Teeth can stain and discolor for a number of reasons. If you consume beverages or food that stain, your teeth can discolor over time. Smoking and chewing tobacco can also cause teeth to discolor. Some medications can cause teeth to darken as a side effect. 

Foods and beverages 

Sugar, coffee, tea, wine, berries, tomato sauce, soy sauce, and beets can all cause tooth discoloration when consumed regularly. Tobacco use can also cause teeth to stain. Some medications, such as tetracycline, can discolor the teeth as well. Discoloration can also occur naturally or with age. Regular cleanings can help prevent teeth whitening by clearing away particles that build up on the teeth and cause staining. 

Avoiding foods that can stain the teeth is the best way to prevent staining. If you consume these regularly, rinsing with water after eating can help limit their effects. Brushing your teeth twice a day with toothpaste that contains fluoride can also help. Flossing daily can also remove plaque from between the teeth and along the gum line. When combined with regular cleanings and checkups, these methods can help keep teeth clean and white.

Tobacco use 

Tobacco use causes teeth to discolor for several reasons, including the type of nicotine and the tar in tobacco products. Nicotine is colorless, but it can have a slight yellow or brown tint to it depending on the tobacco product. Tar is naturally dark in color, and when mixed with saliva, it can stain the teeth. 

Smoking cigarettes, cigars, pipes, hookahs, and other tobacco products can also cause dry mouth. Dry mouth is a risk factor for tooth decay because it can cause the oral environment to be too acidic for healthy bacteria to thrive. Without it, plaque can build up more easily and cause cavities. 

Tobacco products can also contribute to gum disease. The habit can lead to red-stained gums or even tooth loss. Gum disease can be linked to conditions such as heart disease and diabetes. Additionally, smoking decreases blood flow to the soft tissue of the mouth, which can leave the tissue more prone to infection. 

While quitting any tobacco use can be difficult, it’s well worth it for your own health and the appearance of your smile. Your dentist can provide support and advice to help you quit for good.

Some medications can cause teeth to become stained or discolored. Often, this is most noticeable on the front teeth. Some of the most common culprits include: 

• Antibiotics 

• Birth control pills 

• Antihistamines 

• Corticosteroids 

• Chemotherapy drugs 

• Oral contraceptives 

• Prescriptions for high blood pressure and heart problems 

• Sedatives 

• Tetracycline antibiotics 

The good news is that there are many things you can do to prevent your teeth from discoloring in the first place. If you aren’t sure which products are safe to use on your sensitive teeth, you can always talk to your dentist about the best oral hygiene products to use. Your dentist can also advise you about which foods and drinks to avoid to keep your smile bright.

Poor oral hygiene 

As plaque and tartar build up, the enamel on your teeth becomes stained. This discoloration can lead to yellowing or darkening of your smile. The best way to fight this source of tooth stains is to practice good oral hygiene. Brushing twice a day for two minutes each session and flossing once a day can help to remove bacteria from your mouth and prevent accumulation that could lead to teeth staining. Drinking water can also help to keep your mouth clean in between brushings. 

If your teeth are already discolored, then you may want to consider teeth whitening treatments. We may provide you with a home whitening kit or may recommend professional treatments. Either way, you can look forward to a whiter smile after treatment!
