Stains that are inside your tooth enamel are called intrinsic stains. Intrinsic staining is sometimes present even before your teeth erupt from your gums when you’re a kid. These stains can result from antibiotic use, high levels of fluoride exposure, and your tooth enamel growing thinner as you age.
Extrinsic stains are on the outside of your tooth. These happen due to environmental exposure to things that leave discoloration on your tooth enamel. Coffee, artificial food colorings, and smoking can all cause this type of staining.
Access to teeth whitening treatment may also depend on your budget. Whitening products and in-office treatments are generally not covered by insurance. Some people may choose options that have a milder whitening effect but are more affordable, like toothpastes and mouthwashes.
People who have dental implants or veneers are not candidates for teeth whitening. Teeth whitening works on natural teeth only. Many younger people in recent years have pursued veneers to achieve a perfectly white smile, but this can be dangerous for your teeth’s health in the long run.
If you are self-conscious about your smile because of teeth yellowing and you have your natural teeth, you might want to try teeth whitening methods. But ultimately this is a personal aesthetic choice and not a medical necessity.
Consult with your dentist about what whitening options may be best for you. Always read directions on home kits and use products as directed.
It’s important to note that people with dental implants, veneers, crowns, or bridges might not be candidates for teeth whitening, depending on the location of this dental work. If it is in the back of the mouth, a person may still receive whitening. If it is in the front of the mouth, whitening is not recommended.
The length of time you can expect tooth whitening to last is based upon the type of whitener you’re using. Your lifestyle habits also have an effect.
Tooth whitening treatments are designed to reduce stains, not repel them. If you have good oral habits and keep your teeth clean, at-home products and dental procedures will last longer.
If you maintain good oral hygiene, a chairside (or in-office) procedure should provide long-lasting results for 1 to 3 years. This procedure is done in your dentist’s office. It usually requires only one visit. This procedure uses a strong bleaching agent, such as highly-concentrated hydrogen peroxide or carbamide peroxide. Heat or light may also be used, to further accelerate the bleaching agent.
If you enjoy these regularly, make sure to brush, floss, and rinse often.
Chewing on sugar-free gum, parsley, or mint can also help clean your mouth by stimulating the flow of saliva.
