Similar to broken teeth and chipped teeth, cracked teeth can often be the source of toothache.
However in this instance cracked teeth are more commonly seen by your dentist during an examination when they are very small and will be undetected by you otherwise.
This is because many teeth can develop small cracks over time, some of which never require treatment and will only need some monitoring whereas others may spread and cause a portion of the tooth to break.
Has a small piece of tooth ever broken away from one of your teeth containing a filling?
This is quite a common scenario with the amalgam (silver-coloured) filling material since small cracks would develop in and around the filling and over time this would get bigger but would only be noticed once a piece of the tooth had actually broken away.
It is therefore vital that you attend your dentist regularly to ensure that these cracks can be detected early and simple procedures such as some bonding over the crack or a replacement filling placed with a tooth coloured material can be done.
Cracks are a potential source of serious future toothache even if they are small so don’t ignore them!
Serious breaks — These breaks go deep enough to expose the nerve. They almost always cause the toothache and be very sensitive. Usually, the broken part of the tooth will bleed. If this is the case you will need root canal treatment to remove the exposed nerve and possible an onlay (hat for the tooth) or crown (crash helmet for the tooth) to restore the tooth to normal function so you can eat and chew properly.
Advice: Get any cracked teeth checked out by your dentist!
