Correcting grey or translucent teeth

When deep decay or an infection kills the pulp, the tooth no longer receives a blood supply and gradually becomes dull. Teeth that have undergone root canal treatment often develop a grey shade over time.

Certain medicines taken during childhood can stain the enamel grey or brown. Similarly, enamel development defects can make it thinner, allowing greyish or translucent dentine to show through.

Regular consumption of acidic foods and drinks attacks the enamel by gradually dissolving it. The enamel becomes increasingly thin, giving the teeth a translucent appearance. At the same time, staining substances such as coffee, tea, red wine and tobacco can mark the tooth surface and create a superficial greyish shade.

Teeth grinding (bruxism) mechanically wears down the enamel and contributes to tooth translucency. Health conditions such as gastro-oesophageal reflux or bulimia expose teeth to stomach acids, contributing to enamel erosion. Reduced saliva production caused by certain medicines or illnesses removes the mouth's natural protection against dietary acids, encouraging enamel wear. Finally, over time, metal restorations (fillings) may release ions that ‘tattoo’ the tooth from within, giving it a greyish shade.

Some deep grey shades are embedded in the structure of the tooth itself. This is often linked to taking antibiotics such as tetracyclines during childhood or to genetic abnormalities. This type of discolouration does not respond to whitening techniques either.

Treatment: To correct the appearance over the long term, the discolouration must be concealed. Ceramic dental veneers are the recommended solution. These thin, custom-made ceramic shells cover the visible surface of the tooth. Alternatively, ceramic crowns may be used for teeth that are already weakened or where the internal shade is very dark.

Translucency appears when enamel, the tooth's protective outer layer, becomes thinner or weaker. The edges of the teeth then become translucent and brittle. This wear is generally caused by acidity or bruxism.

Treatment: Treatment depends on the extent of the enamel loss. For mild wear, a thin layer of aesthetic composite can be applied in a single appointment to rebuild the tooth's surface and opacity. When wear is more extensive, ceramic veneers offer a durable solution by covering the visible surface, protecting the remaining enamel and evening out the colour.

Involuntary grinding or clenching causes widespread premature wear. The teeth become shorter, translucent and sensitive. Addressing appearance without eliminating the cause is ineffective.

Treatment: The approach has two stages. The first is to protect the teeth with a custom-made occlusal guard worn at night, which stops further wear. Once the cause is under control, the second stage repairs the aesthetic damage with composite or veneers.

After cosmetic treatment, regular follow-up is essential to ensure that the results last. Cabinet Dentaire de la Madeleine provides tailored follow-up care, including oral examinations, follow-up X-rays, personalised hygiene advice and additional treatment where needed.
