Get a naturally bright smile – safely and professionally

Professional teeth whitening in Dún Laoghaire

If you have healthy teeth and gums, but yellowed staining is letting your smile down, come and speak to us about professional teeth whitening in Dún Laoghaire. Teeth become stained for lots of reasons – and while coffee, tea and red wine are the obvious culprits, so too is the simple fact of ageing, and sometimes genetics. Whitening is like resetting the clock on your smile. You’ll not only look instantly better and feel more confident, but you’ll be more likely to look after that smile with a robust oral hygiene routine, which will lower your risk of gum disease and tooth decay. It’s a win-win situation!

The safe route to a healthy smile

Whatever the cause of your stained smile, the best way to deal with it is to book a consultation at Killane Dental Care. We’ll assess your suitability for professional teeth bleaching, and can offer higher-strength, prescription-only, bespoke whitening kits that you use at home over two weeks. We use the renowned Pola whitening system, which can be adapted to take into consideration the strength of bleach you require and the time you have available to wear the trays. You’ll need to sit for dental impressions, which are used by a dental lab to create bespoke bleaching trays that sit over your teeth perfectly, targeting your prescription bleaching gel effectively without it touching your gums. After around two weeks, your whitening course will be complete and you’ll be able to enjoy your sparkling new smile!

Is teeth whitening suitable for everyone?

Almost. There are a few patients for whom whitening may not be advisable, which is why it’s imperative to only have teeth whitening after being approved by a qualified dental professional.

Why get my teeth whitened at the dentist?

The dentist is your only option if you want your whitening to work and you want it to be safe. Unlike over-the-counter or online products, professional whitening means the dentist can prescribe the highest-strength bleaching agent for you, yet adjust it if it causes any problems. This means you’ll get the best possible results with the least discomfort.

How do I get started with teeth whitening?

If whitening is the right treatment for you, we will take your dental impressions, which will be sent to a lab where your custom-fit bleaching trays will be manufactured. Unlike generic bleaching trays, lab-made trays exactly fit the contours of your gum line, protecting your gums and targeting your teeth more accurately.

Can you whiten crowns, bridges or veneers?

No, whitening gel only works on natural teeth – so if you are having dental restorations such as crowns and bridges, or veneers, make sure you talk to your dentist about whitening too. It’s recommended that whitening is carried out first so that restorations can be colour-matched to your newly white teeth.

How long does teeth whitening last?

The more you look after your teeth, the longer the effects of whitening will last. Whitening is like resetting the clock on the colour of your teeth – so they will start to darken again with age and to collect stains again, just as they would if you’d never had them whitened. After whitening, be mindful about what you eat and drink, avoiding the foods and drinks that stain teeth, and step up your dental hygiene routine. You can also use your bespoke whitening trays for top-up treatments in future at Killane Dental Care.

The best dentist I’ve been to. And I’ve been to plenty 🙂


Amazing dentist. Very understanding, made me feel at ease at all times.


I have attended with family members on several occasions and I am very happy with the treatment received from Dr Killane. He's a lovely man and is very professional and caring.

Dr. Robert had operating hours that could accommodate me, so I went to him for a check-up and a filling. I’m not sure I saw a price beforehand, but I was quoted at the appointment. Everything went well and I didn’t need to go back for any follow-ups.


Killane Dental is a lovely, tastefully decorated clinic. Everyone – including the receptionist – was really friendly. I’ve no complaints about my experience.
