After root canal treatment: crowns or direct resin?

[lococo399]

I have a cavity on my front tooth, which requires root canal treatment apparently.

I've talked to my local dentist, who has very good experience, and he told me that he does not use direct resin to front teeth (under any circumstances) after root canal treatment, but always uses crowns.

My question is, is this common procedure among the professional dentists today?

If not, then why my dentist does not use direct resin at all for front teeth?

Crowns for front teeth after root canals are more risky than for back teeth. But back teeth will always need an onlay or a crown after RCT.
Where a front tooth has died from a traumatic experience, e.g. blow to face, then a direct composite is needed to only fill up the access cavity - there is enough natural tooth structure to hold the tooth together. Where the front tooth has died and weakened from caries, then a crown (with cast post? and core?) may be slightly better than simple composite.
