If you don't have a crown on at least one of your teeth, you've been fairly lucky thus far. Crowns are remarkably common, with single crowns being the most common restorative procedure. According to GotoaPro.org, it's estimated that about 2.3 million implant-supported crowns are made each year, and that number shows no sign of slowing down in the near future.

With that being said, if you find yourself needing a crown in the future, it's best that you act quickly, before more intense restorative procedures are necessary. Here are some of the main signs that you need a crown for your tooth.

1. You Have a Serious Cavity

One of the biggest reasons why people end up with crowns over their teeth is the dreaded advanced cavity. These often come with severe tooth pain. The problem with advanced cavities is that there typically isn't enough healthy tooth left for a filling. Therefore, a crown needs to be placed over the tooth; the crown is often a better solution than a filling anyway, providing more protection and stability.

2. Your Tooth Is Broken

After teeth become broken, there is often the need for a crown. Obviously, if your more visible teeth are broken, more intense restorative work may be necessary. Crowns can be used for broken molars and other back teeth. Sometimes, it's difficult to see that these teeth are broken. If you recently underwent an injury and feel severe tooth pain, have it checked quickly; you may need a crown for a broken tooth.

3. Your Teeth Are Misshapen

If you were born with misshapen teeth, you may very well need a crown to cover them up. Misshapen teeth can sometimes make it more difficult for people to chew, and a crown can allow them the full functionality that they need. Additionally, this can make smiling easier, and aesthetically pleasing crowns can be used to cover misshapen front teeth as well as molars.

4. Your Teeth Are Stained

Some people's teeth are so stained that they can't be whitened through treatments. In that case, you may want to visit your dental office for crowns. These crowns are often easier to have applied, compared to a number of whitening treatments over the course of weeks.

No matter why you need a crown, if your dentist recommends it, consider their opinions carefully.
