Why Our Teeth Turn Yellow
Your smile has a very huge impact on your physical appearance and stained teeth is one thing you least expect to appear from your smile. Stained teeth can cause embarrassment, affecting your child’s self-esteem and confidence. It can ruin first impressions because of its unsightly appearance.
Understanding the cause of teeth staining can help improve dental hygiene practice and oral care habits.
Two Types of Tooth Stains
1. Extrinsic Stains. This stain appears on the tooth surface. It can be removed through professional polishing or scaling. Stains can be due to food dye, beverages, mouth rinse and the presence of colour-producing bacteria (chromogenic bacteria) and poor dental hygiene. Plaque bacteria (biofilm) on tooth surface absorb these stains and accumulate on teeth.
2. Intrinsic Stains. This type of stain is seen inside the tooth and can’t be removed by professional cleaning. There are several reasons why a stain develops inside the tooth. Antibiotic use, particularly tetracycline; infection, trauma and dental fluorosis or excessive ingestion of fluoride, which can weaken the enamel and cause brown spots on the teeth, are the leading causes of intrinsic stains.
Different Stain Color and Their Sources
The sources of stain can be determined by the color, and the patient’s lifestyle, diet, environmental and dental hygiene. This helps identify the most effective solution to manage and remove staining.
