Certain medications also can discolor teeth. Teeth cleaning by your dental office can often remove any external stains – and it promotes good oral health.
Be sure to visit your dentist for a thorough cleaning and examination before you decide to whiten your teeth.
You may find that a professional cleaning is all it takes to give you a whiter, brighter smile. Generally, tooth whitening is successful in at least 90 percent of patients.
As a rule of thumb, yellow-colored teeth respond well to whitening, while brownish-colored teeth don t respond as well.
Gray stains caused by smoking, taking tetracycline or fluorosis (ingestion of too much fluoride) most likely will not be dramatically changed by tooth whitening. Likewise, tooth whitening may not enhance your smile if you ve had bonding or tooth-colored fillings placed in your front teeth.
