Why teeth discolored

Research by Sagel and others have shown that some stain particles remain on the tooth enamel, while others work through the tooth enamel over time and set beneath the tooth surface, which creates dullness and tooth stain. Tooth color is subjective, and it can be hard to tell how well teeth-whitening products are working to remove or reduce teeth stains.

A study in the Journal of Dentistry showed that even professionals disagree on tooth color when evaluating the same teeth, and a single professional can rate the whiteness of the same tooth differently on different occasions.

A dentist may also perform minor procedures to whiten the teeth and protect them from further decay.

These include bleaching and applying topical fluoride. Tooth discoloration associated with celiac disease is permanent. Most stains and spots caused by fluorosis or tooth decay are likewise irreversible.

For permanent or stubborn brown spots on the teeth a dentist may be able to hide discolorations, or prevent further discoloration, with:. Some foods can help to strengthen enamel and prevent discoloration. Those rich in roughage or fiber can help to scrub bacteria and bits of plaque off the teeth.
