Clenching and night grinding can leave teeth with cracks long before anything breaks. For people travelling from Mississauga, we look at the cracked tooth and the forces behind it, then explain realistic repairs.
Teeth are built to meet briefly during chewing, not to be pressed together for hours. During busy, stressful stretches, many people clench during the day or grind at night without realising it. That steady load can start fine cracks, and one morning a back molar feels tender or twinges on the first bite of breakfast.
The tooth in question may have a crack limited to one cusp, a deeper fracture moving toward the pulp, or damage that has reached the root. Those are different problems with different treatments. Some of the detail may only become visible when an existing filling is taken out or the tooth is looked at under magnification.
We will explain what we can see and what is still a question mark, and we will talk about the forces involved as well as the tooth. Bring up comfort, scheduling, fees and alternatives. A repair is easier to choose when you understand both its purpose and what it cannot guarantee.
Cracks come in many forms. The dentist looks at how much healthy tooth remains, how the pulp is responding, how deep the fracture reaches and what habits may be putting the tooth under strain.
Grinding tends to stress the chewing surfaces of back teeth. When a cusp cracks, the dentist considers whether a limited repair is likely to cope with those forces or whether a restoration covering the cusps would be more appropriate.
Repeated flexing of a cracked tooth can irritate the pulp. Pain that lingers, aching at night and test results help show whether this tissue needs care, in which case an outer repair alone may not resolve the symptoms.
Some cracks run vertically down toward the root or divide the tooth in two, which makes a lasting repair unlikely. Ask what points in that direction and whether a specialist assessment would add useful information.
Even a thorough examination can leave questions open. Ask how the plan would change if treatment reveals more, and how you would be involved before any further step.
For a tooth that can be kept, treatment usually rebuilds the cracked area and provides support suited to the structure that is left. Where the pulp is affected, root canal treatment may be included. Alongside the repair, it often helps to address the clenching or grinding that contributed to the crack.
Teeth cannot knit a fracture back together. A crown or onlay may reduce flexing, yet it cannot promise that the crack will never spread, particularly if heavy forces continue. That trade-off is worth understanding before deciding how much treatment makes sense.

Ask what problem each appointment solves. Protecting the tooth, treating the pulp, placing a final restoration and making a night guard are different tasks that may all appear in one plan.
When the findings support it, keeping your natural tooth may be worthwhile. The dentist should explain why that seems sensible and which factors, including ongoing grinding, make the outlook less certain.
Reviews and clear contact advice help you act if pain comes back or the bite changes. Knowing what to watch for is part of care, even when the tooth feels settled after treatment.
Some cracked teeth need one visit; others need staged treatment, a referral or a protective appliance afterwards. Ask how the sequence relates to your diagnosis and what the tooth needs between appointments.
We review your symptoms, the examination and any images, and ask about clenching or grinding. The dentist describes the crack, whether the tooth seems restorable and what remains uncertain.
Each reasonable option is set out with its purpose, limits, stages and costs. We also clarify how new findings would be handled and which choices might need to be made again.
The repair itself could be a filling, an onlay or crown, or root canal care first. We’ll explain how numbing and comfort are handled, and how gently to treat a temporary if one is fitted.
We check how the tooth meets the others and talk about whether a night guard is appropriate. Ask when normal chewing can resume, which symptoms need a call and what appointments remain.
Your aftercare will reflect the work done and whether the permanent restoration is in yet. Keep your written instructions and the clinic’s number handy, particularly when care is spread over several visits.
A temporary crown or filling is not as strong as the final one, and clenching can dislodge it. Ask which foods to avoid and how to clean around it, and call if it loosens or breaks.
Let us know if the treated tooth feels high, hurts when chewing normal food or develops new symptoms. Please don’t try to grind a high spot down, which can strain the tooth further.
If you clench or grind, the dentist can discuss a night guard and simple daytime awareness. These measures can reduce strain, but they cannot guarantee that a cracked or restored tooth will never worsen.
People often want to know why the crack happened and how to stop it happening again. These answers are general; your examination will guide the details.
Visit our Bronte Street practice for an examination of the cracked tooth and the forces acting on it. We’ll explain what we find, outline the reasonable options and discuss protection before any treatment begins.
If you have severe pain, swelling or a tooth that has just broken, please call so we can advise on availability. Online requests are for non-urgent matters.
