People from every corner of the world always fixate about their teeth. With the passage of time teeth of every animal get covered with a yellowish layer and especially it makes human beings so much crazy. Many people are unaware about the important things which can prevent the teeth from turning into yellowish colour. There are so many ways to get back the whiteness of teeth and achieve that sweet smile everyone wants.
The tooth is created by four different tissues. The first tissue enamel is the strong white cover which guards the tooth from regular chewing of food. Dentin the supporter which guards the enamel. It carries the nerves in the teeth which is very hard and yellow in colour. The pulp is the third tissue which stays in the centre of the tooth. It holds nerves, blood and lymph vessels. Actually, in this part of tooth the proper nourishment happens and it transfers signals to the brain. The last tissue is cementum which covers the root of the teeth and attaches the bone inside our jaw.
The main cause for yellow teeth is a layer of film develops when people eat, drink or smoke. Some film also still left over the tooth even after regular brushing. We can only stay away from this problem by brushing our teeth with a whitening toothpaste and regular consult with the dentist. However, still some film stays over their who just eats the enamel. You can say enamel is the polish of the teeth which keeps the teeth white so when the enamel fades, the dentin comes out of it and shows its yellow colour. Due to age teeth also loose its colour. It becomes dark simply with age. Regular visit to a dentist is the ultimate solution for discolouration of teeth.
We can easily trace out younger people with yellowish teeth is due to staining not from long term thinning of the enamel. Staining happens inside as well as outside of the teeth. Usually inside staining happens when teeth are developing. But the outside staining can just happen for several reasons like drinking of coffee, red wine and smoking. Soda, tea and berries have chromogenic agents which helps in developing the stain in our teeth.
There are so many ways which will help us to whiten our teeth. However, it is important to be careful about the using of products as well as the procedure for whitening of the teeth. Mostly people consult a dentist to whiten their teeth and the dentist does it. Sometimes the complete procedure for whitening of teeth may take several visit to a dentist and it costs much. Whiten strips are used to place over our teeth which contains hydrogen peroxide.
