Does it hurt

Does laser teeth whitening hurt?

Not anymore. But many people are still not aware of new advancements in teeth whitening treatments which mean that it’s now possible to whiten teeth in 1 hour without the dreaded post treatment sensitivity. The reason for this is the introduction of peroxide free or ZERO peroxide teeth whitening systems. These new treatments do not use any peroxide but instead a substitute most commonly sodium perborate, Sodium perborate (PBS) is a white, odorless, water-soluble chemical compound with the chemical composition NaBO3.

Is it as good as the painful peroxide whitening of the old days?

Some people think they have to suffer to have a whiter smile, but in a survey which appeared on The Consumer Show on RTE (it used to be on the TV years back), a panel of consumers compared results of peroxide and peroxide free teeth whitening – that’s what we use at Dublin Vitality Centre – and found that the results were comparable. All consumers agreed that no sensitivity was experienced during their peroxide free treatment. What this means is that there is no need to suffer unnecessary sensitivity for excellent teeth whitening results. Not at Dublin Vitality Centre anyway.

How Does 1 Hour Laser Teeth Whitening Work?

The PBS gel is applied to the teeth by a dental clinician and a laser light is applied over it to activate it. The gel is changed at 12 – 20 minute intervals. Usually, there are 3 of these timed minute sessions meaning that the treatment takes approximately 1 hour. The laser light used is a cold filtered laser which means that no heat is applied, thereby avoiding any damage to the soft tissue or enamel.

Is non peroxide teeth whitening as good as peroxide based whitening?

Yes, and it’s better for your teeth too. For years, teeth whitening was a throw off between high levels of sensitivity or a brighter, whiter smile. In the past, many people suffered temporary sensitivity after their teeth whitening treatment as their teeth would became sensitive to hot and cold temperatures through exposure to peroxide. They wanted to achieve the crowning glory that everyone desires – a brilliant beautiful set of white teeth. Even though the sensitivity was generally only temporary lasting up to 48 hours for most people and a simple analgesic would suffice to kill the pain, people didn’t like the sensation. Then came non peroxide and with it good news. These newer treatments achieve the same teeth whitening results for many people and cause no sensitivity at all, even for those with sensitive teeth.

What caused the teeth whitening sensitivity of old days gone by?

What caused such high levels of sensitivity in the teeth was peroxide or hydrogen peroxide, commonly known as bleach. In Europe, before October 2012, many dentists used levels of peroxide as high as 35% which is 6 times the legal percentage to whiten teeth. The recommended maximum use of peroxide for teeth whitening is 6%. With very high levels of peroxide, the patient would feel some temporary sensitivity during and after treatment.
In October 2012, European laws changed to help regulate the use of peroxide by dentists and teeth whitening clinics. The reason for this was because of the amount of patients who reported sensitivity post teeth whitening treatment. This is good news for everyone. It means that anyone can achieve a perfect white smile and remove stains which build up over time such as nicotine, caffeine, red wine and dark foods. It means that the maximum percentage of peroxide a dentist can supply is 6% and it means the introduction of newer treatments containing no peroxide at all. A white smile can give the patient a new lease of confidence as they feel good about showing off their new set of sparkling teeth.
