How is Laser Whitening Different from Ordinary Tooth Whitening?


Laser tooth whitening is a tooth bleaching treatment that is often carried out at your dental surgery, although nowadays it’s possible to purchase a home whitening kit that includes a special light. The process uses hydrogen peroxide gel, or carbamide peroxide gel if you’re using a kit at home. The bleaching gel is a carefully painted onto the tooth surfaces before being activated with bright light. The use of a laser enables the peroxide to penetrate the tooth enamel more deeply, so bleaching is more effective. The end result should be whiter teeth than could otherwise be achieved.

If you choose to visit your dental clinic, then treatment can usually be completed in just one visit, typically taking less than an hour to complete. Your dentist or another dental professional under their supervision will apply the gel to your teeth before activating it with the light, leaving it in position for approximately 15 minutes. After this time they may rinse off the first application of gel before reapplying it to carry out the process again. This can be repeated a third time in order to help achieve the very best effects.

What Are the Advantages of Choosing Laser Whitening?
The main advantage of choosing the system is the immediate effectiveness of treatment. It does mean your teeth can be whitened during one simple appointment, and it’s even something you can probably fit in during your lunch hour. You’ll be given a checkup beforehand, and treatment will be fully supervised to make sure it’s completely safe. If necessary the strength of any bleaching gel can be adjusted to take into account additional tooth sensitivity. This type of treatment can only be carried out by a dentist or dental professional which is one of the reasons why it’s so safe and effective.

Afterwards you be given full instructions on how to treat your teeth for the first couple of days, as it’s important to avoid any highly coloured foods and drinks as your teeth will be more porous. This is due to the bleach, and it does have a slightly dehydrating effect which will initially make your teeth appear a little whiter than they really are. As your teeth rehydrate and the tooth enamel re-hardens, you’ll probably notice your teeth become slightly darker within a few days of whitening. This effect is very minor and is nothing to be concerned about. Your dentist can tell you how often you can touch up the results, but it’s usually every six months or longer depending on your lifestyle habits.

What Are the Disadvantages of Laser Tooth Whitening?
The sheer speed of treatment can also be a disadvantage as some people will benefit from having more control over tooth whitening. If this applies to you, it might be worth considering a good quality home whitening kit that doesn’t need to be activated with any special lights. It is far easier to control the results when you can see your teeth gradually brightening each day you use the system. The bleaching agents used with these kits are far less potent and are less likely to produce any unpleasant side effects such as tooth sensitivity. If you do experience any sensitivity then it’s easy just to stop whitening for one or two days until these subside.
