Let’s talk teeth whitening – what exactly is it, is it bad for our teeth and what’s the difference between going to a dentist as opposed to a beauty salon for the treatment?

What exactly is teeth whitening?
When asked -“what would you like to improve most about your smile?” The most common response from people was whiter & brighter teeth – this is where teeth whitening comes in.
Teeth whitening is the process of brightening the colour of your natural teeth, removing stains and discoloration.




Above patient Brian (33 years) was unhappy with the shape and colour of his teeth. After discussing various options including Orthodontics, we decided to do a course of tooth whitening followed by cosmetic bonding of his front teeth to change their shape.

Treatment: Tooth Whitening followed by Cosmetic Tooth Bonding.

Duration of treatment:  Slow-release whitening followed by one visit in the chair for Cosmetic Bonding.

What happens during the treatment process?
The process is relatively simple, involving just a few steps. Firstly, your teeth and gums are checked to ensure that you are dentally fit and a good candidate for whitening. Then impressions are taken, and a custom-made tray that fits exactly to your mouth will be fabricated. Once the trays fit properly, you will be showed how to use the whitening gel, which is placed in the tray and worn through the night as you sleep. The trays are extremely thin and comfortable to wear, people rarely have any problems sleeping with them.

Is everybody suitable?
Most people are suitable candidates for whitening. However, if you have existing crowns/veneers/fillings on your front teeth- due to the material are unable to whiten.

How long do the teeth whitening effects last?
Teeth whitening results are long-term, but not permanent. People who smoke, or expose their teeth to foods and drinks that cause staining will see the whiteness fade more quickly than those who don’t. Once your whitening trays are made, they can be reused, and it is a simple and inexpensive process to “top-up” from time to time. We recommend topping-up one night every second month to maintain optimum whiteness.

How “white” will my teeth go?
This depends on a number of factors and results will vary between patients. Our system will get your teeth to as white as they will naturally go. Check through our smiles gallery to see some of our patient’s results.

How soon will I see results?
You will see results within a few days – just in time for Christmas!

Is it going to damage my teeth for the future?
Absolutely not- studies of teeth whitening products using Carbamide peroxide showed little to no effect on the hardness or mineral content of a tooth’s enamel surface- this is the

Are there any side effects?
Between 10-20% of people who whiten their teeth experience sensitivity, either during the night when whitening, or the following day. This sensitivity is transient, and normally goes away within 24 hours. Using sensitive toothpastes, or special desensitising gels available from Portobello Dental Clinic will normally alleviate the sensitivity.

It’s cheaper in a Beauty Salon – I’ll just go there…
It’s cheaper for a reason- beauticians cannot check your teeth for decay/defective restorations, they will not be able to diagnose gingivitis nor periodontal disease. They are also unqualified to administer and monitor teeth whitening products.
Dentists are bound by codes of practices including cross infection control measures that are often not in place in such commercial whitening businesses.
The only saving grace is the commercial whitening clinics/beauty salons cannot get access to the same professional strength teeth whitening systems as the dentists (obviously the dental companies only issue their high strength product to Irish & UK registered Dentists). So there is an element of damage limitation, in so far as, the product doesn’t actually work particularly well. The percentages of hydrogen peroxide that commercial whitening businesses/beauty salons can get access to is so low that there is no chance of these whitening products actually working to the same degree as dentist delivered teeth whitening.

It’s been said time and time again- but sometimes spending slightly more now will save you in the long run.

The days may be dingy but there’s no need for your smile to match. If your teeth are looking a little stained or discoloured these days then why not think about finishing off the year with teeth whitening in Dublin? Having your teeth whitened by your dentist in Dublin is the safest and easiest way to do it, as Portobello Dental Clinic will only provide you with professionally made whitening trays and whitening gel if we know this treatment is right and safe for your teeth.

Whitening Isn’t Right for Everyone

Teeth Whitening DublinThis is the reason why your dentist in Dublin will need to check your teeth and gums beforehand as it’s essential you don’t have any existing dental diseases such as tooth decay or gum disease. If you do then these will need treating before you can proceed with your treatment. The reason for this is that otherwise the bleaching gel will penetrate your teeth and gums in these damaged areas, and could cause unwanted sensitivity or possibly even pain. We can also assess whether or not this treatment will work well for your teeth. For instance if you have any existing porcelain restorations such as crowns or veneers or composite resin fillings you need to be aware that whitening will not change their colour. This means you will either risk ending up with teeth of varying shades, or that you may need to budget to have these restorations replaced.

Teeth bleaching in Dublin will not work well on teeth that have internal stains. For example, it is not likely to help lift stains caused by antibiotics, or dental fluorosis, a condition caused by excess exposure to fluoride as a child. You also tend to get better results from teeth that are yellow coloured rather than grey.

The system we use is extremely safe and is designed to gently whiten your teeth over a period of one or two weeks. We provide you with custom-made dental trays that fit exactly over your teeth so the whitening gel cannot leak out. We will give you full instructions on how much gel to use, and you should find the trays are comfortable to wear overnight. Some people do experience tooth sensitivity after whitening their teeth, and this is because the treatment makes the teeth slightly more porous immediately afterwards, increasing sensitivity towards hot and cold foods. It can help to use toothpaste designed for sensitive teeth, or we can suggest some products that may be useful. In any case, the effects should quickly go away.

One of the advantages of using this type of system is that the results are highly controllable as you will see your teeth gradually becoming whiter over a matter of just a few days. This system allows you to control the level of whitening you’d like, but it’s always important to be realistic about your chosen tooth colour. For the best and most natural results you should never try to whiten your teeth beyond the colour of the whites of your eyes.

If you do need to replace any restorations then it’s best to do so after whitening as this will enable us to accurately match the colour of the porcelain to the shade of your newly whitened teeth.

