Causes and Treatments for Dental Fluorosis

Dental fluorosis is the condition of poor appearance and health of teeth due to excessive intake of fluoride during the developmental period of teeth. This mainly happens in the form of tooth discoloration with enamel mottling, ranging from mild white spots to severe brownish staining. As this particularly occurs during childhood, when teeth are under formation, it is caused by the ingestion of an abnormally large amount of fluoride from several sources.

Causes of Dental Fluorosis

Ingestion of fluoride is the most common cause of dental fluorosis during tooth formation. This can occur in various ways, such as: 

1. Fluoridated Water: Drinking water that contains concentrated levels of fluoride, mainly in areas where the natural water contains fluoride or has been added to the water supply in order to promote good teeth and bones.
2. Dietary Supplements: High intakes of fluoride supplements or fluoride-containing foods, drinks like tea, certain seafood.
3. Dental Products: High consumption of huge amounts of fluoride toothpaste or mouth rinses; more so in children who have yet to learn how to spit out the toothpaste from their mouths.
4. Environmental Exposure: Inhalation and accidental ingestion of industrial fluorinated pollutants and pesticides.

Symptoms and Diagnosis

Various signs and symptoms associated with dental fluorosis include mildly noticeable white streaks on teeth, which at a severe stage manifest as brown discoloration and pitting. It is usually diagnosed by a dentist after he has examined your teeth, and undoubtedly, he will most probably ask you questions relating to fluoride exposure history.

Treatment Options

1. Mild Cases: In mild cases, treatment would not be required as the stains are very faint and do not cause any threat to the health of teeth.
2. Whitening Treatments: Aesthetics of teeth with moderate fluorosis can be improved by whitening treatments performed by professionals.
3. Bonding or Veneers: Bonding or veneers may be done to the stain in such severe cases of fluorosis to give it a uniform look.
4. Prevention: Of all, prevention is of the utmost importance, especially for children, by checking the intake of fluoride coming from all sources. Also, the correct amount of fluoride toothpaste and mouthwash should be used by children and they should be supervised by an adult.

Conclusion

Dental fluorosis is a condition where exposure to excess fluoride occurs during the years of tooth development, leading to discoloration, mottling, and staining of teeth. While monitoring fluoride intake is an ideal measure to avoid the problem, treatment options vary depending upon the severity of the condition. Most people, if armed with some knowledge of the causes and treatments, could quite independently avoid or even manage dental fluorosis and its effects on their oral health and smile aesthetics. If you think you or your child has fluorosis, start by seeing your dentist for a checkup. He or she can assess your situation and then come up with a treatment plan.
