When it is abnormal to have Stained Teeth

Sometimes we can find stains on our teeth even if good hygiene is maintained.
This problem is aggravated by several factors. The most common causes are: Excessive consumption of certain foods (coffee, tea, red wine), Smoking, Poor dental hygiene, Taking certain antibiotics especially Tetracycline. Also, white or brown spots may appear at the initial stage of decay.
To treat stained teeth, we must first know if they are natural, otherwise, it's necessary to reveal their causes.

When Stained Teeth are normal

To know if it is normal to have colored teeth, it is necessary to understand the anatomy of the tooth. Our teeth have several layers: The outer part of the tooth consists of two layers, first the Dentine, then as an outer layer, the enamel.
Each of these layers has its own natural color. The layer of dentin being darker than that of enamel, variations in color of the teeth can appear with time.
In these situations, it is said that dental discoloration is normal:
  • Our enamel wears out with time. Being clearer and more transparent, it gives a glimpse of the dentin which is more yellowish.
    In addition, dentin tends to become darker over time, so it's normal to see our teeth color change over time.
    The change in staining of the dentition usually affects all teeth, but may affect a single tooth under conditions where it was overloaded.
  • Dental staining can respond to genetic factors such as people with dark skin have lighter teeth.
    We are not all born with white teeth. The color of our teeth is related to the color of our skin or our gums. It depends on the amount of malanine secreted by our body.
    So the color of our teeth can be determined by genetic factors, specifically heredity.
The solutions are either to accept the color of our teeth as they are or to whiten them at a dentist.
Before starting a teeth whitening, It's important to know that treatment is not recommended in the presence of cavities or active gum disease.
A check of the teeth will be necessary to examine the degree of wear. The dentist remains the only person who can diagnose the presence of such conditions in your mouth and measure the impact of these conditions on the success of tooth whitening.
Teeth whitening will be performed using a whitening agent. It will act directly on the surface of your tooth (the enamel). But also on the dentine (which is under the enamel).

When stained teeth are abnormal

Dental stains become abnormal if they suddenly appear as a result of some of the factors listed below or if the stain grows over time due to prolonged exposure of the tooth to the causal factor.
The presence of stains on the teeth surfaces have several causes. If the stain has appeared as a result of any of these factors, it means that the stain is not normal and needs to be treated.
Among these factors:
  • The consumption of certain foods: such as Coffee, Tea, Red wine, Fried foods and Curry.
    Other highly pigmented foods: cherries, soy sauce...can cause stains on teeth.
  • Cigarettes: Cigarettes cause significant staining of teeth.
  • Some drugs: Many drugs, including antibiotics, may be responsible for stains on the teeth.
  • fluorosis Exposure of teeth to high doses of fluoride: Represents a big risk for people who lives in regions where fluoride exists in significant quantities in soils, water and air.
    The excess of fluoride can alter the enamel and cause Fluorosis.
  • Early stage Cavity: White or brown stains can appear at the initial stage of decay.
    The stains mean the demineralization of the enamel because of the acidity. So, do not confuse them with other types of dental stains.
    The treatment is localized to enamel surface associated with fluoridated prescription to prevent its reapparition to the other healthy teeth.
  • Traumatism: During a trauma, the pulp is reached too. The blood which is an essential component of the pulp will coagulate and appear as a stain on the tooth.
  • Poor oral hygiene: Teeth Brushing associated with the use of a Dental Floss, Mouthwash and a Water Jet if necessary prevent the appearance of teeth stains.
Solutions to reduce the appearance of teeth stains are: Reduction of consumption of pigmented foods, Reduction of smoking, the use of appropriate hygiene products and remove some bad habits.
You can use baking soda regularly by sprinkling your toothpaste. The ideal is not to use it every day. 2 or 3 times a week is enough.
Lemon is also effective, thanks to its acidity that helps restore whiteness to stained and yellowed teeth. It also reduces tartar and offers fresh breath. Vitamin C present in the lemon is favorble for the gum.
However, the permanent contact of acidity with the tooth destroys the enamel. It's advisable never to brush your teeth with lemon juice more than twice a week.
