Lasers In Dentistry Part 1


Lasers used in dentistry are engineered and designed to perform special functions without changing or damaging the surrounding tissues or materials.


The functioning of a laser goes back to Albert Einstein’s quantum theory of radiation and includes other theories that help explain the local tissue damage. The first laser was demonstrated in 1960. It was ruby laser, 694nm wavelength. Interest in the medical implications of laser light was high and already in 1967 , some of the first reports appeared on the effects of very low doses of ruby light on biological tissues. In animal studies, it was observed that experimental wounds healed better if irradiated and that even the shaved fur of the experimental animals reappeared faster in the irradiated areas. There appeared to be a biological window for the dose. If too low, there was no effect, if too high there was a suprresive effect. Not much later, the Helium-Neon laser was introduced in research and the results were similar. Later on, diode lasers were introduced and they provide the same results, although some wavelengths appeared to be better for certain indications. In particular, the introduction of infrared lasers improved the optical penetration of the ligh, reaching deeper lying tissues. The first commercially available lasers in the early 80’s were extremely low powered, below 1mW was used, in spite of the fact that the first scientific reports used 25 mW. This partly explains the initial contoversy about therapeutic dosage to be used. With the rapid developement of laser diodes, the powers of therapeutic lasers have changed dramastically and diode lasers today are typically in the range of 50-500 mW. Increased power has not only shortened the treatment time but also improved the therapeutic results.

What causes sudden tooth sensitivity

Tooth sensitivity is defined as an experience of pain or discomfort that is sharp, sudden, piercing or excruciating in nature that is felt deep into the nerve endings. The pain may affect the tooth constantly or intermittently depending on its cause and nature.

Generally tooth sensitivity is caused by receding gums and enamel damage that leads to dentinal tubules in the dentine layer to be exposed and hence sensitized. Therefore, thermal sensitization like hot or cold drinks intake may make you cringe in agony. Occasionally, sweet and sour foods or even breezy cold air could also inflict sudden sensitiveness.

Zoom teeth whitening system

Zoom is a type of teeth whitening system made popular by the ABC network’s Extreme Makeover show. Zoom teeth whitening system is used to bleach teeth which are discolored, giving them a whiter appearance. It is generally done as an in-office bleaching procedure, or otherwise known as professional bleaching. In other words, this can only be done by your dentist as opposed to home teeth whitening kits due to the high concentrations of hydrogen peroxide involved and the need of extra measures to protect gums and other soft tissues.

How does the Zoom teeth whitening system work?

Teeth whitening systems such as Zoom and Britesmile, another highly popular brand, are commonly categorized under laser teeth whitening. Strictly speaking, they are actually light activated teeth whitening products where a blue-green spectrum light is utilized to catalyze bleaching reaction of tooth whitening gel applied on surfaces of teeth. The incorporation of light claims to not only activate the active ingredient, hydrogen peroxide, it also allows further penetration into tooth structure, resulting in greater bleaching capacity.

To date, there are contraindicating reports regarding the efficacy of blue light in terms of activating bleaching products. Most pointed out that there is no significant evidence supporting such need, whilst others remained positive of its vital role in enhancing bleaching results. Continue reading

As we become older, you might start to notice that you teeth start to become more yellow.

Teeth whitening are common cosmetic dental procedures with a large selection of methods such as home teeth whitening and laser teeth whitening via the popular Zoom teeth whitening system, making it highly accessible to the public.

Causes of yellow teeth and tooth discoloration

Before embarking on the journey to whiten your teeth, it is helpful to know what may be the causes behind your yellow teeth. With age, our teeth get worn out with function due to all the chewing and grinding that we put it through. This leads to the thinning of enamel, which is the hard protective layer of your teeth that gives it the white appearance. The wearing down of enamel causes it to lose its opacity and becomes more translucent. This allows the underlying dentine, which is yellow in color to show through, resulting to naturally yellow teeth. But this is not tooth staining per se, as it is a natural process. A way in which the wearing dentition can produce ‘true staining’ is when stains get incorporated into the fine crack or craze lines on our teeth, making it difficult to remove with conventional tooth brushing.
