How long do crowns last on front teeth: A comparison between different tooth replacement options
If you lost a tooth or a group of teeth, or suffered a knock to your front teeth and a piece got broken off, then you are definitely seeking replacement, and you are not alone. If you are seeking tooth replacement, you have no doubt wondered
what are the possible ways of restoring these missing teeth, and no doubt again that this question came to your mind” How long do crowns last on front teeth, and how about the back teeth?”
How long do crowns last on front teeth?
The reason we are singling out front teeth is because they are more commonly in need of a crown to cover them since they are smaller and weaker than back teeth, and also because they make up the smile – which for some unexplainable reason is more important nowadays than the ability to chew – and therefore people are more likely to protect them or replace them if they are lost or broken.
In general, the life expectancy of crowns and bridges ranges anywhere between 8 to 12 years from the time they are made. After that period, you need to check if they have problems or need to be repaired or even replaced. Of course that doesn’t mean that 12 years is the maximum a crown or bridge could stay in your mouth – I had patients with bridges that were made more than 30 years ago and are still incredibly strong and presented no problems at all !! – but that is the right
period at least for a check up on them.
After that period, a few problems could arise, among which are:
So who needs a crown?
Crowns are ways of protection of a tooth, so a tooth that is weak and need of strengthening needs a crown, examples of such cases are:
What about bridges?
Bridges are essentially 3 or more crowns joined together to span an empty space. Bridges have been around for ages, and are still very usable in modern dentistry. With the advancements in technology, bridges have become more natural looking and feeling, and their durability increased significantly.
Bridges are only one way to replace missing teeth. Other methods include:
What are crowns and bridges made of?
There are 3 main categories of crowns and bridges:
Metal with porcelain covering:
The core is made of metal (the part that fits the tooth) and is covered by a few layers of porcelain to mask the silver color of the metal, and give the tooth its natural appearance and functionality.
Zirconium with porcelain covering:
Same deal, but instead of metal, Zirconium is used. Zirconium (you might know it as fake diamonds) is an incredibly strong, inert and durable material similar to metal, with the added advantage of being white in color, so you would expect the esthetics to be a lot better.
All porcelain crowns:
The most modern advancement in the field. Crowns and bridges nowadays are almost all made of porcelain with no metal or zirconium core. This is because the research that went into the matter have made incredibly strong porcelain, plus they are made using computer guides, so the accuracy is far greater.
Final thoughts .. Edentulism (having missing teeth) is a global phenomenon. Almost everybody around the globe has suffered a loss of one or several teeth, probably due to lack of care and the ever popular opinion of “so what if I lost a tooth, I still have another 32 to chew on”. Nothing – and we mean nothing – could ever replace a natural tooth in its feel, comfort and naturality, so in this case “prevention is better than cure” takes a quite literal meaning.
However, if the deed already happened, seek to replace these as soon as you can. Don’t waste your time by asking questions such as “how long do crowns last on front teeth” and “are crowns permanent” because a missing tooth is a disease, and if you are uncomfortable with crowns and bridges, just pick something better suiting your taste.