Are you looking to get a whiter smile in time for the holiday season? If so there might still just about be time but you’ll need to contact us as soon as possible. Otherwise you can look forward to starting off the New Year with teeth whitening in Dublin.



Treatment : N did not like her irregular front teeth and there were old and unsightly white fillings in two of them

We discussed all the treatment options including porcelain crowns, veneers and cosmetic bonding. We felt that cosmetic bonding would be best because :
a) it is possible to do in a single appointment,
b) reduced cost compared to other treatments,
c) although not quite as cosmetic as porcelain veneers, it is still possible to get a very good aesthetic result.
The teeth were whitened over a two week course, then reshaped using cosmetic re-contouring techniques and repaired using cosmetic bonding.

Treatment carried out by: Dr Nicholas Beirne

Treatment time: Whitening over 2 weeks, followed by cosmetic bonding in a single appointment

Cost of treatment: €740


The overwhelming evidence about the safety and effectiveness of tooth whitening products favours the use of hydrogen peroxide, typically carbamide peroxide at between 10-16% strength. This is only licensed for use in Ireland by dentists, and cannot be bought in the shops or beauty salons.  As a result of a recent EU ruling, any use of products which contain high levels of peroxide (>18% carbamide peroxide or equivalent) is now illegal. This means that “Laser bleaching”, or one-hour “power whitening” are no longer available.

Whitening toothpastes work only to remove surface staining and will not change the underlying colour of the tooth.

It has always been our belief at Portobello Dental Clinic, that “take-home kits”, with a well made custom fitting tray, designed and fabricated to fit exactly to the patient’s mouth and using 10-16% carbamide peroxide are the most effective method of whitening. One hour of whitening is simply not enough time to get a good result.


Our advice about tooth whitening:

1.      Ask for the product used and its concentration

2.      Only go to regulated professionals, i.e. dentists

3.     If in doubt ask for the Dental Council Registration Number

4.      If a light is being used ask why – it has no effect

5.      Any concerns: contact the Irish Medicines Board

So why whiten teeth?
Tooth whitening is an excellent treatment, and very often the first treatment of choice in cosmetic dentistry. I have met patients who thought that they needed 10 or more veneers to brighten their smile (a very extensive treatment plan); but after I encouraged them to try teeth whitening first, the results were so good that they no longer needed the veneers.

Tooth whitening is:

  • * Inexpensive
  • * Conservative (non-destructive) – tooth enamel is not removed
  • * Whitened teeth never look fake – real teeth still look real – just brighter and cleaner
  • * No permanent side effects, although a TEMPORARY sensitivity during the process is not unusual.

Who is suitable?
Most adults are suitable for tooth whitening, but yellow discolouration responds better than grey. If you have crowns, veneers or white fillings then they will NOT change colour and may look yellow beside your newly whitened teeth. Your dentist will be able to discuss this with you before your treatment.

How white can the teeth go?
This varies from person to person but everyone will see a difference. Some people’s teeth can take longer than others to reach the final shade and not everyone will achieve the same end shade, as this depends on the individual’s teeth. However, the majority of people will see a very significant change.

How long does the new colour last?
The new colour will last for many years, but it is also dependent on oral hygiene and how much tea, coffee, red wine and other richly coloured food and drink is consumed. Most people will typically top up the treatment to maintain the colour by wearing the trays for a few hours every 6 months or so.

What if you have only one dark tooth?
Often, it is possible to bleach a tooth from the inside if it the only one that has discoloured (typically after a root canal). Again this is a very conservative treatment – you may not need that crown after all!

How does it work?
There are essentially two main types of long-term whitening:

  1. In surgery bleaching, where a high concentration of bleach is applied to the teeth by the dentist for a short time (1-2 hours). In my experience this bleaching is only effective when combined with the custom tray kits worn at night time (option 2 below), otherwise the results fade within a few weeks.
  2. Take home kits using custom made trays which fit exactly to the shape of your mouth and hold the whitening gel against your teeth for a longer exposure time (6-8 hours a night for 2 or more weeks). This is what I recommend for the majority of my patients.

So which method is best?
We find that find the “at home” treatment more predictable, less uncomfortable, gives better and longer lasting results. As the whitening gel is in contact with the teeth for a longer time overall deeper, more thorough whitening is achieved. 

What about the kits you can buy over the internet or in the chemist?
There are a few things to consider here here. Most importantly, the tray used to hold the bleach should be custom-made to your mouth and fit exactly; if it is not tight and allows the bleach to leak, then results will be poor and you will most likely just ingest the whitening gel..
The active ingredient used in our kits is 10-15% carbamide peroxide (equivalent to 3-5% hydrogen peroxide). Most whitening products bought over the counter such as toothpastes and whitening strips contain just 0.1% hydrogen peroxide.
Some unlicensed internet distributors supply bleaching products that are too acidic, which can permanently strip your enamel. You should always use a reputable professional when considering cosmetic dentistry – dental enamel NEVER grows back.

Will I get the same result from whitening toothpastes ?
No. Only professional whitening will give you noticeable results. Some toothpastes may remove a little more staining than others but none will significantly change the colour of your natural tooth structure.

Top tips:

  • Visit your dentist for a comprehensive check of all of your teeth and gums before undertaking whitening. He/she will also be able to give you an indication of how suitable you are for the treatment.
  • Make sure you are using whitening trays that are custom made to fit your mouth
  • If teeth become sensitive during whitening, using smaller amounts of gel or lowering the gel strength (to 10%) will decrease sensitivity
  • You can also use sensitive toothpastes, or wear your tray for a few minutes in the morning with the sensitive toothpaste in it. Rarely people suffer a lot of sensitivity during whitening, and in these cases we can prescribe an additional desensitising gel.
