Dental crowns

When a tooth needs covering rather than filling.

A crown caps the whole tooth and takes the chewing load off it. It is what stands between a cracked or root-treated back tooth and an extraction.

When one is needed

01

After a root canal

A root-treated back tooth is brittle and splits under load. A crown is not optional afterwards; it is what makes the root canal worth having.

02

A cracked tooth

A crown holds a cracked tooth together. Left alone, cracks propagate, and they tend to end below the gum.

03

A tooth that is mostly filling

Once the remaining walls are thin, another filling will not hold and will eventually take a wall with it.

Materials

01

All-ceramic

Zirconia or lithium disilicate. Strong, tooth-coloured, no dark metal line at the gum. The default for most teeth now.

02

Porcelain fused to metal

An older option, still useful in some situations, but it can show a grey line at the gum as the gum recedes.

03

Gold

Still the kindest material to the opposing tooth and the longest-lasting on a molar, if the appearance does not bother you.

Questions

Asked often.

How many visits?

Usually two, a fortnight or so apart, with a temporary crown in between.

Will it look like a tooth?

An all-ceramic crown matched in daylight is difficult to pick out. Front teeth are harder than back ones because of translucency, and we take more time over them.

How long will it last?

Many years, and often far longer. What ends a crown is usually decay at its margin or gum disease underneath, not the crown itself — which is why cleanings matter more after one, not less.

My temporary came off.

It happens. Keep it, call us, and avoid chewing on that side. Do not use household glue.
