Why Do I Need a Crown After a Root Canal?

crownsDentists often apply crowns to teeth after a root canal procedure to help seal and strengthen it. However, it’s not always that dentists use crowns. In fact, the teeth found at the front of the mouth are often strong enough to not need a dental crown. The same goes for other teeth whose structures weren’t severely weakened by infection or injury and remain reasonably strong after a root canal.

Such cases are rare, though, and even if root canals are meant to save teeth from decay, the procedure can also weaken teeth. This is because infected teeth are treated by removing the pulp and applying filling to replace it. Usually, dentists have to drill through the tooth to remove the infected pulp, which ends up weakening the teeth. This is why crowns are necessary ON TOP of fillings, especially in teeth with large cavities.

When Are Crowns Not Necessary? 

Of course, as mentioned earlier, crowns are not always necessary.

For example, if the incisor and canine teeth are relatively intact, a root canal without crown replacement is okay. This is because the front teeth are not primarily used for chewing, which means they are not as physically stressed as compared to the premolars and molars. Although if the incurs or canines are extensively excavated during the procedure, the dentist may opt to crown the affected tooth to restore its strength.

There are also cases where the premolars and molars are suitable for root canals with no crown replacement. Although, it is only usually possible if the said teeth are at low risk of fracture, such as when cavities aren’t large enough to require extensive excavation during the root canal. In such cases, silver or composite fillings alone are strong enough to seal the chewing surface of the premolars and molars.

Crowns Are Very Important 

Because of how root canals work, though, dentists often recommend placing crowns on top of applying permanent fillings. This is so as to provide proper protection to affected teeth, while at the same time, restoring its strength and appearance as well. Remember, treated teeth without crowns are at a much higher risk of fracture than those with crowns.

Of course, whether or not you have your teeth covered by crowns or not, it’s important that you continue to take proper care of your teeth. Remember, your teeth are still vulnerable to tooth decay. Make sure that you protect your natural and treated teeth properly by brushing twice a day, flossing and visiting the dentist regularly.

Speaking of the dentist, these oral health care providers can help you choose the best option to restore your tooth after a root canal procedure.

Just keep in mind, even though the front teeth does not always need a crown for strength, its appearance can greatly benefit from a crown. Also, even if the treated molars or premolars are not at a high risk of fracturing, a filling-only restoration just doesn’t provide the necessary protection and improved appearance that a crown does.
