Filling or Crown? When a Filling Is Enough and When a Tooth Needs a Crown
Not every decayed tooth needs a crown, and not every large filling holds up. Here is the difference between a filling and a crown, and when each one is the right call.
A note from our clinic
We keep as much natural tooth as possible. If a filling can do the job well, we will not suggest a crown; when we do recommend one, we show you on the X-ray or a photo exactly why the tooth needs that extra protection.
Short answer: if the decay or break is small to medium and the rest of the tooth is strong, a filling is enough and keeps as much natural tooth as possible. If a large part is missing, or a back tooth has had a root canal, a crown protects it from breaking.
Our rule is simple: keep as much natural tooth as we can. A crown means trimming the tooth on all sides, so we only suggest one when a filling will not hold.
Side by side
| Tooth-coloured filling | Crown | |
|---|---|---|
| Suitable damage | Small to medium | Large, or a weakened tooth |
| How much tooth is removed | Only the decayed part | Trimmed on all sides |
| Visits | Usually one | Two or more |
| Protection against fracture | Limited if the filling is very large | High, because it covers the tooth |
| Cost | Lower | Higher |
When a filling is enough
- ✓The decay has not reached half the tooth or more.
- ✓The walls around the filling are thick and strong.
- ✓A small chipped edge or mild wear.
When we suggest a crown
- ✓A large part of the tooth is gone and the filling would be most of the tooth.
- ✓A back tooth that has had a root canal. It is weaker and can split while chewing.
- ✓A tooth with visible cracks, or one that has broken more than once.
- ✓A very large old filling that keeps breaking and being redone.
Root-canal-treated teeth
Many people have a root canal and stop at a filling, then a year or two later the tooth splits and cannot be saved. For back teeth especially, a crown after root canal treatment is usually what protects that investment.
Frequently Asked Questions
Does a crown always need a root canal?＋
No. Many teeth are crowned while the nerve is alive and healthy. A root canal depends on the nerve's condition, not on the crown itself.
How long does a tooth-coloured filling last?＋
Many years with good care, but very large fillings tend to have a shorter life because they carry more load.
What is the best crown material?＋
It depends on the tooth. Front teeth need a natural-looking, tooth-coloured material; back teeth need more strength. That is decided after the exam.
