Discoloration of Teeth

All Possible Causes and Solutions


Suddenly noticing that your once bright smile is now tinted with unwelcome hues can be quite alarming. As a board-certified dentist based in New Baltimore, Michigan, with over 16 years of experience, I’ve seen numerous cases of this.

Sudden discoloration of teeth is a change in color that can range from yellow to dark brown or even black. It’s a concern for many people, and rightfully so – our smiles are often one of the first things people notice about us. This article will delve into the main types of tooth discoloration and their causes, prevention, and treatment methods.

One of the less talked about aspects of tooth discoloration is its psychological and social impact. It’s not just a cosmetic issue; it can affect self-esteem, confidence, and overall quality of life. We all want to feel good about our smile.

Extrinsic Tooth Discoloration

This refers to staining or darkening of the tooth enamel, which is the outermost layer of the tooth. Extrinsic discoloration is typically caused by:

  • Dark-colored foods and beverages like coffee, tea, wine, and berries
  • Smoking and tobacco use
  • Poor oral hygiene leads to plaque buildup

For instance, the tannins in coffee can lead to yellow stains, while tobacco use often results in brown or black stains. Poor oral hygiene allows for the buildup of plaque, which, over time, can darken the teeth.

Prevention and Treatment of Extrinsic Discoloration

To prevent and manage extrinsic tooth discoloration:

  • Brush and floss regularly to maintain good oral hygiene. Aim for at least twice a day brushing and once a day flossing.
  • Consider using whitening toothpaste or strips, which can help remove surface stains.
  • Schedule regular visits to the dentist for professional cleanings and, if necessary, professional whitening treatments.
  • Limit your intake of staining foods and drinks, or brush your teeth soon after consuming them.
  • If you use tobacco, consider quitting or at least reducing its use.

Intrinsic Tooth Discoloration

Unlike extrinsic discoloration, which affects the outer enamel, intrinsic discoloration refers to the staining or darkening of the dentin, the layer beneath the enamel. It’s often harder to treat because it’s deep within the tooth. Here are some common causes:

  • Dental trauma or injury damaging the nerve or blood vessels of the tooth
  • Aging and enamel erosion expose more of the yellowish dentin
  • Certain medications like tetracycline antibiotics, which can affect tooth development if taken during childhood
  • Diseases such as liver disease or celiac disease, which affect the metabolism or mineralization of the teeth
  • Excessive fluoride intake causes white spots or fluorosis on the enamel

For example, a tooth that has suffered trauma may turn grey or black, while certain medications can cause teeth to develop a blue or brown hue. Too much fluoride, especially in young children, can result in white spots or streaks on the teeth.

Prevention and Treatment of Intrinsic Discoloration

Addressing intrinsic tooth discoloration often requires more comprehensive measures:

  • Seek prompt dental care for any tooth injury or infection to prevent damage to the tooth’s internal structure.
  • Wear a mouthguard during sports or other activities to protect your teeth from trauma.
  • Before taking any medication that could potentially affect your teeth, consult with your doctor or dentist.
  • Regular health check-ups are essential to detect and treat any underlying conditions that might cause tooth discoloration.
  • Fluoride is beneficial for teeth, but only when used appropriately. Follow the recommended dosage.
  • When discoloration is resistant to regular whitening treatments, your dentist may recommend more advanced options like veneers, crowns, or bonding.

Remember, each case is unique, and what works for one person might not work for another. Always consult with a dental professional for personalized advice based on your specific needs and situation.

A Guide to Tooth Discoloration Colors and What They Mean

Discoloration can take on various colors, each indicative of different issues:

  • Yellow: Often results from staining foods, drinks, or smoking. This could also be due to the natural aging process where the enamel thins out, revealing more of the dentin.
  • Brown or Black: These darker stains could result from tobacco use, long-term buildup of plaque and tartar, or certain diseases and medications.
  • Gray: This could be a sign of a dead tooth or dental trauma that caused internal bleeding.

Teeth Whitening 101

If you’re bothered by discoloration, whitening could be an option for you. However, the cost and effectiveness vary greatly:

  • Over-the-counter products: These include toothpaste, strips, or gels. They’re affordable and can improve discoloration to some extent but are typically less effective than professional services.
  • Professional services: In-office bleaching offers significant and rapid improvement but tends to be more expensive.
  • Home remedies: Some people use baking soda or apple cider vinegar. While cheap, their effectiveness is debatable, and they could potentially harm your enamel.

Despite its benefits, whitening is not without potential side effects. It can lead to tooth sensitivity, gum irritation, and even enamel damage if not used properly. Always consult with a dental professional before starting a whitening regimen.

In Conclusion

Tooth discoloration is a common concern, but understanding its types, causes, and prevention methods can go a long way in maintaining a healthy, bright smile. It’s vital to keep up with good oral hygiene and regular dental visits to prevent and manage discoloration.
