Tooth-coloured caps made of porcelain or glass-ceramic, chosen for how natural they look.
What it involves
Porcelain crowns, including glass-ceramic types, can closely match the translucency and colour of natural teeth. They are widely used on front teeth where appearance matters most. They are usually less strong than zirconia.
Who it suits
Suits front teeth and teeth with moderate biting forces. Heavy grinding or clenching may favour a stronger material. The dentist chooses a material based on the position of the tooth and your bite.
How it usually works
Tooth preparation under local anaesthetic, impressions, a shade match and a temporary crown. The final crown is made, tried in, adjusted and bonded. You will usually need two visits, or one if the clinic mills crowns on site.
Risks and things to consider
Porcelain can chip or fracture under heavy biting. Preparing a tooth is irreversible and sometimes the nerve becomes inflamed. Colour match can differ between lighting conditions, particularly when only one crown sits next to natural teeth.
Questions to ask before you decide
Is porcelain the right material for this tooth, or would something stronger be safer? How will the colour be matched? What happens if I do not like the result?
