The buildup of the tartar and calculus also can increase teeth staining which is why a dental cleaning is always recommended first. The restoration of natural tooth shade may be achieved through having the teeth cleaned in the dental office which is also called polishing and scaling. The tartar and calculus can be removed easily with the help of the professional dental cleaning.

Tooth discoloration and tooth staining

The teeth can turn dark if there is too much build up on its surface and this will hide natural tooth color or the tooth itself can discolor which is called intrinsic staining.

Extrinsic discoloration

The extrinsic stains may be internalized because of cracks or enamel defects. It can also be the results of the dentine which is exposed to extrinsic stains which is deposited in or on dental pellicle. The cause of the extrinsic staining may include:

  • Dental plaque: even if it is not visible when it is at the tooth surface, the plaque can be stained through chromogenic bacteria like actinomyces species.
  • Calculus or tartar: if there is neglected plaque, it can calcify afterwards and it can lead on the formation of the hard deposit at the teeth and mostly on the gumline. The calculus color may vary and it can be brown, black, yellow or grey.
  • Tobacco: tobacco products produce tar and it is also found in the smokeless tobacco. The tar tends to form yellow, black or brown stains on the neck of a tooth, just over the gumline.
  • Chewing of betel
  • Some drinks and foods such as vegetables and other food products are rich in the xanthonoids and carotenoids which stain the teeth. The liquids that are colored such as red wine, tea, coffee and cola also can cause the discoloration.
  • Some medication such as antiseptic mouthwash will bind to the tannins which mean that it can stain the teeth with a prolonged use.

Intrinsic discoloration

When there is a change in thickness of the dental hard tissue, it may result in the intrinsic discoloration. Some factors behind this problem, they may act systematically or locally and it can affect single tooth and all the teeth which may lead to the discoloration like a result. There are different diseases which had been known to affect developing dentition, mostly during the enamel or dentin formation and it may lead to the discoloration. This may cause the intrinsic staining.

The causes behind the intrinsic staining are:

  • Fluorosis
  • Hperemia
  • Enamel hypoplasia
  • Dental trauma
  • Dental caries
  • Amelogenesis imperfecta
  • Dentinogenesis imperfecta
  • Minocycline and tetracycline
  • Alkaptonuria
