What Causes Stained Teeth

• Tobacco, coffee, tea and cola stain the pigment of your teeth. Age causes the tooth's mineral structure to decrease as a person ages and makes the enamel less porous.
  
  

Foods to Whiten Teeth

• Chewing raw spinach and eating apples, strawberries and raw vegetables such as carrots, celery, cucumbers and broccoli can whiten the teeth. In addition, rubbing teeth with the inside of an orange peel (white side) will make the teeth shiny.
  
  

Lemon Juice Paste

• While calcium in the teeth is essential to stronger teeth, calcium deposits on the teeth is the major cause of teeth yellowing. A paste of 1 teaspoon of lemon juice and 1 teaspoon of salt will remove the calcium stain from the teeth and make them whiter.
  
  

Bay Leaves/Orange Peel Paste

• For quick results, rub a mixture of dried and powdered bay leaves and dried orange peel on the teeth to make them whiter.
  
  

Health Risks

• Do not use these methods more than three times per week. Acid in the lemon juice and orange peels can deteriorate tooth enamel if used too often.
  
  Also, anyone with sensitivity to acidic fruits should use caution, or consult with a doctor before use. These recipes may lead to gum inflammation or other health issues.
