Teeth whitening plays a significant role in giving us a beautiful smile. Professional teeth whitening is becoming popular with both men and women in London and we find more and more people are taking up cosmetic dentistry treatments to improve their smile and self-confidence.

Whether you are interested in the costs of teeth whitening or would like to contrast and compare Philips and Enlighten whitening products  – we can help!

How Teeth Get Stained

To understand how teeth whitening works, we first need to understand how stains settle on to the teeth. Each tooth is composted of 3 primary layers – these are the pulp, dentin and enamel layers. Enamel is the outermost layer of the tooth and is responsible for protecting the tooth. The stains sit on this layer. Due to the intake of materials into the mouth (food and drinks) an additional layer forms on the surface of the tooth. This layer is called the pellicle film. It can be scraped away by the dentist during a cleaning appointment. The pellicle layer can often stay on the tooth for long periods of time, causing stains to penetrate and get into the enamel later. As the enamel later is porous in nature, it can absorb the staining agents and form deep stains in it. A stain can often be quite harmless, however, it can look very unpleasant and unattractive. This is what a good teeth whitening system is designed to address – to whiten your tooth’s enamel, restoring your teeth to their bright, whiter appearance.

What Causes Teeth Stains

Anything foreign that you put into your mouth can have the potential to stain your teeth and leave a mark on the enamel layer. This is the reason teeth stains can be almost non-avoidable for certain people, especially given food items and many drinks are often the main causes of stains. Some food and drinks are particularly bad when it comes to teeth stains – these include tea, coffee, soy sauce and red-wine; these drinks tend to be the biggest culprits. On average, the rule of thumb to follow is – anything that can stain your clothes or even hands will also have the potential to stain the teeth. Nicotine and tar in cigarettes and tobacco are also major causes of stains. Although nicotine is a colorless material, it acts as a staining agent the moment it comes in contact with air or oxygen. Certain medications such as some antibiotics, blood pressure medicines and anti-histamines are also known to stain teeth. Trauma to the teeth and age can also play a role in teeth staining.

What do professional dentists use to whiten teeth?

Teeth whitening works by using safe to use chemicals that enter the enamel layer of the teeth and oxidize the stains in order to break down the stains. Teeth stains are removed as a result, even the ones that have penetrated deep into the teeth. Teeth whitening comes in two forms – intrinsic whitening and extrinsic whitening. Extrinsic teeth whitening removes the stains present on the tooth enamel; the enamel layer is where common stains such as tea, coffee and tobacco stains reside on the teeth. Intrinsic teeth whitening on the other hand, lightens the softer, inner layer of the teeth. For intrinsic whitening, the cosmetic dentist uses a bleaching gel on the inner soft tissue of the tooth to whiten it. The enamel layer typically doesn’t have discoloration in this scenario and it’s the inside of the tooth that needs whitening. For either type of whitening, the various whitening systems available use either hydrogen peroxide or carbamide peroxide. For both those compounds, the final whitening agent is hydrogen peroxide as carbamide ultimately breaks down into hydrogen peroxide on use.

Teeth Whitening Options

Dentist typically offer two types of teeth whitening treatments – whitening that can be done within the surgery or whitening that can be done at home. We have provided more information on each of those methods below.

Zoom Instant In-Surgery Whitening – Whitening at the cosmetic dentist requires one visit and takes about 90 minutes to complete. You can typically have the whitening done on the day that you had your initial consultation. A dentist who whitens the teeth will first clean your teeth and then apply protective layer or barrier on your gums for protection. They will then apply a whitening gel with hydrogen peroxide (at a strength that’s much higher than home whitening treatments).

The cosmetic dentist will typically apply this whitening gel for several minutes each time. Dentists often couple the teeth whitening gel with LED light that is designed to activate the whitening agents within the gel to hasten the teeth whitening process. The dentist then rinses off the gel and then reapplies it a number of times over the course of the session. Once complete, you leave the dental surgery with brighter, whiter teeth.

At-Home Whitening – At-home whitening can be obtained from a dentist once the dentist has had a chance to assess your teeth and gums to ensure they are healthy and fit for whitening. The cosmetic dentist will take molds of your teeth and provide you with bespoke whitening trays and also a whitening gel to use at home. To whiten your teeth at home, you will add the gel to the whitening trays and use them overnight (typically) for about 2 weeks. Although this process takes longer, some patients prefer to whiten their teeth from the comfort of their own home. Home teeth whitening also provides excellent whitening results, providing brilliant white results for patients.

Teeth whitening is considered safe

side effects from the treatment

 

  • Teeth sensitivity– following teeth whitening your teeth may become more sensitive. Normally, the sensitivity will diminish with time and does not last for long unless you have a pre-existing enamel problem that needs a dental check-up. There are a number of different things you can use/do to achieve teeth whitening for sensitive teeth as well as tips for post whitening treatments which we discuss further below.
  • Irritated gums– most people generally like the in-clinic whitening for their own peace of mind and knowing that the whitening is being done right. The concentration of bleach used in the dental clinic Is higher than the at-home methods. If the bleach comes into contact you’re your gums, it can cause gum irritation. And unfortunately, the higher the concentration, the greater potential for irritation However, this side effect should go away after your treatment. Bear in mind also that dental clinics do use special protection on your gums and roots to make sure the bleach remains harmless. An at-home method can either involve a dentist-prescribed system, which allows you to use a mouth guard-style tray to hold a gel in place; or an over-the-counter (OTC) product. This type of product can take the form of toothpaste, a rinse, trays or strips. The latter two are either custom-fitted or otherwise local to your teeth’s surfaces, and may therefore be appealing to those who already suffer from gum disease.
  • And last but not least, teeth with decay, broken fillings and fractured structures can generate a more significant and lasting discomfort, but there is no damage to the enamel under these circumstances. There have been some cases suggesting bleach can affect dental amalgam – or silver fillings – causing them to release mercury.

Although many practices have chosen to discontinue this type of restoration, the Academy of General Dentistry (AGD) assures that it is not a real health issue. Not only is dental amalgam benign in its mercury content, but the bleach will not destroy other dental restorations like crowns and implants. There is also no professional concern over its effect on white colour fillings; in fact, they may slightly whiten themselves.
