Let’s examine the underlying causes of tooth discoloration and what it could potentially mean for a person’s oral health and overall wellness.

Causes of Tooth Discoloration

Tooth discoloration occurs due to intrinsic or extrinsic factors [1]. Intrinsic discoloration happens when the inner structure of the tooth darkens or develops a yellow tint.

Common causes include:

• Medications. Certain antibiotics, such as tetracycline, when taken during childhood, can result in teeth discoloration.
• Dental fluorosis. Excessive fluoride exposure during early childhood can lead to white spots or streaks on the teeth.
• Injury or trauma. A physical impact can cause the tooth to darken as a result of damage to the enamel or internal bleeding.
• Aging. As people age, the enamel thins, allowing the yellowish dentin beneath to show through.

There’s also extrinsic discoloration, which affects the outer layer of the tooth. Common causes of extrinsic teeth staining include:

• Food and beverages. Coffee, tea, red wine, soy sauce, and dark berries like cherries and blackberries can stain the enamel.
• Tobacco use. Smoking or chewing tobacco is infamous for causing yellow or brownish stains on teeth.
• Poor oral hygiene. Inadequate brushing and flossing allow plaque and stain-producing substances to accumulate on the tooth surface.

Discolored Teeth and Dental Health

While tooth discoloration can be cosmetic, it can also indicate underlying dental health issues. Persistent discoloration could mean you’re not cleaning your teeth effectively, leading to plaque accumulation and potential cavities. Black or brown spots on the teeth could be a sign of tooth decay [2].

In addition, thin or worn tooth enamel often causes teeth to appear yellower and may be a sign of enamel erosion, which can lead to sensitivity and decay. If you have sensitive teeth along with discoloration, it’s time to follow up with your dentist to check your enamel health.

Managing and Preventing Discolored Teeth

In many cases, discolored teeth can be prevented. Regular dental cleanings can effectively remove extrinsic stains and help maintain white teeth [3]. Get your teeth cleaned every six months for best results.

If regular teeth cleanings aren’t enough, professional whitening treatments can restore the color of your teeth and are more effective than over-the-counter alternatives, especially for intrinsic stains. 

There’s also the option of limiting staining foods and drinks to help minimize tooth discoloration. If you smoke or chew tobacco, quitting can also help prevent further staining.

Perhaps the most important thing you can do to prevent and manage discolored teeth is to brush and floss your teeth properly. Electric toothbrushes can be effective at removing and minimizing stains. Brush twice a day and floss once daily to maintain a bright smile.

Keep Your Smile Bright and Healthy

If you notice persistent discoloration or have concerns about your oral hygiene, don’t hesitate to reach out to your dentist. Regular check-ups and professional advice are essential for maintaining a healthy, bright smile. Contact your dentist for an appointment and take proactive steps toward optimal dental health and a white smile!

Salmon and Other Fish

Salmon and other types of fish including tuna and sardines are high in vitamin D and omega-3 fatty acids, which have been shown to help reduce inflammation. Omega-3s have also been shown to help heal gum tissue in patients with periodontal (gum) disease [1].

Vitamin D supports the body with many functions, among them being keeping your teeth and alveolar bone strong, which is the bone in your jaw that supports the teeth [2]. For the highest nutrient content and benefits, choose wild-caught fish!

Spinach

All dark green leafy vegetables are excellent for oral health, and spinach is no exception. Filled with vitamin C, iron, calcium, and potassium, these nutrients are all beneficial for our smiles as well as our bodies [3]. Calcium can help strengthen tooth enamel, and vitamin C is essential for gum health! Iron helps support your body’s natural response to infections, and potassium, as we’ll soon see, is another key player in bone health!

Herbs and Spices

Herbs and spices that we add to our foods such as garlic, clove, turmeric, and ginger are anti inflammatory. For example, the active component in turmeric, called curcumin, has the potential to treat oral diseases such as gum disease and even oral cancer [4].

However, while they do have their benefits, keep in mind that these spices are pungent and some, such as turmeric, can stain teeth. Water is a great buffer when consuming foods with these healthy spices, and of course, getting regular dental cleanings can keep your teeth white!

Sweet Potatoes

The perfect fall food, sweet potatoes are loaded with vitamin A, which supports a healthy saliva production. Saliva plays an essential role in the oral cavity, and helps to balance not only oral bacteria, but the pH of the mouth as well, therefore preventing tooth decay and supporting gum health [5].

Avocados

Did you know that avocadoes have more potassium than a banana? In fact, eating a whole avocado gives you more than 20 percent of your daily potassium requirements [6].

The high potassium content of avocados makes them beneficial for oral health, as potassium works with calcium, magnesium, and vitamin D to keep your bones and teeth strong.

Avocados may even play a potential role in preventing oral cancer—plus they’re loaded with healthy fats, which can help fight the inflammation present in most diseases [7].

Do you enjoy any of these healthy foods? Adding these foods to your diet might just support systemic as well as oral health, which are, of course, connected! Next time you’re at the store, consider adding these fresh foods and helpful spices to your cart for healthy teeth and gums!
