Cracks in teeth can be the warnings of problems to come
Teeth basically have two layers- 
inside and outside of tooth separate with stress and age

These layers expand and contract at different rates.
After a while small cracks appear along the stress lines
formed by heavy chewing and the large termperature changes that go from ice cream to boiling hot coffee.




  Sometime the cracks actually break the tooth.


Broken Teeth Need immediate dental care.

Breaks in the enamel of teeth do not heal-they just get bigger.



 When the inside of a tooth is exposed by a fracture, there can be infections of the bacteria of the saliva into the nerve chamber of the tooth.








 Cracks in teeth do not heal back together.


When you need help with a CRACKED tooth in the



an experienced Go-To dentist is at Yellow Springs Dental Care.











Craze Line



Stop the Fracture from extending into the tooth nerve



Why teeth start to be sensitive--



It isn't smart to ignore early symptoms.









Here is close-up of a molar tooth that has no symptoms...yet.



The large silver amalgam filling in this tooth broke and needed replacement.   All of the old filling has been removed and the deep part of the tooth was visible in this photo.



You can see the two internal cracks have started to grow out toward the surface of the tooth.
There is no decay.



But once a tooth is cracked, it cannot repair itself



Of course injuries to our skin heal because skin tissue can repair itself.



But tooth enamel and dentin lack this ability to heal fractures.  After the tooth erupts, there is no more enamel produced to heal cracks and chips.



The repairs have to be made by a procedure performed by the dentist.

Otherwise, the cracks continue to grow (like a crack in a windshield of a car) until:
they break the surface of the enamel or
2) reach the nerve inside the tooth.



When the internal crack reaches the surface of the enamel, the cracks become visible as "craze lines” on the enamel, but they are invisible to the X-rays 99% of the time.
Craze lines can also start on the outside enamel.  Most of these  thin craze lines that beome visible in the enamel never actually fracture into the body dentin of the tooth.Aged_Front_Teeth.jpgcraze_line.jpg



However, if a visible craze line starts to become stained it is an indication that oral fluids are percolating in and out of the minute fracture line and the break is more at risk of growing deeper and longer.   Eventually the definitive break can occur and the tooth fractures.


White Spots on Teeth


Before a cavity has actually made a hole in your teeth a "WHITE SPOT" appears where the enamel has been injured and lost calcium.  We can rescue the tooth by using Fluoride and Remineralizing Pastes-- and stop the tooth decay before it causes a hole in the tooth.  No drilling-just high-tech Minimally Invasive Dentistry.



Preventive Dentistry is the Best Dentistry













Chewing Ice-One Common Cause of Tooth Fracture


glas%20of%20ice.jpgThe outside tooth enamel and the inside tooth dentin expand and contract at different rates when the temperature of the tooth changes.  this difference causes craze lines to appear because of the shearing forces that occur at the interface between the enamel and the dentin.
One of the most destructive things you can do to a tooth is chew ice.  the frozen ice causes the tooth layers to shrink at differen rates, while simultaneously applying the chewing pressure required to crack the ice.



If the patient bites on the tooth in a direction that tends to close the fracture line there is no pain.
But if the bite is in a direction that opens the fracture line--OUCH!
So incomplete fractures like this do not result in a fragment that breaks off.  And the pain is intermittent, depending upon the direction of the bite.



The fracture line is seen by bacteria in the mouth to be  as wide as an  


Interstate Highway





--and leads straight into the nerve of the tooth.



What To Do?



Early placement of a crown will, usually, stop the further extention of the fracture lines, and may even prevent the nerve damage.  If a crown is place soon enough, it is possible to prevent damage to the tooth pulp and dental nerve.   If the damage to the nerve can be avoided, it may be possible to avoid a root canal episode.



However, when the bacteria in the saliva penetrate the interior of the tooth near the dental pulp it is always the occasion for a toothache. 



 Once the nerve of the tooth is infected, it is an indication that a Root Canal Procedure should be performed to stop the pain and save the tooth.
