Cracked Tooth Treatment in North York
A cracked tooth can cause a quick, sharp pain when you chew that comes and goes. Finding and treating the crack early gives the tooth a better chance.
Cracked tooth treatment in North York at Emerald Forest Dental depends on where the crack is and how deep it goes. A small crack may be bonded or covered with a crown. A crack that reaches the nerve may need a root canal, and a split tooth may need removal. Early diagnosis often keeps treatment simpler.

About cracked tooth treatment
Teeth can crack from grinding or clenching, biting on something hard like a popcorn kernel or ice, large old fillings that weaken the walls of the tooth, or a blow to the face. Back molars are most often affected because they take the heaviest chewing forces. Many cracks are too small to see in a mirror and do not show up clearly on X-rays.
A classic sign is a sharp pain when you bite down, or more often when you release the bite. The crack flexes open, the inner part of the tooth is irritated, and then it closes again. You may also feel a twinge with cold. Because the pain comes and goes, it can be hard to pin down which tooth is the problem. Your dentist may use a special bite tool, a light that shines through the tooth or a dye to find the crack.
Cracks generally do not heal, and they can grow over time. Treatment aims to hold the tooth together and stop the crack from spreading. Very fine surface lines in the enamel, often called craze lines, are common and usually need no treatment.

- Protect the toothTreatment may be bonding, a filling, an onlay or a crown to hold the tooth together.
- Treat the nerve if neededIf the crack has reached the pulp, a root canal may be done before the crown.

Other options
If a crack runs down into the root or splits the tooth in two, the tooth usually cannot be saved. In that case, your dentist will talk with you about removing it and the options for replacing it, such as an implant or a bridge.
Cost and coverage
What you pay for a cracked tooth depends on the treatment it needs, which can range from bonding to a crown, and sometimes a root canal as well. Ontario dentists commonly use the ODA suggested fee guide as a reference. Many insurance plans cover a share of this care, and our team can help send a pre-treatment estimate. If you have CDCP coverage, ask us how it may apply. LendCare payment plans are available for larger treatment.
Our promise: we confirm your coverage and explain the cost before treatment.

Cracked Tooth Treatment FAQ
Can a cracked tooth heal on its own?
No. Unlike a broken bone, a crack in a tooth does not heal. Treatment can protect the tooth and keep the crack from growing, which is why it is worth having it checked early.
Why does my tooth hurt only when I stop biting?
When you bite, the crack can flex open slightly. When you release, it snaps closed and irritates the nerve inside. That pain on release is a common sign of a cracked tooth.
Will I need a root canal for a cracked tooth?
Not always. If the crack has not reached the pulp, a crown or onlay may be enough. If the nerve is inflamed or infected, a root canal may be needed before the crown.
How can I prevent cracked teeth?
Avoid chewing ice, hard candy and pen caps, and wear a mouthguard for contact sports. If you grind or clench at night, a custom night guard can reduce the strain on your teeth.
Is a cracked tooth an emergency?
A crack with mild, occasional pain should be seen soon but is not always urgent. Severe pain, swelling or a piece of tooth breaking off should be checked as soon as possible, so call us.
