Brown or white stains on teeth

Poor oral hygiene
A lack of regular brushing leads to a build-up of dental plaque, which traps pigments and causes stains.

Smoking
The nicotine and tar in cigarettes penetrate the enamel, causing persistent discolouration that is difficult to remove.

Fluorosis and dental erosion
Dental fluorosis is caused by excess fluoride. It appears as white or brown spots on the enamel. This condition is often caused by excessive use of fluoride toothpastes and mouthwashes, or by drinking water with too much fluoride. The teeth can then become more vulnerable to decay and wear.

Molar-incisor hypomineralisation (MIH)
This mineralisation defect causes white, yellowish or brown marks and makes the teeth more sensitive.

Ageing enamel
As we age, the enamel gradually becomes thinner, revealing more of the naturally darker dentine beneath.

Medication
Certain antibiotics, such as tetracyclines given during childhood, can cause irreversible grey or brown pigmentation.

The acidity of lemon and the abrasiveness of activated charcoal are often promoted for their whitening properties. However, lemon can erode enamel, making the teeth more vulnerable, while activated charcoal can damage enamel because of its abrasiveness. The healthcare professionals at Cabinet Dentaire de la Madeleine recommend avoiding these methods and choosing professional treatments that protect and strengthen oral health.

A highly effective whitening agent commonly used in professional treatments. At home, it may be used as a diluted mouth rinse or mixed with toothpaste. It works by breaking down the molecules responsible for stains and discolouration. However, incorrect use of hydrogen peroxide, particularly at too high a concentration, can cause gum irritation, increased sensitivity and even enamel damage.

An ancient Ayurvedic practice that involves rinsing the mouth with oil, usually coconut oil, for about five minutes. The technique is said to ‘draw’ toxins and bacteria out of the mouth, helping prevent gum disease and remove plaque, which is often responsible for dental staining. Although oil pulling may benefit oral health, it is not a substitute for professional dental care. The healthcare professionals at Cabinet Dentaire de la Madeleine emphasise that this method alone will not whiten teeth effectively.
