There is a large variety of over the counter teeth whitening supplies available that are both effective and cheap. Results from most of these treatments can be seen within two to three days and will probably keep teeth white for a period of up to 2 months depending on the lifestyle of the patient and especially the amount of dark fluid intake per day as this is what causes the worst discoloration of teeth in all cases. These treatments all have side effects but are neglected as the side effects are either easily dispersed off or don't affect the patient for years to come. Not all treatments are certified by the American Dental Association as whiteners that work. Patients should steer clear of treatments that are not certified as these products may carry severe consequences and side effects. The side effects of such treatments may end up being irreversible staining of the gums and cheeks or rotting teeth as well as the loss of taste and numbness of cheeks and lips.

The teeth whitening supplies that are available and certified by the ADA, can often be the same used in certain dental practices for in-office treatments. Not all the different types are used or even recommended by dentists as some are not as effective due to the list of ingredients which in some cases could be harmful to the soft tissue in the mouth surrounding the teeth. The treatments that do work should usually contain either a high or low concentration of either hydrogen or carbamide peroxide as these is the only agents that can actually bleach teeth and anything else should be considered dangerous. Some in-office treatments that do work can also have the same side effects as over the counter goods, maybe not for the same length of time or to the same extent. Some in-office treatments that really work are gel bleaching with teeth whitening trays which is very effective but you still might have to come back for more. Laser whitening is also an option as it caries the same side effects of a sore mouth, lips and gumline due to the process. The side effects don't last as long as those of gel treatments but hurts more initially.

Generally teeth whitening supplies are available over the counter at any pharmacy or some even from the shelf in supermarket. The treatments that are available in supermarkets may include toothpaste which is only effective when used continuously forever and could take months to start showing any results. Mouthwashes are also being advertised as whitening agents and also carry the necessary agents but are just as effective as the toothpaste and take a while to show results. The more intense options include a whitening strip or bleaching strips as wall as whitening gel's which contains either hydrogen peroxide or carbamide peroxide as a bleaching agent. The oxidizing agents of the peroxide, penetrates the pores of the teeth, which means it reaches underneath the surface of the teeth and bleaches the internal stain deposits instead of harming the surface of the tooth. Eventually the peroxide will have spread through the entire tooth which means the entire surface is whitened.

When purchasing teeth whitening supplies, the patient's dental history as well as allergic history should be studied first as the neglect of this could lead to catastrophic teeth and you will have to replace them with plastic ones. If a patient has any sort of filling or prior repair to teeth done, a dentist should be consulted. The reason for this is that the oxidizing agent in peroxide causes the filling to disperse or loosen leaving sensitive areas of the tooth unprotected and vulnerable. Should the peroxide come into contact with such sensitive teeth, the pain will be unbearable and eventually the tooth might rot and break even further.

The teeth whitening supplies used in dental practices and are also available over the counter also include the gel process but there is no need to purchase a tray as the dentist will keep it as future reference to the patient's teeth as well as using it for further whitening or future treatment of the patient. Other treatments include, bleaching pen, bleaching by laser or a light cured protective layer over the surface of the teeth which involves placing a thin layer of composite material over the teeth which is dried with a light. This method is effective for covering or disguising the discolored teeth. Another good treatment for covering or disguising discolored tooth are porcelain veneers which is a thin layer of porcelain that is paste onto the surface of the teeth. This treatment is also very effective for hiding skew or uneven teeth. The laser treatment however is the most expensive and most effective as it costs about a thousand dollars for one treatment but the treatment which usually takes up to four hours or longer depending on the degree of discoloration, will leave teeth whiter than it initially was and it lasts for up to four months depending on the patient's lifestyle.

Teeth whitening supplies are not very expensive as even the most expensive treatments will only cost up to a hundred dollars depending on the type of product that is used. Patients who suffer from sensitive teeth should not intend to whiten their teeth with a home whitening kit as this could leave teeth decaying and could cause severe pain to the gums and mouth as well as some cases of diarrhea. The teeth whitening process is a process which leads to irritation of the gums, cheeks and tongue as the gel dissolves with saliva in the mouth. This leaves a foul taste as well as irritation which can in the long term cause mouth or throat cancer. Although all product brands would disagree, tests have shown that irritation to the gumline and cheeks leads to cancer. This means that it's not the product that is dangerous but the treatment itself. Select your teeth whitening supplies with care.
