Types of Dental Crowns

2016 10 10
A dental crown, also known as a ‘cap’, is a dental restoration which fits over the teeth. Here we take a look at the different types of dental cap or crown.

Getting a dental crown or cap may be necessary to hold onto what remains of your tooth. A dental crown is a man-made fitting that sits on the tooth (which has to be prepared beforehand), to give it the strength and shape of normal teeth. It’s important to note that there is no ‘best’ type of crown, as different types may be suitable for different needs (Source).Temporary or permanent dental crown?

Your dentist may make a temporary dental crown in their surgery in order to retain the structure of your teeth, and protect the underlying tooth and gums. A permanent dental crown, on the other hand, will be made to specifications in a lab, using a mould submitted by your dentist on your behalf. (Source: Dental Treatment Guide).

Metal crowns: These are made from base metals, such as chromium, or nickel, and can handle powerful chewing forces, making it one of the most durable types of crown available. They rarely chip, but the main drawback it their appearance. For this reason, they are a sensible option for teeth hidden away towards the back of the mouth, i.e. molars. In terms of dental crown cost, these are the cheapest available.

Gold Crowns: Not to be confused with regal headwear, gold dental crowns are a surprisingly good option for dental crown material. They are highly durable, and cause minimal damage to surrounding teeth, as well as sitting well with gums. They can potentially give decades of service.

Porcelain fused to Metal: This type of crown is beneficial from the point of view of their being easily blended in to match alongside the tone and colour of existing teeth. They are almost as realistic in appearance as ceramic teeth. A drawback is that they can often chip or wear opposing teeth, and the porcelain covering may become detached from the metal base. The metal may also show through as a dark line at the gumline.

Porcelain / Ceramic Crowns: These types of crown have a highly realistic appearance, matching (or improving on) the look of the original tooth. On this basis, if cost is not an issue, then these are a desirable option.

They can be relatively fragile however, when compared to other types of crown. Patients may also experience sensitivity to hot and cold foods, and they do not have the flexibility of normal teeth.( SOURCE) (Source: Your Smile Becomes You).

People who grind their teeth may have to make use of a mouth guard to stop this from happening at night (Source: Your Smile Becomes You).

Managing the cost of paying for dental crowns can be an unforeseen expense, and taking out a dental insurance cover plan may be an ideal way to meet this need. Check out our range of dental plans for more information.
