If you brush and floss your teeth every day, why do they still develop stains? Why can't you remove those stains at home, instead of needing a dentist to professionally clean them away? Let's take a look at three reasons why most people need professional teeth whitening to keep their pearly whites bright.
1. Modern Life Leads to Dental Staining
Many habits that seem impossible to avoid in modern life contribute to dental staining. Smoking is an obvious source of stains, which most people are able to cut back on with the help of nicotine replacement therapy, but there are many other causes as well.
Black coffee is a major cause of staining for many people, but most cannot resist the temptation of a caffeine pick-me-up during a long day at work. Switching to tea doesn't necessarily help, as both black and green tea contain tannins that can stain teeth.
Other sources of dental staining are the following delicious foods and drinks: red wine, berries, licorice, tomato-based sauces, balsamic vinegar, and cola. Giving up all these foods is probably not practical for most people, which means that it is likely that you will need professional whitening at some point even if you are careful to keep your teeth clean.
2. Stains Are Hard to Remove at Home
Once stains become established, they are very difficult to remove at home. Whitening kits contain only mild whitening agents to ensure they are safe for home use. Whitening toothpaste can be helpful for preventing stains from building up, but it has a limited effect when it comes to removing stains.
The most reliable way to get rid of stains from your teeth is to schedule a professional whitening treatment with a dentist. Dentists use high-strength bleaching agents, such as hydrogen peroxide, to weaken the chemical bonds between stains and dental enamel. In this way, they can gently strip the stains from your teeth without damaging your dental enamel.
3. Professional Teeth Whitening Gives Instant Results
If you are patient, you might be able to remove some of your dental stains using home whitening kits. However, due to the low levels of whitening agents in these kits, multiple treatments will probably be necessary, which means that you could end up spending a lot of money and many weeks or months to achieve what a dentist could in a single session. If you want a whiter smile right away, the best option is professional teeth whitening.
