In immediate answer is that, where a filling is insufficient, a crown is required.
A crown is needed when the tooth has decayed to such an extent that the tooth itself is not strong enough to hold a filling.
Therefore, your dentist clears away the decay, shapes the remaining parts of the tooth and then the crown is quite literally placed over the top.
Therefore, in terms of procedures, it is quite a leap from a filling to crown.
A filling is quite often a relatively quick procedure that can be completed in just one visit.
A crown is much more expensive to fit and requires at least two visits, as the mould needs to be taken then sent to a laboratory for the crown to be constructed.
So it is natural to look for a treatment which can sit neatly in between.
Something stronger and more durable than a filling.
Yet also something which is easier to fit than a crown and which allows you to salvage the remaining healthy parts of your existing tooth.
This is exactly where onlays and inlays can be included in your dentist’s repertoire.
