10 Reasons Cause Your Teeth Discoloration - 2
Intrinsic Tooth Stains : This is when the dentin darkens or gets a yellow color. Fluorosis or tetracycline stains are examples of common intrinsic stains. Intrinsic stains are best removed through the use of high concentration whitening products that can bleach the tooth and change the natural tooth color.
7. Medications
Some medications, such as the antibiotics tetracycline and minocycline, may become incorporated into the structure of a tooth, causing intrinsic staining of the teeth with a brown-gray color. Use of tetracycline should be avoided during the period of tooth formation, from 4th month of pregnancy until 7 years of age.
8. Systemic Disorders
As alkaptonuria, erythropoietic porphyria, hyperbilirubinemia etc are also causes of stained teeth. Enamel hypoplasia causes tooth discoloration and pitting of the enamel. In rare cases, children with dentinogenesis imperfecta are born with gray, amber or purple discolorations.
9. Fluorosis
Chalky white spots or brown marks are caused by excessive fluoride intake Teeth whitening does not actually remove the white spots but lightens the background so they are less noticeable.
10. Root Canal Treatment
After root canal treatment, a tooth may start to darken, especially if the pulp chamber area is not thoroughly cleaned from dead or infected pulp tissue.
Age-Related Discoloration : Teeth change with age, their mineral structure changes becoming less porous and making teeth to appear darker. The enamel that covers the teeth gets thinner with age, allowing the underlying layer of yellowish dentin to show through.
