The general idea of tooth whitening toothpastes is to make teeth whiter, and that can be a bit invasive. The teeth are made up of dentin and that is covered by enamel. When you continue to use abrasives on the enamel than it will wear down. It can be viewed along the same lines as a sandpaper. After you have removed the film (pellicle film) on the teeth you then go to the enamel, after that you have reached the dentin which is naturally a yellow color. After the enamel is gone, it’s gone.
If the pellicle layer remain on the teeth for many years then, because enamel s porous, some stains may work their way down into the teeth. These are harmless, but they are unattractive. This is where you will find that many people turn to whitening toothpastes to remove these deep down stains.
Whitening toothpastes will oxidize stains, and there are bleaching agents involved as well. Most will use hydrogen peroxide or carbamide peroxide. These are much cheaper than dental procedures which could run into the hundreds, but they also will take a couple off weeks to really offer results.
Many whitening toothpastes will come along with a whitening system, but they will work well on their own in due time. They are also great for ongoing whitening options.
The debate on whether or not tooth whitening is safe is ongoing. Whitening toothpastes are found to be more only a little more abrasive that regular ones. Some are more abrasive than others. Looking for the ADA seal of approval, and at the amounts of fluoride and abrasive agents that are in the toothpaste will help you to decide if it is a temporary or a permanent solution for your whitening needs.
If done in moderation, and as directed tooth whitening and whitening toothpaste=s are safe. Like any product of this nature following all instructions and reading warning labels is recommended.
Dentists want to keep patients in the seat, so some will recommend only professional treatments, naturally. However there are many good dentists that will recommend outpatient products for you to use at home. Crest is one of the most recommended dental products that had held the ADA seal the longest and has the longest reputation brand of any other.
What it comes down to is that whitening toothpastes without the system will gradually whiten the teeth deep down and not simply on the surface through bleaching agents. They also strengthen with fluoride and are almost equal in abrasiveness as a regular toothpaste.
They should be used as directed, and most have the dame recommendations as that of traditional toothpastes. It is important to brush at least twice a day, pay attention to the gum line and loss as recommended as well.
You can have a brighter, whiter smile for a fraction of what it would cost you for a professional whiting or use a whitening toothpaste in between professional cleanings. Whitening toothpastes are not substitutes for dental care, and upkeep appointments should be scheduled every 6 months to a year.
