1. Making dietary changes
Eliminating foods that mark the teeth can prevent further staining. Foods and beverages that contain tannins, such as wine and tea, can stain the teeth. Coffee, dark sodas, and juices can also stain them.
Acidic foods can make the teeth look yellow by wearing down the enamel. People who are concerned about the color of their teeth should avoid the excessive consumption of citrus, coffee, and soda. Alternatively, they should always brush their teeth after having them.
Dentists generally recommend waiting at least 30 minutes after eating before brushing the teeth. Acids can weaken the enamel, so brushing too soon can cause damage.
Quitting smoking or tobacco products can reduce the risk of nicotine stains. It can also prevent tooth decay and gum disease, both of which can damage the enamel and cause oral health issues.
2. Trying oil pulling
Oil pulling is the term for washing the mouth with oil to remove dirt, bacteria, and debris. It is not a substitute for regular brushing or flossing, but some research suggests that washing the mouth with certain oils may help to whiten the teeth.
The American Dental Association (ADA) considers oil pulling to be unconventional dentistry, stating, “there are no reliable scientific studies to show that oil pulling reduces cavities, whitens teeth, or improves oral health and well-being.”
However, to try this method, rinse the mouth with oil for about 20 minutes after brushing, then spit it out.
Oils suitable for oil pulling include:
coconut oil
sunflower oil
sesame oil
3. Brushing with baking soda
Baking soda can gently polish away stains on the surface of the teeth. Some people worry that baking soda is too harsh and may grind away enamel, but research from 2017 found it to be a safe way to remove stains.
Baking soda may also help to fight bacteria, which suggests that it may be able to reduce plaque and prevent tooth decay.
