Is it time to replace your crown?
I’m routinely asked how long crowns last. My answer is always the same.
I don’t know.
The longevity of a crown is dependent on a number of factors. Any one of these can lead to a crown needing to be replaced. I tell my patients a well-made crown that is taken care of should last up to 10 years, in my opinion.
How well a crown is done plays a big role in how long it will last. Poor fit, thin porcelain, poor bite or contacts between the adjacent teeth can contribute to premature failure. Unfortunately, a patient may not know there is an issue until problems surface.
As with anything, the better something is taken care of the longer it will last. Crowns are no exception. Poor diet, poor oral hygiene or missing regular dental check-ups can shorten the life span of a crown. Decay, periodontal disease and neglect are a death sentence for a crown. So, don’t miss your routine dental visits.
For patients who do all the right things - normal wear and tear is the most common cause of crowns needing to be replaced. With some of the older crowns, chipped and broken porcelain will warrant replacement. Gum recession which exposes the crowns margin is another reason for replacement. When the margin is exposed the natural tooth will wear more easily than the harder porcelain. This will cause a gap to form under the crown margin allowing bacteria to collect which can lead to cavity formation. At this stage it’s a good idea to have crowns replaced before bigger problems form.
