Final answer:
Teeth whitening services use peroxides to remove discoloration and achieve a brighter smile. Regular dental cleanings, reducing sugar consumption, and fluoride treatment or ingesting fluoridated water are also important for oral health.
Step-by-step explanation:
Teeth whitening services offered in cosmetic dentistry offices involve the use of various chemical preparations containing peroxides. These preparations are applied to the teeth to remove discoloration and achieve a brighter smile. Alternatively, there are teeth-whitening toothpastes available that also contain peroxides. It is important to note that regular dental cleanings, reducing sugar consumption, and fluoride treatment or ingesting fluoridated water can also contribute to oral health and prevent dental caries.
