Teeth yellowing can be caused by a host of factors. From a dental-orthodontic viewpoint, it is most often caused by two main factors:
- The gradual thinning of enamel over time
- The thickening of the layer underneath, known as the dentin.
Along with a host of other, external factors that may or may not be in your control.
Tooth discoloration can range from affecting the entire color of the tooth or just random spots and lines. Environmental factors such as certain foods and drinks medications and overall oral hygiene can all have an effect on increasingly yellowed teeth as well.
As the enamel thins out over time, the natural yellow-brown color of the dentin emerges from underneath more prominently. The yellowing may be more or less obvious depending on other factors such as genetics. In addition, once the dentin becomes exposed, other coloring agents become more easily absorbed into the teeth, making the problem worse.
Keep these three tips in mind for optimal oral health:
- Braces: The discoloration of teeth is one of the main fears those that brace wearers have. Due to the way braces lay on the teeth, without proper care, overall discoloration can occur and be seen when they are removed. Be sure to be extra vigilant of oral care if you wear braces or orthodontic gear.
- Food and drinks: Excessive consumption of sugars, acids and alcohol can cause tooth discoloration as well. Be aware of what you're eating and when it's time to brush or floss again.
- General health: A person's general health can also affect the color of teeth. Constant dry mouth, or suffering from a disease such as bulimia or acid reflux, can also play a role.
