That’s why most people opt for teeth whitening solutions to have brighter teeth and smile.

But before undergoing the treatment, it’s advisable to know the actual reason for the stained teeth. Keep reading the blog to know the top 6 common causes of tooth discoloration.

1. Poor oral routine

One of the main causes of tooth discoloration is poor oral hygiene.

Some of the poor oral habits include

  • Brushing once a day
  • Not flossing
  • Brushing improperly
  • Not rinsing the mouth after meals
  • Eating sugary food items
  • Using fluoride-free toothpaste

Improper dental routine can result in tartar build-up that can stain your teeth.

2. Inappropriate diet

The food you eat matters the most. It can have a significant impact on your dental and physical health.

Some of the food items that can stain your teeth are

  • Beverages like coffee, tea, and carbonated drinks
  • Fruits like berries, cherries, and pomegranates
  • Sweets like candies and chewing gums
  • Tomato-based sauces
  • Vegetables like beetroot and potato

Avoid or limit eating these food items for good oral health.

3. Medical issues

Some of the medical conditions can also result in tooth discoloration.

For instance,

  • Jaundice can cause enamel erosion which eventually can stain your teeth.
  • Cancer patients undergoing chemotherapy may also have yellow teeth.
  • Certain types of medications taken for asthma and blood pressure can also affect tooth color.

4. Dentin

Dentin is a brown or yellow material present under the tooth enamel.

If you have thick enamel, it will hide dentin. However, in the case of thin enamel, dentin is more likely to be visible through your teeth, thus making your teeth look yellow over time.

5. Smoking

Smoking can wreak havoc on both your physical and oral health.

The nicotine present in tobacco smoke can turn your pearly whites into yellow color in no time.

People who smoke or chew tobacco frequently can deteriorate their teeth color permanently.

6. Genes

Last but not the least, one reason you may have yellow or stained teeth is that it runs in your family.

If one of your parents has discolored teeth, good chances that you might have inherited enamel from them.

Prevention is better than cure

Follow a few tips to prevent teeth discoloration

  • Brush twice a day for at least two minutes
  • Floss daily
  • Use mouthwash after every meal
  • Cut back on smoking
  • Reduce the intake of caffeine
  • Drink an adequate amount of water
  • Avoid sugary foods and drinks
  • Visit your dentist twice a year
