Where each one belongs
Neither is better in the abstract. They fail in different ways and they suit different amounts of remaining tooth.
| Consideration | A bonded filling | Full coverage |
|---|---|---|
| What it does structurally | Replaces missing tooth material and bonds to what is left. Relies on the surrounding walls being sound. | Wraps the tooth and holds the remaining walls together against chewing forces. |
| Best case for it | Decay caught while the walls of the tooth are still thick and intact. | A tooth with a crack, thin walls, a very large old restoration, or one treated with a root canal. |
| Tooth removed | Only the decay and enough to bond reliably. | More. That is the real cost, and it is the reason not to do it early. |
| How it typically fails | Decay creeps in at a margin, or the filling chips under load. | Decay at the margin under the crown edge, or the tooth beneath fractures. |
| Visits needed | One. | Two, with a laboratory stage in between and a temporary to wear. |
The cracked tooth problem
The most common reason a tooth needs full coverage out here is not dramatic decay. It is a crack running through a back tooth that has carried a large filling for twenty or thirty years. The classic symptom is a sharp jolt on releasing a bite rather than on pressing down, and it often comes and goes for months before anything visible happens.
Cracks do not heal and they do not stay the same length. Treated early, the tooth is usually saveable with a crown. Left long enough, the crack reaches the nerve or splits below the gum, and then the conversation moves to root canal therapy or to losing the tooth. That is why a vague symptom worth ignoring is worth mentioning instead.
Questions that get you a useful answer
- How much sound tooth is left around this cavity? That is the actual variable.
- What happens if I wait six months? Some answers are "not much" and some are "a great deal", and you deserve to know which.
- Is there a smaller option that would genuinely hold?
- If this needs a crown, how many visits, and what am I wearing in between?
- What made this happen, so the next tooth does not go the same way?
Common concerns
Can I replace my old silver fillings with tooth-colored ones just because I do not like them?
You can, but there is a trade. Removing a sound filling costs tooth structure. Where the existing restoration is intact and the tooth is healthy, doing nothing is a legitimate answer. More on composite fillings.
Is a root canal treated tooth weaker?
More brittle, yes, largely because of how much structure was already missing before treatment. That is why a crown usually follows.
How long does a crown last?
That depends on the bite, on grinding, and on how well the margin is kept clean. No honest answer is a fixed number of years.
