Our tooth colour is genetically determined. The '
'shape and position of the teeth also influence '
'perception; large teeth and a harmonious tooth position '
'appear "whiter". The colour impression is created by '
'light reflection, partly on the outer surface of the '
'whitish translucent (transparent) enamel, partly inside '
'the tooth at the transition to the yellowish dentin '
'
. The enamel is thicker in the area of the '
'incisal edge than at the tooth neck and is therefore '
'whiter, but also more transparent. At the neck of the '
'tooth and the transition to the gums, many teeth appear '
'somewhat "yellower" due to the dentin shining through. '
'
As we age, the enamel becomes continuously '
'thinner and the teeth consequently yellower. In '
'addition, discolouration on the teeth due to plaque, '
'food residues, lifestyle habits (coffee, tea plaque), '
'tea residues (smoking), etc.
Furthermore, '
'mineral disorders occurring during the formation of '
'tooth enamel, fluoride overdoses (e.g. dental '
'fluorosis) or deposits, e.g. as a side effect of '
'medication (e.g. antibiotics such as tetracyclines), '

lead to whitish, yellow or brown colour '
'stains
. fluorosis) or deposits, e.g. as side effects '
'of medication (e.g. antibiotics such as tetracyclines), '
'can lead to whitish, yellowish or brownish colour '
'stains, which can often also be associated with '
'structural anomalies such as grooves or stippling (e.g. '
'molar incisor hypomineralisation). Such colour deposits '
'can also be found in the dentin. Furthermore, leaking '
'fillings or crowns, for example, can cause cracks in '
'the teeth, which can promote the penetration of '
'unsightly (yellow or brown) colouring into the outer '
'tooth structures.
Traumatic haemorrhages, e.g. '
'after an accident (at least temporary blue '
'discolouration of the teeth) or brown-black dyes from '
'dead pulp (dental nerve) tissue (see above) or by '
'release from root canal filling materials can lead to '
'translucent brown-black tooth discolouration from the '
'inside of the tooth (the former pulp cavity).

White teeth without a guilty conscience
\n'
'
\n'
' Our tooth colour is genetically determined and is '
'primarily determined by the dentin inside the tooth. '
'Light reflection effects on the tooth surface and the '
'individual light transparency of the whitish enamel '
'allow the yellowish dentin to show through more or '
'less, depending on the thickness of the enamel. The '
'enamel is thinner at the neck of the tooth and '
'therefore the teeth appear more yellow there. With '
'advancing age, the thickness of the enamel layer\n'
'enamel decreases with age, which also leads to a more '
'intense yellowish tooth colour.
\n'
'
\n'
' During bleaching, the enamel prisms are roughened '
'and the tooth surface becomes porous. Less light '
'reaches the inside of the tooth\n'
'of the tooth and the tooth appears duller and whiter. '
'Over time, these changes heal again through '
'remineralisation from the saliva, which is why '
'bleaching effects only last for a period of a few weeks '
'to a few months.
\n'
'
\n'
' This is not the case when using tooth repair pastes '
'such as ApaCare '
'Repair Intensive Repair: The enamel surface\n'
'is permanently smoothened and permanently thickened by '
'depositing highly concentrated liquid enamel from the '
'repair paste (see ApaCare '
'Guide to white teeth and bleaching).
\n'
'
\n'
' This also changes the reflective behaviour of the '
'enamel towards naturally white and brighter teeth. And '
'this is permanent.

Dental plaque. What to do?
\n'
'
\n'
" If you don't brush your teeth regularly and "
'carefully, you run the risk of plaque, discolouration '
'or tartar. Other common causes of tooth discolouration, '
'which is usually dark, are the regular consumption of '
'colour-intensive foods and stimulants, such as '
'nicotine, coffee, tea, red wine, etc.
\n'
'
\n'
' Medication or mouth rinses, e.g. based on '
'chlorhexidine, can also lead to tooth discolouration if '
'taken or used regularly.\n'
'lead to tooth discolouration. This can be prevented and '
'often removed, especially in the early stages, with a '
'tooth polishing paste such as ApaCare '
'Polish.
\n'
'
ApaCare Polish '
'tooth polish is used 1-2 times a week instead of the '
'usual toothpaste and thus supplements it. This allows '
'you to continue professional teeth cleaning at home. '
'
\n'
'
Older plaque must be removed by the dentist by means '
'of professional teeth cleaning.
\n'
'
Expert tip
\n'
' Polishing pastes such as ApaCare '
'Polish complement the use of daily toothpaste and '
"are the dentist's extended arm into the home bathroom "
'after professional tooth cleaning. Polish your teeth '
'1-2 times a week.

' Apply ApaCare '
'Repair tooth repair paste in the evening after '
'brushing your teeth (e.g. with your finger or '
'toothbrush) and leave on overnight. If you want to '
'accelerate or intensify the effects, use ApaCare Repair '
'with a dental splint (ApaCare '
