Which teeth whitening system is best?
At some point in our lives we notice our teeth have discoloured and we desire to have a sparkling white smile to radiate health, happiness and confidence again. But how do you decide between doing it yourself at home or professionally at the dental office?
Dr Linda advises that the first thing, is to have a dental exam to make sure your discoloration is not due to a condition in need of treatment. Your dentist is the best person to advise which technique would be the most effective whitening method for your particular situation. They will discuss the risk and benefits of each method and advise accordingly.
What is the difference between the two techiniques?
Professional in office teeth whitening involves the use of high-concentration whitening gels that are not available over the counter. as they would be less safe or less predictable if used at home. Your dentist will apply a gel to your teeth and leave it on for about an hour. A heat or light source may be used during the process to increase the bleaching action.
Take-home whitening involves custom made mouth trays made of thin, flexible plastic that you fill with a small amount of whitening gel and then leave on your teeth for a prescribed period of time.
What are the Risks of Teeth Whitening?
The main risk is tooth sensitivity following bleaching and that varies with a given product’s concentration and the amount of time it is left on the teeth. If sensitivity does occur, it usually lasts no more than one to four days. Gums can also become irritated on contact with bleaching solutions. Its important to wipe off excess gel from your gums during whitening and to inform your dentist of any problems.
How long do the results last?
No matter which whitening system you choose, the results tend to fade over time. The results can last anywhere from six months to two years, though longer-lasting results have been reported.
