WHAT IS A DENTAL CROWN?
A dental crown is a tooth-shaped “cap” that is placed over a damaged tooth to restore its shape, size, strength, and to improve its appearance.
When a crown is cemented into place it encases the entire visible portion of a tooth which lies at and above the gum line. A crown can restore a broken tooth or teeth that have been severely worn down. A crown can also be used to hold together parts of a cracked tooth or cover misshaped/discoloured teeth.
Could a dental crown be right for you?
Although fillings are a great solution for cavities in the tooth, in some cases a crown is a better option where damage is more severe. There are a range of reasons why you may need a dental crown, including:
- If you have a weak tooth from decay, which is broken or cracked
- If you have severely worn down teeth
- If you have minimal natural tooth remaining
- If you have a dental bridge, crowns can help to hold this in place
- If you have discoloured or misshapen teeth

Frequently Asked Questions
How much tooth is needed for a crown?
Crowns can be fitted on damaged teeth, even where there is very little natural tooth left. That’s why they are a popular option for when a filling is no longer viable. Dental crowns can be placed where there is as little as ¼ of the natural tooth remaining.
As long as there is enough tooth to cement the crown down, then you should have no issue having a crown fitted.
Is it painful to have a crown put on your tooth?
Similarly to having a filling fit, a crown is placed on a damaged tooth after the area has been completely numbed. That means you shouldn’t experience any sort of pain or discomfort during the process itself. You may experience some mild discomfort in the days to follow, but this should ease after a couple of days.
How long do dental crowns last?
Dental crowns typically have a decent lifespan and can even last up to 30 years if well looked after. The general lifespan of a crown may differ slightly, depending on where abouts in the mouth has been placed. In some cases, your crown could last a lifetime, whilst others could crack and need replacing.
Can your tooth rot under a crown?
In some cases, yes. If a patient has a poor oral hygiene routine, there is a higher risk of plaque and bacteria forming, and as there is natural tooth below a crown, there is the risk of this decaying.
In these circumstances, the only solution would be for the crown to be removed and the decay to be dealt with before having a brand new crown fitted.
