegal dental hygiene is still rampant, and a combination of improper dental implants, leaky trays and impurities containing harmful acids and harmful particles poses a serious risk. The legal limit for Hydrogen Peroxide (an agent used to whiten teeth) that dentists can apply in the UK is 6%. Regulations here limit the amount of Hydrogen Peroxide to as much as 0.1% on any item off the shelf. This is 6000 times weaker than professional whitening and has little effect on long-term whitening of the teeth. Beware of "whitewashing brushes" many of these are harmful and may remove some of the stains but will also remove the enamel over time. Effectiveness - Many internet-based providers use a variety of whitening and UV lamps. Unfortunately, the reality of these programs is that all they do is dehydrate your teeth so that for a while (48 hours high) they will look a little whiter. There is a big question about their safety and the long-term damage they do to teeth and gums. How do I start professional teeth whitening at Complete Smiles? Your health and safety is very important to us at Complete Smiles. After conducting a thorough medical examination of your teeth and gums, we will address your options of using dental whitening technology. We will take a closer look at the current colour of your teeth and talk about how you can achieve the desired shade. Even more important is the consideration of dental work you have had in the past. If you have had crowns, veneers, bridges, or a composite bonding, it should be considered how you can keep your smile as pleasing to the eye as possible, as composite materials will not change colour with just any type of teeth whitening. An Initial Consultation with one of our dentists will lead to creating a bespoke treatment plan suitable for you. Click here to schedule your consultation and take the first steps to a bright white smile.

The most important thing to define with your dentist is - why are your teeth sensitive? In many patients, sensitivity can be treated before considering dental whitening. Dental whitening can create a slight and temporary sensitivity, but your dentist will be able to guide you through a routine that allows even people with sensitive teeth to get a white smile. Just because you have sensitive teeth doesn't mean you can't whiten your teeth.

The result of teeth whitening is less likely to last longer if you smoke often or regularly consume products that can stain your teeth. These substances can cause external decay (stains) that reduce the brightness of your teeth. However, that does not mean you cannot brush them. With good preparation, regular visits to the dental hygienist to remove any stains and by following the advice given by the dentist, you should be able to continue your diet as usual.

NO! There is no evidence that any of these products whiten your teeth. Bicarbonate soda is a very versatile ingredient and has almost endless uses from cleaning and kitchen cooking to removing stubborn carpet stains and odours. It can do a good job of lifting stains of red wine or coffee from the surface of your teeth, as will charcoal toothpaste, but it is rough, so they can wear your teeth.

No, never. Because you whiten your teeth little by little at night and at home, when you get to the shade, you are happy with you can stop - you can control it. Your dentist will discuss with you the results you are trying to achieve, but for most people, we try to compare the shade of your teeth with the white shade of your eyes.
