It’s difficult to maintain white teeth if we’re being honest. It always gets to that point when brushing twice a day and using mouth rinses don’t cut it anymore. It’s also the same point where we have to turn to teeth whitening treatment. LED light teeth whitening is one of the great ways to get this done. In this article, we will learn all there is to the procedure.
LED stands for Light Emitting Diode, a device that beams off visible light when connected to electricity. They tend to be brighter and more intense than halogen or incandescent lamps albeit cooler.
In the past, UV(Ultraviolet) light was used by dentists to speed up the teeth whitening procedure. Here’s how it works: they apply the teeth whitening agent and shine UV light on the teeth to speed up the bleaching reaction. This brings better results when compared to applying the bleaching agents only. However, there is one major problem. UV light is a form of ionizing radiation, which is known to cause cell mutation. Cell mutation forms the basis of many cancers as we know them today, oral tissues being especially sensitive to UV light. Today, LED light performs the same function as UV light but without the risks of mutation.
Note that LED light acting alone cannot whiten teeth. It only potentiates the action of teeth bleaching agents. This has been proven many times by different studies. This one by the Open Dentistry Journal is of particular interest. Another advantage of LED light whitening is that it has been developed into safe and easy-to-use teeth whitening kits that can be used by anyone, anywhere. However, it must be said that professionally whitened teeth always turn out better.
During teeth whitening, your dentist will apply the bleaching agent directly to your teeth or to a mouth tray custom-made for you, which stays in place throughout treatment. Carbamide peroxide is a common agent used for this procedure. Your dentist will take special precautions to protect your gum and other sensitive mouth tissue from the effects of the treatment. After this, the LED light is applied for some time. This process is repeated .over many appointments depending on the level of discoloration.
If you’re using a home whitening kit, make sure to follow the instructions by the manufacturer. One rule of thumb is to avoid getting the bleaching agent on your gums as they can get irritated. You may also get a home whitening kit from your dentist. These work better because the whitening agents used are stronger than the ones you will get over the counter. Follow the directions given by your dentist to avoid adverse effects.
Generally, it’s advisable to consult your dentist before teeth whitening because it is not suitable for everyone. Pregnant women and young children are not allowed to undergo teeth whitening. The procedure will not work on veneers, dentures, crowns, bridges, and other forms of restorative dentistry.
This depends on your ability to maintain the new color of your teeth. You must practice good oral hygiene by brushing your teeth twice daily and flossing regularly. The use of mouthwash will help too. You also need to cut down your intake of teeth-staining foods and drinks like coffee, red wine, tomato sauce, and curries. Use a straw for acidic beverages like orange juice and sodas as this prevents direct contact with your teeth.
Lastly, go for regular check-ups as your dentist can help you keep track of your progress and detect any slip-ups early.
On average, professionally whitened teeth can last anywhere from one to three years. It all depends on the degree of tooth discoloration, the skill level of the dentist, the method used, and your ability to maintain the newly whitened teeth.
Professionally treated teeth last longer than any other type because they’re done by experts who use better methods of teeth whitening.
