The secret of white teeth

The secret of white teeth

As you know, there is an enamel on the surface of your teeth. The color of the enamel is made by many factors: translucency, opacity, reflection, light scattering and shine of this layer. All these factors with a combination of a color of the dentin under the enamel, make the final appearance of your smile.

The dentin is darker and less transparent. Whiteness of your teeth depends on the thickness of enamel. The more enamel you have, the whiter your smile is. The thickness of enamel has genetical background. There are also other inner factors influencing the coloration of teeth.

1. Aging

Even though enamel is firmer than a bone, we can still destroy it using hard toothbrushes in combination with abrasive toothpaste. The enamel is getting thinner and the color of your teeth is getting darker. This process also comes naturally with aging.

2. Frontal teeth accident

The teeth color may often change as a consequence of an accident. It is because the blood penetrates dentin tubules. Your tooth slowly becomes non vital. Most often it appears in frontal teeth. Active people may use special teeth protectors. There are also protectors which adapt to the shape of your teeth after a short stay in hot water. This self-using type of protectors does not protect as good as one from the dentist. It is very easy. There have to be just one appointment for making impressions and your own splints are done in a few days. If you have already had an accident and your tooth has just changed its color, the best option for you is to undergo inner bleaching. In this case the surface whitening is not sufficient.

3. TTC teeth

Tetracycline antibiotics (TTC ATB) came to the pharmaceutical market in 1948. They were used as a wide-spectrum ATB in many indications for adults and also for kids. There was no information about one of the worst side effect of these drugs in that time. TTC ATBs can incorporate into tissues in the time of calcification. They have an ability to bind Na+ ions and therefore infiltrate into teeth and bones. The result is coloration of primary and secondary teeth. This coloration could range from yellow, gray, up to brown. It depends on the dose and on the length of ATB use.

4. Fluorosis

A lot of good can also make problems. For instance overuse of fluoride products in early childhood. The highest risk of formation of the fluorosis is within the first six years of age. Later, nucleuses of secondary teeth are formed, and risk of this disease significantly decreases. The level of fluorosis depends on the amount of fluorides intake, age of a child, weight, nutrition and metabolism. A lot of fluorides in the toothpaste or mouthwash for adults can cause darker color of the secondary teeth even in childhood. During the time of enamel genesis, fluorides influence its mineralization and also the future color and structure. The more fluorides you have, the worse the fluorosis can get. There can be a variety of spots from white up to brown.
