Almost every day we get a call from a patient who has broken a tooth, and generally it means that to save the tooth, we have to place a crown or permanent restoration over it to keep it from breaking further. Sometimes the tooth can't be saved and that is a real bummer!
What causes teeth to break? Well, there are several factors, one of which we see in almost all tooth fractures. The most common contributing factor is Silver amalgam fillings- these fillings have the unique property of enlarging as they age. So, there seems to be some outward pressure on the tooth and if someone bites just the right (or wrong) way, you hear that crack!
Now this tooth broke in several planes at once, and had to be removed; there wasn't enough sound tooth structure to save it! So an implant or bridge needed to be done.
This is a more common sort of fracture. The inside aspect of the tooth just shears away. Luckily, this tooth can be saved with a crown, after first making sure there is no decay present.
The second common factor is bruxism- the habit of grinding or clenching the teeth. Many bruxers break teeth that don't even have fillings in them, but they always have a higher percentage of broken teeth than people who don't brux or clench.
If you or someone you know does grind their teeth and are worried about a tooth or some teeth, don't hesitate to give us a call and we will be glad to check it out for you! Don't wait until it hurts!
